The Hackaday badge used a 480x320 display. The LVDS display you are currently using seems to be 480 x 272, which does not seem to be compatible with anything much.

The 480x320 is compatible with a Gameboy Advance 240x160, but not so much with the original Gameboy resolution of 160x144.

A 320x240 display would be more compatible with VGA, and 640x480 even more so.

Another consideration is how many cycles it takes to write a pixel and how many dots there are in a frame, and what clock speed is needed to get a decent frame rate such as 50 or 60. A larger screen might need a wider bus. It looks like it takes 7 cycles to write a pixel with the current LVDS screen.
