Review is for: AV Access KVM switch 4KSW21-DM. This kvm performance and ease of use exceeded my expectations. There are 2 modes, kvm mode and usb mode. In kvm mode, you will control one of your PC and in usb mode 2 PCs will show in 2 monitors. TLDR: - I would definitely recommend this one. Solid experience. Great price too for the performance. - KVM and USB modes, which is very unique and not available in other brands. - The product is well made, solid and stable. - Hotkey switching. Fast and no issue. Price: Great price for the specs. I looked around Amazon there are too many low price low quality KVM, I won't choose them because KVM, as a transmission intermediary between computers and displays, requires high-performance video processing capabilities which low price kvm can not handle it, they are USB2.0, no cables included, no 4k, no high refresh rate, and have too much negative reviews. Trust me, you get what you pay for. Appearance: -I was attracted to this look when I first see it, gray, metal body, looks very stable and simple. -It's perfect to modern desk setup. Noise: This kvm is super quiet, I just barely hear any noise from it, just lie on my desktop quietly. Performance: I have PC with NVIDIA RTX 3060 video card and Dell latitude 3520, I usually work in PC, using maya, 3dmax, ps, using Dell laptop for office documents, video conferencing. 2 monitors are in 4k60hz, clear video quality, switching with hotkey between them seamless with no lag, sometimes I switching by button in the front of the unit. -There are 3 USB3.0 ports that allows you to use USB external disk, drive, wireless keyboard and mouse. Cooling: With its metal body, it's NO heat at all in whole day work. In conclusion, this is a quality product, it feels well made and sturdy, would definitely buy and recommend to people.

Overall very good. Box feels very sturdy - cables fit securely. I have this mounted with plenty of room on 1RU shelf in equipment rack. Switching hot keys make sense and work reliably. Front buttons work as well. Switching is a tad slower than my old DVI kvm, but still executes within a few seconds. Video quality good - no glitching. Icons all stay in proper places when switching - EDID appears to work flawlessly. No issues with standard dell mouse & keyboard. USB camera with mic works fine - I did have to set up laptop to select correct mic (was a bit ambiguous). One of the primary reasons I chose this KVM was for the analog audio output. The audio is transmitted via USB from the sources (not through display port as I’d expected). It pops through the speakers when booting up laptop (which runs through docking station). Once source powered on there are no buzzes or pops. This is not so bad, but would be very annoying on a headset… The audio balance was off quite a bit from both sources. I ended up adjusting the left / right balance in the pc/laptop to account for this. I’d blame the speakers, but my old setup did not have this issue. Pros: Decent price Sturdy Solid video quality Comes with usb 3.0 cables Cons: Audio pops when sources are booting Audio balance is off Not as fast switching as my older kvms

This AV Access KVM switch is a fantastic addition to my home office setup! It works exactly as expected, and the build quality feels excellent, promising long-term performance. Connecting my two PCs is a breeze thanks to the 2 HDMI and 1 USB-B ports on each end, making switching between them seamless – something I'm already enjoying immensely. I appreciate the inclusion of multiple USB ports: three USB 3.0 and one USB 1.1. This allows me to effortlessly connect all my essential peripherals, including my wireless keyboard and mouse, as well as external USB drives, without any hiccups. Unlike other switches I've used, this one thoughtfully includes a 3.5mm audio port. Finally, I can say goodbye to long headset cables and comfortably enjoy gaming and music. The switch itself feels robust and well-constructed, with its sturdy grey metal body adding a touch of reliability to my workspace. A particularly clever design feature is the locked power cord connector, which effectively prevents accidental power disconnections – a truly amazing detail. Overall, this KVM switch has been perfect for my needs, and I wholeheartedly recommend the AV Access KVM switch to anyone looking for a reliable and feature-rich solution.

Product working as expected, the quality is great and hopefully it will perform well for a long time. I purchased this kvm for my home office, it need to be connected with 2 HDMI cables and 1 USB-B cable in PC and laptop ends. It make me easy to switch with 2 PCs, so far I'm loving it. The switch features 3 USB 3.0 ports, 1 USB 1.1 port, allowing me to connect all of my necessary peripherals including wireless keyboard, mouse and external USB drives, without any issues. Not like other switches, this unit also includes 3.5mm audio port, I don't need to long cable headset again to enjoy gaming and music. The switch is also well-built and sturdy, grey metel body making it a reliable addition to my work setup. They added a nice additional feature-locked power cord connector, which prevent power cord loose. This is amazing design. Overall, it was very nice for my application. I highly recommend AV Access KVM switch.

This product seems well made and comes with all the necessary cabling. It worked fine initially, but by the 3 month mark, it was apparent the product reliability wasn't there. First the USB A ports started to flake out, causing the USB headset used for audio calls to get disconnected. (Of course, audio calls are work-only events.) Then the HDMI side started causing one or of the dual monitors to go blank at random times. As Murphy's law would dictate, this would always happen on the side of the switch used for the work laptop. I've given up on this device, and have replaced it with a bi-directional USB C 3.2 2 into 1 (also handles 1 into 2) switch to drive the monitors, and a 2 input USB A switching hub for the kbd., mouse, and headset. The USB C to dual HDMI outputs is handled by 1 of the 2 adapters I had already used between the 2 laptops and the HDMI sides of AV Access switch in the original setup. Cost of the replacement setup, Under $60 complete. Cost of the AV Access switch, $140 and it failed after 6 months. You decide where the value is there.

