Hey all

I know these are the threads for monitors, but I couldn't find one for laptops specifically, and since this is a display issue I posted it here.

A customer brought in an older 2 core HP Pavilion laptop for service a few weeks back. It was riddled with malware, and since they wanted it set up for a second computer I decided it would be faster to just reinstall Vista on it.

I reinstalled from the recovery partition on the computer, containing an exact HP image specifically for this computer.

During the re-installation, I noticed that the display seemed to stretch off the bottom of the screen. I wasn't too concerned because I thought it would correct itself when it installed the GPU and monitor drivers.

The system completed the install and it seemed fine, but after rebooting because of some (many) Windows Vista updates, it booted up with the wrong resolution again. It sets the display to 1680 x 1050, but it's supposed to be 1440 x 900 (even the aspect ratio is wrong).

If I go into the display settings, the slider does not have an option for 1440 x 900. I checked the monitor driver, and it's set to "Generic P&P Monitor". I thought this might be an issue, so I checked on HP's site but there is no display (monitor) driver for this computer (Sorry, I don't remember the model number, but I can get it later if we need it). Of course, if there was such a driver it should have been on the recovery image.

I tried deleting (uninstalling) the monitor driver and rebooting, but still got the same problem. I searched all over the 'net, but there was nothing on this fault other than "update the video driver" and "update the monitor driver", neither of which works to solve the problem.

Finally, I did a search for HP LCD monitors that display 1440 x 900 (most 19" monitors). I installed that driver on the computer and forced it to use it instead of the generic driver. Surprise surprise, it worked! I was able to select 1440 x 900 and everything was fine.

Fast forward to a few weeks later. Customer installed iTunes, and tried syncing their device. Something happened and the computer went back to 1680 x 1050 again. Only this time, it was still using the 19" HP monitor driver. Go figure.

I was going to get the customer to delete it and reinstall it again over the phone, but when she deleted it and rebooted, the display came up correctly.

I don't trust that it will stay this way, so I thought I would post a message here asking if anyone has ever had a similar issue, and if so how they corrected it? I know the display should pass along EDID data to the computer and that should set the resolution. However, we're talking about a laptop, and the screen is just an LCD panel, not an entire monitor.

Perhaps a firmware update is in order? I would have done this already, but since I couldn't find any information on this fault, I didn't think it would be a part of the solution. It seems that literally this is the only HP Pavilion laptop that has ever had this problem considering I couldn't find anything on the 'net about it. As I mentioned, I did find issues regarding connecting external monitors, but this fault is with the internal display.

So, in case the customer calls again with the same issue, I was wondering if anyone has any further info on this type of problem, or any suggestions on what may be causing it? The customer did mention that the problem was an issue before they brought the computer to us, so (thankfully) it's not something we caused.

I was thinking about the cable that connects the display to the motherboard, which is a very common fault on HP laptops, but since there are no other symptoms I don't think that's the cause (although I wouldn't rule it out).

Any ideas would be appreciated.
