Leave the video and power connectors disconnected for now. Note the pin sockets highlighted in yellow, we will need those later. Carefully place the connector from the DExx on to the connector on the right of the DE10 Nano board, as highlighted in red in the picture above, with the SCART socket on the DExx pointing to the back.

Page 18: Scanlines
Dexx-vd_isl Quick Start Guide VideoGamePerfection.com Scanlines Vintage games consoles such as the Sega Megadrive and Nintendo SNES used a special screen mode which resulted in alternating lines on a CRT display being left blank. Typically when people in the retro-gaming communities refer to scanlines, they mean the blank lines between parts of an image on a CRT that were a result of this screen mode. - Page 19 You can now choose the output resolution based on the input resolution. The most common input resolutions are 240p for NTSC region retro consoles and 288p for PAL/European region consoles.
