I have a 42" Phillips HDTV that I would like to hook my PC up to from time to time. How would I go about doing this?

I am guessing you need to hook your VGA connection into the VGA in on the back of the TV.

If it is HDMI, and you have DVI, buy a DVI to HDMI adapter.

You need a video card with s video or other output.An HDMI connection is better because you won't have to connect to the sound card also.Use clone or dualview in the nvidia control center.Ati has similar options in catalyst.

As I discovered, if your HDTV is the 16x9 variety (1366 x 768) your video card might not support it, altho 1024 x 768 comes close.

any modern video card will support a 16x9 resoultion... although you may have to create a custom resolution for it... but its not difficult.

I have the EVGA 8800 GTS 640 mb. My TV does have an hdmi hookup, so I should be good to go with the right connections.

yep. easy, just need a dvi (male) to hdmi (female) adapter. Then you just use your regular old hdmi cable to plug into the adapter, its 100% compatable (minus the sound of course, but you dont need it) this does work and is currently my bosses setup for his htpc.

Monoprice.com has some awesome prices on DVI-HDMI cables. I bought one and it works flawlessly. Its a 10' and I think it only cost me about $5-6. Compare at 5-10x that much at RadioShack. All of their video cables I've bought are good, but I'd stay away from their audio cables.

Won't he need to use both DVI connections to supply the picture?

The resolution for 16x9 is 1920x1080 and his 8800 hundred has no problem with that res and as state before he just needs one DVI to HDMI cable. His games or video will look great.

I'm been reading this thread and the others with interest!

I've recently brought a 52 inch Sharp 1080p LCD TV. Been downloading 720p/1080p films off (tsk tsk). Now I just need to work out how to hook up my PC to the TV

Currently I have a Geoforce 6800, with a single DVI output (powering my PC monitor) and S-video (which I hooked up to the TV).

Clearly this is sub-optimal, and I would like to upgrade to the Geforce 8800GT which has just been announced. I see it has two DVI outputs. So I just need a DVI>HDMI convertor or a cable with DVI on one end and HDMI on the other.

My question is, will I be able to have two signals as I do currently - 1900x1200 to my monitor though DVI1 output and 1080p output to the TV through the the DVI2 output?

If so this is great - does anyone know the answer for sure?

I just I should mention I have Windows XP, an A8N-SLI motherboard, Athlon 64 3000+ *1,8G real) processor and a gig of RAM.

I hope this should be enough to playback ok, currently I can play the 720 content on my PC and it looks fine but of course I would like a nice output on the TV :) On S-Video it looks crappy.

Use clone or dualview in the nvidia control panel.Dualview allows separate settings for resolution,color correction,refresh rate etc. for your TV.You will probably need the refresh rate set at 60hz for the TV though unless it will support a higher rate.

Cheers... same as now then....

The TV supports 120Hz so I hope the graphics card will too.

Are you saying your 6800 has only one DVI video output? I'd swear my old 6800 had two, or at least one DVI and one VGA.

 

VGA is way better than s video btw.....

Yep it only had one.

My new 8800GT has two, and my 1080p movies 52 inch TV looks stunning now :-)

Most HD content available for download (ripped off Blu-ray or HD-DVD) seems to be at 720p.... I wonder why this is?

A 1080p signal takes about twice the bandwidth of a 720p signal and would take about twice the space to store because it as about twice as many pixels. Bandwidth and storage space become an issue with a true 1080p quality movie. 720p still looks pretty darn good don't it?

1280 x 720 = 921,600 pixels per frame
1920 x 1080 = 2,073,600 pixels per frame
