FWIW, in reviewing the LT150, LP350, and XP21N, I felt the LT150 won in both black level and contrast.

arrow,


How did you find the LT150's "Vortex" video-processing capabilities in comparison to the LP350?

rlsmith,


I reviewed the LT155 not the LT150. It had Vortex processing.


I don't think Vortex has 3:2 pull down detection. If there was no motion in a movie, it weaved pretty good. But when motion came up, it appeared that some frames would be weaved and others would be bobbed.


It looked o.k. but a computer really improved the image.

I would also like to point out that at the Infocomm show, the 2 colorwheel manufacturers that I saw were making colorwheels with much smaller clear sections than I have seen in the past.


Whereas in the past, the clear section could be as large as 22% of the entire wheel area. Every colorwheel I saw at the show had clear sections no larger than maybe 15% and some had no clear section at all.


This is a very good sign. The smaller these clearsections get the richer the colors are going to be. I wish I had seen the LT150z at the show. I was too busy looking at NEC's big stuff and plasmas.

i was under the impression that the vortex technology already existed in the lt150 and lt85, as well as the ability to store a presentation on the projector.

Doh! 'Z' is for 'ZOOM' . . . .

I just don't understand that why NEC do not incorperate DVI interface in the new LT150z which has already in LT156!

rlsmith,


I never really got to testing the internal processor. I was short on time so I took Grant's word for it that the internal processor was poor and put that part at the bottom of the eval list.


I did try S-Vid in once so that I could test native mode. Surprisingly I remember True Lies (Helicopter Scene) looking pretty comparable to LP350. But I didn't get a chance to look in detail, so I don't want to draw any conclusions.


So, is that what VORTEX is, a scaler? In another thread I actually wondered aloud whether VORTEX was anything more than creative marketing. Has anyone visually compared the NEC against the PLUS it's based on?

"Has anyone visually compared the NEC against the PLUS it's based on?"


IIRC, it's the same light engine as the Plus U3-880, which was reported to have much poorer color rendition.
