I'd appreciate your advice on this:

A local art gallery asked me if they could show a video installation I did with a friend some years ago. Nothing special, 4:3 standard format, easily transferred to DVD.

The gallery has a number of both plasma and LCD displays, but they are all 16:9 which gives a rather small image when you run 4:3 source material. There is no space to mount a video projector in the hallway where the video is to be shown.

Now a friend of mine has offered his Toshiba model 43VJ22P rear projection TV set, which has a large 4:3 screen. It is a few years old but has been used only for about 150 hours up to now. Image quality is a bit rough, but this should be no problem with the source material.

Here's my question:
The gallery would like to run the video 24/7 for three months - do you think that will be OK with the Toshiba set or do you see any problems?

Rear projection TV's use bulbs that have finite lifetimes, which can be expensive to replace as well.

I suggest finding out how many hours the current bulb has on it, what the rated life of the bulb is, and how much it will cost (and how long it will take) to replace it.

Most of them need to be ordered, so you will have some lead time to consider if/when you blow the bulb. The bulb for most projection sets cost anywhere between $200 - $400 each, depending on the model.

Unless it's really unacceptable to have the video run on the gallery's monitors, I'd go that route myself.
