Panasonic TX-32LZD85 - over processing? (1 Viewer)

[John H Ross]

Well I just took the plunge and upgraded my Panasonic CRT for a Panasonic TX-32LZD85 LCD display.

I'm a little disappointed. Ok, VERY disappointed.

While Blu-Ray performance is first class, the SD pictures upscaled by the Panny are almost totally ruined by what looks like excessive D-NR. Images look as if they're being overly processed. It's affecting everything: DVD, Sky, Freeview (anything that's upscaled).

For example:

Watching a US movie trailer (R1 DVD), the first screen showing the certificate is white on green/red/whatever. The letters are oversharpened and have an incredible amount of MPEG noise around them (creating an unnatural "blocky" text effect). It's doing the same thing to moving images and other on-screen texts (I'm using a Denon 2930 as my upscaler by the way, set to HDMI RGB 1080p, and v1.3a Panasonic HDMI cables)

The Sky menu - the options on the screen "Entertainment", "News", "Movies" etc are all surrounded by MPEG noise.

The sharpness setting on my display is set to NIL and the D-NR is also to OFF.

What's causing this? Is it the discreet 100Hz processing (that can't be turned off) or the extra (unpublicised) DNR that this set is adding without my knowledge on upscaled images, even still ones with no movement? Or is it simply "normal" for SD sources to look like this when they're upscaled to 1080p? Is there any way of reducing it without losing PQ?

Is it a fault with my set? Does anybody else have the problem?

Thanks!

So which is doing the upscaling? The Panny or the Denon? Are you trying both? You didn't say what blu ray player you're using. Have you tried it's upscaling abilities? If not, try each one, and see which does the best job. Don't forget, when trying one, turn off the upscaling of the others, so they don't interfere with each other.

The Denon 2930 is doing the upscaling, to full 1080p. I believe it has a far better upscaler (Silicon Optix Reon) than the Panny.

I'm using a Panasonic BD-50 Blu-Ray player. I believe it's a fairly bad upscaler so I haven't tried it. I specifically need the Denon for DVD purposes because of the seamless layer changes.

A question: Is there actually way of turning off the upscaling on the TV if the player is doing it, or does the TV automatically detect that it's receiving a 1080p signal and doesn't interfere with it in any way?

Sorry, but I don't know.
It should tell you in the owner's manual for the tv.
Hope you get it figured out ok.
Maybe someone with the same tv will come along and help.
Good luck!
