New monitor time, thought I had it sorted but ...

[Chris Noble]

Any reasons for choosing the Proart PA329CRV over the PA239CV?

I'm interested in both.

BobKnDP and CAcreeks,

Thanks for your inputs.
Per this bhphotovideo comparison chart , the differences between the PA329CRV and the PA329CV are:

- - - - - - - - - - -

Dynamic Contrast Ratio:
CV=100,000,000:1
CRV=3000:1

- - - - - - - - - - -

Googling, for any monitor some say that the "Dynamic contrast ratio" is a bogus number. But still, is 100,000,000:1 worthy of consideration compared to 3000:1?

It's only relevant for watching video. Adjusts the panel backlight periodically, depending on how bright the overall image is.

"Use my settings" has always been turned on, and the profiling software (Calibrite Profiler or DisplayCal) had worked properly in the past.

The auto color management is the new thing that messed up profiling.

BobKnDP, it appears you are correct that Automatically manage color is a new W11 feature. Found a Reddit thread about it:

For an opposing viewpoint:

Thanks for the links. I wish I'd found the Reddit one months ago. (Although it's beyond my level of understanding.) It's listed as from "1 year ago", but it seems to still apply.

I'm unclear on how new the ACM feature is in released versions of Win11. 24H2 may have enabled it by default.

(snip)

An additional detail: I checked my secondary (Intel) system. ACM messed up profiling on it as well. Disabling ACM restored things.

I'm a little surprised that there hasn't been more online hollerin' about the issue, if 24H2 enables ACM by default.

FWIW, when asked, "on windows 11 24h2, is auto color management enabled by default?"

Copilot says:

"No, Auto Color Management is not enabled by default on Windows 11 24H2."

I don't have a fresh 24H2 install to look at, so IDK. What have others found?

I installed 24H2 and it's on. Don't know if it was off before. It does not interfere with my profile. Not exactly clear what it does.

I can't answer that for certain. I believe that it was enabled by default, but maybe I made an error and enabled it. Gotta have the latest and greatest, ya know.

Oddly, this is what I get using Copilot:

Does Windows 11 24h2 enable automatic color management by default?

Yes, Windows 11 24H2 does enable automatic color management by default. This feature, known as Auto Color Management (ACM), provides system-level color management to ensure that colors across Windows apps appear accurately and consistently on supported displays. It's designed to improve color quality, even on displays that only support 8-bit color1.

Bizarre!

Conveniently, I was offered 24H2 on this, my primary drive, about an hour ago; just installed.

ACM is *not* enabled! How weird is this, where some of us are getting 24H2 enabled, while others are not?

So at this point I'm at a loss to figure out what's going on. I see some other changes to my setup post-update, so I'll be busy today. After lunch, that is.

I've found Copilot to give unreliable answers to technical questions. Bad enough that I wouldn't recommend it to a trusting user.

Even when it gives accurate answers, it's less useful than I hoped. When asked about the monitor profiling issue, it did an OK job of finding my own posts. Unhelpful.

Appears it will be a non issue for my uses. Thanks for your follow up!

I'd say that about the Internet in general. Plenty of unreliable technical answers here/there, IMO.

Even when it gives accurate answers, it's less useful than I hoped. When asked about the monitor profiling issue, it did an OK job of finding my own posts. Unhelpful.

I've gotten into the habit of asking the exact same question on both Copilot and ChatGPT. And when they disagree, as I've seen them do, then I'll do a general web search and hope to find something resembling a consensus.

They've given that the 'cute' name of hallucinations. Copilot and chat gpt just make up stuff.

I've read from a number of sources that since IA was incorporated into google search it has delivered worse results.

I rarely see stuff that's entirely made up.

But a lot of it might as well have been.

No they don't. What happens is that sometimes their analysis engine gets stuck by misleading word patterns that send them down a blind alley. Machines that have bugs are not malevolent.

I've read from a number of sources that since IA was incorporated into google search it has delivered worse results.

Google Search has not changed. What they did is put a response to your query from Gemini (Google's AI) ahead of the Search response list. You can ignore it. I've found it pretty useful more times than not.

I didn't write entirely. All good hallucinations start with a kernel of the truth.

Big. Really big. Small text.

The default setting seemed yellowish/warm until I looked back at the old monitor. The old one has a very greyish blue cast.

I need to put together some sort of temporary stand to get the two monitors side by each for a better comparison, but looking at the same image on both monitors, things look much much nicer on the new one even though it is over a foot further away right now.

Oh, and did I mention, big.
