    HDMI / DVI - Occulus Rift Questions

    It will probably be a long time before I can afford this thing but it looks pretty exciting. Looking at it's setup made me wonder. Part of the setup requires a HDMI out or DVI output from your PC. Fair enough. But on my Nvidia 980ti GPU I already use the HDMI out to connect to my monitor. It's very hard to get round the back of my PC but from memory there is another DVI port and three other ports that I have no clue what they are (DP? They look like HDMI but slightly different shape). Anyway, I just wondered if the Rift can plug into the empty DVI and at the same time my monitor can remain connected to the HDMI output. If I had the Occulus Rift the last thing I'd want to do is have to go round the back of the PC everytime to unplug the HDMI that goes into the monitor and put the Rift into it's place or in the DVI port because the cannot be concurrently connected.

    Another thing that isn't clear to me, despite googling the FAQs and topics, is can Occulus Rift view older games or even the actual desktop? In other words, does the computer screen get replicated through the headset? Obviously I know it wouldn't be 3d or optimised but just wondered.

    I also wonder if the thing will demand the very latest GPU drivers. I still use Nvidia drivers from around September time as I really dislike updating them unless there is a compelling need to do so. I read enough horror stories on the Nvidia forums about their latest releases causing all manner of grief for some people. I like the 'if it ain't broker don't fix it approach' so leave them well alone.

    I don't own an Oculus Rift, or plan to buy one anytime soon.

    The additional outputs on your 980ti are indeed Displayport. I imagine that you could use a DP to HDMI adapter (passive, cheap) to support the Rift.

    I have no idea whether the device is set up to allow you to view the Windows Desktop. It is spec'd at 2160 X 1200 pixels, higher than your monitor. It's an OLED as well, so it sounds like it may give a rather pretty view. I doubt that I'd care to use it for non-gaming tasks: the 110 field of view would put the image (effectively) too close to my face. I'm also not a touch typist, so I'd want to glimpse the keyboard from time to time.

    Cheers, they were just speculative questions really. The FAQs across the net seem to be pretty generic. I'm not even sure if I'd buy one. I certainly wouldn't want to use the desktop with one on. But it was more if you were gaming on one then quickly quit the game and wanted to check something quickly and then go back in or do another rift game, that you could do it all without unplugging the rift or removing the headset. I guess as time goes by and more people use them these kinds of things will get explained better on the net
