HD TV fried after connecting to pc help!

post #1 of 4
Thread Starter 
So.... at my girlfriends house they have a Polaroid TDX-02611C 720p HDTV. Weve used this tv in the past numberous times to connect my pc to when I bring it over. Lastnight was the same deal...accpet ive always noticed it will run in 1366x766 (dont quote me on the exact res) but the point is it wouldnt display in 720p. I have a Radeon HD 6850 card so my pc is more than capable of running in that format. I changed the res to that and the picture was burry and began to flash black faster and faster until the tv screen went blue and said no signal or something along those lines. Turned the tv off and then on again then I just ran it at the 1366x766 res and played swtor for about an hour. Then we swtiched to direct tv and watched a show for about 10 mins then the tv just turned off and it wont turn back on. I thought maybe it was overheating because the back of the tv was extremely hot but its the next morning and it still wont turn on. I want to know if I caused this by messing with the resolutions with my pc. Like I said ive never had this issue before but im worried I fried the family television to feed my mmo addiction. Any feedback or knowledge of this happening with HDTV's would be greatly appreciated.

You sure you weren't forcing a refresh rate that the TV couldn't support? If the TV died, it wasn't because it was connected to your computer. It died because it was on it's way out, or because you forced a resolution/refresh rate that it didn't like (but still somehow accepted it which usually isnt the case).

The fact the TV doesn't run exactly at 720p or 1080p means it's a cheapo. It's likely not designed for anything but native resolution or PC use. It is possible that having it set to a non-native resolution caused damage to it when you were messing with the resolutions. Normally, the TV would just say it can't display the picture, but i've seen cases where it just causes damage, though they are rare and almost always with cheaper TVs.

I never messed with the refesh rate ( ATI Control Center) set it to 57 and thats where it stayed. I Tried running the PC at 720p res and 1080p res but only for a few seconds for both because of the blurry picture. I can definantly see the tv conking out due to the resolution but weve done this before and its been fine. And this TV is only 2 years old.

1080p on a 720p?not advertised for it!mm 1080i probably wouldnt have affected it since it doesnt take a lot of ressource but 1080p is so dememding i dont know why 1080p isnt the otpion and the default isnt 1080i i have been running 1080i for month(properly set)and men it looks so good its insane,you will notice better quality on a 1080p one day?but sadly not at 1920x1080 @ 23 inch!you ll start to see difference around 40 +inch!yes some would say it aint so ,sadly they are mistaken ,they need to adjust their system properly!
