At E3 2017, DisplayLink is touting their ‘XR’ wi-fi answer to remove the tether on VR headsets. Our hands-on with their reference device revealed a sturdy answer with spectacular high quality and unnoticeable latency.

DisplayLink is however one among a handful of companies now working to create the extremely wanted answer to make tethered VR headsets wi-fi. Based in 2003, the corporate has a comparatively lengthy historical past of making the tech behind cable-free computer merchandise, like wi-fi docks and video adapters.

For VR, the corporate is growing what it calls DisplayLink XR, and it’s developed a wi-fi VR reference device for the HTC Vive to point out what it could actually do. In accordance with their enterprise mannequin, DisplayLink received’t in the end deliver this device to market themselves, they are going to work with device producers who need to productize it as an adapter or construct the tech straight into future VR headsets.

The DisplayLink XR answer contains each hardware and software. Software program working on the computer rendering the VR experience compresses the uncooked VR video feed utilizing the corporate’s proprietary compression tech, which is then transmitted to the headset over a 60GHz WiGig hyperlink. The transmission is picked up by the receiver on the user’s head, and DisplayLink’s customized chip rapidly decompresses the information in time to feed it to the headset’s display. Right here at E3 2017 I received to strive the answer for myself.

The DisplayLink XR head-mounted receiver reference unit appears to be like large, nevertheless it’s truly a lot lighter than its size implies. Once I slipped the Vive on my head with the unit connected I used to be stunned on the gentle weight, particularly contemplating that the battery is mounted proper there in within it. With the position on the again of the pinnacle, the unit additionally balanced out the front-heavy Vive (on this case used with the usual strap somewhat than the Deluxe Audio Strap, however they assist that too) which made the headset really feel extra snug by relieving some weight from the entrance of my face.

Within the sq. sales space area during which I used to be enjoying, the transmitter was mounted on the very top of the wall, about eight toes off the bottom. 60GHz wi-fi know-how (like WiGig, the type used on this reference device) is notoriously susceptible to occlusion for the reason that frequency doesn’t penetrate objects very properly. Mounting the transmitter up high is probably going going to be important for attaining peak efficiency for any 60GHz-based wi-fi VR answer (although it ought to be famous that DisplayLink XR is link-agnostic, so so long as the bandwidth is available, it may make use of any wi-fi tech).

The sport I performed was ROM: Extraction which has enemies coming at you from all angles and in addition encourages you to duck behind cowl; moreover the environments are very darkish, and there’s a lot of high-contract particle results—it’s a superb stress take a look at for the compression as most compression algorithms battle vastly to supply high high quality imagery in these situations.

With that stated, I used to be impressed to seek out crisp imagery contained in the headset, even when enemies exploded proper in entrance of me filling most of my view with fast-paced particles. I didn’t discover any evident banding or blocky shade artifacts as I performed. I additionally opened the SteamVR menu to see how the compression handled textual content and menu imagery; I used to be joyful to seek out that it regarded as sharp as I’d count on it from a tethered Vive.

My play session with the DisplayLink XR reference device lasted for about 10 minutes (so not a long-term take a look at by any means) and concerned twisting, turning, ducking, and capturing. By means of all of it, I didn’t as soon as see the picture lower out or discover any stuttering. The latency felt spot-on; from latency alone, I doubt I’d have the ability to confidently inform the distinction in a blind take a look at between DisplayLink’s answer and a direct tether.


The only time I used to be capable of ‘naturally’ spot some visible proof of a wi-fi answer was after I confronted the receiver reverse the transmitter, after which tilted my gaze up such that the acquired moved down (on the again of my head), inflicting my head to be straight between the transmitter and receiver. Even in these moments I didn’t lose the visuals; the dynamic compression kicked in and briefly diminished the standard of the video feed—leading to what regarded like a decrease decision model of the scene—after which in a short time snapped again to full high quality as soon as I moved out of that place.

Even after I significantly stress-tested the system by protecting the antennas with my hand as best I may, I by no means misplaced the picture utterly, although I used to be capable of get it to stutter an honest quantity. For actual utilization although, it appears fairly strong towards fast occlusions like swinging your arms round your head, and I used to be very impressed with the standard all through.
