Hello, I am wondering when this item is going to stock up again, this monitor is the one I desire the most and am wanting to get this. Please let me know when it comes in stock again. This isn't really a review, sorry.

My Monitor no longer turns on after only 7 months ownership. Fortunately the customer service is outstanding. Will be without the monitor for 2-3 weeks, will re-post the end results.

In Amazon Cart, but Out of Stock...PLEASE Restock!

I've spent the better part of the last two weeks researching monitors (primarily for working from home as a mechanical engineer, but also for PC gaming), and this monitor is unequivocally the best option on the market right now for my needs. While attempting to purchase the monitor through Amazon yesterday, however, it suddenly disappeared from my cart and simultaneously doubled in price. PLEASE restock this monitor ASAP! I am literally refreshing my Amazon cart about once an hour now in the hopes of being able to instantly hit the"Buy Now" button. If things go well, I will most likely end up buying another one (or even two) of these for a multi-monitor setup. Thanks!!
Patrick 2020-07-18


please you guys should restock on Amazon. A lot of other sellers are using the opportunity to sale on a higher price. Customers are really waiting. Restock soon
Kyle Cummings 2020-06-29

Restock Soon please

Not a review just restock soon please! Heard so many good things about this monitor!

Simply incredible!

I got this monitor to replace my LG 32" 2k Monitor, and WOW!!!! What a difference!! Gained 3" more inches and the curved wide screen is such a treat to look at as compared to the LG where I was literally straining my neck looking up at the whole screen. Now I literally just look left to right and keep my neck level due to the widescreen. Playing Doom Eternal on 2070 GTX on this monitor in mind blowing! The 100mhz is more than enough with a good video card to really power through the toughest of games. I truly would recommend this monitor to anyone!
