    Hi !

    I'm living in Canada and received my new TV ( a sony KV32HS500) two weeks ago. I really enjoy the picture quality... after about 100 hours of continuous running in pro mode, i have calibrated it using AVIA... color decoder was adjusted successfully ( take care of the green saturation and tint after that, they were too low for me )
    I choose this TV because i had the opportunity to have a samsung HDTV for a couple of weeks and felt in love with line doubling, and flat screen, and... etc... i choose the Sony because the 3D comb filter works better on digital cable box and because the pixels are smaller than the one on the 2 sides of the samsung's screen.

    well, that's for the story...

    my questions are about the DRC of the Sony set... when watching my non progressive scan DVD player on the samsung, i was noticing artifacts. i was thinking that it was because the samsung was lacking of 3:2 pull down... but digital cable box was perfect and there was nothing wrong in 30fps based films...
    on my new sony :

    - i can notice strong distortion of vertical scrolling text in progressive and cinemotion modes and NOT in 960i (Interlaced) especially when the text is white and when using svideo or composite or components inputs...

    - i can notice strong lines separation in pure colors and especially in Red.. making the picture looks like it was filmed in 320*200 with an anti-aliasing made for 1600*1200... (chapter 13 of star wars I, about 15 seconds after the index, one can see the inside with a red background : can you see that ?)

    - horizontal artifacts (black lines or color lines) appears when there is a lot of action, and moving frames... EVEN in CINEMOTION and when using composite, svideo or component input(it becomes hard to notice here)


    i analysed what is happening and it seems to be like if the line doubler was saving impair lines and keeping them on screen while saving pair ones to make a progressive picture, BUT was releasing impair one too late for the next picture coming : resulting in a superposition...

    Am I right to say that i have a trouble ? i think that the DRC on this model is not the first one sony makes... i think it is unacceptable from a tv i have paid 2900 CA$ with the extended warranty... i don't have the place for a RPTV but for the price i could have had a great RPTV...

    Thanks for reading me.. i hope that i am the only ne to have troubles... cause i do not want to say that sony is producing lemon TV... it must be a tweak to fix this DRC trouble...

    Ahhhh !!!!! yes there are two : using a progressive scan DVD player because the DRC is disconnected in 480p like the seller said... and having my graphic card checked in the digital cable box.... but all was working fine with the samsung....


    thanks and feel free to answer...

    Yann

    I've read that the DRC isn't exactly the best line doubler, but that's just a general impression I've gotten from forum posts and I've never owned one myself.

    It looks OK to me, but not as good as progressive DVD.

    Do you have SVM off and sharpness all the way down?

    There's an explanation on the hometheaterspot Sony forum on how DRC operates.
    In summary: Use Interlaced for video based sources, Progressive for stills, and Cinemotion for 3:2 pulldown on film based source.
    Interlaced is 960i and does a pretty good job at removing visible scan line structure. The Sony with a 480i ntsc input with DRC looked as good as some other sets at 1080i[​IMG]

    hi!

    a good news for me :

    it's now working well... it was my DVD player....
    on this set, take care of A/D conversion...
    i have changed it for a new JVC with 10bits / 54MHzh conversion and NO TROUBLES... in 480i or 480p


    Sorry for my reaction....
