The switch arrived well protected, with a printed setup guide. The build quality is high and the appearance is suitable for a home setup where something other than another black box is wanted, as well as normal office use. This width is such that it fits in neatly under many common monitor or laptop stands which are roughly 14" to 15" wide with four legs.
The on/off switch is conveniently located at the front instead of rear, and there are cutouts underneath for air flow, and four rubber-like feet to prevent marking the surface where it sits.
The setup guide includes basic information on the ports and operation, but also the details of keyboard hotkeys and on using the mouse for switching. Setup is simple and involves connecting the cables and power lead. All connectors are seated firmly in the case and cables fit tightly and securely. The remote control needs two AAA 1.5V batteries (not supplied) and is simple to open and close.
Switching time is consistently on the order of 5 seconds or so, meaning that as you change the input channel the screen output screen is black for several seconds before the display appears. This seems a long time but is in line with other HDMI KVM switches I have seen. When it appears it the new output display is instantly solid and steady with no flickering. The short video demonstrates the switching time with 2 laptops. 1 mini PC and 1 Raspberry Pi with differing input resolutions, connected in a very simple setup (no extended displays). Switching in the video is via the remote control.
Excluding connectors the signal cables are approximately 56" long and the power cable 48". The HDMI and USB cables are housed together apart from several inches at each end. This makes for neater cable runs but does mean that if your HDMI and USB ports are not close together at the computer end (e.g. a laptop where the HDMI and USB-A ports are on different sides) an extender cable will be needed for one of the two.
So far I have used the switch with two Windows 11 Pro, one Windows 11 Home, one Raspberry Pi (standard Pi OS) and one Fedora laptop. All have worked without any problems at all. I also swapped out the monitor shown for a higher quality 4k one, and video and audio quality are good as expected. The EDID functionality works, and a Canon printer also works on the systems where it's configured.
The auto-switching mode is controlled via the keyboard and is not accessible from the remote, is simple to activate and worked successfully,
Overall, it's a simple and well made switch, has a very easy setup procedure and arrives with good instructions for anyone who has not used a similar device previously. Everything needed to get up and running is included (with possible of exception of extender cables if your HDMI and USB ports are far apart), and two batteries for the remote that is if needed. So far it has been working flawlessly, and is easy to recommend.

This KVM switch has made my desk setup much easier to manage. I can use one monitor, keyboard, and mouse across four computers without constantly moving cables around. Switching has been smooth, and the picture stays sharp at 4K. The EDID feature is especially helpful because the display settings stay more consistent when moving between machines.

I also like having several ways to switch inputs. The front buttons are easy, the hotkeys are convenient, and the remote is nice when the unit is tucked farther back on the desk. USB sharing has worked well for basic peripherals, and the audio output is a nice bonus. Overall, it is a very practical upgrade for a multi computer setup.

I've used KVM switches that cost quite a bit more, and this one honestly surprised me. The picture is crisp, USB devices switch quickly, and moving between four computers feels seamless. If you're looking for a dependable 4-port HDMI KVM without spending a fortune, this is an easy recommendation.

Installation couldn't have been easier. Everything was clearly labeled, and I was up and running in just a few minutes. Once everything was connected, I basically forgot about it because it just works. That's exactly what I want from a KVM switch.

One thing that really impressed me is how stable the display stays after switching. My monitor no longer flashes or rearranges my windows every time I move to another computer. It may sound like a small thing, but if you're switching all day, it makes a huge difference.

I have a work PC, a personal desktop, and two mini PCs for testing, so this was exactly what I needed. The hotkeys make switching effortless, and I love that I can also use the front buttons or the remote depending on where I'm sitting. My desk is finally organized again.

I honestly can't believe how much functionality you get for the price. I was expecting to make a few compromises with an $85 KVM, but this one has been rock solid. Switching between four PCs is quick, video stays stable, and I haven't had any issues after several weeks of daily use. Excellent value.

Finally! A product that works right out of the box and works well. This HDMI KVM switch makes managing multiple machines a breeze. No drivers no additional equipment needed. Just plug it in using the included cables and your off.
I've tried multiple KVM switches over the last few months and have been disappointed in many. Not so with this one. It holds stable connections , Switching between machines is straight forward and responsive. You can use the button on the front or use the Included IR remote. All transitions were quick and flicker free. The form factor is also attractive and low profile. The blue case color is also nice. Mine sits out in the open so it doesn't have the black boxy look suggesting it should be in a data closet rather than out in the open where everyone can see it. Another nice feature is it actually has l/r out port for external sound. Great idea
Would I buy again- Yes

I honestly didn’t expect much at this price point, but the T1410 HDMI KVM Switch really surprised me. It feels way more premium than a sub-$100 product should—solid aluminum build, clean switching, and everything included right out of the box.

Hotkeys and the remote both work smoothly, and switching between PCs is fast with no glitches or screen issues afterward. Video stays stable every time.

For the price, the value is honestly hard to beat.

I bought the TESmert T1410 HDMI KVM Switch to manage four different computers on a single monitor setup, and it’s been a huge improvement for my workspace.

I currently use it with my work laptop, personal PC, mini PC, and a test machine, and switching between them is quick and effortless. The 4K@60Hz output looks sharp and stable for everyday office work, browsing, and video playback. I haven’t noticed any signal dropouts or screen flickering during normal use.

One of my favorite things about this KVM is the multiple switching options. Depending on what I’m doing, I can switch using the front panel button, keyboard hotkeys, the IR remote, or even mouse gestures. The hotkey switching feels especially convenient when multitasking between systems throughout the day.

Setup was straightforward, and the compact design keeps my desk much cleaner compared to constantly swapping cables. The included remote is also a nice bonus when the KVM is placed under the desk or beside a monitor arm.

If you need an affordable and reliable 4-port HDMI KVM for managing multiple computers with one monitor, keyboard, and mouse, this is a great choice for home office, IT workstations, or simple multi-PC setups.
