240hz backlight strobing

Posted by & filed under Uncategorized .

No. This requires approximately a ~1500cd surge of a flash from the edgelight which is already possible with newer LED’s, and by being on 25% of the time, would average down to about 350cd. Alternative to PWM-free: For display electronics incapable of being PWM-free, the use of high-frequency PWM can be used as a substitute to PWM-free. Having backlight strobing only at fixed refresh rates is a major limitation of the technology in my eyes, so I appreciate Asus trying to innovate to fix this significant downside of using strobing. Different people will have different flicker detection thresholds, so a reasonably high-percentile needs to be achieved (e.g. eliminate the need for custom overdrive algorithms at lower refresh rates, eliminate the need to use a large blanking interval). When refresh rates begin to enroach the pixel transition limitations of the LCD, the pixels at the bottom edge are far fresher than the pixels at the top edge, and thus begin to require different overdrive treatment to eliminate crosstalk (double-image effects) problems between refreshes. Simpler algorithm variations are also possible (e.g. The former only measures transition-related ghosting, while the latter also captures tracking-based motion blur. These are the main useful tests for strobe backlight improvements. Likewise, the flashes between between adjacent scanning backlight segments severely reduces the achievable motion blur reduction you can get with a scanning backlight. It is also noteworthy that there is also a market for 240Hz-native-refresh displays, for people who dislike flicker of all forms and prefer a 240Hz flicker-free display. A lot of motion blur is already eliminated during backlight strobing, especially during short strobes, that the shape of motion blur of a strobe-backlight display is typically not noticeable at these levels. The tinkerer community (e.g. UPDATE: Eizo has released the gaming version of this monitor, the Foris FG2421. Though I’d like to know if there is a perceptible difference between a regular 120hz IPS and this one to justify the (5-fold? That’s about all we can think of. Such older LCD’s should be avoided for strobe backlight conversion projects. Several issues have been found with scanning backlights, from the perspective of a homebrew modification: (1) Backlights are way more inefficient than edgelights. It’s also possible to shorten the LightBoost strobes, so that the backlight flashes for a shorter time period. What’s more important is successfully achieving high quality strobing. Dell SE2719HR. This way, two passes of a refresh occurs, which usually leads to even cleaner refreshes. A 480fps+ camera is ideal (e.g. When most of a pixel transition is quicker than a refresh cycle, tracking-based motion blur becomes more dominant than ghosting-related motion blur (caused by slowness of transitions). This site uses Akismet to reduce spam. Some companies such as VPixx specialize in solving this problem. ULMB/LightBoost style backlight strobing). For example, refreshing the LCD panel two times on the same image (one refresh from computer converted into two duplicate panel refreshes), before strobe-flashing during the clean period at the end of the second-pass refresh. I soldered the grey wire ( for 33k LB resistor) on the driver to the green controller wire. Although this model is targeted at GIS/mapping, this could potentially become an excellent casual-gaming 120Hz monitor with great color! A 240Hz native refresh rate (flicker free, no strobing) which would have the equivalent motion blur of a strobe-backlight display utilizing approximately 4ms strobe flashes. NVIDIA LightBoost, EIZO Turbo240) have been found to have less motion blur than current 2013-model OLED HDTV’s. 2. In motion tests on a LightBoost monitor (with LightBoost activated), when using the monitor OSD menu to quickly alternate between LightBoost=0% (use monitor OSD, set LightBoost to one setting below 10%, which uses a longer but dimmer strobe) and LightBoost=10% (shorter but brighter strobe) while viewing motion tests at TestUFO. As of this writing, research is being done on any prior art, to determine whether anyone dynamically considered blending from PWM-free to square-wave strobing. Many of our readers crave perfect motion clarity. During 2013, several display manufacturers began to contact Blur Busters asking to add/improve/beta test a strobe backlight to their monitors (contact info for free help). One overdriven refresh in the dark, unseen by the human eye, followed by a single backlight strobe flash on a very clean 120Hz refresh. Source Engine games such as Counterstrike and Team Fortress 2) for an excellent technical demonstration of the incredible flicker-free motion fluidity that 240fps@240Hz would give. HDGuru, japanese scientists, etc) to fall greatly short of mainstream expectations, at least on large-screen format OLED displays. Upon studying the Eizo FDF-2405W manual for Eizo’s upcoming monitor, there is good news on page 15: Reducing motion blur “Blur Reduction” Motion blur occurs when the eye recognizes liquid crystal transitions which comes from changing screens (frames). For a homebrew hack, you may not get as good as LightBoost in