For a long time, Windows-based multi-monitor was defective with mixed-Hz operation.
Simultaneously connecting a 144 Hz display and a 60 Hz to the same computer was long possible, but had a side effect: Major stutters and jerky motion occurred on one of the two monitors when both monitors were simultaneously displaying motion.
Gamers, Rejoice! Fix Arrives In Windows 10 Update 2004 20H1
Reddit user loopy750 posted on reddit, a demonstration of the fix, and gamer netizens have been hugely escastic, profusely thanking Microsoft on reddit and in comments/forums such as resetera.
Gargantuous if factual
Holy shit, finally. I just assumed it would never get fixed.
wow I was expecting for this for a long time
This Windows bug is not seen by office-environment users using identical DELL and HP monitors running at identical refresh rates.
However, many gamers, esports players. and the rest of the booming gaming industry, have become vocal complainers of this bug, so the collective relief is huge.
One Possible Caveat: Still Single WDM Compositor Thread
A source has informed us Microsoft fixed this by operating the WDM compositor at the highest monitor Hz. For the 60 Hz + 144 Hz multi-monitor situation, the fix will will still greatly improve motion by preventing 144 Hz monitors running at only 60 fps.
Instead of 60fps stutter (1/60sec = 16.7ms stutters), your stutters will be be much more minor, equivalent to 144fps played back at 60Hz (1/144sec = 6.9ms stutters). Minor stutters will still happen, but much better than before.
This won’t produce as smooth motion as having separate independent WDM compositor threads (one per monitor perfectly synchronized to its refresh rate). Microsoft should enable this, at least as a Performance Setting for a future version of windows, that only gets disabled in Power Saver Mode.
Windows Still Has a 512 Hz Refresh Rate Limit Despite Upcoming 1000 Hz
Unfortunately, Windows still has a 512 Hz refresh rate limitation.
Recently, NVIDIA and ASUS announced a 360 Hz monitor at CES 2020. We created a custom TestUFO test for NVIDIA specifically for the CES demo.
Also, ASUS now has a long-term road map to 1000 Hz gaming monitors as their representative confirmed to Blur Busters, to PC Magazine, and to several other sites.
At our meeting with Asus, a rep told me that 360Hz is just the beginning of what the company calls its “road to 1000Hz,
— Quote in PC Magazine about ASUS’ 1000 Hz road map
We have been the forefront of 1000 Hz advocacy, with articles such as The Amazing Journey To 1000Hz Displays and The Stroboscopic Effects Of Finite Refres Rate. It is necessary to go dramatically up the diminishing curve of returns to maintain human-visible benefits.
We appreciate the moves Microsoft is making to recognize the refresh rate race, but acknowledge more work needs to be done.
