Question Horizontal lines on laptop screen ?

[Bakashe]

Hello,

Laptop model: MSI Katana 17 B13

I'm visiting another forum looking for help for my new laptop.

I see pixels, white horizontal lines mostly on blue/orange color, on facebook icons, windows wallpaper or in games looking at fire/sun. On white color or others you don't see them. Interestingly, I see them more at 144hz refresh rate enabled, at 60hz they are less visible. I was looking on the sites to see if anyone had a similar problem and came across this exact case:

This person managed to fix it with some "Asus smart Display hotfix 1.7.10" which he described at the very bottom of the thread.

Is there such a thing for Intel/Nvidia or my laptop? Maybe it's a driver?

I even tried to reinstall all the windows from new and these lines showed at the installation menu. (before all the drivers etc).

I did the external monitor check with hdmi cable, and I don't see the lines on second monitor.

It's damaged?

Here, as you can see on deep blue there are no white lines(pixels), but on the light blue (from the left, it's like white/blue/white/blue lines)

First 3 orange colors have the white lines between the color, also blue. Red is ok.

possibility: something to do with how the display 'displays' colors. to start with, you didn't see the white lines in dark blue, rather lines in light blue. because the display has 3 colors to work with, and it balances those colors to give the whole spectrum of light. it could be that the way those pixels are arranged, there should be a blank white line of pixels in order to reproduce the color light blue. eg: let's take the pixels to be arranged in this order. rgb/rgb/rgb/rgb... and so on(nowadays, this order is way different, and has bigger blue pixels cause the eye is least sensitive to blue light). and in the bottom line as well its the same order. I assume your display shows the light blue, by first displaying the color blue on one line and the next line to be a shade of white, to give out the color light blue when those are viewed from a distance. this might be the case for other light colors as well, as white is needed to make them appear lighter, this effect is seen.
while this may be unnoticeable on other colors, you can see a bit of this effect on them too, but them having horizontal and vertical lines which are kind of visible too.
also your display seems to be having a less PPI (pixels per inch) because when looking at that text in the above, you can clearly see some pixelation going on, so based on these 2 facts, I assume this is the case.

but hey, that's just one theory, and this seems to be violated by the fact that one person seems to have 'fixed it'. all I can say is, it doesn't seem like the screen has any hardware issues, rather a hardware limitation. feel free to correct me if I'm wrong, anyone. 🙂
