Panasonic TX55HZ1000 PQ issues

I've recently had my 5 year old Pan TX-55CX802B replaced under warranty as spares were not available. It's been replaced with a Pan TX-55HZ1000 OLED.
I was very happy indeed with the 802 until it developed a backlight fault.
The new HZ1000 OLED is sublime on HD/UHD and 4K BR's. However it's not so clever displaying SD content, the 802 was superior in this respect.
Some of the HZ1000 PQ display settings ie Netflix Calibrated/Cinema/Filmmaker modes I've personally found just too dark, in most respects the 802 had a brighter/sharper PQ.
A Panny UMB900 4K player is used.
On a separate note, I've noticed that when any Prime content is paused, there's no streaming info displayed in the bottom black bar of the HZ1000 unlike on the 802 where it showed either 1080p/HD/UHD/or HDR where appropriate...odd...

Any comments appreciated

What picture mode/modes are you using?

I'm surprised to be honest. I had the gz950 and now have the JZ1000.
For me, SD is entirely dependent on the quality / bit rate of the content.
Local news channels etc. look awful, but I played a dvd of casino royale the other day and it looked amazingly good. Sharp, clean, and very well upscaled. But I only ever use Pro1 and Pro2 with no IFC etc.

The JZ1000 is a 2021 model so should be even better. I had planned getting a JZ1500 (when available) prior to the 802 failing, but happy enough with the
warranty replacement HZ1000.
I shall experiment more with the picture settings.
Not tried any DVD's as yet, but BR's especially 4K versions do look superb.

Still confused as why to any SD content is noticeably poorer on the HZ1000 than the 802 ?

I really don't think the JZ will be better, I think it's more to do with them adding some additional hdmi 2.1 features etc.
Have you got any examples of SD content you really find poor? Is this via aerial, sky or something else?
To he honest I very rarely watch any SD at all now.
As you say blurays and 4k blurays etc are really impressive.

I don't watch a lot of SD content apart from Channel 11 and 12 Sky Arts and Quest and some YouTube. Strangely enough for some reason watching some last night the PQ appears to have improved some since I first got the new set.
The TV is connected via aerial, no Sky or anything else.
Plan trying a couple of DVD's that I know we're really excellent on the old 802, very nearly as good as BR's.
Thanks for the suggestions/ideas ....

Yeah I don't think those 2 channels will ever be very good unless they can improve the source. Testing DVDs is a good idea. I'm gradually replacing DVDs with bluray etc. I still think you have a very good TV there 👍

With the prime black bar info you mentioned, have you got some overscan mode going on? This could also make sd content look worse

If your Freeview transmitter broadcasts the COM7 'mux', then Quest HD should be available @ channel 114, along with other HD channels like BBC4 HD and BBC News HD.

If you don't currently have those channels, then a manual tune or 'signal condition' check at UHF channel 55 will show if it's available and your aerial is suitable.

Sadly, the future of those HD channels is currently uncertain. Fingers crossed they can shift things around so we don't lose them !

Em a good question, only one I can find that's ON is 16.9 Overscan - but really don't see much difference with it ON or OFF ?
Makes no difference to the loss of info pausing Prime on the lower
Black Bar.......

Definitely turn overscan off. Leaving it on messes with scaling.

You might, at a push, make an argument for using overscan with SD broadcast content, which it sounds like you watch a lot of, but even then I'd say leave it off. You're losing part of the content as well by zooming in this way. Overscan means essentially adjusting to an incorrect aspect ratio.
