The RDI is better than the RMC. But in general, the red is really picky to get working well with the LCD. The viewing angle is pretty narrow and that means that setting the contrast is critical.

If you get the contrast right and on an RDI it can look pretty good, but the red is going to be more fiddly than for instance a yellow LCD.
