No more flickering! Thanks Kevin Pan!
EDIT 1 YEAR LATER The flickering issue is completely gone after a year! I extend my gratitude to Kevin Pan of Technical Support for his invaluable assistance in updating the firmware and supplying new cables, which successfully resolved the problem. --- OMFG, I finally got this KVM working with my Alienware AW3420DW (the notorious flicker monster) and my Dell S2716DG monitor. Both have G-SYNC. No, I’m not a Vine Customer here to review this, though I wish I had gotten it for free considering all the hassle I've gone through to make this work. I was battling some serious flickering issues and spent two weeks juggling various 8k DisplayPort 1.4 and 1.2 cables, on the brink of returning this KVM and throwing in the towel. Just when I was about to give up and possibly set up a shrine to cables past, I stumbled upon 16k DisplayPort cables on Amazon. Naturally, I had to try them. I got two “uni DP Cable 2.1 16k” cables. One goes from the KVM to Monitor 1, and the other from the KVM to Monitor 2. I'm still using my old DP cables (which worked perfectly fine before the KVM), and they are now plugged into the KVM. Checked Refresh rate on both monitors and they are both good, 120hz and 144hz. Switching between my work laptop and gaming rig is straightforward with just the push of a button. No issues at all. It even remembers my window positions when switching back and forth. Now I am typing this review with no flicker in sight! I hope this helps anyone else trying to get this expensive machine to work with their setup!

Was great for about a week
I've tried so many KVM switches off Amazon and have yet to find the one that works reliably. This switched worked perfectly for about a week then started having issues. The mouse and keyboard constantly disconnect from the switch as I'm actively working and the only way to get the switch to pick them back up again is to power it on/off. I've tried moving them to the other USB ports as well and same thing just randomly my keyboard will stop typing as I'm actively writing something. My search for a good KVM switch goes on I guess. *Edit: as of 4/17 I was given a full refund for the KVM by the seller so bumping my rating up a bit. Still wish the mouse/kb cutting out wasn't an issue but for now I'll deal with it

Extremely satisfied with this KVM switch
I'm extremely satisfied with this KVM switch docking station. Setup was straightforward, and it seamlessly supports two monitors and two computers. Switching between my 2 desktops is smooth and fast, and the 8K output delivers crystal-clear visuals.

It sort of works most of the time
Update 9/27/2205 == After putting up with this device for nearly a year now, I've found a better solution (via software remoting) with performance that works for daily use. This KVM does technically operate but it's issues (drop outs, scrambled screens, compatibility, etc.) make it unsuitable for daily 8hr work day use. Their support staff was trying to be helpful and were responsive but the hardware ultimately isn't worth it. If your looking for something to share KVM devices between systems in a low use situation (where tolerating the quirks and issues is feasible) then this could work (although so might manually swapping cables...). If your looking for a device to use all day every day - this isn't it. Update 11/13/2024 == Since my last update I have now confirmed the keyboard issue remains in some form. It no longer appears to redirect input to the wrong computer but instead simply doesn't send input anywhere. The KVM does respond to the Tab + 1/2 to switch between computers so the quick fix remains the same - just toggle the computers and they keyboard starts working again. I do consider this an improvement over the prior keyboard issue (especially since it mostly only seems to happen if the computers have been idle for a while - so greatly reduced frequency of occurrence) but alas this KVM remains in my barely tolerable category likely to be replaced with another brand when I feel like taking a chance again (or I get too annoyed with the issues of this one in daily use). Update 11/9/2024 == After my review AV Access's tech support reached out to me. Turns out there was a possible firmware update but the isn't any way to know what version you have until they send you a link to their tool. My KVM shipped with version 1.0.1 and they had 1.0.2 ready so I updated my KVM to that version. Note that the KVM is picky about USB cables - I had to try 3 before I found one that allowed their update tool to detect the KVM. Not sure why as those same cables work just fine with various other devices. Now on version 1.0.2 I saw no change in the screen sleeping issue (still stays awake with a blank screen - tech support said they would reach out to the engineering team, no response as of yet). However, the keyboard issue is at least partially fixed (possibly fully resolved). They keyboard issue is not reliably repeatable (which is part of why I waited to update this review - I wanted to allow for a reasonable testing period). On version 1.0.1 I saw the keyboard issue at least once ever few days or so. On version 1.0.2 I don't know that I have seen it at all - once I did observe what I think was the keyboard reconnecting but since I wasn't actively typing and I was already on computer 1 (where it likes to swap back to) I can't be certain of what actually happened. Even still, if that was the keyboard issue I've only seen it that once and it even then it wasn't as bad so version 1.0.2 certainly helped the keyboard at least. My rating of the product hasn't changed in light of this - the keyboard issue is significant but also making customers contact support (which was a rough process) just to find out if there even is a firmware patch isn't a good flow. At least publish a tool that can show what version is installed and as well what the current version is so that users can know if a firmware fix is even worth trying. At this point I am still left with having to manually power off either the KVM or the affected display any time I plan to leave my desk for a meaningful period of time - not a good user experience for systems that are supposed to sleep when unused and be ready to use on-demand. (This matters for me since the KVM is located away from the desk itself and not readily accessible and the affected screen takes a while to boot from fully powered off - so the screen sleep issue really is big deal for me. And yes, I have tried every possible combination of cables, ports, drivers, and screen settings - this KVM does not like the one screen for some reason.) Original Review == I have two main issues with this device and some design choice annoyances. The first is that they keyboard randomly loses connection and/or sends input to the other computer while leaving the screens on the current one (e.g. displays are on computer 1 but keyboard is now on computer 2) - the mouse and other USB ports don't have this issue - it's unique the the keyboard port. The second is that one of my displays will not enter sleep mode when the computer tells it to while another does. In effect I end up with one sleeping display and one showing a blank image at full power. Both displays work as expected when connected directly to the computer. This happens regardless of which computer puts the displays to sleep - so it's definitely a problem this KVM introduced. As for the annoyances, the remote is effectively useless. Only the back/next and 1/2 buttons work (on/off/3/4 do nothing). About the only utility in the remote would be to power the KVM on/off (which I wouldn't need to do if the display sleep function was working as it should...). Swapping between computer 1/2 is easily done via the keyboard so the remote isn't needed in that capacity. The second annoyance is an artifact of the KVM's design - the USB ports are on the front but for cable management I want to route them to the back, this requires a pair of 90 degree "up angle" USB adapters per port (I have a keyboard, mouse, and 2 USB cables running to the desk so 4 ports = 8 adapters). I could use a single 180 degree adapter except that they are too short to reach over the top, the two 90 degree adapters add just enough clearance to reach over the top of the KVM. The KVM doesn't need to sit on the desk (and in fact can't due to a sit/stand desk) so using the KVM directly as a USB hub makes the front facing ports useless (this also seems to be a common trend in KVMs - most put the USB out connection on the front instead of the back with the rest of cables...). I will buy another brand in the future due to the first two issues and I'm debating if these flaws are bad enough to justify buying a different brand even now (I use this daily for work)...

