Are you an avid retro-gamer who misses the good old times of CRT TVs when playing video-games? Do you feel that retro-games don’t look good on LCD TVs? If you answered YES for any of the previous questions then probably you may want to check out RetroVGA ScanLines Generator!
RetroVGA is an adapter that connects between your PC VGA port (or any console capable of output VGA signal either natively or through some cable/adapter) and your LCD TV/Monitor and generates scanlines, bringing the feel of the good old TVs to modern screens!
Scanlines are generated by hardware, not software, so even if your favourite game or emulator doesn’t provide a scanlines “filter”, you’d still get this nice effect very accurately.
Take a look on how a retro-game looks like in modern LCD screens:
Too pixely, huh?
Now, this is the effect you get when you are using RetroVGA on a LCD TV/Monitor:
Smells like old CRT TV, right? 
It’s self-powered from the VGA cable and you are free to play with the 4 switches at your will without being afraid of getting things fried!
The four switches in the board are:
ON/OFF: Turns the scanlines effect ON/OFF
EVEN/ODD: Tells the board to draw only ODD or EVEN scanlines
WIDTH: Tells the board to draw double (thicker) or single scanlines
VSYNC: Inverts VSYNC signal. Need to change it when you’re using a VGA resolution different than 640×480@60Hz or 1024×768@60Hz, otherwise scanlines won’t work.
