Horizontal Dithering on screen.

[LynnReese]

Problem... A horizontal band of multi-color, dithering (pixelating) has appeared in the lower half of the screen of a laptop. Below that band, any images and text flicker so as to render them unreadable.

I have updated all display adapter drivers for Intel. My LG Gram uses the Intel Iris(R) XE Graphics.

I have discovered that if I change the driver to from the Intel to the Microsoft Basic Display Adapter, the dithering and flickering goes away, but then I lose detecting/casting to other monitors on the network.

Any suggestions?  I've also reset my laptop completely, two times, and the problem is still there.

Thanks for any response.

Hi Lynnreese,

We are just following up.

It looks like you need more time to check with your system manufacturer since we have not heard from you. 

Should we not hear from you, our system may automatically close the thread.

As of this reply, my LG Gram laptop is functioning properly, in regards to its display. When the laptop starts up, the screen properly displays itself, with no dithering/banding/pixelating showing.

As to contacting LG, perhaps I'll do it at some point soon, but leave it to say LG has no support avenue that is conducive to straight answers from them.

I cannot express how impressed I am with the support I have received from Intel, and Alfred S. Intel stayed right in there, through numerous attempts and methodologies, until the issue was resolved. Intel has my vote for best of the best when it comes to looking out for the common man.

This issue is resolved. We may now close this thread.
