try using the display driver uninstaller here Display Driver Uninstaller Download version 18.0.2.3
Then reset your monitor to defaults using its on panel menu. Then power cycle your monitor and restart
your pc and install new drivers buy re downloading them to avoid corruption.
make sure you have your monitor's driver installed. You can download it from here: EX3203R Software - Support | BenQ USA
From Benq's Resolution file:
I have attached Benq's Resolution file to this reply for you to download if interested.
Yep, has been installed since I got it.
You didn't say how you are connecting and what your OS is.
Sorry, this is on Windows 10 (version 1903) with a 1.4 displayport cable connected
Need to update your Windows version to 1909 since the latest AMD drivers work best if Windows fully updated via Windows update.
Your monitor does not support 144Hz while being on 10bit. Switch to 8bit and you should be able to get 144Hz
So this didn't seem to work. I dropped it to 8 bit with dithering from the Monitor tab in the Radeon driver software (and rebooted) and still max hz was 120. Also tried a full uninstall using the AMD Software remover and did a clean install of the 4.1 drivers and oddly enough it changed the monitor to 10 bit again which is odd because I'm pretty sure its a 8 bit panel according to BenQ
Send the exact same screenshot you provided in your initial post showing 8bit
Seems locked at 60hz now. Now other otpions.
Please file a support ticket
So I figured out the issue. It seems the Monitor has 2 modes. FreeSync Normal and FreeSync Premium. It was set to Premium which caps the refresh rate at 120hz but ups the quality to 10 bit. I changed it to normal and it went back to 144hz. Thanks for everyone's suggestions.
