I received a perfect monitor. Minimal bleed, no dead/bright/stuck pixels, and the 100hz mode worked perfectly. If you can afford it, and aren't an uber competitive FPS gamer who might prefer a 144hz or even the 200+hz super quick 24 or 27 inch monitors , this is the best monitor out there.

After months of waiting, I was finally able to get my hands on an Acer Predator X34 monitor. This is the first ultra-wide display with g-sync, running 100hz on a curved, 34" 3440x1440 screen. If you're not an e-sports athlete or hardcore fps gamer, then the miniscule differences between 100hz g-sync and 144hz (or even 200hz) will go unnoticed. With software like FlawlessWidescreen an HxD, almost EVERY game in my library can take full advantage of the 21:9 aspect ratio. It's simply amazing.

Amazing! Overclockable to 100Hz. Supported natively in Windows 10. The color accuracy and sharpness is absolutely stunning.

Notes: Use a displayport cable to overclock and get the full benefits. OC is disabled when using HDMI and due to HDMI limitations, you will only get 50Hz maximum using HDMI

You can use a mini-displayport to displayport cable to connect your mac to this display. That's what I did and I am able to get native 3440x1440 resolution in Mac OSX (El Capitan). You are still limited to 60Hz because that's the max that Macbook Pro (retina) can output.

The on screen display on the monitor is total garbage! It WILL take you a while to get used to the menus. The good news is that once you set it, you can forget it so the OSD menus are not a deal breaker. One suggestion (strongly advised): increase the OSD timeout menu to something like 15 seconds so that you can fumble around for the right buttons.

No dead pixels or bleeding issues. There is IPS glow but that is expected and only viewable on dark backgrounds.

Absolutely Gorgeous display! Ran Unigine benchmarks and the g-sync really got its chance to flex its muscles. Also a great monitor for video editing, I could see myself wall mounting one of these and using it as a secondary monitor so i can have my video timeline all spread out. just nice to have a lot of pixels to work with.

I love this monitor! Though it can be a pain to go in and set everything up to run at the new 21:9 aspect, but it's totally worth that little bit of hassle! The 100hz refresh rate makes a noticeable difference compared to 60hz when playing games. Can't say for 144hz monitors as I have yet to see one up close. I believe that Acer has everything fleshed out with all the problems that plague this monitor, as I have no issues with it at all so far. There is a fair amount of BLB, and IPS glow in the corners. Since I never really noticed it before I don't take issue with it, you can only really see it when everything is black. I don't think I need to tweak it anymore than lowering the brightness. Great monitor, but I still don't think its quite worth the $1300 price tag, that's it's only con to me.
