There should be something in the HDMI or Display Port standards to help people who try to do this kind of thing.
Like by allowing some vertex data to be passed over the standard if requested, or something.

I'm not at all impressed. It seems to work, but the effect is just barely noticeable - if you try to look for it. With delay less than 1 ms with what's probably not very much processing power, this should be almost free to do with any proper GPU. A typical console game runs at 30 frames per second, which is about 33 ms per frame. If this works as promised, the extra delay should be 1 ms at most, and probably significantly less for a more powerful GPU. Still, we don't see this done pretty much ever, I think. That's probably because the effect is way too subtle. None of the examples in the video concinced me and judging by the other images I've seen, the difference compared to proper AA is huge.

Linus said it was better than SMAA or FXAA in games, through below what MSAAx8 does.
Thats impressive still for something that doesnt impact performance at all, and is usable with any HDMI device.

SMAA & FXAA arnt "free" on a gpu, it costs performance. But this isnt really for PC users, this is a thing that ll improve Image Quality for console users, who cant just choose to put a extra 100$ into a better gpu.

No one here has bought one and has some first hand experiance?

We sell them at my store. We've tested them here, too. They're not worth it.

But they do improve the image quality when hooked up to a console?

"not worth it" is subjective, and if its the only way you can improve your consoles graphics? 100$ is alot though, but might be worth it to some.

I imagine alot of nintendo switch games dont run high AA modes, and at 720p I could see such a Mcable helping out alot when docked.

What did you test it on? and was there a noticeable upgrade?

this is from a PC:

(SMAA seems better in this game)

Here mCable beats no AA or FXAA.

We tested it on a 65" 4K Samsung and Sony (it was last year, so we were comparing the KS8000 and 850D). The Sony's built-in upscaler (the X1 is designed specifically for upscaling and visual nose algorithms) was better than what the Marseille was capable of accomplishing on the Samsung, and using the cable on the Sony made no visible difference. While it did make a difference in the Samsung, it wasn't a $100 difference.

If you want post processing why not buy a better TV just instead and turn cinema mode on.

I don't care what he says because the effect is still barely noticeable. It is there, but it's not helping very much. It's helpful, but I don't think it's even close to being worth the cost. I know AA isn't free (far from it), but I'm assuming this cable doesn't have very poweful hardware despite being able to do AA, so a proper GPU that's probably quite a bit faster can probably do this in even less time, which means the time it takes to apply this sort of AA is quite small and probably almost negligible compared to a typical frame duration.

Okay guys.... cube001 from Neogaf, bought a cable and tested it on his Nintendo Switch!!!!

These are camra shots the guy took, from his TV.

Showing the results of the cable used on a Switch.

Its a huge boost to image quality, imo.

Heres some from Zelda:

Again this looks noticeable better.

If this cable was like 50$ it would be a no brainer, that ever switch owner should get one of these.

But at 100-150$.... its good, but pricy.
