I am looking at replacing my old Sony VPL-VW40 1080p projector with one of the UST projectors on the market. I know they recommend an ALR screen but buying a $1000 -$4000 screen as well is not in the budget right now.

Do the STP produce a good picture on the standard grey screen?

If you have the space, there is not a UST projector on the market which will produce a better image than what your current model projects.

They will be brighter (yes), but of significantly lower image quality overall.

ALR screens are not required for any projector. That's a common myth.

I understand that the Sony VPL-VW40 is a 12-year-old model that sold for $3K which was less than some of the UST models now. Could you please explain why none of the new UST projectors would be as good as that one?

UST projectors have a significantly higher cost ratio due to the type of lens which is used. Many of them are also using a solid-state light source. These two things add cost, without actually improving image quality. In fact, ultra short throw lenses actually aren't nearly as easy to make as standard throw lenses, so you typically end up with a lens which isn't as sharp as what you will get on a quality standard throw projector.

Now, to top that off, the newest batch of DLP chips is not an actual improvement in terms of image quality compared to the previous generation. They have gotten higher resolution with 4K projection, but have a drop off in contrast. Contrast is actually more important than resolution, so this is a net equal overall. Some things will look better with these 4K DLP chips compared to the previous generation of 1080p DLP chips.

But, it is still DLP. Sony used LCoS (SXRD) technology on the VW40 projector. The base technology of LCoS produces far greater contrast than DLP has ever achieved in a single chip design. It also has greater pixel fill for a smoother image. DLP can be sharper, but without the contrast, won't look better for general movie viewing.

Now, screen size does play into this a bit, especially if the Sony is really dim on the current setup.

But, if the image size is about 100" to 120" diagonal, and someone is looking to actually upgrade, then the best route would be to get a JVC RS440/X590 or similar model. The standard throw will give a sharper image than UST models will deliver, and instead of buying a new screen (for no reason) you get a better projector that delivers the goods across the board.

This is interesting but also confusing, because I came here from Projector Central which currently lists the Optoma P1 as the "number one" projector under $10K.

What about the no.3 on that list, Sony VPL-VW295ES, how does that compare to the old VPL-VW40?
