Color Accuracy

Something far more important than contrast ratio or brightness is the accuracy of the colors that are produced. A bright display with a high contrast ratio could still have terrible color reproduction, and it's not always possible to correct this. Most people will simply "eyeball" the display output to try and determine what looks best, and there are various color charts available online that can help. Outside of image professionals, that is often sufficient, and most users will find that their eyes adapt to whatever display they use and it is only when doing side-by-side comparisons that differences become apparent.

Monaco Optix XR Pro was used to generate reports of color accuracy. 24 color patches are sent to the display with the colorimeter measuring the resulting values. The difference between what is requested and what the LCD actually shows is known as Delta E, with lower values being better. Any score less than one is basically "perfect" - the naked eye is not going to be able to tell the difference - and scores less than 2.0 are very good. Ideally, you would want all of the tested colors to have a Delta E of less than 1.0, but few people are likely to have problems with anything scoring below 2.0. From 2.0 to 4.0, most people will be able to detect a slight inaccuracy in the color palette when comparing displays side by side, but it's not too irritating. Anything above 4.0 begins to represent a more significant deviance, and numerous scores above 4.0 will almost certainly be noticeable by just about anyone using the display.

The Gateway FPD2485W includes EZTune software to help users calibrate their displays, although this will at best provide moderately accurate results. We started out with the EZTune software, checked the results, and then proceeded to use the Monaco Optix software to calibrate the display. Unless you have a colorimeter and the necessary software, you can expect your results to be closer to the EZTune values, but outside of image/video editing that is often sufficient.


Monaco Optix XR Pro

Both displays perform very well when calibrated by Monaco Optix, but not surprisingly the out of box experience from the Gateway isn't nearly as accurate. Uncalibrated results for the 2405FPW were not recorded because it is only intended as a baseline measurement and is not being reviewed. The Dell 2405FPW is about two years old now, but it still performs about the same as the newer 2407WFP and the Gateway FPD2485W when it comes to reproducing accurate colors. We will be taking a closer look at the 2407WFP in the near future, but outside of the most demanding users any of these three displays will work very well. That's not too surprising, considering all three of them are based off of PVA panels.

The second aspect of color accuracy that we need to address is the color depth. The FPD2485W can produce a resulting color pretty close to the requested value, but how does it do in terms of gradient scales? This was something we neglected initially, and after further investigation there is definitely a lot of banding when viewing gradient scales, to the point that we would almost question whether or not this is a true 8-bit panel or if it's really a 6-bit panel. Attempts to capture the results of the banding with a camera have been unsuccessful so far, but needless to say the Dell 2405FPW shows less banding while the 2407WFP doesn't show any noticeable banding. In normal use, the banding usually isn't a serious problem, but graphics editors are likely to notice the effect. Any gradients created in Photoshop or other similar programs have definite problems in regards to producing a smooth color scale on the FPD2485W, and for some people that is a big enough concern that they will want to look elsewhere.

Note: Our review sample is from the first run of these LCDs and was manufactured in November 2006. Later models have apparently improved on some aspects of the display, but unfortunately we can't say whether the color gradients have gotten any better. Again, if colors are important to you, try to check out a display in person and bring up some gradient images to see whether or not you notice any issues.

Update: Additional information on viewing angles and color calibration for print work with these displays is available in our Acer AL2216W review.

    I purchased this monitor 11/2007. In 2/2008, the monitor completely died. I called Gateway and they refused to send me a new monitor. they would only send a refurb. (customer service reps were nasty, arrogant, and rude, when you do not agree with them they hang up on you).

    The second monitor did not work right out of the box, none of the touch control buttons lit up and they did not work, I had no way to turn the monitor on or off.

    They sent a third refurb unit, and again, right out of the box, the backlight kept turning off, I would have to cycle the power several times to get it to come back on and then it would only stay on for a few seconds. Tech support said they would take back the monitor and the speaker bar add-on (since the speaker only worked on this one monitor) and refund my money for both. He transferred me to customer service to process the refund and returns and they changed there mind and said they will not give a refund. When I asked how long this was going to go on, there reply was "until I get a unit the works"

    In all fairness, this is a nice monitor, but three bad ones in a row, and there lack of proper customer service, is enough to make anyone think twice!

