Interesting. I'm guessing it's probably the same underlying hardware, but the F model is using a better binned panel from the manufacturer than the M one. If that's the case, I'd expect the margins of superiority between them to be somewhat variable with only the worst stat being guaranteed to be better on the F than the M models. (Because the worst stat is the one that'd pull it down into a lower quality bin.)
Regardless whether or not the variable backlight is enabled you're still dealing with an array of lights, so it could be that the one bank on that side of the monitor is having issues while the others are not. When the variable backlight is not in use the monitor just applies the same voltage across all the backlights for uniformity.
So far it appears swapping out the motherboard from MSI to Asus has resolved the issue with the monitor. Still testing but a few ways I had of guaranteeing a lock or BSOD (changing refresh rates in the nvidia control panel) no longer lock the machine. Also a particular game would take about 2 minutes to load with the monitor connected, this is no longer the case. I'll let you know if I get another blue screen.
Well that is good to know. I am kind of happy for you and kind of sad also about the news. I definitely won't be swapping the MB out. While I do have some issues it's not unusable for me. I haven't had a BSOD since my last posted one. Still I am running without the USB cable plugged in and at 120hz for my desktop. I still have the updated MSI bios to try. It's now out of beta and it has some fix for GPU re-bar support so maybe that'll fix it.
Fortunately I gained a lot more than just the monitor not crashing. As a part of the swap I changed out to a heat sink that covers the entire threadripper die bring my temps down considerable (from 90 in cpu-z stress test to 65). I can also now run my memory at 3600 whereas I was stuck with 2666 with the old MB. However, I am giddy that the monitor now works as so far the FI32U has been an awesome monitor.
RTNGS is testing now. There's kind of a dearth of good technical reviews - but the monitor is fantastic.
Been running with the monitor for 4 days and zero issues. There does appear to be an incompatibility issue between the FI32U monitor and the MSI Creator TRX40 motherboard.
Been messaging with gigabyte support and basically they can't believe the monitor is the cause, I told them I got the DPC_WATCHDOG_VIOLATION when the USB uplink port is connected and they are wanting me to test my CPU *sigh*. I keep telling them I basically don't have any issues since I disconnected the USB uplink port to motherboard cable but it's like those words are invisible to them lol.
This is a weird enough issue that unless you can shiboleet your way to an engineer somehow getting any sort of resolution will probably be impossible.
I played with a few but I'm back to Standard
Unfortunately not the case here
Surely this is a firmware issue. Gigabyte monitors have typically had great input lag
From the RTNGS report: 'it has slightly higher than usual input lag, especially when gaming at 60Hz'
Keep an eye out for the notX
Imagine if they knew the early LCD screens had 50+ms response times and people gamed on them... They'd need to be wheeled into the psych ward!
Not to mention they ran at 60 Hz and the game itself might not have run at 60 fps in any consistent manner.
