Hi, I managed to purchase the 40” GX800 TV today from John Lewis.

In the middle of setting this up on my wall.

Really like the design and look of this.

Will post my thoughts and impressions on how this performs on games and films very soon.

Gaming on the PS4 PRO seems to be very smooth. I tend to put the picture on dynamic setting for this as it really shows off the HDR.

This morning I connected my Apple 4K TV box to this TV to try out Dolby Vision HDR.

There are three options to choose from vivid, bright and dark.

The pics below are from Jurassic World 2, taken when on the bright Dolby setting.

Picture quality was excellent despite this being streamed and black levels were very good obviously not oled quality but more than adequate.

I bought one a couple week ago. Love it. Can't wait for it to be calibrated, mind!
There's some settings to try here from a dutch review linked by desinho in the other thread.

The best choice starts from the Cinema Pro mode.

Statue Statue Advanced settings
Image mode: True Cinema


Backlight: 20-80 *
Contrast: 90
Brightness: 0
Color: 50
Tint: 0
Sharpness: 30
Heat Color: Warm2
Vivid Colors: Off
Adaptive Backlight control: Min

Ambient Sensor: Off (On) *
Noise Reduction: Min *
MPEG remaster: Min *
Remasteren Resolution: Middle
Dynamic Remaster Range: Off
Intelligent Frame Creation: *
Sharp movements: Off Contrast control: Off / Auto *
Gamma: 2.4 Image settings / 16: 9 Image scan: Off
Main settings;

  • The True Cinema setting provides the best start, but is quite dark. No problem if you look at full eclipse, but for most people it will not hurt to bring the Backlight to a minimum of 40 and in a typical living room even to 60 or 80.
  • You can activate the light sensor if necessary, then set the background lighting to 80.
  • Noise Reduction and MPEG remastering were kept to a minimum. A higher setting is recommended if you defy a bad source (old DVDs or low quality YouTube).
  • Intelligent Frame Creation: Out for purists, but the Middle mode gave extra detail, and smooth images without obvious artifacts.
  • Advanced, you can set Contrast control to Auto for a slight boost in contrast.
  • For a slightly more edited image, but still very true to nature, select the Cinema setting. Set 'Warmte Color' to Warm2, and take the above recommendations into account.

Aquaman movie pic in Dolby Vision.

Showing the three different picture presets.

Which one of these presets you think looks better?

To me vivid looks nice and bright but I’m not an av savvy.

Hard to tell from those images, at least on my monitor tbh. The vivid mode is the most striking (as you'd expect I guess). The blacks look impressive on the borders though, to these untrained eye's.

I had to set the adaptive backlight control setting to max to get better blacks when watching films with black borders as this helps.

I agree vivid mode for dolby hdr stands out the most.

Can someone who owns one of these sets confirm how you attach the pedestal? Is it fitted while the TV is upright or do you have to lay the TV down flat on its front to attach?

And has anyone who owns of these compared it with an FX750 set?

Hey fellow owner here, thanks for this thread. What's the best balance to make the picture not too dark? I like the blacks but the picture seems really dark to me. I have RGB range set to normal in game mode which gives you good blacks but it seems almost too dark due to the depth. I have the light sensors off & stuff. The motion isn't great from my experience, I've noticed a lot of judder. If it was smoother it'd be better all round. And HDR seems to wash out the blacks when I enable it unless I'm doing something wrong?. I feel like there's a lot of potential to get a satisfactory picture here so it'd be ashame to return it :blush:. i tried Warm2 but it's too orange. Mpeg remaster, noise reduction & Intelligence frame seems to have made a significant difference to the smoothness though.

You can do it while it is upright, I don't own but I do see them every day, I personally think the 800 is better than the 750, but if you need freesat built in, the 750 is the model to buy.

Does anyone on here own the Currys/PC World exclusive TX-50GX820B model?

From what I can see from the Panasonic UK website, the only difference between the 820 and the 800 is that the BMR is higher on the 820 (1800) vs the 800 (1600). Although the Currys website seems to contradict that, showing 1600 for BMR on the 820.

Are there any other differences? Would I really notice the difference between them?

I watch mainly Freesat and Blu-Ray/4K UHD discs, and the odd bit of Xbox One X gaming...

Thanks for this, I don't have space in the lounge to lay the thing flat unless I lay it on the floor and I'm not overly keen on doing that! Freesat built-in is not the be-all-and-end all by any stretch, but it does mean less clutter on the bottom part of the AV rack (Netgear network switch, Xbox 360 and Xbox One X then adding a Humax box if I go for the GX800!).

May I ask, what is it that you feel makes the GX800 better than the 750? VA Panel as opposed to IPS? Dolby Vision? Anything else?

Would be a significant difference between this & the GX900 in regards to things like motion?. I'm not sure if that'd be worth the extra several hundred

The only difference between the two models is that the GX820 has picture and picture (PAP) mode, which means you can display two different AV outputs on the same screen, the refresh rate is the same on both models 1600.

There is no GX900 model planned for the UK.

There is the GX920 model but this comes in one size only 75".

The picture is definitely better on the GX800 in terms of contrast.

I do miss the dual tuners on the FX750 but you'll get used to it. Everything else seems the same to me.

The TV itself looks better too I really didn't like the design of the FX750 and it was really heavy probably because of all that glass going around the frame.

OK so a mistake regarding the refresh rate for the FX820 model on the Panasonic site.

I would use only the Freesat tuner on the FX750B if I had one, as the Freeview reception where I live is non-existent and isn't worth the cost of getting the aerial fixed or a new one as I have Sky satellite dish already, but canned Sky last year.

I must admit I am now leaning very much more towards the TX-50GX800B set now...

Enabling MPEG Remaster & Noise reduction is an absolute must for freeview HD content & on demand like ITV Hub. It makes a significant difference to the smoothness of the picture, without it there's lots of choppy frames. Same with intelligent frames creation but thats not available for on demand content.

For some reason these options are unavailable for game mode which is ridiculous. The best we have for gaming is clear motion which only serves to make the picture worse. PS3 quality is a mess on this tv due to the 50hz refresh rate. I played God of war ascension & all I could see was wavy lines everywhere. PS4 of course looks smoother as the games support higher frame rates & resolution but I can still see some motion issues.

I also think the HDMI Black level makes the games either too dark on normal (due to the depth of the blacks) or too washed out on the other setting. Normal setting is clearly the way to go but is their a way to make the games appear not as dark?. I'd appreciate full settings for gaming if anyone has some :).

Ah thanks for the heads up, that explains why John Lewis haven't got it in stock.

I prefer the overall Pq on the VA panels, blacks are better, and the colors look more natural IMO, I've tested Altered Carbon on Netflix in DV which looked really good, some nice dark scenes with really bright lighting going on.

I am after a small quality TV for the bedroom. I currently have the 55cx802b in living room and it is still better then most the TVs (non OLED) around today. The build etc is excellent with top end panasonic Tv's and I can see that finally they have what appears to be an excellent 40 inch 4K TV. I saw the 50 inch in Richer Sounds yesterday and the unit looks class with the pretruding glass and very slim design. As far as I know the 40 inch panels are VA only (although £650 for a 40 inch is TV steep) but unfortunately I have a wife you won't let me go any bigger than a 43 but all the 43 seem to have a panel lottery. I was in the process of buying a Samsung 43NU7400 but I didn't want an IPS panel having had a quality VA panel for many years. Can any owners please let me know their thoughts re build and screen? If anyone could please confirm these are VA only that would also be appreciated :)

Build and screen quality of this TV is top notch, very solid and yes the 40" is using a VA panel.
