Like i said, i wasnt using my computer for almost 3 months as far i remember there was no line like that on my screen and this only can be view at black background any idea how to fix this ?
well actually its a laptop so i need an egpu board to use another gpu i suppose. i am already using a second monitor and it doesnt have a problem like this only laptop screen. i realised that only black color makes this line visible for exp. at full red or blue background i dont see any line like thisTry other monitor, if you have extra one.
Try connect the monitor into the iGPU, if your PC has onboard iGPU.
Try other GPU too, if you have.
