Hey all, I've been reading this topic with great interest after having owned an IIyama GB3466WQSU for a short time.
I had my hopes this model would work flawlessly, but I understand many are having Freesync issues too.
I wouldn't pay to much attention on the removal of the g-sync compatibility label though. One of the criteria to pass Nividia's certification is quite laughable.. saying the monitor has to enable Freesync with default settings.
Which in practice means an auto fail for the majority of screens. Hooray for g-sync right
.
Unfortunatly it's really hard to find the source of the flickering problems. Videocard drivers and games themselves are big factors for sure.
I had an 5700XT on loan with the IIyama and Freesync worked fine for the bigger part.
Only in game menu's, loading screens and a few older games would show flickering.
Combined with a 1080Ti on the other hand gave nothing but trouble.
At the moment i'm trying to figure out which scalers are used in each screen. The IIyama has an MStar one and the AOC uses a Realtek one as far as I could gather.
Is there an owner who is able & willing to acces the service menu or use softMCCS to determine what brand and/or type is used on the Gigabyte G34WQC?
My assumption is the issues are more related to the scaler then the actual screen itself, since many other 16:9 144Hz VA's screens work without any issue.
