Pertelian X2040 auxiliary display Review

Auxiliary displays are computer peripherals that're bought by more people than actually need them. Every normal computer has a monitor. Many have two or more, these days. You don't gain a lot by adding another four lines of 20 blocky-pixeled characters to that. It may be fun to have an extra little screen on the front of your PC that tells you what the CPU temperature is, or something, but the system-tweakers who install such things can seldom find a practical justification.
