I wanted to hook my new rig up to my 42inch plasma but I am not exactly sure how to do this.
I have a Radeon HD 4870X2 so I know it comes with both video and audio HDMI support and I know my plasma displays in only 1080i but it is my understanding that this would be better than my moniter that only goes up to 1680x1050.
Besides not knowing what cable to hook up to what jack or where everything is located, I also wanted to know if a hdmi connection would be better than like a vga or dvi connection cuz I could do that also.
Also my tv is hooked on the wall so the actual hdmi cable is in the wall and I wanted to, if at all possible, not have to pull the cable through.

1080i is 1920X1200 res so yes it is higher res than your monitor.

HDMI is better than DVI or VGA as you can also transmit sound thru these cables and I think it probably has better picture quality. So use an HDMI cable along with the converter you probably got with the card when you bought it.

1080i is actually 1920*1080 :D

hdmi would be the best choice, you'll get the sound as well.
dvi or dvi-to-hdmi would be the second best alternative, you'll lose the sound but the picture quality is still great.
old style vga gonnection is the worst, it's analog connection and the picture quality is rather poor for such a big lcd.

Just because it says it supports 1080i doesnt mean its highest resolution is 1920 x 1080. A lot of the cheaper plasmas have a native resolution of 1366 x 768 which if it will scale to 1920 x 1080 is going to look like cr*p. Not to mention 1080i will max out at 30 hz which really looks like cr*p when hooked to a pc.

My 4870 came with a dvi to hdmi converter. If you have one all you need is the hdmi cable. You can hook up sound to the vid card and it will send it to the tv through the hdmi cable but I dont know how its done.

crobob is right, interlacing refreshes every other line each frame, therefore it only requires a total of 540 vertical line to display properly. Most 42" plasmas have a resolution of 1366x768 or 1024x768 (ewww non-square pixels). Some have 1080p resolution (1920x1080) like the Panasonic PZ series (TH-42PZxx or TH-42PZxxx).

I'd bet money your TV has a resolution of 768 vertical lines.

HDMI is the best option.

Is there anything inherently different about hooking up a plasma to a computer rather than an LCD HDTV?

Sorry to hijack but....... :D

Crap, I think you just explained a problem I have. My laptop's display on my TV is too large. It cuts off all edges of the image.

Is there a program I can get to shrink the image on my TV?
