  1. Fantastic stuff. Founder of Blur Busters here. All 240 Hz mythbusting is super welcome in the refresh rate race to future retina refresh rates! The Slo Mo Guys should do some high speed video of refresh cycles in real time. There's the TestUFO test, as well as the article with IPS + TN + OLED High Speed Video Comparision High Speed Video of IPS LCD High Speed Video of TN LCD High Speed Video of OLED More high speed videos can be found at www.blurbusters.com/scanout
  2. I recently investigated this quandry -- and as it turns out -- there's already an industry standard method that the manufacturers are using -- and found out the reasons why it's sometime inaccurate/subjective. What the manufacturers are doing is the VESA method, which only measures from 10% to 90% GtG. (Credit: scientific paper) This actually misses a lot of the GtG from 0% to 100%. But this was necessary in the past because electronic equipment needed to have automatic cutoff points to stop measuring. In many old screens, GtG never quite
  3. Chief Blur Buster here. Consider other important monitor features of a high-Hz monitor. -- Are you sensitive to stutters or tearing? Consider variable refresh rate tech, such as G-SYNC or FreeSync. Note: If you have an NVIDIA GPU, you may favour G-SYNC. If you have an AMD GPU, you may favour FreeSync. Unless you're getting a new GPU anyway. G-SYNC and FreeSync is very forgiving of low and fluctuating frame rates, and will fix a lot of stutters/tearing but won't fix motion blur. -- Are you sensitive to motion blur? And want CRT motion clarity?
  4. Linus, if BENQ sends you a Z-series monitor, make sure it supports V2 firmware (BENQ announcement of V2 firmware). There were BENQ Blur Reduction artifacts with V1 firmware for BENQ Blur Reduction. Only the V2 firmware can allow BENQ Blur Reduction to turn from "worse than LightBoost" into "better than LightBoost" via adjustment from third party utilities such as Blur Busters Strobe Utility. (This app can make BENQ Blur Reduction better than LightBoost, on average, if adjusted properly).
  5. It makes strobe-free CRT motion clarity possible. e.g. CRT clarity without the CRT flicker. 1ms persistence translates to 1ms of motion blur during 1000 pixels/second (e.g. panning/strafing/turning). Frames are static, while eyes are continuously moving. As you track moving objects on a screen, your eyes are in a different position at the beginning of a visible refresh, than at the end of a visible refresh. That creates motion blur as the static frame gets smeared across your retinas. The shorter the persistence, the less motion blur, as persistence-based motion blur is like a camera shu
  6. Wow, thanks for the mention of Blur Busters! (I've now posted this video on Blur Busters) I have not mentioned this publicly until now: Palmer Luckey gained exclusive access to a pre-beta version of TestUFO motion tests more than 1 year ago, long before it launched! This was long before Oculus snagged John Carmack as CEO. I'm one of the parties that convinced Oculus to eventually go down the "low-persistence" path during December 2012 / January 2013 conversations. Mark Rejhon (aka Chief Blur Buster)
  7. G-SYNC locks your framerate to the refresh rate of the monitor. What's different is that the refresh rate isn't locked anymore
  8. Sent reply. Blur Busters was a hobby (unfunded originally, now paid only a bit in advertising fees), and focussed a lot on the technology aspects rather than the gaming aspects. There will slowly be more and more gaming coverage on Blur Busters, but remember Blur Busters started as an electronics hobby (scanningbacklight.com) for my Arduino scanning backlight project before LightBoost was discovered. Yes, my unfunded, unpaid electronics hobbyist site (Arduino Scanning Backlight) slowly became commercial (renamed to Blur Busters), covered by Amazon advertising, so I do have to slowly withd
  9. It should, with this command line: mame -throttle -nosyncrefresh -nowaitvsync -notriplebuffer (That's a friendly tip for you, Linus ) Tech Note for emulator programmers: you just need Direct3D with the D3DPRESENT_INTERVAL_IMMEDIATE for the best, low-lag, G-SYNC synchronized emulator performance, calling Direct3D Present() executes immediate monitor refresh (if you just only need to blit an emulated frame buffer to a Direct3D frame buffer); Technically, the monitor no longer has a concept of a refresh rate; it's waiting for the GPU now. The programmer now controls the timing of the moni
  10. For those wondering about G-SYNC's ability to do stutter-free variable frame rates, there's a good animation of G-SYNC behavior on the TestUFO animations site. (Do make sure you run a stutter-free VSYNC-supported web browser, for an accurate simulation!)
  11. In addition to several overclockable IPS 120Hz panels, don't forget there's also 120Hz VA monitors now -- the two models by Eizo, including the consumer FG2421 (from 120Hz monitor list). The "Z" series BENQ monitors include an official strobe backlight (for CRT-quality motion on LCD) that's easily enabled via a monitor button. So you don't need a utility to activate LightBoost. All IPS monitors become very blurry during motion -- www.testufo.com/photo -- you only get crystal clarity on CRT, plasma, LightBoost, Turbo240, and BENQ Blur Reduction. And some of these new strobe backlights d
  12. It's very important to note that there's many different developments that makes things interesting for 60Hz vs 120Hz vs 144hz: - Strobe backlights allow LCD's to have the motion clarity of a CRT. They include LightBoost, Turbo240, BENQ Blur Reduction (XL2720Z), etc. - Strobed 100Hz and 120Hz has less motion blur than non-strobed 144Hz. - There's also non-TN 120Hz now available (EIZO's 120Hz VA panel, and Overlord/QNIX/etc 120Hz IPS) - Overclocked monitors (e.g. IPS 1440p), more resolution and better colors, but much more motion blur There's a big list of 120Hz monitors that lists a
  13. 1. Have you ever tried LightBoost? (Or google "lightboost"). LightBoost has far less motion blur than 144Hz. It is a strobe backlight that eliminates motion blur, by turning off the backlight between refreshes, and flashing on fully refreshed frames. So it does flicker like a 120Hz CRT, somewhat darker, but motion blur becomes gone, and fast panning/strafing/turning has no motion blur (and motion tests such as www.testufo.com/photo no longer has motion blur). Today, LightBoost is easily turned ON/OFF via a keypress. 2. For testing the 60Hz experience before sidegrading to better co
  14. A great way to figure out why it's is not feasiable without hardware modifications: 1. Watch high speed videos of traditional display refreshing: - - - 2. Observe all the above refresh at an exact interval (synchronous), refreshing like a clock, tick-tock, exact schedule. That's the way displays have functioned for more than 75 years, since the invention of the first televisions. Synchronous refreshing. 3. G-SYNC eliminates the exact schedule of a display refresh. A display can refresh at random moments. e.g. one refresh, then another refresh 7.689 milliseconds l
