great little piece of kit

Is doing the job so far. Work well on my parents 1080p tv and helps them switch inputs much easier..

This switcher is now an essential part of my small studio. Gradually I had been accumulating small HDMI monitors for various projects. This now shows all 4 images on one screen, and gets rid of the small pile on monitors and cables that littered my desk. Problem solved. The switchover was really easy, just a matter of plugging it in. I'm using it at 1920 x 1280. I was surprised at the low cost, and the excellent picture quality. It comes with a couple of accessory ears for mounting and the construction is very solid. Recommended.

اولا يشتغل على الجودة 1080 فقط تقسيم الشاشات الى ٢ او ١ كبير و٣ صغير سيء لان الشاشة تكون مربعة والاصل في الشاشة المستطيل يستخدم للكامرات الخارجية ٤ كامرات افضل للرقابة ٤ شاشات صراحة مانصحكم تاخذونه للتلفزيون للكامرات اوكي ممكن

I love this product! I use Hulu Live TV with the unlimited screen option because I tend to use the Disney+/ESPN+/Hulu suite quite a bit, so it's a better value for me than YouTube TV. But YouTube TV does have one feature Hulu lacks, multiscreen view for sports. However, even that doesn't solve the Thursday night problem where NFL is on Prime, so I was looking for a device where I could provide multiple inputs and show them on the screen at one time. For this purpose, 1080P was fine, and this device does it perfectly. But the remote doesn't cover the full functionality of this device, especially when it comes to switching which window is providing the audio at any given time, the remote only allows you to cycle through the inputs (you can't pick the 3rd input directly for audio, for instance). However, this capability did exist using commands sent over the serial port interface on the device. So I got OREI's serial cable and hooked up the device to an old linux laptop and played around with issuing commands. I very quickly evolved that into a fully functional iPhone web app interface (pic attached) and have it running on a very small Raspberry Pi zero connected full time to the device. I now have tremendous flexibility and functionality, where I can quickly switch modes, switch audio, and swap windows. Hopefully OREI offers a device in the future with wifi and app capability built in, it's a game changer! I will say I tried this model (supports up to 4K@30hz) and the next model up that supports 4K@60hz. The more expensive model did support the 4K@60hz resolution, but it didn't support Dolby Atmos, so since I would have to downgrade on the audio I decided it was okay to limit myself to 4 1080P devices and basic 5.1 sound. I didn't try the cheaper model that supports only 1080P because I was so satisfied with the capability to configure this model that I stuck with it.
