Απάντηση: Νεος HD D-ILA απο την JVC (RS-1)!
Στρατηγέ μου το είδες αυτό; Κοίτα τι γράφει ο Greg Rogers στο αμερικάνικο forum! Πιστεύω ότι αυτό εξηγεί τα πάντα και διαλύει και τις τελευταίες ανησυχίες, αρκεί βέβαια η JVC να λύσει το πρόβλημα με κάποιο firmware upgrade…
First, let me provide a quick update on the behavior of the color issue. I found last night that the color matrix mismatching (listed in the first post of this thread) can change from one power up to another. The digital RGB problem shifted from HD to SD signals when I powered up the projector last night. That wasn't very surprising since this is a firmware issue, which is why I continued to check it when I needed to turn the projector off and on again.
More importantly, I was notified this morning that JVC engineers in Japan have identified the cause (firmware bug) of the matrix mismatch problem. They will give me an update on Monday. I suspect the firmware can be updated through the RS-232 port on the rear of the projector, but I won't know that for sure until next week.
In answer to your first question, I consider a color matrix mismatch to be significant. It is primarily visible as green color that is either too light or too dark depending on which matrix mismatch occurs, and it also affects the hue and lightness of other colors to a lessor degree. But I am extremely sensitive and concerned about color accuracy. I'm sure there are many viewers that would not notice the inaccuracy. However, some will, and that is the reason I posted information about the issue prior to publishing my review. So for now, just avoid using analog or digital RGB signals if you want the best color accuracy, and JVC should have this corrected soon.
