I recently bought a Samsung PN50A450 from Sears. It's a great television and I love it. The problem I am having is when it is connected to my gaming computer. It is connected by a DVI to HDMI cable. I can get the computer to work great on the tv and everything looks great.


The problem is if I turn the computer on before I turn the television on, or I turn the television off while the computer is on, I cannot get the television to turn back on. Does Anyone know why this is? Any help would be greatly appreciated.

I assume you're using an ATI card? Depending on the card, once it loses the DHCP connection, it fails to re-acquire it. If you check out www.thegreenbutton.com there are tons of people over there with the same problem. Not sure what to suggest. Maybe more info for starters. Which video card specifically are you using? Etc.


Edit: This post interests me, because I'm considering this TV (although they just RAISED prices on it) and it will be connected to a Vista Media Center computer with an ATI card in it.

Interesting. That's not even a DirectX 10 class card (which is where most of the problems seem to currently be, along with Vista). I had a 7800GTX that at one time suffered from the same problem you're currently having. It was connected to a Sanyo LCD. However, as I continually updated the drivers, the problem finally went away and it appeared as though NVidia had finally fixed the problem.


Are you running Windows XP or Vista? 32-bit or 64-bit? I assume you've got the latest drivers installed?

It's certainly not your video card, your card is capable of HD.


Are you connecting via VGA or DVI to HDMI?

It's not a problem, rather a "feature".


If you turn the TV on, and change the input to computer (PC in or HDMI) leave it for about a minute, the TV will be detected by the computer as available again.


Good luck.
