All Hype, No Mirror – Hyper Mirror Wireless HDMI Review
|Hyper Mirror is a kickstarter project that’s gained a lot of traction, racking up nearly half a million pounds in backers between kickstarter and indiegogo. It’s a wireless HDMI solution, uses 60GHz much like Intel’s WiGig, and much like Intel’s solution, doesn’t work reliably. Lets take a look at this, but first, if you haven’t already, consider subscribing for more videos every Monday, Wednesday and Friday!
So, Hyper Mirror. It comes as a pack of a receiver and transmitter, with the transmitter being a phone clip with a dongle in the back. That lets you connect it to a medium to small phone, plug the small USB C cable in, and in theory have it cast your phone to a nearby display. Your phone will need to support displayport over USB which only a relatively small subset of phones do, and even then your mileage may vary.
If you’d rather not use it with a phone, you can remove the dongle from the back revealing an HDMI connector you can plug in and, again in theory, have it cast your screen wirelessly.
The transmitter is a standalone box, with mini HDMI and USB C, and comes with a clip to mount to your TV, although the way it connects is incredibly frustrating and will break quickly.
Spec wise, these use a 60GHz wavelength, the same as Intel’s wireless display solution, and has a quoted range of 5m, down from 7m from Intel. They also quote just 4gb/s connection speed, again lower than the 7gb/s from WiGig. It’s capable of 1080p 60fps only, despite quoting “ULTRA HD” support on the box. They do however quote this as being “0 latency”. Let’s test that.
As usual, my test is total system input lag, so from the LED on the mouse going out, to the gun firing in game. This is on a gaming laptop, and the Gigabyte G32QC I reviewed recently, and of course at 1080p 60fps, despite both the laptop and the monitor being able to do much higher. Over HDMI, the average input lag was 69ms. With Hyper Mirror, the average was 76ms, and the maximum latency was almost 10ms slower than the HDMI cable’s maximum. So no, it’s not 0 latency, but it’s not so consequential that it’s a major problem.
But the latency doesn’t tell the whole story. While the actual latency wasn’t too bad, the artifacting on the display was pretty offputting. The motion blur effect, the smearing, jitter and stuttering all made the gaming experience less than ideal, and the transmitter and receiver were only a foot apart. It’s also not reliable either, with the display cutting out randomly, and I have to call BS on the range too, as I walked the laptop at most 2m from the display – the length of the power cord, and it cut out and refused to reconnect again.
When I tried using my under-desk PC, it flat out wouldn’t work. I had it connect for 1 frame at a time, by hanging the receiver under the desk, a foot from the transmitter, but was incredibly frustrating to use. The same goes for my phone, a Oneplus 7T Pro which does support DP output, but the Hyper Mirror would only connect for a few seconds at a time before dropping out again, all within 50cm of each other.
All of this doesn’t sound great, but it gets worse. They want near on £100 for this kit. That’s insane, for something that, at least in my testing, barely works. Sure, playing mobile games on a TV wirelessly with low latency is pretty cool but other than a ‘cool factor’, I’m struggling to see a real use case for this even if it did work. 5m is too short to not be able to easily hook up a cable that’ll work without issues, will let you run higher refresh rates and resolutions, and won’t artifact like mad. I also really don’t understand why they say you can use it with the nintendo switch dock, besides maybe peak laziness of not getting up to plug it into the dock and instead having the dock next to you.
If it’s not obvious, I don’t think you should buy this. Maybe with some refinement of the connection, inclusion of the rest of the WiFi bands – Intel uses n, ac, ax AND 60GHz ad, whereas it seems this only uses the ad band, might make this a more viable solution but for now it’s a solid no from me.
