Dell U3415W 34-Inch Ultra-Wide Curved Monitor Review

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Color Gamut And Performance

For details on our color gamut testing and volume calculations, please click here.

Once again our tale begins with the default Standard picture mode. There are only two minor issues here: magenta is just a bit off in hue, and blue is a little under-saturated at the 100-percent level. Fortunately, its luminance is tweaked up to compensate, so the resulting error is still below two Delta E — it really doesn’t get much better than this.

The gamma problems in the Custom Color mode contribute to a less-than-stellar gamut result. You can see how mid-saturation levels for red, magenta and blue are too low. We tried using the Saturation and Hue controls to fix things, but all we could do was move the magenta secondary with the Hue slider. Obviously, the Standard mode is the best choice for all-around color accuracy and performance.

Only the best professional monitors can crack one Delta E in our gamut test. Remember that we’re averaging thirty measurements, and the U3415W does it without any adjustments whatsoever — that’s pretty impressive in our book.

Gamut Volume: Adobe RGB 1998 And sRGB

Under-saturation in blue, and to a lesser extent green, contribute to a last-place finish here. We’re still mightily impressed with the U3415W’s color accuracy and wouldn’t hesitate to recommend it as a professional’s tool.

    "3440x2160" Anyone else getting tired of seeing this site report glaring errors in almost everything they publish?

  • It's 3440x1440 pixels @ 60 Hz refresh rate. It's also $899.99 on Amazon not $1199.00.

    Unless I missed it, no mention of sync of either flavor. I'm not buying a new display without one or the other. I've noticed it so much nicer in every enabled task, not just gaming.

    Judging by its size and price, Dell could have made U3415W a 4K (4096x2160) monitor.

    Thats not 4K. and no, it has no sync. This is more of a pro grade monitor, not a high FPS gamer

    IPS = :)

    Curved = :(

    21:9 = :(

    34” = :( It’s too darn short for a widescreen display. My 30” 2560x1600 already has a taller res.

    “By curving the screen just a little, the extra width fits better into the user’s peripheral vision, and reduces the amount of head-turning necessary to see the entire desktop.” Wow, just wow! This is just so wrong.

    “the image is not distorted in any way.”
    It may not be enough to notice but it totally distorts the screen and nothing you view on it will be shot in such a way. The larger TVs totally have a bowtie effect going on and it’s a total gimmick.
