Computer monitors (Southam CV47)
I have a number of working spare monitors of different sizes, from 17 inches to 24 inches, which may be suitable as second monitors. They all have a VGA port. The larger ones also have a DVI port. If your computer has DP or HDMI outputs I also a couple of spare adaptors. The 19 inch one has one bad pixel, which is not noticeable unless you look for it.
