They are the best monitors I have ever used.
sorry but that doesn´t say much.
dells are fine consumer monitors but not first choice for a color managed workflow.
personally i don´t understand how people can spend thousands and thousands for camera gear but then skimp on the one device that shows all the images.
the 2713HM is relatively nice and cheap monitor.
he has some issues, bleeding in the corners (amazon germany is full with complains), average uniformity.
i have one for office work.
he has some bleeding on the lower left edge and 1 subpixel error (always red pixel).
i exhanged the monitor 4 times.
2 had pixel errors and two really worse bleeding and uniformity issues.
because i only use him for office work on one of my system i decided to stick with the last one. uniformity is ok for bare eyes. the bleeding is not that bad and the subpixel doesn´t bother me. i don´t notice it, have too look closely to find it.
thought the dell monitor is no competition to the nec or eizo monitors i have.
but it´s only 1/4 respectively 1/8 of the price too....
ps: i just bought the new eizo CX271 for a photographer friend (i do his IT stuff) and it´s a really nice monitor. i would say image quality is as good as my CG series eizo.
that´s a monitor i would recommend to any enthusiast photographer.
