The LSC-VGA2 Horizontal Image Reverser from Listec is a VGA/HDTV to VGA/HDTV scan rate converter that allows you to mirror the VGA input signal on the X axis. This functionality allows you to flip your image horizontally on the external LCD while maintaining the image in normal mode on your computer screen.
You can specify the outgoing resolution and refresh rate on the device regardless of input settings. Output timing is constant, which means that no signal interruption occurs if you switch screens.
It automatically detects input mode and timing parameters. The unit can be controlled via its pushbutton OSD menu. Also included is a large memory for real-time frame rate capture and conversion.
