4 Ports Quad HDMI KVM Multi-Viewer/Screen Divider/Switch | 1080p @ 60Hz | 5 Viewing Modes | USB Switch | Shares 4 USB Devices on 4 Computers

I have four desktops hooked up to this to use as a home network. I got this so I wouldn't have to buy a bunch of monitors. I can display all four cpus on one screen.Tow things:1. You can use a wireless mouse, but the reading is a little weird, not too off but don't try anything that requires precision mouse movement. Wired mice are normal.2. You have to have a keyboard with a number pad or have a number pad separate because it reads all the numbers from the numpad and you HAVE to have an * key to switch the screens on the keyboard. You can't use shift+8.Also, it doesn't say anywhere in the description or EVEN IN THE MANUAL, but THERE IS AN OPTION TO MOVE BETWEEN ALL SCREENS IF YOU ARE HOOKED UP TO MULTIPLE SYSTEMS. JUST HOLD * AND PRESS S. You can move between all of your independent CPUs while they are displayed in quarters on a single monitor or on separate monitors without having to switch between them, which is very convenient. I figured this out by accident, and isn't listed anywhere in the manual, in the description or on the website.The only other drawback would be if you have a programmed mouse or fancy lighting thing like I do, it will go to default glow setting while switching between systems. I haven't played with it that much to try to fix it, but this is what I've found so far. If you are planning on hooking up multiple systems and want something solid, I highly recommend this KVM.

Fantastic product that does exactly what you see here. You can combine any number of up to 9 HDMI video sources on a single video screen. Great for home based business, sports fanatic, video cameras, you name it anything that puts out an HDMI signal. Video quality is fantastic, you aren't just limited to 3x3 the will actually support a number a display formats. Comes with remote. Also says it supports RS232 to control the device however I have never been able to get it to work. I did not score down for it however because the product is just that good especially for the pricepoint. I liked it so much I bought two of them.

The media could not be loaded. Initial observation is that this thing is built super solid, nice heavy weight to it. Also has enough room for me to drill holes in either end in order to use zip ties to mount to the back of the tv. The remote is easy to figure out and use, but a heads up, the infrared is going to require line of site from the remote to the unit. Overall I’m stoked about being able to put multiple games on at onceUpdate: splitter is still great, but a heads up, a couple of the split modes construe the aspect ration; understandably the tv can’t correct because it sees one image (on a 75” widescreen). Going to keep at 5 stars because I haven’t noticed myself wanting said modes..... video is of me pressing “mode” on the remote to cycle through the options

I suspect this item is used and not new. The box it came in is pretty ruff. One of the corners was bashed in. The outer cardboard sleeve looks like it had gotten wet because the printed paper on the cardboard is bubbled up all over. After removing the sleeve I notice a dried white powdery substance adhering to the inside of the sleeve that feels gritty when touched. This better not be Anthrax! Giving 1 Star.April 2021. Update on this HDMI KVM after having it for about 9 months. It works really well. I have 3 laptops and a server hooked up to it. Very solid performance with almost no issues except one. The problem is rather annoying. The asterisk key on the keypad doesn't work. I fought with my wireless keyboard and finally narrowed down the problem to the KVM. I saw another review that mentioned the same thing a moment ago. I wonder if a wired keyboard will work properly. Also the white powdery stuff on the box turned out not to be anthrax so I'm changing my rating to 4 stars.

This should perhaps be a 5 star device given that you can't achieve exactly what it does, (assuming you don't need a KVM switch), for anywhere near this amount of money. Very good value.They really stripped this down to it's basic function, but it is remarkably, and satisfyingly capable in that area.I only take a fraction of a star off because there is no LEDs at all, either on the front or back, that indicate what mode the machine is in or which source is selected, if it see's the remote, etc and there is no way to bring up an OSD (aside from a basic number) , so it is very very possible to get into the weeds and be looking at blank or stretched screens.The little tiny pamphlet looks simple but oddly you really have to look at it and get used to the mode changes to make good use of the switcher. Once you know how to get around in the system, it can do almost anything you want, but it's a bit odd. But that is fine. It is a very interesting set of combinations of screens they choose, it can't do all re-combinations but you will find it remarkably versatile in how you can rearrange your screen.However if you were to lose the Remote Control you would really be in trouble,as there is only 1 button that .. it's not apparent if holding it down does anything, or how you would switch from 4k to 1080p, or the sub-modes, or change the primary input, etc. Lots of things.So, with the 100% lack of any feedback on the device itself, and the 99% dependance on the remote, combined with no real OSD I guess is worth deducting 1 star for. It would be the failure of any one of these areas that unfortunately would make the device basically unusable.Given that it is delicate, and gets hot (if you put a lot of high rez input hi freq inputs into it, you should give it extra air if not direct ventilation. It is has no fans, 9 high freq inputs will obviously get hot.And it feels a bit delicate, if you are going to plug things in and out a lot, you should get some short HDMI extenders (or cheap passive switches, might as well) so that don't wear out the sockets or stress the backplate.So yes it's a bit fragile and the operation is borderline and I'm kinda worried I will lose the remote.But that being said, it is absolutely great, hugely convenient and space saving for me.I have all my laptops connected to it, so if I want to see them side by side or 'project', it's just a click away.If I overload a machine and I feel like watching something to take a break,there's another machine I haven't been using I can bring up with just a click.And it enables me to very lazily check on things by clicking around on the screen so I can decide if I actually want to go over to the machine.This is 100% been what I needed, I have a ton of KVM switches, I sort of am collector I guess, but none of them do exactly what this does. I've been using it to the hilt, leaving it on 24/7 for a week now, I will come back and revise if it overheats.ugely convenient and space saving for me.
