This guy made his own video "card," you can too.

I saw these videos below and thought that this was pretty [H]ard. It isn't a video card in the classic sense as it can only output one frame at a time before needing to be reprogrammed, but it is still technically a video output device.

Cool. As. Shit.

Taking in the cost/value of my time...I'd be better of buying a reeal card...25 years ago I would have found it cool...today...meh

what??? No DP or HDMI? No 144hz refresh rate? can't play crysis?

I played around with VGA output using a basic homemade dac driven by an FPGA about tn e years back, and I could never make it sync with my CRT.

I gave up on doing anything involving displays that. It' s a pain in the ass.

Yeah, we had to interface an FPGA board to a VGA screen for a college course. I don't remember the details, but the ultimate project was to program a very simplified version of the game "flappy bird" using a digilent basys 2. I don't remember if our board actually gave us color control or if it was mostly just digital: red on/off, green on/off, blue on/off. But I do recall having to deal with the hsync and vsync.

Yeah, this was also for college c;lass. I think only a few of us succeeded at making it output anything.

Luckily, failure is still worth something. I thought I had configured properly, but who knows? My analysis and code was enough to get em a B, and it was my last class before getting my MS.

As a programmer first, and a circuit troubleshooter way last, The one insight ftom this six month distraction: VHDL in sequential mode is just ADA. My professor had never made this observation., but knew how the magic of VGA sync worked

Never used ADA, and have very little experience with VHDL. I've only been using verilog. Like most other digital designers I usually avoid comparing any HDL to any programming language, because once in a while you see someone trying to create verilog for synthesis as if its a regular programming language, and thats when things typically break horribly.
