This evening, I attended an event at a local dealer, and one of the displays was a JVC X70. I brought my Blu-ray disc of Casablanca
, and I had an opportunity to play it on the X70. We immediately noticed that the upper right corner of the image had a purplish tint to it. It was pretty apparent. When we put some color content back on, it wasn't so obvious, but in scenes with blue sky, you could see the tinge.
Has anybody else seen a problem like this on the 95ES? Do you guys watch black and white classics?
All LCD, LCOS, and SXRD displays have inherently imperfect color uniformity. The degree of imperfections can vary greatly between models, and even between different units of the same model.
I watch a lot of B&W and am very sensitive to this issue. Color uniformity problems which would never be noticed in color images can be very distracting with B&W images. I have owned four projectors and demoed four others. My Sony 10HT and HS-51 had quite distracting color uniformity issues. My VW50 (Pearl) was quite good and rarely distracting. I have a new VW95 which is far superior in color shading to the Pearl. My 95 is almost perfect in this area, and even with the most revealing images, I have to look very hard to notice any imperfections.
If you watch a lot of B&W, it is very important that you demo using B&W material or revealing test patterns. Also, if you buy an LCD, LCOS, or SXRD unit, test it with B&W material as soon as you receive it. Individual units can vary widely.
