RTD2660H Driver Board

This is display driver board. It has multiple inputs and works well with both TTL and LVDS screens. This driver even has HDMI audio support and can drive two 4 ohm speakers directly. This driver has a scaler built in. That means you can use it to drive an 800x480 display but set the computer to output 1280x800 and it will scale the display down. However, the image will be stretched out (distorted) if the aspect ratio of the scaler doesn't match up. For example, if you have an 800x480 display, the aspect ratio is 1.6 so 1280x720 would look stretched out (1.77 ratio) but 1280x800 would probably look OK (1.66 ratio).
