Are there any alternatives?

Yes, there are several alternatives. The two main competitors are the LG 27GP950 and Samsung Odyssey G7, which are around the same price when they’re not on sale. They’re almost identical to the InZone M9, though they lack full-array local dimming.

　　Meanwhile, the Alienware 34 QD-OLED offers an even better HDR experience, though you’ll have to pay considerably more for it.

　　

How long will it last?

Most IPS monitors will last at least a decade and often longer. The M9 shouldn’t be any different, though be wary of panel defects.

　　

Should you buy it?

If you highly value HDR, yes. There isn’t another monitor offering what the M9 does at this price. If you don’t care about HDR, and especially if you’re strictly a PC gamer, the LG and Samsung alternatives offer a better value overall.
