Uncalibrated – Maximum Backlight Level

Alienware claims 250 nits peak in the AW3423DW’s SDR mode, and I achieved close to that with a 247.9610 score. That’s enough light for any indoor environment though you’ll want to avoid the brightest spaces and sunlit windows. Black levels cannot be measured as the panel is essentially turned off, so contrast is theoretically infinite. It cannot be measured by any instruments currently in existence. The same story is true for the Aorus FO48U.

After Calibration to 200 nits

Calibration doesn’t change the contrast results. Both OLEDs have no measurable black levels and therefore, infinite dynamic range. No LCD can even come close in this test. Because the black levels cannot be measured, there is no way to determine an OLED panel’s ANSI contrast either.

    Why only 250 nits in SDR mode? Is there a way to get the ~450 nits of the full window HDR mode but restricting the monitor to 256 brightness steps? Playing game at 250 nit peak brightness is too dull even in dark environments

    Having and OLED for my home theater I was impressed with the overall ratings of this monitor for my office/game computer. I have already ordered one from Dell. I'm excited about the color accuracy and speed.

    It would have been nice if you mentioned the non-standard triangle RGB subpixel layout (green on top, red and blue on bottom)..
    Because OS's and rendering tools are not built around this layout, you will get text and window border fringing.

    This looks to be an outstanding display and I, like others, would love to have one. The price is much lower than initially expected and while that's great, it's also caused an issue with regard to availability. Checking the Dell site before posting this, the delivery is currently June 15th and that's with it being expedited (and at additional cost). That pretty much sucks for someone looking to spend money and get it soon, but I guess this is the way it goes for wanting to be on the bleeding edge... along with everyone else.

    Looks like I'll have to "suffer" on with my HP OMEN 27 for the time being. It's TN and not as pretty, but it was priced nice when I got it and does the job with full G-Sync.

    This at least springs hope that if you order now, you'll get one eventually. Or Dell doesn't want to an indefinite "sold out" button.

    Either way, they won't charge you until the order actually ships, so there's that.

    I suppose... but life has priorities and this one is at the back of the line at this point. :confused_old:

    Alienware brings OLED to the desktop with its AW3423DW 34-inch Curved Ultra-Wide gaming monitor. It features 175 Hz, G-Sync Ultimate, HDR, extended color and infinite contrast. And it takes imaging to a completely different level.
