Eazy2hD HDMI 2x1 Multi-Viewer Seamless Switch with PIP (2 Input 1 Output) 4 Picture Mode 1080P HDMI 1.3a HDCP 1.2 with RS232 &IR Control Support HD0018

The device works as described. I can watch 4 sources at once. It is easy to use as the remote is straight forward and I was able to add it to my harmony remote which recognized the device. It does have some limitations like the inputs cannot be rearranged that I can see. So the order for quad view is always inputs 1/2 on top and 3/4 on bottom.PROs:- easy setup- quick switching (about 1 second)- multiple view modes- easily select your audio from 1 of the 4 sources while in quad modeCons- device has locked up twice in a few weeks of ownership and needed a reset- will not passthrough bitstream audio- reduces video quality even when passing through 1 source. My Tivo menu was not as sharp as it was before adding the device. There may have been other visual effects I couldn't notice.- wish you could rearrange the input location in quad view mode.- There is no warrantyEdit 12/7: I had purchased through Amazon Warehouse used and one of the 4 HDMI inputs failed. I don't fault the unit for failing because something happened at my house and I lost HDMI ports on my Cable box attached to this unit and a TV and receiver not attached. Therefore I cannot say that it is low quality, but what I can say is that the company Eazy2HD is a shell company and impossible to contact if you wanted to take advantage of the warranty. I tried selling the current seller Online Happy Shopper to help get in touch with the manufacturer and they refused to help and also spoke English that looked like it came out of a Chinese to English translation software. I am convinced you wont be able to take advantage of the warranty if it breaks. Amazon warehouse came through though and because they couldn't locate the manufacturer, they offered me a refund (though they did make me pay return shipping I think since I didn't get the full amount)

This thing is a little pricey for what it is but it works great. I use this on a 133" projector screen and each source is pretty clear in quadsplit mode. You can select the audio source when viewing them all at the same time by selecting 1 thru 4 on the remote. Taught the remote IR commands to my harmony elite and we're good to go. I don't use the mini transmitters since I have the harmony so I can't comment on how well those work.

For this price I did not have high expectations. Normally multi-viewers run well over $1K. This one so far has been really good.Pros:It works! It seems to be HDCP compliant and has so far worked with all my devices, including: AppleTV (4th gen) Tivo Bolt, Roku, Xbox One and Xbox One S and is running through my Onkyo receiver to the Mitsubishi and Samsung TV's.Multi-view: 2x2, 1x3 and single view all work as you would expect.Remote is easy to use.Very reasonable price.Cons:In the 1x3 view, the main source can be very distorted/stretched. It depends on your source.Regardless of input, output audio is only to the front channels, more details below. No idea why this is but I've not been able to resolve it.No overscan controls. If your source runs over left or right there is no way to correct it with the multi-viewer. Basically, in a 2x2 view, 'some' of the left and right video may get cut off but it will probably depend on your display or receiver.The attached picture shows my display in 2x2 on a 65" Mitsubishi TV, taken with cell phone.Top left picture looks good, top right has some of the the last 'A' of NCAA cut off.Bottom left source (BlueStacks running on Windows) has a similar cut off on the left side.(Sources: Top Left: Roku Stick - TWC app, Top Right: Xbox One - TWC app, Bottom Left: HTPC Window 7 running BlueStacks (with Are You Watching This!) Bottom Right: AppleTV (4th gen) - Watch ESPN app.)Overall, I am really happy with this solution. I can ding it for a few minor things but it does work really well. I'm not sure why all the audio is scaled down. If you have a surround source going in to the device, it will come through the front 3 channels but none of the rear channels and not through the sub. (The rear channels will come through their respective front channels, at least with 5.1)It comes with a serial cable but you'll need a serial to USB converter to use it. BUT the software mentioned in the manual to use with the converter, no idea where to get it. There is mention of firmware upgrades as well but again, no mention of where to get them. No URL's provided for upgrades, updated manuals or support.If you're like me and your goal is to display multiple games/displays on a big screen or projector, this does do the job with a couple of minor drawbacks.

I've had this product for over a year. All in all, it works well. My only complaint is. The output locks occasionally (once every two weeks). The fix is a simple power cycle. Unfortunately, I don't have easy access to my video network rack, so it's inconvenient.

Perfect. Thank you very much. Audio does work for all four inputs. You can't do much customizing and it's quite basic, but we all know these HDMI multiscreen viewers are over 1K, so it's definely worth it if you can settle for a quad view or full screen view.I was hoping for a PIP view for two of the four channels, which I had prior to this but replaced it with this quad viewer because I have four devices. I had a PIP splitmux with an HDMI selector connected to both HDMI inputs in the splitmux so the view was two screen but I could switch between additional screens within that if I wanted.This does exactly what I needed it to and I'm very grateful. The remote is convenient too, you can easily select the screen you want in full or quad view and which audio you want to hear while in quad view.

Probably there is no other equivalent equipment in the market with the aditional features I would find a significative improvement, namely: more then the three sizes availabe for the secondary window (an option to scale to more then a quarter of the main screen without losing the ratio would be enough) and also the possibility of receiving the sound from de smaller screen. I must say my main use is to connected to the PC while using the other input to keep in touch with some cable channel.

Worked flawlessly for 1 year, now all of the inputs are going bad.I own 4 of these. All are now crapping out.Will never buy again.

Can not control via RS232 without using their Windows program. No command codes available. Can't use unless you both have Windows and are willing to install their program on your PC.
