    I was lucky enough to get a visit today from Gregg Loewen and Ned Vogler. Besides having fun Discussing HT and Movies Gregg Came to Calibrate my Mits 65807. He was very meticulous the whole calibration took about 7 1/2 hours. First he worked Disabling SVM, then he started on my Progressive DVD input, adjusting Convergence,overscan, Greyscale and front Service menu adjustments.
    Then he did the same for my Hi Def input. I was in awe watching him work. My Hi Def Greyscale was way out there. I don't know how anyone could get a full calibration in an hour and a half. It takes a bit to tweak these things. After getting everything to 6500 across the board, we proceeded to remove the screen and add Lens Striping. My set really benefited from this tweak. On the left side of the screen it had measured 9400 degrees to the lefts 6400.
    He was able to get the left down to around 7200 when he was done and the difference was noticible.
    I will say that anyone that's bee watching their set's without a greyscale adjustment willnotice a big difference. Colors are more accurate and even. Hot Spots on the screen are non existant. At first the picture will appear soft, it definately did to me. But then subtle details will come thru, blacks and variations and shades of blacks will become apparant. Details once missing in the dark areas will become exposed. I'm still adjusting to the picture but I'm liking what I'm seeing. I'd recommend Gregg to anyone thinking of having their set Calibrated, Of course he learnt from Micheal TLV so he comes from good stock. he's even putting together a before after chart of the results.
    Thanks Gregg and Ned

    How do I find someone in Virginia?
    I might be moving within the next 6 months. I should probably wait though...moving my Tosh after adjusting it probably would throw it all out again.

    Moving the set shouldn't affect the standard ISF calibration (grayscale, lens striping, etc.), but you'll probably need to redo convergence after you move.
    Good to see that Gregg has joined the ISF fold. Obi-Wan, er, Michael TLV has taught him well in the ways of the Force... [​IMG]

    Great, I can now (having met both Gregg and Michael) hear Gregg saying "Last time we met I was the learner...now I am the master..." [​IMG]

    For all that are interested, here are the pre and post calibration results. I set gray scale for both 480P and 1080i and took measurements before and after. In case you are wondering, premeasurements were performed before any work was done on the set, with the exception of front panel adjustments via Video Essentials (for 480) and the Accupel HD Signal Generator for 1080i. I also performed lense stripping on this set. After calibration there was a 2900 degree difference from left to right. After stripping there was a 1000 degree difference. The difference was definitely noticeable to the eye of David, Ned, and myself.

    Gregg will be in my town this weekend to work on my Tosh 40H80 and two friends' TW40X81s. I'll be sure to follow up with the results here!
    Gregg: glad to see you have some happy fans out there!

    Well its done, Gregg did a great job calibrating mine and two others' RPTVs. The first one I witnessed, a TW40X81, underwent a transformation from a fine looking display to truly excellent. I then watched him calibrate my 40H80 and another TW40X81. Gregg really cares about what he is doing and takes the time to make your display as good as he can make it. I highly recommend his services.

    Yes, I totally agree with Marc. I also watched Gregg calibrate the first T.V. (mine) and the last one. Truly a startling difference from the out-of-the-box experience. I highly recommend anyone who's anal about video quality (most of the people here, I'm sure [​IMG] to have this done. It's well worth the money.
    -Steve.

    I Agree We were all Pigging out on Chicken Wings and Gregg would'nt eat till he overcame a particularly tricky setting giving him trouble. He's dedicated to doing the best he can and getting the Greyscale as close to 6500 as possible. He does an excellent job.

    Speaking of getting close to 6500K, here's some pre and post-calibration stats from my Tosh TW40X81 that Gregg calibrated, complete with a nifty graph:
