Hi,
I am trying to use an old laptop (mecer xpression w550eu) with a cracked screen as a media center with openElec. Trying to set it up, I used a vga cable i found around the house to connect to my TV (Sinotec - not too sure on model) and there is a very strange and dramatic screen distortion. I then tested the cable with another laptop and it worked perfectly. So it cant be the tv or the cable itself.

I got the laptop from a friend and I dont know the specifics of how it broke, but there are obvious and prominent cracks on the screen.

Could the fact that the broken screen is still connected be the issue? I am not too sure how to proceed on this. Any advice would be appreciated.


I took a photo to show on my phone, apologies for the bad quality.

*Update - It seems the image stabilises when the laptop has been off for a period. It may be an issue with heat buildup possibly?
also when entering the bios, the distortions seem to be gone.

There has likely been a heat issue previously which has damaged the GPU or something on the motherboard. It may even be that if the cracked screen was due to a drop, the connections were compromised from the VGA output to the motherboard. Excessive heat can cause intermittent or stoppage of an electrical connection due to expansion of the metal used in the circuit.

The GPU itself could have even been damaged in the fall or if it's an integrated graphics solution on the CPU, it may be overheating.

Just to be sure it isn't driver related, you might try the solutions at the following link, paying particular attention to the CLEAN driver installation. Since the GPU doesn't do it in the BIOS, it may only be a driver issue. The rest of the...
