Testing reviewes for 3 models of HDMI multiviewers
1. 4x1 quad viewer QV401K vs QV801 vs MV801
QV401K: full screen display and text from PC is clear enough to read easily. It can be a perfect solution for higher demand of picture definition, especially PC text reading.
QV801: automatically adust the PC resolution to 800x600 in order to get the best quality of display. The text is also clear and readable. but the screen is not fully displayed. Picture quality is lower than QV401K but acceptable for most of the projects.
MV801 (1080p): Output resolution can be scaled to 4k 30hz but the actual picture quality cannot reach UHD. For certain, it does not suitable for PC. Text from PC is blurry and unreadable. But do not turn your backs on it rushly. It can also be a compromised solution for video watch only and cost-sensitive projects.
It is with KVM function, but it is a pity that the USB port is USB 2.0 but not USB 3.0. You can control 4 PCs via a set of keyboard and mouse. There are two ports of USB docking valid for PC 1 port.
