My laptop was running ubuntu, and one day it decided to change the screen orientation to 4:3 instead of 16:9, and drop the resolution to 1024 x 768. It is also shifted to the left side of the dislplay as opposed to being centered. there is a 4 inch black spot on the right hand side. Also this is not simply in ubuntu, (which in an attempt to fix the issue, I've completely formatted) it starts on the boot. from the bios. I am currently running a live boot from a jump drive just to surf the web, and I have a copy of windows 7 i want to put on it. But only if i am able to get this fixed.

Thanks.

Have you gone into the BIOS setup and looked for an option to choose between 4:3 and 16:9 modes? It's also possible it could be set with a key combination - what brand and model of laptop is it?

A bump is fine. I was always willing to help if I can, but for some reason this topic didn't show up in my list as being one I hadn't checked since the last post.

The documentation I can find on Dell support doesn't give a full run-down on all the available BIOS options, so I can't be sure if there is any option in there to change the hardware video aspect ratio. <Fn><F8> seems to be the key combination that cycles through the video options, but they don't comprehensively list them all.

The fact that this occurs from the POST screen indicates it's a hardware issue, either a setting or a fault. Is the display the same within the BIOS setup screen? Do you know if the laptop will switch the display to an external monitor from the BIOS setup, to see whether it also displays the same?

It shows on the left side in the incorrect screen resolution at all times. i have not seen the right side light up. fn f8 just flashes the screen on and off for a moment. and while in the Bios, fn f8 puts it on the external monitor. fn f8 also puts it on the external while in windows. but the issue still persists. although i can alter the resolutions if i extend my display. (on the external. the laptop is still messed up)

If the keyboard shortcut simply cycles between laptop screen/external screen (common), then unless there's a specific setting in the BIOS to change the screen mode between 16:9 and 4:3 (maybe with centred/offset selection), then I'm not seeing any further option than a problem with the video chip.

Maybe someone else who is very familiar with Dell laptops can suggest something. I'll ask if any of the staff have further suggestions.
