Bought one of those cheapo HDMI LED projectors which has HDMI input but only a native resolution of 320x240. Internally it down-samples.
I'm wondering if the Pi Zero W can be configured to output at that native resolution so no down-sampling would be needed.
Note: I actually don't need--or even want--the full Raspbian Desktop so I'm not worried about how that UI won't look correct with such a small resolution. The ultimate goal is to have only a single, full-screen app and nothing else since the Pi will be embedded inside the projector, which together will be used as an information appliance.
