If you are going to use a small monitor or television, get a high resolution device instead of a high pixel density device.

If you have a PC and want to use a small monitor, you would benefit greatly in getting a high resolution display instead of high pixel density. A small high definition monitor can be awkward to see a pixelated image from. A 23.6 in 4 K monitor will help you much more than using a 27 in 1080 p display.
