For retro gamers, the CRT is the holy grail, perfect for playing classics from the SNES and Genesis. But what about the games in the middle—the not-quite retro but not quite modern games, like PS3 and Xbox 360, that run in 720p? As it turns out, a “cheap” projector might just be these games’ best bet. 720p games are at an odd crossroads visually. A CRT, while great for lower-res, older consoles, doesn’t allow the 720p’s HD visuals to properly shine; on the flip side, 1080p and 4K TVs offer resolutions that are too high for 720p. Games will not look as good as they should on these screens, especially 4K ones, because the pixels will not be properly mapped. In order to properly display the signal for these games, you’ll need a 720p monitor. But first, a recap: Video is made up of pixels.
