problems running GTA 5 on my 1366x768 LED Seiki TV on ps3.

When i launch GTA 5 my game runs in 480p SD it says also im on the ps3 if that helps i can run other games in 1080p it says. I dont know much about this kinda stuff some help would be nice. This is the TV i have. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6764194. If you need me to answer any other questions about the tv or the game just ask all feedback / help is needed! Thank you have a nice day.

You can't run games in 1080p because your display only has a resolution of 1366x768.
What might help is to go to your PS3 display settings and force the output to 720p always. (1280x720)

How do i force 720p?

Watch this tutorial:
At the screen (as shown in 3:20) only tick the box that says 720p

@depolarizeee: This is the kind of thing that happens when you buy a cheap tv instead of spending a little extra on a quality tv.

Whenever i just select 720p and i launch GTA 5 my screen goes blue and says no signal .. but yet i can play the last of us in 1080p doesnt make sense

If you think spending 350$ on a tv is cheap than i dont know what you're thinking

That is cheap man :S? my tv costs about 600 Dollar and it's a Samsung FULL HD with Smart function. it's only ok, had better but believe when i say that there's a reason why there are huge difference prices for a 40" smart tv from samsung. There are the cheaper versions and a lot more expensive versions from the same company with the same size. More vibrate color, better functionality, more ratio so much more stuff.
