Expert Connect9-Channel HDMI Multi-Viewer/Screen Divider/Switch | 1080p / 4K@30Hz | 11 Viewing Modes

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.

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.

Works great, as it should. But limited documentation. Has both rs-232 and Ethernet. Unable to use those since I don’t know what else this bad boy can do. But it does work as it should. Also a smidge up there in price but based on what’s available at this number of HDMI ports in one screen is not too bad I guess

I am a video engineer, and I develop apps for many different devices. This allows me to check channels across all devices on the same screen to see if one particular app or device is having issues when others are not.

It’s a great product. So many different viewing options to choose from and love that I can watch so many football games at once. Great purchase. It’s not true 4k but that doesn’t really matter because most football games are still done in 720 or 1080. The picture is really good.
