As I conclude another OLED gaming monitor review, I have little new to say. The Corsair Xeneon 34WQHD240-C delivers the same stellar image with deep contrast and saturated color as every other OLED. Its Quantum Dot layer widens the gamut over displays that lack the tech, and it has the lowest input lag I’ve measured from a 34-inch ultra-wide. In addition to that, it has sleek and unique styling and a couple of points over the competition. But realistically, buying a bad OLED gaming monitor is still impossible, especially in the 240 Hz category.

I could complain about its lack of internal speakers or LED lighting, but how much do those things impact gameplay? Not one bit. If you want a light show or tinny sound, there are other monitors out there, but you won’t get the 34WQHD240-C’s cool look. It isn’t the only white display available, but it is one of the rare examples. If nothing else, that might be a decider for some buyers.

If you have around $1,100 to spend on a gaming monitor, an OLED like the Corsair Xeneon 34WQHD240-C is a no-brainer. There is nothing about its features or performance that makes me hesitate to recommend it.

    Is there power delivery included in the USB-C video port and how many watts?

    So once again TH takes no notice of forum comments from previous monitor reviews, just be ignorant !

    Cons-
    No internal speakers or LED lighting
    Incorrect, to me and probably a large percentage of buyers, this is a Pro, stop being bias !

    Regarding the comparison of input lag, on which firmware we're the screens tested? I don't know for all screens, but input lag on the Alienware, has been reduced with firmware upgrades.

    The pixel layout on the earlier panel caused some text issues (it either bothered you or not) so it would be good to note if it's the same (it was on MSI's 240hz so I assume it is here too).

    Still not sold on going OLED longevity wise, but there are no good alternatives in the ultrawide space so I may end up there just the same.

    This honestly is one of the main things I'm looking for in a new monitor. I have an older 34" Alienware model, and I'm just waiting for one of the new QD-OLED models (Alienware or otherwise) to be the "One monitor to rule them all." My office is where my gaming setup is, but it's also where I do work. I would love to have a USB-C + PD connection for my work laptop when it's in use, and a DP 2.0/HDMI 2.1 connection for my desktop when it's time to relax.

    Part of me wonders if the 100w power supply would push the heat limits inside the chassis to the point where they would require active cooling on the monitor?

    I wish this monitor had Gsync Ultimate but not instead of Freesync Premium Pro. I would love to see more monitors that are certified for both.
