Hey guys, I got my HTC Vive today. It needs an HDMI port and my monitor does as well. My GPU is an R9 390 with only one HDMI on the GPU. Although I have another HDMI cable on the motherboard I can't seem to get it to work. Any help? Thank you!
You would have to enable the onboard video, but the performance would suck.
If your screen is 1920 x 1200 @ 60hz or lower, you can use a DVI -> HDMI cable(or just DVI if your monitor has it). This will free up the HDMI port for your Vive
I am not sure about the Vive, but my friends Rift has to be activated to switch on(in his case only when a game or SteamVR is started.).
What did you end up with? DP to HDMI?
Can you try the DP to HDMI on your monitor to see if it works? The Vive has 90hz for a refresh rate and that may be more than a passive adapter can handle.
