Do I need to pull up DACBLANKn too ? I never paid any attention to it. This isn't the worst possible test for SSOs, since there's a 1 pixel red line between the black and white pixels, so only a maximum of 11 switching bits at the same time. In any case, the problem would not be with the SOT-223 regulator, but rather the inductance of the traces (including the ones inside the TQFP package). By the way, since I don't have easy access to 3.3V supply, I just patched the output of the 3.3V regulator into the 3.3V input on the board, so the single regulator is powering both video DAC and FPGA. So far, so good

If it gets too hot, I'll add a beefier regulator on the board somewhere.
I did mount R5-R7, but since I didn't order any 75 Ohm resistors (I figured I'd just pick the resistors from my standard set, until I realized there were some non-standard values), I mounted two 150 Ohm resistors on top of each other.
I haven't ordered the SyncRAM yet. I wanted to make sure everything else was working first. For now, I'll just play around with the bare FPGA, and see what I can do with the block RAMs.
Edit: I did notice some weird interference on the screen, but then I figured I could make it go away by disconnecting the JTAG pod. Also, I noticed a change in overall brightness when doing that.
