To a certain degree, yes. I have seen Image Retention in both LCD and Plasma. I know that with Plasma, you can reverse Image Retention. I don't know if the same is possible with LCD. The only way to fix Image Retention on a CRD projection, weather it's RP, ro FP, is to replace the CRTs. The good news is, you can replace them one at a time. The bad news is, even that is, pricing is still kind of high. So, say I have a 9" CRT projector ( I hope to have two.

) One of CRTs for each projector is about a grand. So, multiply that by three, that equals six grand just for replacement CRTs.
So, Figure, about $7500 for each Projector, and maybe $800 for each tube, not, then the lenses...
Ease of setup, and little or no timely maintenence, and DLP/LCD/SXRD become pretty attractive. so long as you can live with the draw backs, like Rainbow, or some screendoor, or black levels, or lack there of.
There is one big problem with CRT, besides the work. There are no HDMI, or DVI inputs. Makes Blu Ray and HD DVD a bit of a pain to use...