    Thanks, Jarred, for the informed review. A selfish request--could you review the current Dell, Apple, and Samsung 23/24" LCDs? A friend is in the market in the next couple months and I am buying before the end of the year. From what little looking I've done, these seem to be the best candidates so far for hobbyist photo work (and movie viewing, game playing, web browsing...).

    I purchased this monitor over the weekend at a local Best Buy. Here are my results from calibrating with the Pantone/greatagmacbeth Eye-One Display 2 colorimeter using the Eye-One Match 3.6.1 software.

    First I calibrated according to their instructions, which include driving the contrast to 100%. I had to go into user color and lower each color channel to 59 (default was 100) to get the brightness down. The brightness meter stated that it was at the target 120 cd/m^2, though the results show differently. Here are the results for the calibration:

    And here is the validation results as an image of an Excel page. The Eye-One software does not give an easy way to directly export a graph, so colors tested are labeled by both RGB and Lab color values. Dunno how these compare to the values the Monaco Optix package uses, but by it's tests the results were quite good.

    As the fist image shows though, the colorimeter was doing a lot of adjustment at the dark end of the spectrum, and video suffered from crushed blacks. So I tried changing brightness and contrast until video looked good, then recalibrating. Settings used here were brightness of 76 (with individual color channels still set to 59) and contrast of 60.

    Much less work is being done to dark colors now, video looks good, and the dE is even lower now:

    Brightness is still a little higher than recommended, but not much above what turned out following their procedure exactly.

    I have this display and love it, but something I like to know about all my displays is how to access the service menu. Usually there are extra options that allow even more fine tuning with color etc...

    Do you have any connections that would be able to tell you the way to enter a service menu on this display?

    Gateway "tech support" has no idea what I am asking and just send me spec sheets or links to what the OSD looks like.
  • JarredWalton - Wednesday, February 28, 2007 - link

    Not sure what more could be done to fine tune the display. If you go to the user settings you can adjust RGB colors, but being an LCD it doesn't really make a difference whether you do that on the LCD or in the Windows drivers. They both end up accomplishing the same thing. I have never looked into "hidden service menus" on any of the LCDs I've used, I'm sorry to say.

    Jared:

    Thank you for the review. I'm very pleased that you will be reviewing monitors again. In your future LCD display reviews, I suggest that you identify the manufacturer and model of LCD panel in the monitor, and continue to identify the manufacturer and model of the signal processing chipset (you did in this review), as in Kristopher's November, 2003 "Dell UltraSharp 2001FP Preview: Gaming LCDs for the Masses" review. Finding information about an LCD monitor's panel and chipset is difficult at best. I suspect that many enthusiasts would often consider the panel type, brand and model when choosing monitors, if that information was readily available. In fact, I frequently read discussions about the merits of S-IPS panels over S-PVA panels. Additionally, would you also alert readers when a monitor manufacturer uses different types of panels in the same monitor, i.e., model. This practice is disconcerting; Consumers simply can't be certain that the specific model that they purchase will have a specific panel. I believe that a vocal outcry would eliminate or substantially reduce this practice.

    Currently, the FPD2485W is listed for $680 on the Gateway web site, while the regular price of the Dell 2407WFP is $750. Dell routinely runs sales, however, and the 2407WFP is available for $675 right now. You basically end up with two very similar monitors that cost about the same amount, although the <U><B>Dell comes with a three-year warranty included making it a slightly better deal.</u></B>


    Gateway offers a $29 extended three (3) year warranty for the FPD2485W making it the same as the Dell 2407WFP for $40 less.
  • JarredWalton - Monday, February 26, 2007 - link

    The Dell is currently (or was last week) $675 with the three year warranty. The Gateway is $680 + $30 for a 3-year warranty. So right now, the Dell is clearly less expensive. If the price of the Dell goes back up (which is almost certainly will at some point), things change a bit.

    The problem is, darker blacks are good but brighter whites are only good up to a certain point. Anything above 400 cd/m 2 is far too bright in our opinion. As you can see, the black levels of both the Gateway and Dell LCD are equal, /
    quote:



    Dell achieves 200cd/m2 while gateway achieves 400, 405.21cd/m2 to be exact.

    Aren't you supposed to compliment gateway for its excellent white brigthness while bash dell's inferior test result? or are you saying gateway's performance is nothing to sneeze at because it went over mere 5.21cd/m2 of your recommendation of 400cd/m2

    I hate to speculate, but I'm very disappointed in this review.. reminds me of biased reviews from Toms.
