Last test for today. I have updated the driver changing how some component inside the gfx chip works. Please test.
Most probably this could work good at 1920x1080.

@sonountaleban Probably some more code need to be implemented for your cpu/gpu, and without your log (you go to holidays if i remember correctly) i can't be able to check if what we change is correct, i'd say we could continue when you return, unless someone else with a similar hardware came out.
Thanks anyway for your help.

Well, until tomorrow I'll stay here, so I can do some further tests...

@sonountaleban
OK but you need to find some USB pendrive for proper tests, and also you need to tell me if you use a TV for display. It's important because i need to program properly the chips for driving the panel of your laptop, if you use a TV it's not the same.

OK thanks but i need the log to be examined for making proper fixing.

Do you need the out.log files for each resolution, or do they accumulate?
I'm attaching the out.log file that was left on the USB drive; it's larger than usual, so I'm not sure if there are more logs.

Accumulated is perfect so you can change every resolution without saving more than one log. I do like this multiple change of resolutions all in one log file.
Thanks

With those limited info from log (that only lists working resolutions) we produced a new driver attached.

In order to know how to fix, i need the artifact captured into the log. Please boot to 1024x768 and try to reproduce the artifact. Take a picture and Power off the machine. This saves a log with the artifact.
Next reboot and instead try to select other non working resolutions all in one log if possible, if not try to save the logs for a couple or more resolutions.

Thanks.

Sorry, that was a copy-and-paste error—1024x768 works very well; the artifacts and screen clipping only occur at 800x600 and 640x480.
