    Great value for money, but ...

    Great value for money, but forget HDR! I even get the impression that the image loses a bit of quality when it is enabled (w10)...
    Moreover, it suffers from very pronounced IPS glow ... You notice it little in use in a well-lit room, but in the evening when gaming, if there are dark areas the glow is quite visible ... Well, given the price and the tech (IPS), I suppose that should be expected, but the size of the glow surprised me a lot.
    It has a coil whine problem at the power supply level (around the adjustment buttons). The only way is to set it to 260hz (OC). Since the coil whine volume (high-pitched whine) increased with frequency, it took me a while to figure that out... My only point of reference being an old 60 hz (TN) monitor, this monitor was a game changer for me. The smoothness (thanks G-Sync!) is stunning! Apart from a few flaws, I think it's worth it given its low price!

    Good 1440p monitor

    This monitor is pretty good for its price, it lets you play at 1440p 260hz, you'll never go back to 1080p

    As described and perfect

    I've been using this monitor for some time now and I'm really satisfied with it. The colors are pleasant, the image is sharp, and the contrast is more than sufficient for everyday use. The smoothness is a real pleasure, both on the desktop and in games. For the price, I think it's hard to find a competitor. I absolutely do not regret my purchase and I recommend it without hesitation.

    DO NOT BUY! FACTORY DEFECT ON THIS MODEL

    I strongly recommend against this model.

    On my unit, used at 2560 × 1440 at 240 Hz via DisplayPort, the image cuts out completely for about 2 seconds every 5 to 10 minutes, before coming back as if nothing had happened. All connections are properly made.
    For a monitor sold primarily for high-frequency gaming, this problem is a deal-breaker.

    Before buying it, I had already seen several user reports (on forums) about this same Q27G4ZR describing exactly this problem: black screens lasting 1 to 2 seconds, but I had told myself those people had simply been unlucky and that it only concerned a few units.

    Aside from this flaw, which is NOT negligible, the monitor seemed good to me: a nice image, excellent smoothness, and very attractive features for the price, but for gaming, look elsewhere.

    So I’d rather return it and go for another model.

    I am convinced

    I am convinced by the screen but the reason why I gave 4 stars is that this screen has a cable that bugs a little, it’s not very bothersome but just to warn you that sometimes when the screen suddenly turns off it means that the power cable has barely come loose
