im in the process of buying a new monitor for image editing too.
i take my time, i search for 2 month now.
i started with a budget of 500-600 euro.
bought the DELL 2713H and HM (actually 2 of them each).
i send them back after 2 days. both had ugly lightbleeding and inhomogen colors.
then i ordered another two -> same results.
they were actually worse then the dell 2711 i have, when it comes to homogenity and light bleeding.
the left lower edge showed a grey not a black (it´s a common issue with dell when you look at customer reviews).
overall i found the new DELL monitors dissapointing. good allround or game monitor.. but imho not really good for image editing.
you can do image editing with them, sure. but they all have their flaws and they show a great deal of variance. i read monitor reviews about the dells and was suprised that the ones i had were so bad. reading CUSTOMER reviews i saw im not alone with my opinion. i guess im lucky that my 2711 is relatively good (thought he now shows dead pixels).
then i bought an Asus 27 inch and two LG´s and a few others, i spare you the details.
after much searching i decided that i had to increase my budget.
there are no really good monitors for image editing around 500 euro in my opinion.
the next monitors i will test are the eizo CX240 (950 euro) and CX270 (1300 euro).
i know that is much more then you (or i) wanted to spend.
but the monitor is a very important, you look at your monitor all the time judging you images.
imho it makes no sense to skimp on a monitor.
especially the greys and color gradients make a big difference.
some monitors show banding in gradients. they are not in the images, it´s just the display.
a monitor that shows banding is a no go for me. i had one before and it was annoying.
you will notice that especially in computer generated images (i do 3D too) and when you shot people on a grey or blue background.
i use 16 bit for all my tiff files and i still got banding.
when editing images with fine gradients i always had an eye on creating banding because it was so easy to introduce banding.
then i edited one of my images on a friends 10 bit quato monitor and noticed that there was no banding.
that was when i noticed it´s not the 16 BIT images that showed the banding. it was my monitor who could not show these subtle details in color variation.
eizo has 5 years warranty. if the monitors are what i expect then i pay the 1300 euro.
i spend so much on camera gear... a good monitor is as important.
if not more important then a slightly better sensor.
That monitor looks like a good one for the price. No need to spend several thousand dollars for a professional model.
you don´t need a 1D X or 5D MK3... the differences you see compared to a 700D or 70D in prints are marginal.
you don´t need a 2000 euro monitor, i agree.
but cheap monitors around and below 400 euro are not made with image editing in mind.
