Review on Thinlerain Portable 3840X2160 Brightness Compatible 15.6", Built-In Speakers, T-156-4K, 4K, HDMI by Patrick Lucas

Maybe I could live with 30 fps because I'm not a big gamer. However, the brightness was too far for me. So dark that it effectively negates any benefits of 4K resolution. Even in a completely dark room, this is unacceptable. It's pointless. This particular model does not have a VESA mount and this magnetic file holder is very weak. I bought three of these "mini monitors" from three different brands. Two on Ebay and one on Revain. All cheap build quality. Looks almost homemade. I would not be surprised if these things are assembled in a non-standard shop in Shanghai from improvised materials from large factories.
