Not sure if this is possible as I've seen products that send the video and audio from the PC to your TV but looking for something vice versa. What I'm going for is when my wife is watching TV and I want to play my 360 at the same time and since we only have one TV atm, but to be able to play it on my PC monitor via wireless of some sort. Anything like that out there or do I need to invent something? Thanks for any help in the matter.
A tv tuner card will do it. They all have the rca/coaxial plugs. You can get a cheap tuner card for 40.00. There are also external USB tuner cards available in case you don't have a pci slot. To have your 360 show up on the monitor you just choose aux/composite as your source instead of tuner. Finally there are also external tuner cards that bypass the computer and will hook directly to the monitor using the vga cable. Thats how I have all my computers setup (with internal pci cards, I use the msi tvanywhere plus model). They all do double duty as TV's, why waste a good monitor. I only own one "real" TV and it's not use much. All this is done through wires, even if you were to do it wireless you would still need to have the RCA/coaxial plugs (tuner card) on your computer or monitor to accept the incomming video/audio.
Thanks for the reply. Forgot to mention that my HDTV is in one room and my PC another. I want to send the audio and video from the HDMI source that my 360 is set to and send it to my PC so I can play my games on my PC while my 360 is on and my wife is watching TV all at the same time.
Most PC monitors have both DVI and VGA inputs. If the PC is using the VGA input, you can get a cheap converter that will change HDMI to DVI. If the PC is using DVI, you can get a cheap conveter to make it output VGA, thus freeing the DVI port. Unless your monitor has speakers in it, you will have to run seperate audio cable(s).
