HDMI 2.1 Switch 4 In 1 Out 8K 60Hz 4:4:4, AVIDGRAM Switcher 4 Port with IR Remote, 4K 120Hz Auto Selector Box Hub Support 48Gbps, Compatible with Xbox Series X, PS4 Pro, PS5, UHD TV, Monitor

I've tried so many 8K switches, every single one has an issue in one way or another, however this switch has NO image relative issues, glitch free with certified cables.The only issue I had with this was that when you press the power button on the LG C2 remote to turn the TV on or off, this little HDMI switch picks up on that infra-red code to change it's channel. Quite annoying, but I now moved it so that it doesn't pick up on that infra-red code.The other issue is that when you press the power button on this HDMI switch's own remote to turn it off, all the led's turn off, however it keeps the HDMI output port active and the input port too! so basically whichever device connected to the active input port still thinks its connected (annoying as it means in the case of a multi-display graphics card it will always think the display is on thus keep applications running on a screen that is not actually on), also the TV will stay on but with a black screen! For now I just turn the TV off after I turn this switch off.> If there is a firmware fix for this, please do get in touch Avidgram!UPDATE: I've recently acquired the exact lookalike of this one but a HDMI 2.0 version, and that one actually does disconnect the ports when put into standby via remote. So it seems the "keeping ports active during standby" issue is only present with the HDMI-2.1 version. I don't think this is a major issue for people using this with consoles etc, but with multi-display computers, may potentially be a deal-breaker.I initially was going to return it for the above reason alone, however after confirming that this switch is the most stable 8K switch on Amazon, I've decided to keep it, though the standby fault may just tip me back to 'return-mode'.Image stability and fast HDMI switching is the main requirement, and this does all that perfectly, very rapid switching, and the blue leds brightness on the front panel is dim enough to not be a distraction but not too dim that you can't see what HDMI channel you're currently on.Each number is like a cutout in the front panel which is lit behind by a blue led, so when you change the channel, the number changes, there is no obnoxious text plastered all over the front of the device like so many others do, also the slick ultra-thin small design of this hdmi switch is a bonus for those of us who prefer the minimalist distraction-free visual layout of our tech furniture.Also it is nice to actually see a brand on Amazon providing a good quality meaty remote control. I honestly am getting fed-up of all the little craptastic remotes so many supply with their devices. If Avidgram can provide a solid remote control at a good price, why can't the rest?!For those who want to know what cables worked with this (I will avoid naming/shaming those that didn't):Worked:Stouchi Certified HDMI 2.1 Ultra-Thin cable for output to TV (available on Amazon)Fibar HDMI 2.1 optic cable for inputs to switch (available on Amazon)The aforementioned cables coupled to this switch gave me the highly-desired stable glitch-free image at 4K 120hz with VRR and HDR enabled along with Dolby Atmos.I didn't buy it for 8K, a way to go before 8K becomes mainstream, but as these switches are effectively just raw throughput data-pumps agnostic of data-content, 8K 60hz should just work fine as it uses about the same bandwidth as 4k@120hz+HDR.

Simply the best HDMI switch I have ever used. Does exactly as advertised and handles all kinds of different signals and resolutions without fuss, all powered by a small USB cable plugged in to my TV. Where other switches have troubled me by switching away from my device mid-use or struggling with picture and audio from certain devices, this switch has no such issues. On top of that, it is excellent value for the number of ports at such high bandwidth. I already have two of these and will buy more as the need arises. Great purchase!

Great quality switch and well built. Only given 4 stars as it does not auto switch to my 4K fire TV stick or my Apple 4K TV box.

Good quality for 4k and 3d and it works but you have to run the same hdmi cables 2.1 and the same make! It's don'ts like mix cables or it just plays up from time to time, it's fast for tuning over on the atomic, the remote is not all that I don't use it.
