DisplayPort > HDMI converter doesn't work with Vive
The HDMI port on my graphics card went out, so now I am using the display port. I purchased a DP > HDMI cable because I need to switch between my TV and my Vive, and my TV is HDMI only.

Anyhow, the DP > HDMI cord itself works fine on both devices. I then received a DP > HDMI converter so I could use my HDMI cables between the Vive and TV. When I have the converter with an HDMI cable going to my TV, it works fine. However, using the converter and the same HDMI cable going to the Vive breakout box, I get no picture on the Vive (althought it detects and tracks fine).

Any idea why the DP > HDMI cable works fine, but the DP > HDMI converter to HDMI cable to Vive doesn't, but the same setup works fine for my HDMI TV? Is there something specific I should be looking for when purchasing a converter?

Thanks!

EDIT: This is the converter I'm using:

From the link you gave:

Note: This is a passive adapter. While DisplayPort connectors are capable of passing an HDMI® signal, DisplayPort and HDMI® signals are basically different and not compatible with each other. This adapter does not actively convert a DisplayPort signal into an HDMI® signal. In order for this adapter to function properly, you must have a DisplayPort source device capable of producing and passing out an HDMI® signal through the DisplayPort jack.

My 970 can pass an HDMI signal through DisplayPort. As I said, when I use the DisplayPort > HDMI adapter and plug it into my HDMI TV it works fine. For some reason, it doesn't work when I plug it into the Vive.

Assuming you have a Vive Pre your best bet is to get a display port to mini-display port cable and use that. The new interface boxes will take a display port cable directly.

you need an active adapter, I'm using this one with the Vive; Accell B086B-003B-2 UltraAV DisplayPort 1.1 to HDMI 1.4 Active Adapter

it's cheaper to just get a display port to mini display port cable however.

Wh- Why didn't you just buy a displayport to mini diplayport cable?
I've been running mine off one since the start...

As I stated in my first post, I only have 1 working output on my graphics card now, and it's DisplayPort. I use that same port for both my television (which is HDMI) and the Vive.

Thanks for the info on the active adapter, I'll give that a try.

I am in the exact same boat. I show one missing driver in device manager, it had "VID" all over the settings, so I assume that's the headset.

Anyone get this to work? Purchased a DP > HDMI to power the Vive headset. Shows green but never lights the screen up.

I went through 3 different DP > HDMI converters, and the exact same thing happened to me. I only got it to work by buying a DP > HDMI cable, not converter.

Sounds like you're almost there —
Does the HTC Vive show up as an external display ?
If so , force resolution to 2160 x 1200 / 90 Hz and the
light should go white with desktop in headset.

The GTX 900 series have a small bug with Display Port if you've prior been using the HDMI or DVI port. I experienced this when I bought a new monitor that didn't have DVI. You need to connect to a display port device like a monitor with nothing else plugged in to the card.

Here is a post about detailing this issue with VIVE:
