Been a VT25 owner for a while now and was always on the fence about if calibration would be worth it, but decided to give it a go - I was 90% happy with this TV from the start, but never could get certain things to look as good as I thought they should to me.
I got a 65VT25 last October, and my first impression was the picture had a sort of...greenish tint to it (especially skin tones). I applied D-Nice's offsets, and that made a world of difference and gave me a picture I've been fairly happy with after calibrating with first the Avia DVD, and more recently Disney's World of Wonder (WOW). Both of those did a pretty decent job, but I still felt certain things seemed a bit...dark (especially an old PS2 I have hooked up - yes; I play PS2 games still, since I always wanted to play the Kingdom Hearts series and never did. =oP), and try as I might I couldn't seem to get things to look quite the way I thought they should. There was nothing obvious - I could see all the detail, but it just didn't look quite right to me - sometimes things appeared a little dark, while other things seemed beautiful, and adjustments never seemed to totally fix that.
So I finally decided to go ahead and get a professional calibration done, and boy am I glad I did! I went with ChadB (HDTVbyChadB.com
), and he did an incredible job!
He was very friendly, didn't mind questions at all, was very professional, and most of all took the time to do it right and didn't rush, explaining everything as he went (very interesting to a techie like me) and even providing all the before/after graphs and a list of all the changed settings (including service menu ones) in case I ever need to restore them. I couldn't have asked for more (and hope to get him back to do a sound calibration in the near future).
I honestly was a bit worried since I'd used the calibration discs, I wouldn't see much difference, but the change is quite extraordinary, and he definitely gets into a lot of settings and tests that a disc simply can't provide. The picture just has more pop all around, and scenes where I felt the picture was too dingy are no longer an issue - the PS2 looks much, much nicer as well - more along the lines of what I'd expect from a CRT, and things don't look as drab/washed out.
He calibrated the 3D as well using his equipment and my glasses, and that's seen dramatic improvements as well, especially in pop and accurate color.
My advice is, if you're considering a calibration but on the fence, you won't be disappointed in getting one, especially if you don't feel you're seeing everything the way it should look like I felt for a while. I know there are several highly respected calibrators on here who I'm sure you wouldn't go wrong with, but if you're in the area he services, I can't speak highly enough of ChadB.
Now, back to enjoying my TV. =oP