motion clarity, especially if you mod an IPS computer monitor instead of a TN computer monitor. Such advanced extras can be included and publicized to allow crowd sourced calibration/improvements of your computer monitor. However, it is not a complete representation of commonly perceived display motion blur and motion artifacts, because stationary camera excludes tracking-based motion blur. FW900) have slower decay times than modern LCD pixel transition times in today’s 1ms panels. If you are experimenting with high refresh rate LCD’s (e.g. This is even despite the fact that many medium-persistence CRT phosphors (e.g. I’ve got plenty of room to increase the output if needed, but I like around 90cd/m^2. When “Blur Reduction” is set to “On”, the backlight flickers in sync with liquid crystal transition*1 so the change cannot be seen, thereby achieving clear images with less blur. In this motion test, look at the windows in the buildings of the Moving Photo test; the window frames get more motion blurred with 2.4ms strobes than 1.4ms strobes during 1920 pixels-per-second motion! Once pixel transitions completely fit within the “OFF” period, there’s no upper limit to motion clarity of LCD — motion is as clear as how briefly you flash the backlight. It is important to gain an understanding of how LCD panels refreshes. New TestUFO motion tests are being developed; if you require a specific specialized TestUFO motion tests, contact mark@blurbusters.com to send suggestions of additional motion tests and improvements that are needed. With 250 watts of LED’s, it only gets about double the brightness of a 25 watt edgelight already built into a typical modern panel. Modern LED backlights are able to be flashed very fast. Other displays also use strobe backlights, such as NIVIDA’s ULMB, BenQ’s DyAc, or Sony’s low-lag Motionflow Impulse used in Game Mode. At 1440 pixels/second motion during LightBoost=100%, the castle windows at the top becomes slightly blurrier (about ~1.5 pixels of extra motion blur). That depends on the strobe length, one backlight flash per unique refresh/frame. Strobe backlights can create some minor input lag because you are waiting for the whole LCD panel to finish refreshing before strobing the backlight. This will be clearly noticed in certain motion tests such as www.testufo.com/blurtrail during strobe curve manipulation experiments. Advanced Strobe Crosstalk FAQ Schematics for Overriding a LightBoost Strobe European Researcher Marc Repnow’s LightBoost Site ToastyX Strobelight; Enable LightBoost independently of nVidia Drivers TestUFO: Blur Busters Motion Tests. perfectly completed OLED pixel transitions) but more motion blur (e.g. to account for the freshness of pixel transitions before strobing. For computer programmers with the Arduino 1.8.2 IDE, the backlight strobing microcontroller is fully programmable with custom 4-segment scanning backlight modes: Custom strobe pulse length (good for reducing motion blur, in a brightness versus blur trade-off) Custom strobe phase (good for adjusting position of strobe crosstalk) Overvoltage boost for brighter strobing at shorter … All of these monitors are sourced from LG and are certified by HDR600. aiming for >90% of people not seeing side effects from the variable-rate strobing). They have the VIEWPixx Scientific Research 120Hz Monitor with a scanning backlight with little backlight diffusion (measurements). If you choose to do motion blur measurements using a camera, this section becomes important to more easily understand the correlation between various motion blur measurement methods, and human perceived motion blur. No-latency, integer-scaling solution is ideal for responsiveness. It’s possible to have a situation where you have less ghosting but more motion blur, or vice-versa. You avoid flicker at lower frame rates, and you get full strobing benefits at higher frame rates. It should give you the best experience possible, without dominating your desktop. Pursuit Camera: Accurate Capture of LCD Motion Artifacts. The trigger framerates may be different from the examples (or may even be adjustable via a user flicker-threshold setting), but the concept is the same. Some new display technologies such as OLED are prone to the motion blur problem (see Why Do Some OLED’s Have Motion Blur?). However, for many people, the faster human reaction time from reduced motion blur outweighs the minor added input lag, especially at higher refresh rates (120Hz). With strobe backlights, you have no limiting factors in motion clarity: (1) Not limited by LCD pixel transition speed anymore, as long as pixel transition speed is far less than one refresh cycle long. That said, prototyping an algorithm on a GPU can be a good source of experimentation before creating firmware that gets permanently installed on a computer monitor. This would make motion blur roughly equivalent to a LightBoost monitor running LightBoost=60%, The #1 Site of Everything Better Than 60Hz™, © 2020 Blur Busters | Theme by jor-folio.com, MSI Launches Monitor Console Mode with Selected Monitors, Two New Acer Gaming Monitors Emerge Across Markets, the XV282K KV and XZ270U P, JVC’s Enterprise XR Headset at Highest Per-Eye Resolution, The ASUS VG34VQL1B Ultrawide Gaming Monitor Set to Compete, Blur Busters