I bought this BenQ monitor as an upgrade over a 27" 1080p Asus IPS display. I use this primarily for gaming, both on PC and Xbox One, as well as streaming Netflix/Hulu and normal internet browsing. I've only been using this for 6 days at the time of writing this review, but I will point out some key points of my experience thus far.
1. The curve is amazing for gaming. Took a little getting used to, but the feeling of peripheral vision it creates in FPS games makes a huge difference.
2. There are no built-in speakers, but there is an aux port so you can easily use your own speakers or headphones.
3. This is NOT an IPS panel display. I believe it is a VA panel. The blacks are not as deep/accurate as IPS but they still hold their own against many other gaming monitors I've seen from other big name brands.
4. The monitor does not ship with a standard DP to DP cable, which you will need to get anything higher than 60hz at 1440p. It does include DP to mini DP, as well as standard HDMI and USB-C cables.
5. I've had zero issues with using HDR in Windows 10 as I saw reported in several other reviews before I made the purchase. The monitor switches between HDR and my custom, non-HDR setting seamlessly when I use any applications that don't support it.
6. The monitor does sleep and wake-up when the input devices are powered off/on.
7. It ships in a ridiculously large box.
Overall, I think this thing is a steal at the price it is being sold for. I am definitely happy with my purchase and have no problems recommending it to everyone. If you're having trouble deciding, just go ahead and pull the trigger on this one. You will not regret it!
