Actually, a lot depends on where you have the monitor (pj screen) mounted. If it's higher on the wall, you can get away with a lower back riser. If your monitor is down near the ground, or lower, you will need to build a higher riser.
See Russ Herschelmann's "riser" articles of old. That should help clarify.
Actually, you can search building a riser DIY by googling, it, like anything else.
good luck
