Why is the screen resolution only 800x600?

issues, please upgrade your PC’s USB Controller drivers to latest version.
Why the second monitor’s resolution less than 1920*1080?
The resolution you can use depends on the native resolutions your monitor supports. If your
second monitor with native resolution lower than 1920*1080, your display screen can only run at
the native resolution or lower- assuming you have a monitor with a native resolution 1440*900,
when you connect to your computer, then the maximum resolution is 1440*900.
Why does the screen display abnormally or even blank screen?
Please check the following to see if something caused this issue:
1. Check if your system display adapter driver is installed properly.
2. If you have DisplayLink devices installed in your system, please remove the driver from Control
Panel\ Programs and Features\ since these kind of devices may influence the performance.
3. If you have the USB to VGA adapter connected to a USB 3.0 Hub or docking station, connect it
directly to a USB 3.0 port on your computer instead.
4. Out of date USB3.0 xHCI hosts may have some compatibility issues due to the specification. It
could cause either blank/blinking screen, or only low resolutions supported. Please connect the
device to the latest USB 3.0 xHCI hosts.
