Fair point :) I should reconsider. The UltraSharp line is factory calibrated but yea that doesn't mean much as it varies between display.

View on HN

It is factory calibrated for general desktop usage, but not necessarily for photograph reproduction.

Buy the cheapest Datacolor Spyder5(S5X100). The hardware is same between all the versions and only the software differs. Then get the open source DisplayCAL(https://displaycal.net/) that works with Datacolor sensors and other manufacturers. I calibrate my display once or twice a year. I also use it to calibrate my gaming computer and laptop.

I use the Open Source Hardware colorhug and it works with DisplayCAL

If you are also printing than you need to spend more money on a calibrator that works with both screens and printers.

I can't tell you how huge the difference can be even on high end monitors. I had a friend that swore all Macs were calibrated and he got mad at me when I laughed. After we did the calibration he realized how wrong he was.

Also buy this: SpyderCHECKR 24 and use it as the first picture at any new site. Color correction within 10 seconds.

I used to work at Datacolor, and I specifically worked on Spyder and SpyderCHECKR. It's nice to see that those get lots of love when it comes to color calibration :) but it still amuses me that they haven't figured out how to deal with the fact that their high-end Spyder unit sales are getting supplanted by the open source color calibration libraries..

Shhhh don't let them know. Funny thing is that Professional Shops and video companies are really starting to embrace these open source libraries.

So what is your thought on the Color Hug 2? http://www.hughski.com/colorhug2.html

I bought the first color hug and it is still serving me well but I really like the new color hug 2 especially the latency tool.

Oh, I haven't worked there for a few years, but someone I know already brought it to the attention of upper management(pointing out the fact that Amazon reviews for Spyder products literally tell people to use the Open Source libs) and they've basically just ignored it as a whole. Their products are cool, and there were a few great people, but the company itself was... I won't really go further into it. Alas, I haven't been involved in imaging in quite sometime so I can't really comment on Color Hug :/

Or you can do it manually the old way with a colour reference sheet. More laborious and requires good lighting (preferably daylight).

Well, it's calibrated to a specific delta-E so the amount of variation is limited - in practice, unless you're in a room with controlled lighting and are doing professional work (neither of which seem to be the case) calibration doesn't really matter.

(I went with an LG 32UD99 w/ some similar criteria of decent content creation performance and some gaming - it was reasonably priced, performs well enough, and more importantly, the thin bezels and lack of logos is quite schmexy - will have a hard time going back to anything branded. The LG comes w/ Freesync but I have since swapped out my Vega 64 for a 1080Ti, and as you mentioned, HDR is pretty pointless atm on PCs so ¯\_(ツ)_/¯. LG showed a slightly improved 32UK950 at CES.)

Anyway nice build writeup, didn't spot anything too out of wack on the build-side and the inclusion of the CL timing chart was a nice thing since I've often seen people get confused/mess that up.

As a fellow long-time Mac user forced to migrate (mostly in Linux, but Windows for VR and LR) I liked the part of the writeup on environment/keyboard tweaks. One thing I didn't see was about privacy. Windows 10 is very invasive. I used O&O ShutUp10[1] to go through all that stuff but there are a lot of tools [2] and other considerations [3].

Besides WSL, I've still found Cygwin to be indispensable as there's still system-level stuff that doesn't work outside the WSL (interacting w/ PowerShell scripts and such).

Not only between displays, but also between lighting conditions in the environment where the display is used. In principle, you should recalibrate every time you switch bulbs – even more important any time the monitor moves to a different room!

My understanding is that calibrating the monitor only takes the light emitted from the monitor into account, so the environment doesn't matter for calibration. That said, the way we perceive colour varies depending on environmental lighting, so if you want to be particular you should use D50 or D65 lights in the room, especially if you're printing.

It depends on the calibration device you are using - some also take ambient light measurements to compensate.

In what sense are they calibrated if things vary between displays?

They do a base calibration. Do a Google search for Dell Calibration report. It shows what they calibrate. Keep in mind, it's still a pretty loose calibration. I've never once gotten two of the same models that look the same out of the box.

This has driven me nuts more than once. I’ve very intentionally ordered two “matching” monitors at the same time, supposedly from the same lot, and they were vastly different. It may be an overreaction but since a number of years ago I’ve gone to just one big and nice monitor (even if it’s not technically as nice as the others) because those details get in my head so much.

As the saying goes: “comparison is the thief of joy” - so I remove the second thing to directly compare to.

Factory calibration is a thing in UltraSharp line, can't be compared to hardware calibration but works pretty well out-of-the-box.

I am under the impression they do some basic tests that don't entirely accommodate for uniformity of illumination and consistency of color across the display. In other words - I think maybe they only test one part of the display.

ICS profile with the screen’s unique profile baked into the EDID? Just spitballing.