I've had this KVM since June 2023 and it'll randomly glitch out on you. The dedicated keyboard port will not support extra features on keyboards like volume knobs and play/pause buttons on the Razer Blackwidow and will usually not work with hardware security keys. Ever since I've started using this KVM, I've had intermittent problems like sticky keypresses and clicks not registering. As for features, I can game in 144Hz and run two monitors. When it works, it works. The few times it doesn't will make you regret buying this product.

In general, the KVM works decently. But this will depend on what is your setup. Let explain. My PC 1 is a personal computer, i9, RTX2080. My PC 2 is a new laptop XPS 15, i9, RTX4080. I configured this with 2 monitors. High quality HDMI cables, 8K, 16K and different brands to be sure everything works fine. In general, I did not have issues with the image quality, resolution or refresh rates. Let me explain a little why I changed this device after some days of use. Good things 1. This is heavy and feel-good quality. 2. Enough bandwidth to have 2 monitors with 4K@60Hz and 2K@144Hz at the same time with high quality. 3. Support playing video games without issues. 4. Many options of hot keys to change between computers and the configuration is easy (we only need to press two time the key that we want to use and that it). There are many options: control, shift, etc. 5. The hot keys are not an issue if we play video games (I don’t use so much time, but I tried to test to check if this could change of computer while playing) 6. Nice USB mode to use both computers at the same time. But not the option to switch between modes using hot keys or move the mouse automatically between computers (we need to use hot keys to move the mouse in the other computer) Bad things 1. Issues with wireless devices a. In general, the USB ports do not work fine with wireless devices. b. My wireless keyboard was supported decently but sometimes I feel lag and disconnections. c. My mouse has many issues to be detected. This is Razer Viper Ultimate with Charging Dock. I am unable to use the charging dock, because the mouse is not detected through this (this has the option to connect the USB wireless directly on it). So, I had to connect the mouse directly by wire, because the wireless does not work most of the time. d. My Corsair Virtuoso RGB Wireless SE Gaming Headset is detected sometimes, but the microphone was not detected and a message in the computer was shown saying that there were not enough USB ports. Even If I connect only 2 wireless devices. e. My web cam Elgato 1080p60 wired was not detected when I had 2 devices already connected. So, after I connected keyboard and mouse this was not detected. f. In summary, if you try to use this with wireless devices then this is not a good option. The KVM has 4 USB ports, but I could use only 2 with wireless devices. I guess that this should work fine with wire devices (I am not sure, because I did not test). 2. Issues switching between computers. a. When we try to change from one computer to another this take like 3 seconds only to see any reaction on the computer and like 3 seconds more to be able to start using this. For me this is bad because I like to move between computers like many 10 times a day, and this takes much more time that I was waiting for and worst when this fail (continue reading) b. Usually, we need to press the hot key many times to change between computers, because this is not detected at the first time. c. Usually, we need to rebind the default keys because the configuration is lost for some reason (I guess if we are writing and we change the default hot key by mistake, because this is so easy to change ¿Good or bad thing?). 3. Conflict between different resolutions between the computers a. I noticed that if both computers manage different resolutions this can be a big issue with this KVM. For example, if one computer uses 2k@120Hz and another 2k@144hz, then when you try to switch between computers the image is not show and you see only distortion (like when the TV does not have signal). This is the worst thing for me, because sometimes when you need to switch you receive this bad signal and you need to switch again and again and power off the monitor or the KVM to have this working again. I changed this KVM for another option using display port and worked with all my devices without any problem and I could connect all my wireless devices.

This is a great device for those working from home, wanting to watch two monitors and control with only one set of peripherals. The device itself is very well made, with the threaded power jack being an unusually high quality and intelligent touch. I think a design decision had to be made with the USB 1.1 port, which is where a lot of people are having trouble with newer/specialized keyboards. I'm guessing they could have made all the USB ports 3.0, but then hotkey capture would not have been possible? I have just a plain Microsoft Bluetooth keyboard that does not work with the keyboard port, so I am just going to buy a simple, wired keyboard so I can maintain the hotkey support. I do feel like one extra USB 3.0 port would have been nice, though, for a total of four. Overall, however, I'm very pleased with the design, construction, and functionality. It's pretty rare nowadays to buy something and it not be a piece of poorly designed plastic slag. This is the polar opposite. I was able to replace a Plugable USB docking station with this, which served its purpose fairly well, but now I can actually use onboard video of both sources. Update: Had an issue where it seemed like the video signal would just drop, causing the display to just blank out randomly for a few seconds. I'm not a fan of troubleshooting new equipment so just got a replacement. Could have been something else, maybe one of the supplied cables. I also took the extra step of looping the cables instead of bunching them with tight bends. I'm not really sure if signal/energy loss is a thing at these frequencies or use cases, but regardless, I no longer have the problem.
