Quick HDMI question!!!

My dad has back problems which make sitting at a normal computer troublesome for him. His vision is also not that great. He does however have a pc and a large plasma screen. I'm pretty sure there is a cost effective way to get the output from the pc onto the screen. There is an HDMI (type a, 19-pin) input on the back of the screen, and you can get a video card with HDMI output for less than $30. I can't help but wonder though, is it as simple as installing the video card and getting a long enough cable, then just plugging them in? Also, are there still issues with plasma and still images? I don't know the manufacture date of his screen, but it's probably around 2-3 years old. Here is what he has, and the video card I'm looking at. Can someone see anything that tells them this will NOT work like it appears on the surface that it will? Thanks in advance.

Screen: Panasonic TH50PX50U <http://reviews.cnet.com/flat-panel-tvs/panasonic-th-50px50u/4507-6482_7-31349718.html?tag=mncol;rnav>

Awesome. Yeah, the wireless gear is definitely in the works for that. Now they just need to add the new video card, and continue to use the existing card to display the screen in the office (where the pc is located), and send the new card's output to the hdmi out. Is there any way to send the hdmi video signal wirelessly to the Panasonic? That would be "player edition", and just to double check, do plasmas still have burn in problems or are they past that now?

there is wireless hdmi but its expensive. and i have no idea how well it works. but here's one i found on a quick search.

i cant answer the plasma burnin question as its been several years since i've dealt with one. i'd check out some av forums and ask there.

The Radeon 3450 should have come with a DVI to HDMI adapter. If it didn't you should be able to get one from new egg along with a 6ft HDMI cable. You could also use a component output, but then you will also need to buy an adapter to connect the stereo output with the corresponding audio input. Panasonic makes the best Plasmas, but since that is an older model I don't think it has the pixel shifter technologies. While Panasonic has done alot to reduce burn in the pixle shifter technology is an extra step that shifts static pixels in a patern to further reduce burn in.
