LG 24mk600m, solid monitor with an inexpensive price.

U should go survey the many brands available, I was also considering BenQ, but both the DELL and BenQ was lacking 1 port. I needed 4 ports and they each had 3. Also check out the offerings from LG like the 27UL600.

Since ur doing photoshop, try searching for a monitor which has at least 99% sRGB coverage with a colour accuracy of Delta E<2. If your PC is capable, of course, a 10 bit panel and high adobeRGB coverage (>95%) would be nice, but this comes at a premium and most people do not require it.
