HP WD119AA#ABA HP 2710m 27-Inch Diagonal HD Ready LCD Monitor - Black

Take a look at this HP 2710m 27-Inch Diagonal HD Ready LCD Monitor - Black

Excellent color, great contrast, and great response time, but has severe Sharpness issueBy A. PingolThis monitor has very high brightness, excellent static contrast, good black levels and low bleed (once you turn down the backlight), and excellent color rendition and saturation, thanks in part to the glossy display (less transmission loss and light scattering versus a textured/matte display). Luckily, not one dead, hot, or stuck pixel on this enormous display. HP claims a 92% NTSC gamut, and it really shows - not many other consumer LCD's in this price range can claim the same. Viewing angles are surprisingly good for a TN panel, and response time is fast even with OverDrive disabled (which it is by default, and for good reason - see below). Monitor looks brilliant, incorporating a relatively thin glossy black bezel and a minimalistic matte silver stand. While the stand may look small, it is quite robust and holds the monitor steady, and also provides tilt and pivot adjustments. Has an ambient light sensor as well, but I leave it disabled. Also has high dynamic contrast, but I don't care much for that "feature."It should be noted that this monitor needs serious calibration out of the box. HP claims a 92% NTSC color gamut (which is quite large-- even larger than AdobeRGB, which is itself much larger than sRGB), but you'll need to do a bit of work to take advantage of that. Additionally, the backlight takes a while to warm up - not just in brightness, but in color, as well (it starts off with a horrendous green tinge, and slowly warms up over the next 10 minutes or so). The pixel overdrive function is off by default, and I recommend keeping it that way. It does make a difference while on, albeit slight (I could only notice its benefits within calibration tests), but the overshoot is too extreme for everyday use (e.g., closing a window in Vista/7 triggers a fade-out effect; OverDrive will overcompensate and you'll see a "negative" of that window flash for a very brief period [i.e., overshoot] towards the end of the transition). Text readability very much depends on your Sharpness setting, but it won't be perfect considering the relatively low PPI, and an even more pressing issue, a major quirk with this display:There is no option to DISABLE sharpness enhancement! With any digital input (DVI/HDMI), you will get perfect 1:1 pixel mapping. Any adjustment to "sharpness" will only degrade the image. This monitor offers a sharpness adjustment scale of 1 to 5; 1 and 2 are useless (bordering on blurry), as is 5 (artificial eye-straining sharpness). The ideal setting is between 3 and 4, where 3 is visibly too soft, and 4 being slightly too sharp (display calibration patterns, such as those on lagom.nl, will prove this). This is a significant issue that I hope HP addresses, as none of my other displays (ranging from cheap laptop displays to high end desktop displays) have this problem - when sharpness is disabled, everything should look clear and naturally sharp (assuming a DVI/HDMI connection), and the calibration tests pass with flying colors; unfortunately, the same cannot be said for this HP display. It will become a matter of personal preference whether you choose setting 3 or 4, but keep in mind neither is ... »» Read more about HP 2710m 27-Inch Diagonal HD Ready LCD Monitor - Black.
