Display With Horizontal White Bars - Larry Stehno - 07-19-2021
I just installed Linux Lite 5.4 on a HP Pro 3420 All-In-One PC. The install went well with a normal display but it has horizontal white bars running up and down over the display. I ran a update but no change. I checked for third party drivers and none were found thinking another video driver is needed. Any ideas for getting rid of these white bars? thanks,

We'll need to see a screenshot.

How do I send you a screen shot? JPGs aren't allowed for uploads.

Here is the shot of my screen with the bars from Imgur:

I've seen that condition with faulty cabling, can you try another cable or connection type (HDMI, VGA or DVI).

This is an All-In-One PC so there are no external video cable connections. This same problem shows up on two different PCs of the same model so it is unlikely to be a connection problem and is an inherent system problem with this model. What about the video driver? How do I either roll it back to an earlier version or find one developed for Linux? Thanks,

Experiment with your screen resolution. White bars are from mismatched horiz/vert combinations. When your find one that works then you can change it to stay preferred from the grub console.

I went through all the alternative resolutions and none fixed the problem. Thanks for the suggestion.