Good to go!
This KVM works fairly well, switching between my gaming rig to my work laptop without messing with my peripherals is a dream, only issue I wish I could solve is that I am unable to connect my display (output) from my HP docking station. Unless I hook up the KVM to my docking station to my monitor. So I have the DP port connect to my kvm to docking station, connecting my hdmi to the docking station to the monitor. This work around isn’t bad but just a weird of advice for people in my unique situation.

This isn't the first KVM I've used. Previous ones had little things that were annoying-but-bearable-given-the-service. In some ways with this one I downgraded from the previous one, that could handle more computers, but was single screen and HDMI. But I only have two computers I really need to switch between daily, and I considered fewer cables was a very good thing (I like clean cable management, and the difficulty to get there goes up exponentially with the number of computers). Here are the things this one does better than what I've had in the past: - No weird reaction when proxying the keyboard. Sometimes, they will repeat your keypresses several times. Very annoying when it was Ctrl/Cmd+w in a web browser. - Build quality. It's really well made. - USB and audio connections at the front. It looks less clean on the desk, but my son can unplug the keyboard to plug it directly into the gaming PC (allegedly to shave a couple milliseconds in Geometry Dash), and my daughter can easily plug her own headphones in place of the speaker. If it's easier for them to do, it's easier for me to undo. - USB passthrough. It works with a fancy keyboard/mouse that has dedicated software. Other KVMs also work, but without USB passthrough, you only get the standard keyboard/mouse stuff (goodbye the volume and mute buttons). This is minor but nice. - Connections at the back are clever, as well as the centre of gravity. Especially for the AC adapter: it's screwed it and stays in sturdily. KVMs typically sit at the edge of the desk, naturally pulling on the cables in some cases. Lastly, a very nice-to-have that I don't think is documented on this product's page: hotkeys. It's obviously not the only product doing this, but I love it and it works beautifully. And, once again, very clever setup: it's trivial to change the key you want, and for it not to interfere with normal typing. After 10 days using it quite extensively, I have literally zero complaints.

I've tried a couple of a cheaper KVM device sold on Amazon and both just wouldn't sync both monitors properly. This is a bit more expensive but comes with all the cables so might work out cheaper if you don't have cables, and I was also skeptical when the documentation said if you have issues use the supplied cables but I initially had issues with my original cables but when I swapped it for theirs it works fine. Works great even though I have quite an odd setup. Laptop with thunderbolt to 2xDP adapter and a desktop with a 2xDP GPU all going through the KVM switch into two DP monitors but one is old and is Displayport 1.0 and the other is even older so it's not even HDMI so has a active DVI to displayport adapter to make it DP compatible. Only thing I'd prefer is a wired remote button rather than the button cell remote but that's a minor gripe when I've finally found a switchbox that can cope with my setup!

To get the refresh rates I wanted I needed to purchase some DP 2.1 cables and then Kevin from AC Access assisted in a firmware update for the switch. Now I’m achieving 3440 x 1440 resolution at 120 Hz with my widescreen Dell Alienware monitor and I’m very happy with the stability and features.

Works perfectly, easy to install, all that was needed was inside the box

概ね使用できるが、しばらく使っているとモニターが点滅するようになる。最初はサブモニター側が、ゆっくりした点滅を10分程度の間隔で起きていたが、メインモニター側も点滅するようになった、メインモニター側は素早い点滅を10分程度の間隔で素早く何回か点滅する。問題なく使用していたモニターなのでkvm側の問題と思う。今まで何台もkvmを使用してきたが一番安定していた機種なので残念だ。個体差による問題なら交換してほしい。
