Scotty, we need more compute power!

Machine from year 2015 with a built in browser? Or an old XP-powered Internet Explorer retro gaming system? Or old SmartTV browser? You can use TestUFO 1.0 at old.testufo.com It runs in many very ancient browsers.

TestUFO now has several dozens of different display motion tests! And more is about to launch with the upcoming TestUFO 2.2 including the long-awaited CRT Simulator.

720 Hz OLED FTW

Good afternoon Display Geeks at DisplayWeek! Mark Rejhon is at DisplayWeek and open for new business, or just to talk shop.

Deciding how to bust display motion blur? BFI? Strobing? CRT? Framegen? Organic? Etc? Users choose! William writes about blur busting methods including flicker-based (BFI, CRT, strobing) and flickerless (framerate-based, framegen-based, etc)

Want VRR in Google Chrome / Safari / FireFox? Newly simplified web browser VRR standardization proposal at WICG Proposals: github.com/WICG/proposa... Helps WebGL and WebGPU apps, and would help TestUFO too! If you're a web developer, comment!

Founder got surprised for his 51st birthday!

Happy 51st birthday, to founder Mark Rejhon, from the UFO Area 51 Laboratory!

Happy 404 Day. I just did the world's first HDR State-of-Web test. This is not even on caniuse site! More Info: github.com/blurbusters/...

Nintendo Switch 2 announced support for 120Hz and HDR. Including 120Hz Dock support. Now all major platforms (PC/Mac/Linux/iOS/Android + Switch/PS/XBOX) have 120Hz+HDR.

For HDR fans, good news: HDR is now supported by Safari Technology Preview Version 125. - AVIF HDR - JPEG XL HDR - WebGPU HDR (not WebGL or Canvas2D)

Parallels virtual machine for MacOS does not yet support HDR Windows gaming. Help vote to add HDR support: 1. Register for Parallels Forums: my.parallels.com/login?servic... 2. Read HDR thread: forum.parallels.com/threads/add-... 3. Vote for HDR support: forum.parallels.com/posts/888052...

Vint is now fully released! My temporal upscaling application supports advanced machine learning based interpolation, BFI strobing, and advanced CRT emulation based on the work of Blur Busters. Download it today at from itch io: willse.itch.io/vint or Steam: store.steampowered.com/app/3448910/

Did you know? Our famous TestUFO display tests now has a black levels / PLUGE test, too!

I'm happy to share that my temporal upscaling and interpolation app, Vint, now supports CRT beam scanning emulation based on @blurbusters.com/crt. CRT emulation allows any arbitrary video to strobed with less flicker than simple BFI. Vint is now on Steam: store.steampowered.com/app/3448910/...

Also, I'm willing to fund this "120 vs 480" more human visible than "60 vs 120" blind study (using mutually agreed scientific variables): blurbusters.com/120vs480#bli... (Scroll to Scientific Chapter)

Blur Busters Open Source Display Shaders Version 1.02 updated! - Added link to proposed Microsoft Display Shaders PowerToy - Added Security Considerations - Added use case: Accessibilitty - Added link to screenshot of new Valve GameScope email.

With recent successful introduction of blurless sample-and-hold (480Hz OLEDs), we're scrambling to give users additional choice of display motion blur reduction. - Strobe/BFI/CRT blur busting - Framerate-based blur busting BFI/CRT blurbust, framegen blurbust, non-framegen blurbust, & other methods

Instructions for Mac users of TestUFO with stutters. There's a new "High Power + High Precision" mode for MacBooks, via gear icon. Many TestUFO animations run as little as 0.1ms-0.2ms but stutters at 120fps 120Hz due to Mac power management. This very XCKD setting (#1172) fixes TestUFO stutters.

S.O.S. framegen S.O.S. Fake frames S.O.S. Fake frames But aren't polygons & textures faking real life too, even if framegen only 0.1% of 2010-era TV interpolation? Do we have alternatives for 4K 1000fps 1000Hz path traced photorealistic gfx? 120-vs-480 OLED is more human visible than 60-vs-120

Blur Busters Open Source Display Initiative Refresh Cycle Shader Specification v1.01 on website - Improved LCD overdrive! (on off-shelf LCD) - CRT shader - Plasma TV shader, DLP shader, etc - VRR simulator, LCD-VRR, even CRT-VRR - Adjustable GtG for OLEDs (better 24fps Netflix)

All your blurs are belong to us 👽🛸

Open source code is now released forthe world's most accurate looking CRT simulation. It lets you simulate the electron beam of a 60Hz CRT tube on your 240Hz+ display, in real time, and looks better than BFI. blurbusters.com/crt-simulati...

This is so important for the future of motion clarity. Just an unbelievable achievement that I’ve waited decades to see come to fruition. Amazing work here from Blur Busters.

CRT simulator GPU shader coming December 24, 2024 on github & shadertoy! Genesis of CRT-simulation replacements in future, when used CRT tubes are near-extinct. Tomorrow's 240Hz, 480Hz & 1000Hz OLEDs can optionally faithfully simulate CRT electron beam for 60fps content.

Comparison of 120Hz LCD and a 480Hz OLED. Rare massive upgrade feel that improves office productivity too, not just games!

Blur Busters Area 51! This is an old internal logo originally created for a discontinued pre-pandemic project. Thinking I should resurrect this logo as the logo of Blur Busters' current "Display Science, Research & Engineering" area. Thoughts?

60fps vs 120fps = 2x motion blur difference at GtG=0.00ms. Non-zero GtG pixel response adds blur, even if less than refreshtime. 1. 60fps vs 120fps weak on overdriveless mobile LCDs (~1.2x) 2. 60fps vs 120fps more visible on gaming LCDs (~1.5x) 3. 60fps vs 120fps very visible on OLEDs (~2.0x)

TestUFO's granddaddy from year 1994. Founder Mark Rejhon's MOTION.exe for MS-DOS, that compared multiple frame rates, just like TestUFOs' cover page. It was shared on BBS systems via FidoNet.

Have you busted any motion blurs today? Increase your frame rates? 👽

Even at zeroed GtG=0 pixel response, MPRT persistence is still nonzero! There are 2 main ways to shorten persistence (frame visibility time) to reduce display motion blur. 1. Add more black time between frames (black frame insertion, strobe backlight, etc) 2. Add more frames (higher Hz & fps) /2

VIDEOS! 📽️ Not all pixels refresh at same time on displays. LCD & OLED also refresh a few pixels at a time, in a raster top-to-bottom. With a GtG fade effect from 1 color to another. 960fps high speed video of custom test: (via TestUFO menu -> "Scanout") Slow Laptop LCD from year 2015: /7

Teaching Display Science 🧵 (First time on BlueSky) When panning/scrolling (e.g. map), you witness display motion blur when you try to read street name labels while panning. Scientifically, this is caused by display persistence (MPRT). At GtG=0, double Hz & framerate halves display motion blur. /1

PCMR may change, but the balance always remains. redd.it/1gy1lii

The sky is blue but the gaming rig is glowing red. Thinking what color my next CPU and GPU brands should be in year 2025. Maybe all of them? 🙂