Law: The Amazing Journey To Future 1000Hz Displays, GtG versus MPRT: Frequently Asked Questions About Pixel Response On Displays, The Basics of Network Lag – with Battle(non)sense, turns on the backlight only for the stable duration of the second image, Motion Blur Reduction (ULMB, LightBoost, etc), Reviewers using Blur Busters Testing Techniques, Strobe Crosstalk: Blur Reduction Double-Images, DIY Firmware Upgrade For BENQ Z-Series [2014], Strobe Utility for Calibration of BenQ/Zowie Blur Reduction, G-SYNC 101: G-SYNC vs. V-SYNC OFF w/FPS Limit, G-SYNC 101: G-SYNC vs. V-SYNC w/FPS Limit, G-SYNC 101: G-SYNC Fullscreen vs. Borderless/Windowed, G-SYNC 101: In-game vs. in-house utilities), or third party utilities including utilities designed and created by Blur Busters (contact info). LightBoost displays use only lookbehind during response time acceleration. Brightness curves can even be created by dynamically changing PWM. Requirements for Factory / Outsourcing / Electronics, Requirements for Monitor Firmware Programmer. But the manual suggests that the strobe only occurs at the clean period of the second refresh, which suggests the strobe is shorter than 1/240sec. Stationary Camera: Capture of Pixel Transitions. First, see the Scanning Backlight FAQ that I (Mark Rejhon) created. An advantage of 60Hz is more safety margin for LCD pixel transitions, and less GPU is required for 60fps @ 60Hz. Presently, certain gaming monitors that utilize the better strobe backlights (e.g. Be noted that not everyone like strobing (flicker) so the strobing mode should ideally be adjustable and easily disabled (to continuously shine the backlight, and return to regular sample-and-hold, with the motion blur disadvantage). Amplified inversion artifacts, as seen in Lagom pixel-walk and TestUFO: Inversion. A big advantage of software-based response-time-acceleration is it can be used on any LCD panel (with its hardware response time acceleration disabled), so this makes a good manufacturer prototyping platform for response time acceleration algorithms, before being ported to LCD controller firmware. This is because pixel transitions are now much shorter than the refresh length. This reduces eyestrain for flicker-sensitive people. One of the techniques discussed, was the use of strobing to reduce persistence. Alternatively 180Hz PureXP + RetroArch 2:1 60Hz Software BFI (new feature) For best any-LCD I've ever seen, try Oculus Quest 2 VR + Switch 72-to-60Hz + Virtual Desktop + MAME HLSL, to put a floating realistic virtual CRT … Millisecond-scale and sub-millisecond-scale strobe lengths are more pratical, resembling short-persistence CRT phosphor). The 60Hz will give you more strobe timing margin than 120Hz, but you may still get more ghosting than LightBoost, due to the lack of ability to modify the LCD controller for Y-axis-compensated RTC algorithms. A monitor manufacturer running on a tight budget, could also theoretically do the custom firmware later (or hire an outside enthusiast programmer from the Blur Busters gaming community, contact info). Banding easily appears during LightBoost mode in the full-screen TestUFO Flicker Test, which shows math rounding errors in Y-axis compensated RTC. This covers information about scanning backlights. Modern non-strobed LCD panels create tracking-based motion blur more similar to linear motion blur instead of gaussian motion blur. Motion Blur Reduction for displays (ULMB, LightBoost, DyAc, ELMB, etc) are now very common on modern 120Hz+ gaming monitors. CRT phosphors can ‘flicker’ at ~5000cd to compensate for the dark period between refreshes, so we’re getting “there”). For that use case, avoiding visible flicker is more important. I think the LB black on my monitor might have been worse than what’s normal. These simplified requirements below allows quicker and simpler firmware modifications, to support quality strobing. For example, turning a 1:2000 panel into a 1:20,000 panel, for ANSI checkerboard contrast (a screen that simultaneously shows blacks and whites) because of this backlight diffusion. Backlight strobing Emulated sRGB mode LFC support NVIDIA G-Sync Compatible Pixel-perfect upscaling Variable overdrive * * Die neuesten Vergleiche, darunter Eve Spectrum QHD 240Hz Die neuesten Vergleiche, darunter Eve Spectrum QHD 240Hz, die von den Website-Besuchern gemacht sind. (NOTE: TFTCentral has oscilloscope graphs of the shapes of LightBoost strobe curves) You only see subpixel-changes modulations in motion blur (less than 1 millimeter change in motion blur trail, during 960 pixels/second motion). First, make sure you got your circuit boards supporting strobing in the minimum possible way (see above). (C) The further you move back the LED’s, diffusing becomes easier but you lose contrast ratio between ON segments and the OFF segments; the more leakage between segments. G-SYNC) while avoiding side effects. Screen seems fairly uniform and has no backlight bleed. AOC Q27G2S. An interesting question is the strobe flash length, as shorter strobe flahes results in less motion blur. The colors and contrast ratios are better for the msi. It is wholly possible that your LCD panel already supports this. (Credit: “Evaluation of an organic light-emitting diode display for precise visual stimulation“). 