This TESmart KVM switch is designed for users needing high performance, especially gamers and professionals. It supports 4K at 144Hz and 8K at 60Hz, and it uses the latest HDMI 2.1 and DisplayPort 1.4 standards, plus EDID and VRR. This switch is particularly useful for gaming, where low latency and high refresh rates reduce tearing and stuttering. It also handles dual monitors for two computers, making it versatile for streaming or multitasking.EDID and VRR Support:EDID (Extended Display Identification Data) support ensures that monitors display correctly without resolution or icon rearrangement issues, a common problem with cheaper KVM switches.VRR (Variable Refresh Rate): Essential for gaming, VRR synchronizes the monitor’s refresh rate with the graphics card’s frame rate, significantly reducing tearing and stuttering. This premium feature sets the TESmart switch apart, as it’s often absent in more affordable alternatives.An added bonus is the inclusion of all necessary cables, which are of high quality, saving from additional purchases and simplifying setup.While the price may seem steep, this KVM switch is one of the few that supports 4K at 144Hz with both EDID and VRR. When factoring in the premium cables included, it offers solid value for its performance and convenience.

HDK203-M242 computer 3 monitor model. 2 DP inputs per computer 1 HDMI 2.1 per computer. 3 HDMI 2.1 outputs.I received this item Nov 29th 2024, it's been on my desk exactly 30 days at this point. I work from home 5 days a week 10-12 hours a day at my computer. I'm running three 4k screens at 120 Hz each and HDR on my Neo G7 43" center main monitor. So far the device has been rock solid.I spent MANY hours looking for a KVM to fit my needs. I was very close to pulling the trigger on a Level One Tech KVM when Tesmart released these new 8k (all black) units. The Level One was significantly more expensive (HDMI 2.1), had less features, and only supported 2 monitors. Still I was hesitant as during my research I found many poor reviews for Chinese KVM's, Tesmart included (older models feedback). But the new units looked well thought out, the feature set was rich, and the savings of $200 had me interested. When I saw you could purchase on Amazon I figured it was worth the gamble to see. So far my experience has been very positive. Only time will tell if the device holds up in the long term. If it does not I will come back and update my review.----------Positives -1.The build quality at least from the outside is great, all metal, and looks slick.2. The switching speed is much faster than most KVM's I've seen. The black screen between switches is hardly anything.3. The hotkey commands are a game changer and well implemented4. I've tried several keyboards and mouse and they all seem to work plug and play5. As of now I've seen absolutely no determent to graphic quality at least with the demands my screen has. If you're pushing the very limits of the device maybe that would be different I don't know. But at 4k 120hz HDR it's been perfect.-----------Negatives -1. probably my biggest grip so far is this does have an active cooling fan. The fan is a bit noisy which cheap fans usually are. They should spend just a tad bit more to put a higher quality fan in there. Over the 30 days I've had it I do barely notice it anymore as I've become used to it but some users may be more sensitive. Some users may opt to turn it off which there is an option for but likely would have a negative effect on longevity of the device. If the device last past the warranty period I'll likely put a Noctua in it but right now I'm leaving as is.2. The physical power button and screen switch button if you choose to use it could be better. The button feedback isn't the greatest. I believe most people will opt to use the hotkeys anyways though as its way more efficient.----------Customer feedback for next models - (not really negatives just points that could make it better) -1. The keyboard and mouse USB ports should be put on the back. Leaving only the audio port and USB ports for things like USB drives on the front. This would provide a better overall desk look with cabling.2. Some better product documentation on how the device functions. Like I'm not sure what kind of magic they are doing to achieve 48Gbps on the two DP 1.4 inputs which output to HDMI 2.1. I also don't have a way to test to make sure that is in fact happening. I opted to use the one HDMI 2.1 input and the corresponding HDMI 2.1 output to run my main higher demand Neo G7. If the throughput is different for the DP 1.4 input and corresponding HDMI 2.1 outputs that should be made more clear. It wasnt a huge concern for me as I only needed the full bandwidth for one monitor but it may be a deal breaker for someone else. I'm not saying this is the case I just don't know how they are taking the two DP 1.4 inputs which are around 30Gbps and getting a 48 Gbps output to the HDMI 2.1 ports.---------Overall as of today I am happy with my purchase. I look forward to what they come up with when DP 2.1 becomes more widely available! As of right now I would recommend this KVM (or this series the all black box style 8k KVM's) over pretty much any other KVM on the market as of Dec 29th 2024 if 1. you need the features and the resolution support 2. you're not made of cash and spending more on the Taiwan options is a stretch for you.

I have spent 20+ years in the AV and IT industry. I have tested hundreds of devices over the years. At one point, I spent four years testing 5-10 products a week. It does not take me long to judge a product and decide what I like and do not like.If you are looking for a 2 computer, 3 display KVM that reliably works well, this is the KVM you are looking for.My setup:- Three displays of various sizes and orientations (One is 1080p, one is 4K, and one is a very wide display flipped in a portrait orientation).- Computer number 1 is a desktop PC running a dated NVidia RTX 2070 video card. This PC has a lot of other peripherals connected to it as well for gaming, etc.- Computer number 2 is a laptop that is connected to a Dell dock.- Both PC's are feeding the KVM with 2 DP's, 1 HDMI, and the USB cables that were provided with the KVM.- On the KVM, I have two Logitech receivers connected (The keyboard uses a modern Logitech Bolt receiver, the mouse uses the older Logitech receivers because they do not make my mouse with a Bolt receiver yet).Installation:The installation experience was relatively straight forward. After running all of the cables, I powered up the KVM and began configuring my two computers. After getting the PC setup properly (Windows display settings, resolution, orientation, placement, etc.), I switched over to the laptop and completed the same setup. In all fairness, both computers too a couple reboots to fully sync, but they have been flawless since then.Analysis:- High quality build - I love devices like this that are all metal and look nice. At first, I was tempted to hide it under my desk. After spending some time with it, I decided that it needed to be on top of my desk. It looks nice.- It works well - I can quickly switch back and forth and it rarely skips a beat. Once in a while, a display may lag a few extra seconds, but it doesn't happen often.- The remote and the hotkeys are awesome! With some practice, I will be able to quickly switch between computers just by using the hotkeys. Once in a while, I will use the remote too, so it is always within reach.- In my setup, my audio system and my camera systems are separate. With this setup, I can hear notifications coming in from both computers. Why is this important? It tells me something that is key to the success of this product: When switching between computers, the computers do not "see" the displays, keyboard, nor mouse "drop" offline. In other words, I do not hear the familiar sounds that Windows makes when a USB device is disconnected or when a display drops offline. This active connection between the KVM, the computers and the peripherals is what makes this device so valuable.Complaint:- Minor complaint - Sometimes, the fan turns on and off after a few minutes of usage. Due to the placement on my desk, it distracts me at times. I might play with some of the settings and adjust this.I am going to continue using the device and I will update my review, if anything changes. At this point, I am very happy with this purchase. It has revolutionized my desk setup in a very positive way.

Great Kvm with a windows machine and macOS M2. Not a single issue out of the box. If you want simple but flexible this is the one.
