Dell S2417DG 24-inch 165Hz G-Sync Gaming Monitor Review

Grayscale, Gamma & Color

Grayscale Tracking

Our grayscale and gamma tests are described in detail here.

There aren’t too many choices to confuse matters here, so we’re showing you before and after charts. The first result represents the S2417DG’s Standard picture mode as delivered from the factory. There isn’t much need for calibration based on these measurements. Errors are all below the visible threshold.

We made a few small adjustments to the RGB sliders but most of our gains in the brighter steps came from reducing the Contrast slider from 75 to 68. That tells us the monitor’s default setting clips some high-end detail and also clips green and blue, as seen in the pre-calibration chart. As you’ll see below, gamma is the real issue that needs to be addressed.

Comparisons

The S2417DG takes the top prize for out-of-box accuracy and narrowly misses the top spot after calibration. We’re glad to see this kind of attention to detail in a gaming monitor. This is a standard that should be met by every computer display, regardless of its price or intended use.

Gamma Response

Gamma is the only area where we had some concerns. The default trace rides close to 2.2 until things go south at the 60% mark. It’s solely due to a contrast control that’s set too high. If you do nothing else, please change that slider from 75 to 68 on your S2417DG. It will firm up grayscale accuracy in the brighter steps, and detail that was previously washed out will become visible. Even after calibration, this monitor’s gamma could be better. It’s a tad dark considering the contrast level. An additional preset in the OSD would be helpful here.

Comparisons

Post-calibration gamma tracking is fairly linear, which enables the S2417DG to finish third in our comparison. The overall value of 2.32 drops it down to fifth, however. It’s a small difference, but if the panel tracked at 2.2, the image would have a bit more pop, especially in the mid-brightness (30-60%) areas.

Color Gamut & Luminance

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

The S2417DG’s native color gamut shows a little under-saturation in red and a little over-saturation in blue. These are minor errors and they’re mostly compensated for by engineered tweaks to the color luminance levels.

Our calibration has almost zero effect on the saturation measurements, but the change in gamma has brought better balance to the luminance chart. We were not able to fix the hue error in magenta, but that is also very minor and does not detract from real-world image quality.

Comparisons

Calibration takes the average Delta E 2000 error from 3.65 to 3.23 which is an imperceptible change. We still feel that fixing the gamma is the most important takeaway from our adjustments. And you can realize the same gain by simply adjusting contrast as we did. While 3.23dE is acceptable for a gaming monitor, the other screens here perform a little better. There are other considerations in favor of the S2417DG, however. Read on.

    It's a shame this monitor is so much more expensive in Canada, $739 CAD which is about $545 USD. That's not even including taxes :(

    For the love of God, add contrast information to the chart in the first page. It's the single most important piece of data after the resolution.

    Does this kind of screen support Nvidia 3D Vision? The refreshrate is more than enough since 120hz sufffices......

    For you. Some people want more. Thats why BenQ is releasing 240hz monitors.

    I never thought I would say this, but DO NOT buy Dell monitors especially of the current vintage. Dell's quality control has gone to hell. I had to buy 6 of the S2716DG the 27" version of this thing and return 5 of them just to get one without a bad pixel, or some other defect. If it weren't for Best Buy return policy I would have been SOL.
  • s4fun
    The bad ones have defects and failure modes of the follow:
    1. Bad pixels - usually pixel stays black or fails to get past dark gray
    2. Buzzing Coil whine, some much louder than others
    3. Backlight white is not always the same "white" and it differs from monitor to monitor, and changing the brightness setting does NOT equalize them. Some "white" looks more yellow than others, the variation is too wide for something that should be consistently manufactured.
    4. Deep sleep failure mode 1: refuse to wake up
    6. Deep sleep failure mode 2: refuse to go into deep sleep mode even with the setting enabled and sits and vampires 12 watts of power while supposedly in "off" state, screen is black.
    5. Bezel plastic has rough cut unpolished edges but not always at the same spots.

    What a piece of trash.

    Until OLED reigns supreme, we must only allow AMVA+ panels with 60-120-240Hz. TN looks like c*rap and IPS with the annoying IPS glow too.

    You don't really want MFR contrast info... only because, like TVs, it's MFR subjective. If TH or other testers have a specific test that uses the same criteria across all brands and models, then fine... it will actually be a comparable attribute. (Someone PLEASE correct me if I am wrong here.)
  • -> TN panel, nearly 2017. As if there aren't a dozen or more G-Sync TN monitors already in all refresh rates and resolutions.

    What a waste.

    If they add Response time and Brightness, which manufacturers also lie about, I do not see why not add contrast too. We then have the actual review to see the real number, but at least, if the chart on first page says contrast 1000:1, we know that the actual contrast will be between 800:1 and 1100:1, and not 4000:1.

    Lemonsquare,
    TN is not "a waste" of the features and price put it in its own niche. IPS with the same feature set would be more expensive.

    After you hit 1080p at 80-120dpi, contrast is the most important. I argue 4k at 40 inch + is the next time that resolution is even a factor in a display. Personally use a 1200p monitor, wish more 16:10 monitors existed.

    military did research, we are able to on average accurately identify things shown at 300fps, and the upper limit is thought to be around 500 for what we would call perceivable.
  • therealduckofdeath
    This is why I jumped off the Team Green coach and joined the Red Team. Yes, Nvidia has better performing hardware, but, I am not going to pay 400 bucks for a TN-based 24" display just because Nvidia wants their cut with the $100 Gsync tax.

    The 240hz models are only available in 1080p. tthe 1440p version of the BenQ are 144hz. This monitor pushes more pixels than even the 240hz BenQ. You'd have to have a 1080p monitor at nearly 300hz to match the bandwidth Dell pulled off here.

    This Dell is a pretty sexy monitor for the price.

    I'm extremely confused by this review. Are we sure this was for the Dell S2417DG? The review states that it has tiny speakers, I don't think it does. It also claims a good level of out-of-the-box color accuracy but elsewhere it's noted that the color gamut and accuracy is weak. What gives?
  • Hazeion
    I want to clarify. There are no speakers on this product. I have the product myself. I don't know where that came from. Maybe they were reviewing the 27" monitor?
  • bobpage
    The S2417DG I received from Dell (US) this week has a gamma of ~1.3 across the board, requiring a gamma correction curve of ~0.65 to get somewhere near 2.2 gamma. The colors then look approximately right, probably more saturated than the IPS panels I'm used to.

    how do i get the speakers to work they are not working with hdmi or display port

    What calibration did he end up using it made no sense
