Sony A9 Master Series KE48A9 OLED winging its way to Marco Towers!

[Macca]

Which of these images is correctly colour calibrated? Top, middle or bottom?

white balance is best in middle

That's not what you said in another thread: https://theartofsound.net/forum/show...ation+download (post 12 et seq.).

Given the cost of my Sony TV, any improvement gained through using a calibration service would be minimal and wouldn't justify the expense.

Were I to spend £1,500 or so on a larger sized OLED screen, then having it calibrated would make more sense.

Indeed, which is the position I'm now in, but wasn't before when I made that post in 2018

Quite simply, the better the TV you've got, the more it warrants getting the most out of it - and btw, this particular Sony is STUNNING!

I set it up last night using the YT video I posted earlier, and that gave a notable improvement in all areas, particularly in terms of sorting out brightness and black & whites. However, the difference between this OLED and the previous Sony I had, which was pretty impressive on its own, is really night and day.

I'd say like going from using a pair of £1000 speakers, to £3000 speakers, or more - a BIG (a very noticeable) jump in performance, in this case just sheer resolution/definition and clarity - *especially* with 4K HDR Blu-rays, which now really come into their own!!

Yes, I'd agree, but it's really guesswork when viewing the image on a computer screen.

Btw, not sure about on your TV or Martin's, but there's a whole section on this Sony, under 'Expert' settings (a level above of Advanced), full of all manner of controls in terms of adjusting the colour balance and black and white levels, which is designed for use by a calibration engineer.

There's simply no way you'd be able to optimise the settings by eye - and that's an area I'll be investigating in due course, with my local friendly engineer!

Can one say? Cameras and associated programmes will give different results even on 'default' settings, so images will vary regardless of monitors or TVs.

Correct.

Top is obviously too warm, bottom one could be right except you can see the clouds above the hills in the background are better defined on the middle one, bottom is marginally 'too cold.'

I agree that the optimal way to calibrate is to get in a bloke with a spectroradiometer to do it but it's not worth £300 to me. I would certainly do it if I was setting up a dedicated home cinema room with a projector or 200'' screen, at that level you might as well get it perfect and the cost is then is only a tiny fraction of the overall spend.

Yes. There's an industry standard for calibration called D65 - https://www.waveformlighting.com/col...is-it-used-for

Yes, but no-one's asking you to do it, daftee, are they, so why are you harping on about it?

I'm talking about ME, not you. The way you're going on, it sounds like you're begrudging me from doing it, as if you think I'm daft, or have I got that wrong?

If so, perhaps both Barry and you could simply say, 'Go for it Marco, if you want, as with your TV it makes more sense than doing it with ours', rather than instead what's coming across as being keen to piss on my parade.

Just sayin...

sorry didn't realise I was 'harping on' about it. You brought it up as a subject of discussion. Obviously there's a cost/benefit consideration with something like this which I simply mentioned in passing.

I'm neither encouraging nor discouraging you to do it.

In fact I thought you'd already done it.

[Marco]

Nope, not yet. But yes, since I've mentioned the subject of professional calibration, you and Barry have been in the 'Bah Humbug' camp, whereas Gaz has been the opposite, and given that he's both done it to his own TV, and owns an OLED (a better one that mine), I think I'll follow his advice, not that of the grumps!

So.... Let's see more positivity, on the subject of professional calibration, than negativity, and niggling about the cost. I'm spending my money, not yours!
