Thanks for ask these replies! I'm pretty new to displays do this has been very informative. For the project in working on, I'll be using a smaller screen, maybe with a touch screen. Something like this:

According to the page it accepts an 8-bit signal. From the looks of it, this would be able to directly use the RGB/TTL signal.
nope - as chris points out, that's a "MCU" style interface (similar to the old IBM XT bus). 8-bit data/address, 1 line to say "it's address or data", 1 bit to say "it's read or write" and another for "clock".
you _could_ use it... you'd have to track down the datasheet for the controller IC.
basically.... welcome to my world! now you see why the project's taken 5 years! you've been on this for 2 days and you're tracking down just *one* of the components - the LCD! now you also have to find a trusted supplier...
Another question I have is about SPI based displays. There seems to be a lot in this size range.
yes.. because the controller ICs are extremely low-cost.
Would those be able to display hardware accelerated video?
not a snowball in hell's chance. 25mbit/sec *serial* data transfer - you can do the maths.
Is that even a concern with this small of a display?
try to find a video of the Adafruit HX8357D SPI-based LCD, you'll see that the drawing rate is veeery slow.
