Windows 7: Integrated HD3200 & HDTV using vga. Is it possible?

Integrated HD3200 & HDTV using vga. Is it possible?

I've got HP tx2650er with integrated HD3200 (Catalyst 10.4). It doesn't have HDMI, so I tried to connect notebook to HDTV using vga output. But Catalyst identifies my TV as CRT Display with max resolution 1400x1050 (or smt.). There are 2 horizontal borders, just like when you try to output 4:3 video on widescreen TV. After i tried to force all possible resolutions in control panel, the screen just got purple (the borders didn't disappear). Tried to modify inf with PowerStrip - no result, screen became white. The TV is definitely HD. For test I successfully connected it to my main PC using vga (nvidia 8800gt) and there were no problems. Please, if you've found a decision, post it here. I've read amd forum (there were some similar problems), but nothing works. They said - it's windows seven problem (so that with vista there is no problem). So, connecting TV through vga is absolutely impossible for Catalyst? Need help, because i can't afford 10m HDMI cable (even if it exist) to connect to my main PC.
P.S. Sorry for my VERY bad English.
Method with changing driver also didn't work.

I don't think it will work with your laptop if it's autodetecting the TV at 1400 x 1050. It might not be reading the TV's resolution right, or it's a timing issue. Catalyst does have some HD modes, and it works with my PC, but not my laptop. The graphics card in the laptop just doesn't have the juice for it. I suspect that your notebook is the same way, at least from your VGA connector.

You can buy a 10 ft. HDMI cable for well under $50 here in Canada. It doesn't have to be "Premium Grade" or any of that. If it's 1.3 certified, it will work. There's no reason to buy top of the line cables because I guarantee you, from four feet away, your eyes can't tell, and if it's 1.3 certified, it passes all of the required bandwidth anyway. If you're going beyond 10 ft, pay a little extra for one's with good shielding to cut down on potential interference problems, but otherwise, save your money.
