Hello people, A couple of days ago I had to replace my laptop screen. First I got a wrong one (wrong resolution, didn't pay attention, rather stupid of me) but after sending it back I got the right one. After I installed it though, there was a flashing in the whole screen (just flashes of a fraction of a second.), especially when I was on battery. This I sort of fixed by messing around with some settings in the Intel Integrated Graphics control panel. (My laptop for some reason has two Graphics cards, I disabled the setting that switched the refresh rate from 60 Hz to 40Hz when on battery.) Unfortunately though, I still occasionally have a flashing in my screen. The flashes are only a fraction of a second, and aren't the screen turning black, but it looks like it displays the upper part of the screen at the lower part of the screen. (bit hard to explain, but picture just copying the upper part of the screen and pasting it at the lower part for a fraction of a second. I'm not sure if this is a hardware problem (Broken screen, or worse, cable.) or it has something to do with the graphics cards or software. Reinstalling the drivers for both graphics card didn't help. It's not a really major problem, but the flashing is driving me insane. Thanks in advance for any help.
