Hi, I have an acer nitro an515-45 laptop with a ryzen 7 5800h/radeon rx vega 8 , nvidia rtx 3070, 40gb ram, m.2 ssd etc
I upgraded the panel from a 1920 144hz to a 4k 120 hz but it has strange flicker issues at 120hz. It works ok at 60hz but on startup it will flicker/ghost until the refresh rate is changed & changed back to 60hz, then it stabilises.
My assumption was that it was the rx vega 8 causing this as the rtx 3070 can display up to 8k res...but is it possible its a cable bandwith issue? Really hoping there's something i've overlooked as i'm only semi-literate with graphics tweaking. I've been unable to find a way to force the laptop to only use the nvidia gpu - disabling the vega just forces win 11 to revert to generic drivers which are worse..
I have all the latest drivers installed - used DDU on both gpus when updating.
Any advice would be greatly appreciated!
