Years ago there were a heap of issues using a PAL computer in the USA, because the old-school TV's could not display the signal/resolution, but nowadays almost all TV's around the world can display both PAL and NTSC signals coming in from the Amiga or C64 or any other vintage-tech for that matter. Most TV's have an RGB or at least Video input which is perfect for the Commodore Amiga and Commodore64, and should your TV or screen not have these then we do have an RGB to HDMI converter available as an option.
