OREI Multi-Viewer 4x1 Seamless HDMI Switch - 4 Ports, IR Remote, Supports up to 1080p, Security Camera, HDMI Switch 4 in 1 Out on Single Display

Great picture quality. I don't find the user interface for switching between Multiview modes as intuitive as my other older unit.

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

Pues funciona pero el control remoto es un poco complicado

Very good product

After doing a lot of research on multiviewers I settled for the orei 4K UHD-401MV. I'm using it on a 4K 100" Hisense TV for co-op gaming. The device itself is very sturdy and the firmware provides enough options to get the best sharpness. There are some things that you need to know about resolutions and TV upscaling before you can get native sharpness. I have 2 inputs, both a PC. When using the picture by picture or quad view I have found that the best sharpness of the displays van de achieved by setting the input signals to 1080p60hz. And the output signal to 4K60hz. This way the multiviewer will display a dot-to-dot perfect image of 2 side by side 1080p pixels that fit perfectly on a 4K display. I have not noticed any delays while using this device with TV in game mode. Although pricy this device does a perfect job and is definitely worth its pricetag. I highly recommend this multiviewer.

Great product, works well and sound is perfect. Not enough people know that this is a solution to 4 TVs!
