The new Nvidia GeForce GTX 1080 and 1070 are the graphics cards to buy for a futureproof virtual-reality PC. Their price, performance, and some special new VR-specific rendering techniques set them ahead of the pack. But if you buy one today, you may have some trouble connecting it to an HTC Vive virtual-reality headset.
Don't get me wrong: the GTX 1080 and GTX 1070 both work with the Vive, but apparently only over the video card's HDMI connection. Angry users on the official Nvidia Forums and on Reddit have been complaining for over a month that when they plug the Vive into the card's DisplayPort socket, the headset fails to start up.
Why not just use the HDMI port for the Vive? That can be an issue for users who are already using that HDMI port to connect their computers to a monitor, which is still generally required for HTC Vive users. (They can't just immediately use the headset to navigate the Windows operating system.) Also, most graphics cards only offer a single HDMI port.
While a Nvidia Forums support rep wrote on June 9 that "We are still investigating this issue," a fix has apparently yet to be found. Yesterday, noted reviews site Tom's Hardware also confirmed the issue on one of its own GTX 1080 graphics cards.
Nvidia didn't immediately respond to a request for comment. An HTC rep said he would look into the issue.
