The difference between the 22 hd and the 22 hd touch is $550, which is almost the cost of a Ugee. If you are thinking of spending that much, honestly I’d suggest going straight to the 27 inch. The 27QHD is bigger and has better color than either of the 22 inch models and costs less than the 22 hd Touch. You’re getting way more value for your money imo. Of course if you’re going to go that far then maybe you’d might as well go all the way and spend the extra $550 for the 27QHD touch to be sure you’ve got everything you can possibly get. My personal experience makes me hesitant to conclude that the touch functionality is worth it, but I do not have any actual experience with a multi-touch Cintiq so…
Incidentally, NWoolridge brings up a point worth commenting on. Cintiq’s have actually been criticized for not being bright enough and having a low contrast ratio. In the past their contrast ratios were an abysmal 500:1, but I checked out their new specs and it seems the display’s have been greatly improved.
The contrast ratios are (bigger is better):
22HD: 1000:1
22HD Touch: 900:1
27QHD: 970:1
27QHD Touch: 970:1
Brightness values (bigger is brighter):
22HD: 230 cd/m2
22HD Touch: 210 cd/m2
27QHD: 330 cd/m2
27QHD Touch: 330 cd/m2
By comparison, the Huion GT 220 has a contrast ratio of 1000:1 and a brightness of 250 cd/m2. I have absolutely no complaint about how bright it is and am also satisfied with it’s contrast. A higher contrast ratio is always better, but the need for greater brightness… not necessarily so. You’re going to find that a monitor which is calibrated for film and print work is dimmer than you’d expect. These on-paper values for the Cintiq’s brightness should be completely adequate.
Something good to read about this stuff: http://www.eizo.com.tw/support/wp/pdf/wp_06-001A.pdf
Having said that, NWoolridge’s point is still worth considering.
