Color Tracking Uniformity

Building on the 5-point testing we did in the Dell U2711 review, we’ve added testing at 9 different points across the LCD. To test this, we take our best center calibration profile and then test Delta E performance at 9 different places on the display.


 

We're adding a 3D plot visualization of color uniformity. As you'd expect, the top corresponds to top, right to right, e.t.c. as you would view the monitor normally.

We can see pretty clearly that calibration profiles are pretty localized - there’s a fair amount of deviation just about everywhere else. This is expected, especially since the display luminance isn’t the same everywhere, which we’ll illustrate later. We’ve shown in our previous Dell U2711 review that even the best monitors have this nonuniform color tracking; it isn’t to say that the display is worse at the edges, just different. Even at a Delta E of 3.17 at the most extreme, we’re still relatively in range, though much more would make a visual difference.

    Nice review, and if you mention it, I remember the nice sounds the CRT made when starting, stopping and changing graphic modes.
    I'm looking forward to more articles from you

    That's what a REAL monitor does. My 22" Sony CRT will crush any LCD out there (literally) When I get on an LCD and turn it on to no sound I get pissed. When you turn a CRT on it lets you know it means business with the *BWHHH* it makes, and the click when you change resolutions is another thing missing from LCD.

    *HUGS his CRT* Nice and warm too :D

    Now that is one manly comment right there!

    Right on, also real monitors (like a pair of 21" CRTs) give you sun tan. Only your closest friends will know that you never step outside of your house during the day.

    Thanks for the encouragement guys, I've got another monitor on my desk right now I'm working on as well, and the Spyder 3 just came in ;)

    There's a bunch more coming!

    Still looking for an LCD that won't be a downgrade from 10yr old CRT technology.
    1920x1080 for a 24" display doesn't get me excited.

    For the price $339, one can acquire one or more flagship CRT units, such as the fw900 or a7217a.

    Any event horizon guesses for when flat panel displays will be able to compete with such CRTs performance for gaming?

    I have an older 22 inch version that looks the same. I love it. The only one thing that bothers me is the frame! Can't they make the screen and the frame flat. The frame with that shape collects so much dust it's unbelievable. That's not the problem - the problem is the cleaning then!

    The problem isn't it collects dust easily; it's that there's too much dust in that room.

    Run the vacuum more often.
