I just purchased my first HD TV, the Samsung LNS4092D. While I'm generally very happy with its image, I do notice that when broadcasting certain signals, dark areas appear very blotchy. For example, the other evening I was watching "Marathon Man" and was very disappointed in the picture when the movie displayed darker scenes. It wasn't that the blacks were so much milky, but square-ish and blotchy. BTW, my television is connected to the cable box via HDMI to DVI cable. Would component connections be preferable?

I'm also noticed that when viewing printed material (like the FBI warning that opens all videos), the type seems to burn itself in momentarily into the incoming scene. This despite a new Samsung DVD player with an upconverter and HDMI interface.

Conversely, when viewing HD content, everything looks amazing all the time.

My question is: 1) is what I'm seeing consistent with LCD technology?; 2) do I have a bad television?; 3) are these problems less apparent (or non-existent) with a plasma set?

Thanks very much in advance to all responders.

If they are larger squares or macroblocks, that would be source compression issues that are becoming visible, and may not be due to your display at all. LCDs can also so some unpleasant artifacting near black, but it wouldn't be larger macroblocking, usually.

Try turning your sharpness down to 0. It helped on mine, maybe it will on yours.

We have the same TV. try these settings Backlight on low energy savings, contrast on 79, brightness at 84, color at 29, on movie settings. should improve with dvd viewing a lot. SD can vary in brightness but for the most part passable.

Thanks one and all for your suggestions. BTW, I did turn down sharpness, which does help w/ artifacting. Will also try the above settings from Rhegaana. Last night watched "Capote" on DVD (excellent movie), which looked great in all respects.

Lastly, great forum!

Scott

P.S. One question still remans; is compression artifacting less apparent w/ plasma?
