Philips 276E6 27-inch Quantum Dot 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.

Grayscale Tracking And Gamma Response

Our grayscale and gamma tests are described in detail here.

The Color Temp mode is nearly perfect out of the box on its 6500K preset. The only rub is you can't adjust Brightness without switching the 276E6 into its Adobe RGB mode, which does require adjustment. As long as you're OK with the bright 370cd/m2 output, Color Temp is the way to go.

Here's what we mean when we say "too green." Without some adjustment, the Adobe RGB mode looks pale and flat with an obvious tint to brightness levels above 10 percent. Even with the expanded color gamut in play, images don't look their best here.

Calibrating the Adobe RGB mode produces the best possible performance. The 276E6 matches any professional screen in the quality of its grayscale tracking. You can thank its precise RGB sliders with 100-step resolution for this excellent chart.

Here is our comparison group.

You can see that the Color Temp mode has no real flaw and is perfectly usable. This is a great out-of-box result. Our only complaint is the locked-out Brightness control.

Though calibration is required in the Adobe RGB mode, it only yields a small improvement over Color Temp. But that is the price for having control over brightness, which is fairly important in our opinion.

Gamma Response

In the default states of both the Color Temp and Adobe RGB modes, gamma tracking is quite good with only tiny dips at the 10 and 90 percent levels. You'll see later how this has a positive effect on color balance.

Calibration leaves gamma tracking largely unchanged. The average value has dropped slightly but we can't see a difference in real-world content. If your tastes run to a darker or lighter presentation, there are five total presets ranging from 1.6 to 2.8.

Here is our comparison group again.

.15 is a fairly tight range of values and lands the 276E6 mid-pack among these high-end displays. We're glad to see that Philips has adhered to accepted standards here as they showcase their new technology.

We calculate gamma deviation by simply expressing the difference from 2.2 as a percentage.

With a 2.15 average value, gamma runs a tad light but again, it's not something you'll be able to discern in normal use.

    Finally! I've been really wanting to see this technology come through to more than two products (that I'm aware of)

    I'm not too concerned with power consumption at my desk. How about phones and laptops - will we see quantum dot screens there soon?
  • 8 bit, 1080p, next!

    Takes some design ability to make a 27" look more like a 22", good job on those monster size white bezels. :p
  • melgross_85
    $299 is pretty cheap. I'd like to see what they could do with a higher budget.

    Love the tech, but the screen specs at that size will make it look like monster dot technology. 1920 x 1080 at 27" looks just horrendous after using a higher rez monitor. Some monitor OEMs are a bit behind the times it seems (although this tech is pretty cool).

    For gamers seeking vivid color and a bright image, your monitor has arrived. 18ms is an excellent score for any 60Hz display

    I can only LOL and I never LOL. 18ms response (57ms total lag) is just god awful terrible. These arbitrary endorsements are getting lame.

    "18ms is an excellent score for any 60Hz display"
    is that a typo ?
  • CaedenV
    Did I miss where it has a price? It can be the best consumer display in the world, but if it is $5,000 then that would not make it a recommended buy.
  • Nintendork
    All this quantum bull* and still 1000:1? Meanwhile tablets and smartphones using IPS neo from jdi with near 2000:1.

    Or even better an RGB OLED display.