100x100mm … | Blur Busters, High Speed Video of Sony Trimaster OLED | Blur Busters, CONFIRMED: nVidia G-Sync includes a strobe backlight upgrade! Observe the differences in motion blur in the windows of the castle at the top of the moving photo. Eve Spectrum QHD 240Hz. And other advantages: (3) It’s easy to do with an edgelight (4) It’s far more efficient, less power. It is actually theoretically possible to get far better motion resolution with LCD than with CRT if you’re able to successfully flash a ultrabright edgelight for an ultrashort time period, shorter than a typical CRT phosphor decay time (illuminate-and-decay cycle). a two or three refresh history) for best results. Things like temperature and panel differences can also affect LCD pixel transitions, so some of this is done on a best-effort basis, or even the addition of temperature sensor data into response time acceleration calculations. No human side effects would seem to be noticeable by using trailing frame history to compute strobe curves, as long as these conditions are met. An idea that Mark Rejhon of Blur Busters has come up with is a new creative PWM-free-to-strobing dynamic backlight curve manipulation algorithm, that allows variable-rate backlight strobing (LightBoost), without creating flicker at lower frame rates. Industrial design style. I spent many years going through potential 1440p successors to that monitor only to end up disappointed over and over again. We’re excluding stroboscopic/wagonwheel effects which is worse at lower Hz; and comparing sample-and-hold motion blur — the type you see at http://www.testufo.com/#test=eyetracking — it actually becomes rather simple once a person understands how sample-and-hold motion blur works. Ideally, the strobe backlight operate at any refresh rate, even all the way down to 60Hz (for emulator and console use), while allowing strobing at higher refresh rates (to reduce flicker). To get one-quarter motion blur -- you have to quadruple the refresh rate (and framerate) or add 25%:75% ON-vs-OFF strobing (e.g. “X” is the persistence value, for the length of the off-on-off cycle (not transition time, e.g. LG CX OLED with BFI is your best bet for a real CRT successor in terms of motion clarity. 3 Comments For “Eizo 240Hz VA monitor uses strobe backlight. A stationary camera is good for photographing pixel transitions statically. This is what LightBoost does, as seen in the below popular high-speed video (which is also proof that it is now possible ot have LCD’s with CRT motion quality): With all-at-once strobing, you can even use a simpler and more efficient edgelight. The higher the refresh rate the better. Added two ASUS TUF gaming monitors with ELMB-Sync (simultaneous VRR and backlight strobing) and a 17″ 240Hz IPS portable monitor, the ASUS ROG Strix XG17. A higher refresh/ rate/strobe rate is preferred where possible. Mehr lesen. Stationary cameras/eyes behave differently from moving cameras/eyeballs that are tracking motion. Pixels transitions at the bottom edge of the screen will typically be fresher and less complete than pixels at the top edge of the screen, so experimentation of adding Y axis math to the response time acceleration is very desirable for high-refresh-rate strobe backlights. Similar to other BenQ ZOWIE monitors, the XL2546 borrows design elements from previous monitors. Higher refresh rates require extremely powerful GPU’s, though 240fps is easily achieved on modern GPU’s in older games (e.g. (That strobe length is currently economically doable at their quoted average ~350cd with a brief boost voltage to an overengineered LED edgelight. In fine-tuning the strobe length, you may be interested to know that most humans are able to tell apart 1ms from 2ms under ideal conditions in Blur Busters Motion Tests (Moving Photo) — If you test this in Chrome browser on a 120 Hz LightBoost monitor, then even human eyes can still see a noticeable difference between LightBoost=100% (2.4ms strobes) and LightBoost=10% (1.4ms strobes). I connected the driver’s connector pin for the green (for the 11k LB resistor) wire to ground, to ensure it was disabled (unnecessary really). Ideally, strobing should be refresh-rate adaptive. Read more. No interpolation.”. A disadvantage of 60Hz is more flicker than LightBoost. The rest of the details can then later be handled by a software programmer creating a custom monitor firmware. These requirements shifts most of the complexity of adjustment/calibration fine-tuning to the end-user, or during later-stage in-house experimentation (e.g. In addition, if your project has benefited from the information on this page, please let us know! 240Hz), you may need to factor in more than one previous refresh in the calculations for response-time acceleration algorithm (e.g. Although custom strobe-optimized response time acceleration algorithms would be ideal, a multipass refresh may simplify strobe backlights for homebrew situations (e.g. Modifying an existing fast 60Hz LCD (<= 2ms), to strobe its existing LED backlight, is simple for an experienced electronics hobbyist equipped with the necessary tools and knowledge, as shown above. bmg on HardForum made a successful modification to create a brighter LightBoost: I finally got around to opening up my VG248QE.
