Nope, that's the beauty of HDMI and the Raspberry Pi - the port's there, you plug in any HDMI normal monitor and the display appears on it. If you use a monitor that needs special timing/modes (as some small/specialized ones do - I have a 10" LCD HDMI monitor
like that), then you'll probably have to add a mode line into /boot/config.txt
, but that's a one-time thing, not especially difficult, and should take care of any OS you load since it is processed early in the Pi's boot process.
Custom-patched OS's are generally for displays that plug directly into the Pi's GPIO header, and many of those can now be handled - on Raspbian - by loading a driver at boot time rather than needing a patched kernel, as support for them was added to Raspbian.
Gentle suggestion: if you're just starting out with the Pi, stick with Raspbian until such point that you've become well-versed in it and find it doesn't meet your needs. The experience you gain will serve you well on the other OS's and Raspbian is what 80-90% of the other users are running, so support is much easier to find for it.
There is a company that makes smallish screens for the Pi that fit on top but use HDMI for the video and USB for the touchscreen, for decent prices, but the name escapes me at the moment. Perhaps someone else can supply it.
