A while ago I used to own a Hitachi CRT RPTV. If for nothing else, I really loved this set for exceptional depth of the picture, at times bordering the impression of wearing those blue/red 3D glasses.

Unfortunately not many displays offer this level of depth. But a few days ago one of displays in BestBuy caught my attention - Philips 50" plasma (the model with that "ambilight"??). None of other displays in any technology that were also showing the same crappy HD material (crappy because there was an awful amount of noise in the HD probably due to really bad cabling inside the store) come anywhere close to this and smaller 42" Philips. The underwater scenes with sharks and other fish were not just gorgeous but very 3 dimensional - it felt as if those two display were windows in the submarine I was looking through. Philips displays also seemed to have a lot less pixellation compared to others. Perhaps these two factors are interrelated. Pana plasmas (50" and 42") and Mitsu DLP were trailing Philips in that respect. While other sets looked a lot "flatter" despite having rich colors, etc.

I kept wondering what properties of these Philips displays add so much depth to the picture? Is that the famous PixelPLus post-processing technology??? Or any other screen/picture properties?

Sound & Vision magazine Nov 2004 issue page 53 published a positive review of the Philips 42 inch Ambilight Plasma HDTV monitor 42PF9966

They said its "performance makes it stand out from the crowd" and they said the " Ambilight system was more than a gimmick when used correctly it's a picture enhancing feature that's long overdue"

Although there ARE quality differences between displays, the fact that the signal being fed into these sets was so bad means it is likely also the case the folks in the store haven't taken the time to set up any of the displays properly either.

What you were likely seeing was that the Philips happened, purely by accident, to be running at closer to proper, calibrated levels.

Mis-setting the display will lead to loss of white and black details as well as proper color balance, all of which provide the subtle clues to the eye which make an image look more natural. It is often the case that the factory defaults for displays out of the box are grossly wrong, being set overly bright/contrasty, overly red, and overly sharpness processed in an effort to lure shoppers to them much like the bright flashing lights on a slot machine.

markrubin,

Whatever the true value of Philips' "ambilight" the odds you can actually even see it in the garish lighting of a typical store setting are pretty small.

I think that inky blacks and excellent shadow detail reproduction contribute the most to the 3-dimensionality of the image.

Well, the "ambilight" on that particular 50" Philips that stood out from the rest of displays was not even turned on. The smaller 42" model was indeed placed inside a plastic "cave" to show off the "ambilight" feature. So, ambilight was not a contributing factor here at all.
