One critical thing to look at is whether it's a TN or IPS display. TN displays have a color and contrast that is highly dependant on the angle of view, i.e. you can spend 1h fine-tuning your image, move your head a little, and discover how bad the image is from that other angle. You absolutely do not want this. I use a Dell u2713HM: - 27 inches => I do appreciate the 3 extra inches compared to 24'' which is more or less the standard these days. - WQHD display (2560 x 1440) => again, very appreciable compared to 1920 x 1080 or even 1920 x 1200, both for photo and non-photo applications. - 99% sRGB support, with good color renditions even without calibration. That's good enough for me. I guess a more advanced user would want a wide-gamut screen. > * What graphics card do you use, and do you use it with a FOSS > graphics driver?

A few numbers with my GPU: http://thread.gmane.org/gmane.comp.graphics.darktable.user/6320/focus=6510 Some instructions here: https://www.darktable.org/usermanual/ch09s02s03.html.php dt requires at least 1 GB RAM, I would advise at least 2 GB in case the requirement increases in the future. I used the "floating-point performance" indicator from http://gpuboss.com/, which seems a good heuristics but I didn't actually benchmark dt to see how other numbers impacted it. It seems Radeon cards have better floating-point performance than Nvidia at equivalent prices. > * What colorimeter/photometer do you use? And how does it play with > Linux? I tried the Color Hug: http://www.hughski.com/ I loved the idea, and the price. Tried it on 4 or 5 different displays, each of them resulted in unusably red colors (I mean, unusable even for word processing, not just a little red). Many people were having the same issue on the user's mailing-list, but the developper was busy working on a new generation of device and nobody really found a solution. It seems you can get better results if you use it in combination with a spectrophotometer. I had to get a refund for mine (but you may get luckier than me). I now use an X-rite Color Munki Display. Really slow, but I don't calibrate that often so it doesn't bother me. Well supported by Argyll (I use dispcalGUI). -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ------------------------------------------------------------------------------ _______________________________________________ Darktable-users mailing list Darktable-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/darktable-users
