I rent a room out to a friend who has a Viewsonic Elite, but it's the 144hz 2k one, not the 1080p blur-busters approved one and I can say, while it is nice, it doesn't come near CRT levels of motion clarity
Welcome to this thread!
I’ll have some more questions later, but wanted to introduce CRT-topics info:
CRT users can read Area 51 at
www.blurbusters.com/area51 to find the rare 1% LCDs that canget closer to CRT, if a use case makes a lighter/smaller/bigger display required than a beautiful FW900.
Refresh rate headroom is required to zero out double image ghosting on strobed LCDs, I recommend a 240 Hz panel for mostly double-image-free 120Hz strobing. 50% headroom makes it easier to cram LCD GtG into the VBI (blanking interval), refreshing 120Hz refresh cycles in 1/240sec, leaving a 4ms VBI to hide most of 1ms GtG from human eyes in total darkness between strobe flashes.
My first question: Have any bug-time CRT fans here yet tested the LCD motion resolution gold standard (Quest 2 VR LCD) yet, and compared to CRT?
Have you tried an Oculus Quest 2 VR headset yet, the most CRT-resolution-matching LCD currently invented to date? True real world measured 0.3ms MPRT and a near 100% perfect hide of GtG with a perfect ghost-free status (no double images, blur trails, or ghost trails, even for top/center/bottom edges). Not yet locally dimmed so grey blacks, but better motion clarity than most CRTs unlike most LCDs. Even some people here wear Quest 2 to view an IMAX sized 60 Hz CRT simulation watching 60 fps YouTube videos.
Be noted the two pixel response benchmarks, GtG and MPRT, are different (
See FAQ)

This info is supplemental for CRT lovers trying to figure out which of 10,000+ different panels of backwater dregs of LCDs to purchase, that may get closer to a few (even if not all) specific attributes of CRT.
In my experience, less than 0.1% to 1% of LCDs currently on market as of 2020-2021 can beat CRT motion resolution of an average CRT without visible artifacts — once configured to a cherrypicked mode (with refresh rate headroom), while strobed in a low persistence mode, combined with unusually superlatively perfect overdrive lookup table (LUT) tuning, etc. For the rare (for LCD) perfect zero-trailing-ghost and zero-double-image motion clarity.
Even all the plasma-motion-resplution-beating Blur Busters Approved strobe backlit panels has difficulty reaching an Oculus Quest 2 VR headset in Oculus’ big-money LCD motion clarity work.
Except, perhaps, when using humongous 0.75/60sec = 13 millisecond VBI (60 Hz mode with a VSYNC 3x larger than visible resolution!) to hide LCD GtG fully from human eyes (4x refresh rate headroom scanning 60Hz refresh cycles in 1/240sec, via a giant Vertical Total 4500 in video signal). Then the ViewSonic XG2431 VT4500 60Hz single strobe mode manages to go completely crosstalk free top/center/bottom like a Quest 2, after calibration with the upcoming ViewSonic Strobe Utility (
screenshot at bottom of press release). Most strobed LCDs tend to at least have superfaint crosstalk due to LCD GtG incomplete in dark cycle between strobes. Not an out-of-box experience but very hard to factory-include due to minor LCD panel variances (temperature, lottery) so the Utility self calibration is useful to zero-out the double image ghosts.
Now if you want resolution flexibility AND blacks AND color AND motion clarity.... We still have to keep waiting. CRT, baby.
All current LCDs beating CRT in motion clarity (perfect zero ghost like Quest 2) all currently have poor blacks.
Still waiting for 100,000-LED MicroLED FALD local dimming backlights utilizing wide gamut Nanosys Quantum Dots for CRT color and CRT blacks, without giving up the strobe. Most FALD backlights and wide-gamut panels don’t strobe as flawlessly zero-ghost yet.
OLED and direct view MicroLED are also contenders, but they are more costly than even Apple’s brand new impressive 2560-zone locally dimmed iPad Pro (bigger model) that has better contrast, blacks and color than many average models of CRTs. Fawn, fawn. BUT.... poorer motion resolution than ALL of the CRTs. If only that baby had the superlative strobe tuning of an Oculus Quest 2. Boo!
I view thousands of LCDs so I can say this — from a fellow “viewed tons of CRTs” to “viewed tons of LCDs”. CRT still wins big in the “I must have good colors, blacks AND motion resolution” combo. LCD is still only a line-item CRT beater (and only recently, and only for cherrypicked panels, at right Hz-headroom settings).
I started Blur Busters ten years ago because many disbelieved LCD could ever match or beat CRT in motion resolution, and I knew there were ways. Achievement Unlocked!
However, still a long way for jack-of-all-trades.
But jack-of-all-trades, all blacks/colors/motion line items simultaneously, like a CRT?
If only we could marry:
...iPad MiniLED backlight (+colors, +blacks)
...Throw in more zones to make bloom much smaller than bloom around CRT electron beam dot (preferably 100,000 zone local dimming backlight, still cheaper to build than an 24-million-LED MicroLED direct view)
...And with the Quest 2 better-than-CRT motion handling (+motion).
Merge the champs.
In time, in time!
So close, but no cigar for LCD. Yet....!
