Are there any alternatives?

No. There are currently no other PC monitors that offer fast, 4K gaming performance paired with FALD and this level of color performance. Your other best bet is an OLED TV like LG’s 48-inch C1 model, but that comes with its own set of compromises, provided you have the desk space for it at all.

　　

How long will it last?

From a functional perspective, I see no reason why the ROG Swift PG32UQX couldn’t last a minimum of five years. But between the lack of HDMI 2.1 and rapidly developing alternative display technologies, you’ll likely itch to replace it long before it breaks, especially if you’re someone that likes to live at the forefront of technology.

　　

Should I buy it?

For most gamers, no. It has a few flaws that are guaranteed to be dealbreakers for large groups of buyers, especially at this price.

　　If you have deep pockets, and just want the best HDR gaming monitor you can currently buy right now, then the ROG Swift PG32UQX is as good as it gets But for most of us it’s like an exotic sports car: I’d like to rent it, just to experience it, but I wouldn’t want to own it.
