Timely update on this thread, as I am just starting to consider a replacement for my MITS 55" HDTV. After over 10 years, she's ready to give up the ghost I think (or should I say gain the red ghost!).

I had been delaying waiting for LCD/LED combos to become the same or larger size, and come down in price. However, all the recent deals I've seen on the MITS DLP/RP screens sure are tempting since I have the room to go up to at least the 73" (and the viewing distance is good, the 55 is really a tad small).

I have only been able to see the DLP in relatively dark showrooms. How do they work in a family room setting where there is light, and sometimes direct light on the screen, when compared to LCD/LED?

Also, if I'm reading the end of this thread correctly the MITS/DLP/RP displays 1920x1080, but it's doing it through some electronic trickery (trying to avoid saying "magic and mirrors"), is that correct? Does it affect the usefulness of the screen as a gaming/computer monitor at all?

I would suggest having your current display looked at unless you just have a hankering to replace it. CRT displays do require recalibration and RPs require some annual maintenance to keep them looking their best. An ISF calibrator, THX calibrator or service center needs to adjust the focus, b/w tracking and convergence along with a lens and possible mirror cleaning. Often times this alone will exceed the response you had new out of the box (provided you have not worn down your CRT phosphors) and many feel like they have a new TV after the service.

Since you claim a 73" would work out the 55" has to be too small in which case I fully understand why you would consider replacing it. Maybe the Mits can be used in another room.

DLP RP can do medium to dark ambient light rooms but suffer in bright rooms just like what you already have. Due to black levels some small amount of bias lighting is better if you want all the lights off. In that area your CRT has an advantage.

Direct light is always difficult regardless of display type but yes, LCD has an advantage under such conditions due to shear light output.

Nearly all DLP RP used wobulated DMD devices rather than a full pixel matrix to reduce manufacturing cost. For all the concerns we had it worked out pretty good but tic-tac detail is reduced by this system. I have been very satisfied with our 5 year old Samsung wobulated 720p with video content.

Many use DLP RP for PC applications, gamers have no complaints I am aware of and the same can be said of 3D. There are issues with 1:1 pixel mapping and these products do have overscan that you cannot overcome, all inter-related to this facet of imaging. To be clear though, for PC the image is reduced in size, you will see the edges of your desktop, it does function.

Due that I am not overly fond of PC applications for this display technology yet many are satisfied and I have not received one complaint from a user related to this knowledge or my personal concerns.

Thanks, great advice as always.

My MITS is suffering from phosphor burn and uneven wear, due to my lack of willingness to watch the imaged stretched, or worse yet with gray bars on the side. It now has a clear red tinge in the 4:3 section which would probably not be noticable if the bars weren't pristine white when watching Ice Road Truckers! <grin> Of course, I knew what I was doing but some things just can't be helped. Its bad enough that even my wife can see it!

While a b/w tracking adjustment could cure the red in the 4:3 area nothing can be done about the difference between the sides and that area without replacing CRTs which is not going to happen. Considering how obvious it is I would be on your side for replacement.

Good news with DLP is that won't ever be a problem :!:

About what I was thinking. Thanks.
