Just before xmas my old trusty 30" Cinema Display decided to retire.

Since monitors are becoming so cheap, I got myself two 27" displays instead. Rotating the two monitors as one normally would, makes a very wide desktop, and a sore neck, because you have to turn your head a lot.

With the displays rotated to the vertical position, things are a lot better! Once you get used to the annoying dark separation between the displays (a question of arranging your windows differently), this setup is pretty awesome

Both displays are the same. BenQ with a 2560x1440 IPS panel. The IPS panels are absolutely stunning, once calibrated, and with this setup I get a 2880x2560 desktop. That is particularly useful when I have Nebulosity, Maxim, EQmod, PixInsight, PHD guiding, planetarium software and Safari running during a clear night.

I've been studying display technology for years, due to my job, and here are a few points I've concluded so far:

Avoid TN panels. they are slightly cheaper and faster, but they have a very narrow viewing angle. That makes them unusable for anything but gaming.

Instead go for an IPS panel. Especially when working with images, as we normally do.

Buy a cheap probe, and calibrate the display. By doing that, and understanding color management, you'll be able to work a lot more precise, when it comes to colors.

Wide Gamut displays can be wonderful, but if you upload the images you make to the internet, the gamuth is automatically changed back to sRGB. Furthermore, the colors that a wide gamut display can show, are colors you rarely use in real life, since they are extremely saturated. Said in another way: The sRGB color space is adequate for most people.

There are only a few LCD panel factories in the world. Many different brands of displays actually use the same panel. Therefore you might want to look at prices. They vary a lot, but often you pay for the name, and the quality of the plastic. The panels (pictures), once calibrated are pretty indistinguishable between different manufacturers as long as they use an IPS panel.

Do yourself a favor, and look critically at your own display. Astro photography is not a cheap hobby, and the display is a huge part of the experience. Before LED displays, the backlight faded pretty fast. My 30" ACD was down to less than half the original luminance when it died. I loved it, but I also realize that it was pretty tired.

Happy new year
