White and Black points, Contrast

For brightness, black level, and contrast points, we use the same colorimeter setup described earlier. Specifically, an Xrite i1D2 with ColorEyes Display Pro, and take measurements. Dynamic contrast is always turned off, as this throws off our results. We also let the panels settle in for a half hour at the respective settings before taking any measurements, though with WLED the wake up time is much shorter than a CCFL.







Black level is an important metric, since it directly represents the extinction ratio of the crossed polarizers in the TN cells. Remember, when a pixel is desired to be black, the photoelectric crystal in the cell changes linearly polarized light 90 degrees out of phase, so it is blocked by the polarizer. Higher extinction ratios (and thus better crystals and materials) result in lower (better) black levels.

We recommend running monitors at around 200 nits of luminous intensity, just because this is often where some of the best color tracking sits, and it’s enough of a balance to not result in eye stress from looking around the room and having your pupil adjust. As an aside, I personally am a bit of a light-crazy person and usually crank my displays brightness to the max (I consider 400 nits normal), but forget that I ever said that. ;)

The charts show the dynamic range in brightness, and the respective black levels at each brightness. What we’re really interested in, however, is the contrast ratio. We can see pretty quickly that the G2410H doesn’t meet the advertised 1,000 ratio, but comes close at 867. Performance is pretty consistent as well at both brightness settings.

It’s interesting that the WLED backlit G2410H doesn’t blow the CCFL backlit displays out of the water at maximum brightness. More than likely, Dell has engineered a display that uses as few LEDs as possible for the sake of power savings. The tradeoff there is that maximum intensity isn’t as high. For an eco-conscious monitor, we’re willing to accept that.

    With AMD video cards you can get rid of black borders all around as follows: bring up the latest CCC, go to Desktops & Displays, RIGHT-CLICK ON THE DISPLAY ICON AT THE BOTTOM under "Please select a display" and choose Configure, then select Scaling Options and set Underscan-Overscan to 0%.

    Thank you very much! That has been bothering me since I built my HTPC in January. Wonder why AMD set it that way by default.

    Bring back common sense. Glossy screens are asinine. GJ on that at least, Dell.

    Glossy screens are asinine on a laptop you take outdoors. Monitors are usually indoors and it makes sense for them to have some glatte or moss (half gloss, half matte, as seen on LCD TVs) to it. Full gloss really depends on the lighting of where it is.

    Time was a "green screen" meant just that - a text terminal with green phosphor on the front and nothing else. Nowadays you only see them attached to obsolete mainframes.

    I have two of the G2410's (non-H) version that I got with a discount code from dell.com for only $200 each, after shipping. I guess I got really lucky because I watched the price and discounts daily hoping to get more and it never got down that low again. A $140 price hike though for an adjustable stand just isn't worth it. Get these down below $250 and it would be worth it. The screen is really nice, though I wish they'd do a 27" led monitor and/or up the res to 1900x1200 or higher. I do miss that extra 180pixels in height on this screen

    I have two of the non-H as well. I missed the $200 sale, but got them for ~$250 last fall. Definately NOT the monitor you want for professional graphics design, but great for mixed use productivity, casual streaming/movies, and gaming (esp. at $250 or less). The auto mode was a little psychotic (brightness would vary in constant room lighting), so I moved to standard mode and manual settings. 15-17W consumption.

    Nvidia Geforce video drivers have the "Create Custom Resolution" and "Use NVidia Scaling" options that allow (with digital output) creating and scaling any custom or missing standard resolution at the correct aspect ratio. The trick is that scaling is done in the videocard, while a native-resolution signal is sent to the monitor. In essence, the monitor is displaying at its native resolution and doesn't "know" it is showing a lower custom resolution.

    For example, I find it more comfortable to use a custom 1536x960 custom resolution on a 24 inch (16:10) monitor

    For my parents' setup, I have created a custom 1080x864 resolution that is comfortably bigger for their old eyes while respecting the 5:4 ratio of their 19 inch LCD.

    It's too bad ATI is not offering these options.

    I did try that; I have a G2410 (hey, I bought it because it was on sale for dirt cheap at the time) and it's useless for 4:3 games.

    The G2410 has the annoying tendancy to stretch *ANY* 4:3 resolution that I've tried up to wide. WarCraft 3 doesn't look so hot.

    I did mess about with the nVidia drivers to try to create a custom resolution that would let me run 4:3 games at actual 4:3, but didn't get anywhere.

    I think it is unacceptable that a new monitor, even if it is just an update on an existing model, to not have HDMI.I use monitors now for my laptop at home and my laptop like many others does not have DVI out but rather VGA and HDMI. I can not use VGA if I am going to watch HDCP movies or use anything that requires HDCP. Sure I could purchase an HDMI-DVI converter but why not just add that extra HDMI spot to give everybody the chance to use their connections straight out of the box without having to purchase an adapter or look for a software solution.
