FW900) have slower decay times than modern LCD pixel transition times in today’s 1ms panels. In my gaming/tv room that has subdued lighting, I’m currently at .12cd/m^2 minimum LCD output, and 89cd/m^2 max, that’s with LB20 and Contrast 90. Fully certified and tuned by Blur Busters, PureXP blur reduction utilizes backlight strobing, drastically improving left to right motion image clarity for clear visuals in fast-moving objects. DDC commands to customize response-time acceleration, to allow third party software to create custom lookup tables for the monitor). First, make sure you got your circuit boards supporting strobing in the minimum possible way (see above). Many of our readers crave perfect motion clarity. If you do get a high speed camera, a good test pattern for high speed camera use, is Blur Busters Motion Test (Flicker) which can help you determine how they refresh, and to help you with timing the strobe backlight flashes. Square-wave strobes creates linear display motion blur, while sine/gaussian-wave strobes creates gaussian display motion blur. Another need is to eliminate banding when using Y-axis compensated overdrive algorithms. In addition, strobe backlight modes can simply be configured/disabled via monitor menus or graphics drivers, for those input-lag-critical situations or personal preference. These technique utilize strobe backlights as the method of blur reduction. nVidia has licensed a strobe backlight technology called LightBoost to display manufacturers. i Truly belileve this is the fastest 240hz IPS monitor right now. However there being the Zowie XL2546 (and other 240hz monitors) I'm not sure if I should stick with the 2540 now or return it to get a different monitor. It is wholly possible that your LCD panel already supports this. Here, the ghosting becomes faint enough to disappear in the noise floor of the on-screen motion (e.g. This is even despite the fact that many medium-persistence CRT phosphors (e.g. There is a pixel-perfect upscaling feature in this monitor for low resolution input signals. It’s also possible to shorten the LightBoost strobes, so that the backlight flashes for a shorter time period. Some 120Hz panels exhibit distortions when viewing TestUFO: Moving Inversion Pattern. LightBoost monitors use. No. This is because several existing raw 120Hz LCD panel assemblies are now fast enough to be strobed, using existing edgelights, without any panel modifications. factories in China) may not understand motion blur reduction via strobing either. This is a side effect that needs to be considered, as overdrive algorithms for strobe backlight use, can be different from overdrive algorithms used in PWM-free mode, considering the use of Y-Axis Compensated Overdrive algorithms being used. 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). And you will get a LOT more flicker, because it’s 60Hz flicker, not 120Hz flicker. (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. The whole screen becomes one big matrix math array (separately for each R, G, and B) that’s run on the GPU in real time, to create compensated color values. This covers information about scanning backlights. The typical brightness can go up to 450cd/m 2, while the peak brightness is 750cd/m 2. LG 27GL83A-B. Your eyes are actually witnessing the motion clarity difference of 1.4ms strobes versus 2.4ms strobes! This requires careful and precise strobe-length control during variable refresh rate, as the display now refreshes dynamically on demand rather than at discrete scheduled intervals. If you keep the LED’s close to the LCD panel, you can get about 20:1 contrast between the off-segments and on-segments. This may be one possible technique of achieving modded 60Hz or 72Hz LightBoost with potentially better color quality. Your monitor should be as inspiring as your adventures. With nVidia’s G-SYNC announcement, variable refresh rate displays are now a reality today. Also, it may be feasible to use a 3D printer to print parabolic reflectors for LED ribbons (and then using metallic paint or electroplating). Games are much more demanding than television/movies, as detection of motion blur is much more sensitive in these situations. There are people (including myself) who prefer playing games on a CRT 85fps@85Hz, because it still has less motion blur than LCD 120fps@120Hz. 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. And so on. Strobe backlights can create some minor input lag because you are waiting for the whole LCD panel to finish refreshing before strobing the backlight. That gives a modest current boost any time lightboost is enabled. This can be an issue for some high-end competitive gamers. OLED persistence was shown by scientists and testers (e.g. For further discussions, or custom TestUFO motion tests, or contact mark@blurbusters.com. Pursuit Camera: Accurate Capture of LCD Motion Artifacts. LightBoost hacking is *much* easier, and has been done by a few people to brighten and improve LightBoost backlights, by changing a few resistors. NVIDIA LightBoost, EIZO Turbo240) have been found to have less motion blur than current 2013-model OLED HDTV’s. 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. With strobed backlights, you don’t have backlight diffusion during scanning backlights. 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. For ultra-low persistence OLED’s, a rolling scan of about 1ms could be achieved, to produce ultra-low motion blur (useful for virtual reality applications as well). The Eizo “240Hz” monitor achieves 240Hz via a two-pass refresh. GPU power requirements would be lower, requiring only 60fps (or 72fps) for the perfectly-sharp CRT-like motion clarity, while avoiding objectionable overdrive artifacts. during a sudden frame rate speedup, the resulting further motion blur reduction would lag by 1 frame) which would not be noticeable.
