Hefty discount on the HP OMEN X 27" 240Hz, don't think I've seen it this low before. Quite an old model now (2019) but it's still one of the faster screens out there today.
Being a TN panel it's certainly not the most exciting monitor, and this is probably the most you'd want to pay for it in this day and age, so is it a bargain? I would say yes, especially if this kind of thing is what you're after.
RTINGS review for reference.
Also for reference against newer monitors, here's a Hardware Unboxed review of a different monitor where the OMEN X 27 appears in the charts.
Grabbed one out of morbid curiosity to complement my AW3423DW, as a spare screen for lugging around to LANs and other scenarios where the Alienware is less than ideal.
You get to go to lans? lucky!
