Author's Review
This is a "pure" monitor, not a TV. One result of using televisions for a PC Display for the past 5 years was to miss most, if not all, of the recent developments in 'pure' monitors. When my mainstay 2005 26" Viewsonic began to fail*, the jig was up. It did not take much to observe that a replacement TV would cost 2 to 3 times more than a Monitor. The last pure monitor acquired is a trouble-free HP 20" LCD model. After considering a couple of other brands, I decided on the HP 2511x 25". I am completely satisfied because it does exactly what I expected and wanted. You should enjoy it too.

This beautiful device, one of the Hewlett-Packard 2010 series of 5 models, arrives in its carefully designed shipping package; the lucky owner needs only a sharp blade to open the carton and a few minutes to unpack the monitor. Included are an illustrated assembly guide (in two dozen languages), the stand, a power cable - adapter assembly, a 6' DVI-D cable, a 6' VGA cable, a Compact Disk with software and documentation, Warranty Card (1 year parts & labor), and a list of worldwide HP telephone numbers.  

Extraordinary care should be applied when unpacking and assembling the Monitor to the Stand or to a Wall Mounting device. Assembly consisted of attaching the stand to the monitor. It was complicated but the instructions were adequate. It took about 10 minutes to set up and another 5 to connect to my desktop PC. 
The stand tilts thru 30 degrees, 5 degrees forward, 25 back, and the stand slides readily, side-to-side and fore and aft.  Although it is relatively light, the 2511x is bulky and a second person would be a prudent provision.
Once done, the user is only minutes away from power-up.
A User Guide (PDF) is provided on-line and on the included CD.
It is useful to print out the key pages, especially the Adjustment instructions.

Although HP provided the Software CD, Win Vista detected and installed this new hardware in seconds.

Of the features touted by HP, the more useful ones are:

On-Screen Display (OSD): Controls, including On/Off, are labeled on the lower right-hand corner of the Bezel; however, all 5 buttons are located on the lower surface of the Bezel. The buttons barely project below the bezel and are tricky to find by touch. First Icon 'Menu', opens selects or exits the OSD Menu: Quick View, Image Source, or Auto Adjust. Each choice opens a sub-menu or list that can be navigated by the "-" or " " Buttons. When the relevant subject appears, it is selected by pressing the "OK" button. (Practice, Practice, Practice...etc.) 

Response Time: At 5 milliseconds (ms), video files and movies will display without the blurring, or ghosting, as images pass across the screen. Settings for mode include: Movie, Photo, Gaming, Text, or Custom. A personal survey of the literature indicates that 2ms is desirable for games that require split-second decision making on the fly if one is to win. So, if gaming is your forte', look elsewhere.    

Screen Reflection: When turned off the mirror-like screen surface nicely reflects images of and behind the user. When in use, the anti-glare coating absorbs much of the reflections. Adjusting the TILT did lessen the distraction. This is not a touch screen but it will collect fingerprints (ie don't touch). As the software loads, screen background and images overcome the mirror effect. Text is presented black on white and is clear and easy to read.

Cold start has been about 5 seconds; upon which, the Monitor scans all ports, detects the active one.
All 3 input ports have been tested; each one connected separately and/or with all 3 connected. When signals arrive with all 3 connected, the Default Port is (user set in OSD) used.

All are 'hot swapable"; but the PC needs a restart after changing ports in order to detect which one is "active". So it is just as well to power down. Using the OSD Menu, users can select the default cable input. In this case, the Desktop PC has a video card ** with 2 DVI ports; so it makes sense to use a dedicated DVI-DVI cable.

Cable adapters are available and are necessary for HDMI if the signal originates in an older PC video card (not so for many newer PCs.)

After years of mixing Computing with Entertainment I now prefer to keep them apart; music and movies to a Tuner or TV and PC to a Monitor. Nevertheless, the 2511x is such a good display that I cannot resist porting a movie from a DVD player now and then. 
Yes, the PC Optical Drive can be ported to the 2511x via VGA but there are no built-in speakers in this monitor; which is a common design feature in many newer Monitors.  Users may port PC sound through the PC mini Audio Out connection.

Internet feeds using DVI or VGA signals are available and both are tolerable. Even after double cataract surgery, I cannot discern the differences among the three.
And Now - The piece de resistance:

Crediting a good quality camera, I have a lot of Images of a variety of subjects that the HP 2511x renders remarkably well. The colors green and violet, reputably difficult to reproduce, show vividly or subdued, as the photo moment demands. Subjects like Rainbows over a Green Valley, Snapshots of violet garments and paintings under glass render as accurately as we would expect.
We are in a forest, critter photos display birds on a tree trunk; for variety, a Grey Fox came by and posed for me. That led me to pull the SD Card and load it into my PC - I am not given to Hyperbole but am driven to judge the outcome of this test as Dramatic. Even small Icon Size shots are detailed. 
The final test was a series of shots from Die Fledermaus, as it appeared when viewed on-line feed. The moment was caught in a madcap dancing scene - It recalled the music and story; the camera was not on movie mode but this Monitor caught the spirit of the play.
