I read some reviews on B & H photo about the HP Dream Color Z24X (about $530.00) April 2014 release had bad corner illumination issues and that it was corrected in the June 2014 release. This would require further investigation to determine it's validity.
If you purchase the monitor from B&H it can be returned if there are any defects. There are product exceptions, but not for monitors/TVs under 37": B&H Photo Video Return policy
I've never had an issue returning defective B&H purchases. Keep in mind as twenty_one mentioned the quality-level of Dell and HP OEM equipment is nowhere near NEC and Eizo. You may need to exchange units before you find one without the issues mentioned in reviews.
Personally I think a standard sRGB gamut 8-bit monitor would be more than suitable for your usage (Web posting) and less expensive. With a wide gamut monitor all of your non-color managed apps will display color with over-saturation. You can setup FireFox so it is fully color managed for viewing pictures on the Web, but you won't benefit much from a wide gamut display unless you start using a wide gamut printer. The choice is yours.....
