Hello, I can't enable 144hz after the 2 latest updates 5971 and 5972 (WHQL). If I use DDU to go back to 5768 (WHQL) i can use 144hz and have been using 144hz since I got my a750 mid February 2024.

Hello friend, sorry to hear that it's happening to others as well. Are you using an HDMI cable?

Do you know what DDU is? If not, then I can explain what it is or what it does. 

I would recommend searching for arc a750 drivers and downloading them through:

https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html

Updating has never been a problem for me using this method. But sometimes after an update, it won't stop searching for updates in Intel Arc Control. I usually use DDU after those to get a clean/problem free update.

Hello..! Yea I'm using an HDMI cable.
And should I use DDU for a update? but I tried uploading them by manually downloading still it didn't work.
And the refresh rate problem has been fixed automatically by restating and I am using 100hz.
Best wishes Rudra.

Hey, it depends on if you are having trouble with getting the update to install. If you can't get it to install, then it might be worth giving DDU a try.
