Sky Glass calibrated MEASURED settings

BigBri165 — Wed, 24 Apr 2024 09:38:18 GMT

In a past life I was a THX certified calibration tech. I retrieved my old kit from the loft and thought I would see what I could with my Glass 65".

I will post the settings later but if you want to use them please feel free but remember every set and room is different so they may not work for you.

Things I discovered in no particular order-

It's not possible to set the contrast correctly due to limitations of the panel. Playing with the backlight/contrast settings made no difference. So I measured the light coming out for best measurement.

There are different settings for each picture mode. If you calibrate in HD, these settings will all be reset in HDR or Dolby Vision. This is a GOOD thing. I've yet to calibrate any HDR modes as yet. Will hopefully look at this later today.

The white balance and cms are surprisingly responsive. Changing them does make a difference.

Biggest issue I find is light bleeding into the black bars on a film in the scope aspect. Some of the worst I've seen to be honest and makes watching in darkness impossible. Some ambient light of to each side side hides it a little.

The readings will be posted later when I get home but they did improve the picture as I was getting a green tinge in the lighter colours. Adjusting the white balance with a metre had gotten shot of that.

Still have work to do on it and I don't want to post half cocked results so watch this space.

Measurements for HD/SD as follows:

Auto back-light off

Back-light 75-80. Adjust if you find the image to dark

Aspect ratio auto

HDR/DV pic mode dark

Contrast 46

Sharpness 0

Brightness 51

Colour 55

Hue 50

White balance

RG 12

GG 0

BG -6

RO 18

GO 0

BO -22

Local dimming on

Colour management

Red 51, 61, 0

Green 56, 30, 1

Blue 53, 52, 1

The rest don't change so controls don't work properly.

Its not been remotely possible to get anything like a decent HDR/DV calibration because the screen just isn't good enough.

Anything below 30 and above 70ire have no effect so pointless.

I did find that upping the brightness to 51 revealed a little more shadow detail on my test pattern.

Software used - Chromapure plus

Metre - i1 Pro recently calibrated

Spears and Munsel reference discs for patterns on both.

As I've been commenting since October 2021, it's really unfortunate timing that Glass was specified and manufactured in the depths of the pandemic and its associated global silicon component shortage: to be fair an unforeseen and unavoidable situation but one which wasn't helped when Sky and its design studio chose to use what was presumably a considerable percentage of the total BOM on the bespoke aluminium enclosure rather than increasing the spend on the panel and video chipset.

Can you use the same settings for HDR / DV or should you leave on default settings?

Have you tried BBC iPlayer for the HDR Euro 2024 matches?

I'm wondering if you'd picture is as dark as mine.

Toggles through the presets and not much difference, so it's either the Beeb or the TV itself.

Agreed Red+Silence The euro 2024 coverage in HDR on BBC iPlayer is definitely a fair bit darker than the coverage on the BBC1 HD channel. I therefore haven't watched any coverage in HDR on BBC iPlayer.

Great picture settings mate. I would also like to add that the HDR on my glass, doesn't seem to work at all. All UHD films and sports channels are far to dark to watch without HDR kicking in. The backlight is preset at 100 for UHD already. The option to up that is out and HDR picture mode is bright. So is the Dolby Vision. I can watch a program via an app and the picture is perfect. Reset did nothing either. HD is a lot better though

A silly question for most but the "-" on blue is that because its the last colour or is it + or literally minus as that would take away blue?

Great advice, Thank you. The preset for red was awful. This is much better

Thanks for the settings, Ive got the 65" too. Have you adjusted the settings at all since April or still the same?

Hi there, I've tried these settings on my Sky Glass. It's made a considerable difference to the picture quality. Can't fault it. Thanks for your info 👍

Folks I only kept my Sky Glass for a week. I'm happy that these settings have helped people but I'm unable to answer anything regarding them sorry

Could you do the same with a
