My TV keeps losing signal from my pc
So basically I have a Samsung LED TV model code: UE28F4000 and I just recently bought a PC running windows 7. I connected the PC to the tv using and hdmi cable which has never had any problems before when i used it on my xbox but for some reason my tv loses signal for about 3 seconds and then coming back on.Its really starting to get annoying. Even if im just on the desktop it will still do it.

Does anybody know if theres a fix for this? I dont think i will be able to use vga because my secong monitor is already using that

Come on guys. Google it? native resolution is 1366x768. Its a 720p 50Hz TV.

You can try the 720p50 mode. Or try another monitor to see if it is the laptops output

Does the PC have onboard video or a dedicated GPU?

Okay, so 1280x720 doesn't look right?

Do you have the same problem with all resolutions you set?


Yeah it looks terrible. Same with all the others. I don't know if the problem is going to happen on a different resolution but all the other resolutions dont seem to work for my tv. Either too big or too small.

I did see an option in the amd ccc to force '720p50' (pal) to the display manager but it said it could cause my tv not to work anymore, I dont know if this could work but i dont really feel like risking it until i know what it is exactly

Is your TV's native resolution 1080p? If so, change your desktop resolution to 1920x1080 and test out if it still does it.


I'm pretty sure my tv's native resolution is 720p, when i tried 1080p everything was too small and didnt look right. The only resolution that looks right is 1366 x 768 :/

How about testing another cable?

What is your resolution on the PC set to? Is your GPU set to 60hz?


I've tried a few cables and they all do the same thing. My PC resolution is set to 1366 x 768 (28" TV).

I'm not too sure how do I check? I have amd catalyst control centre is that helps
