what's the best monitor for the 5dm3 with 1.2.3. build??
A TV from 1946. A cardboard box that says TEEVEE LOL on it. A picture of a tram. A cat.
I would recommend an hdmi monitor with a resolution of at least 800x480 (1280x800 is even better). I like marshall, and smallHD and it's important for the monitor to support peaking and crop marks so you can turn global draw off when you need to.
