Lost 120Hz on BenQ XL2420Z
Posted: 15 Dec 2016, 22:44
I tried flashing an XL2420Z V1 to V4 with the linux method.
Everything seemed to go fine, no error messages, found the correct bus and chip etc.
But after flashing, during it's verify phase, I got a message that it failed at address 0x00000000 already. Not daring to powercycle, I tried flashing again, this time it all went through. I was away from my screen for a couple of seconds so it seemed though that the actual flashing/writing only lasted a couple of seconds instead of the minutes it took the first time.
I didn't think much of it though as my monitor was flashing colors and showing a message about burn in that I didn't recognise.
So I fiddled with the monitor a bit. Trying to turn it off and on, trying to see if I could get to the information page to see if the flash succeeded and lo and behold V4 was installed.
Reboot back to windows 10.
Now I find that I have 60Hz, 100Hz and 144Hz resolutions available in my Geforce settings. My 120Hz resolutions seem to be missing.
I enter a new custom resolution, forced to 120Hz and the vertical total to 1350 because that's supposed to make my screen a bit brighter as well.
This seems to work slightly. Dark colors are still way too dark using the calibrated icc profiles you can find online.
When I turn on blur reduction in this resolution, the screen turns black. So I can't use that.
If I enter a custom 120Hz resolution without changing the timings, it does seem to work with blur reduction. Only the monitor itself now reports that it's doing 60Hz instead of 120Hz.
Did I mess up my EDID?
I unfortunately don't have a backup. My harddrives were inaccessible from the linux side of things and I gave up trying to get my phone recognised as USB storage after the flash seemed to be fine.
Can I just retry flashing V4 or do I need to reinstall the nvidia drivers perhaps?
Is there a V5 for XL2420Z that might fix things? I heard mention of it, but can't find it anywhere. V4 is the only one I can find for that matter. The BenQ gaming download site takes you to the Zoey page now instead of letting you download any firmware. V2 can't be found anymore so I can't try that either.
I'm also still unclear about that burn-in option. I know now how I can reach the settings page to change it with holding down the 3rd and 4th button simultaneously while tapping power, then using the 5th button to show the burn-in setting. But I got no clue what that does except for changing the color of my power light to orange.
Should I flash with burn-in enabled, would that fix things?
I'm a little worried of messing things up more, so I'm asking here.
