HDMI 2x1 Multi-Viewer Seamless Switch with PIP Function| Support Scaler UP&Down HDMI 1.3a Full HD 1080P | 4 Picture Mode | RS232 and Remote Control

This multi viewer appears to be junk, one Inlet stopped working in three weeks. I use this product for video and camera viewing in Church video system.

Used this for live video projection for an organ concert in a church. The organ is located above and behind everyone so we set up a screen for the audience to watch the organ action in front of them. Setup: two live cameras (tested and worked with all these cameras in various combinations Canon 7D, Canon Vixia HXR600, Go Pro Hero 4 Silver) > HDMI to SDI Black Magic converter > 200 foot run of SDI > Black Magic converter SDI to HDMI > projector at the front of the Church. There is an ever-so-slight (barely perceptible) lag, but it's close enough to real time that it didn't bother anyone in the audience - speaking into the camera came off just fine sync wise. The switching was indeed seamless at most resolutions, but not at 1080p where I would get a blue flicker between switches (this may be because of some other issue in my signal chain, probably not the fault of the switcher). The remote was useful.

I like this device but it is not seamless as the seller states. It shows a black screen or sometimes a blimp when switching. The best feature of this device is the POP because 99 percent of switchers don't have the POP feature. I am disappointed because I needed it to be seamless.

For the price, it is good seamless for lower resolutions. For the higher resolutions, I get a blip on my picture when I switch it. Someone let me know what product will deliver a seamless for the high resolutions.

Broke after just 8 months and seller wouldn't replace or refund.

Works as advertised. Almost no delay in HDMI switching. Quality product, I didn't need to buy the 10x more expensive switchers. Also, the RS232 capability is an added bonus, I rely on it heavily. I plan to use a Raspberry Pi and have a web ui control the unit via REST API -> RS232 commands.

works great! Allows you to move the PiP to any corner and has 3 sizes. Highly recommend this switcher if you need a PiP.

Works great to switch between two HDMI sources. Not sure if it’s my TV, but sometimes there is a slight flicker when switching between inputs, but it’s hardly noticeable and it never drops signal when switching. I also emailed the company to get the RS232 codes to control this via computer and they sent them to me right away!
