Honestly it is. Except for gaming, all other tasks including web browsing are not pleasing. I wouldn’t say it’s horrible like some others but certainly y prefer a smaller monitor I had a corsair xeneon flex and it bothered me a lot (and im the type of guy who can tolerate almost everything, if it just works) fortunately it malfunctioned since day one and the store didn’t have more so I got a 34 inch ultra wide oled 1440p and it is pretty good now

Semi-unrelated but I've been using a Xeneon Flex for about 2 years and I've actually come to appreciate the USB hub directly in front of me. Definitely thought the desk stand would bother me but gaining a hub without the additional cable management is kinda nice.

I currently use the Xeneon Flex and this is one of the few options available at 45" and 21:9. But I'm not a fan of such a pronounced curve so I will have to stick with the Flex for a bit longer.

I used to rock the OG 45" LG alongside the 45" Xeneon Flex on my desk. Sold the LG and bought a 34" QD OLED because I thought 2 45s was too big.... now I miss having a second 45" incredibly badly. You will appreciate the extra height.

Corsair has one, but it has the downside of being made by corsair.

I feel like my UltraGear (45GR75DC-B) has the perfect curve for its size, it's a 1500R. It's actually a bit less curved than I'd like, but I also don't feel encapsulated by it like I did when I was looking at the more curved models, and it looks better on my desk too. I use it for productivity, media consumption, and gaming, and it seems like the happy medium for all 3 at the 45" size. I looked at the 800R panels, and I actually just can't believe people like it for anything other than gaming.

Exactly this for me too! Viewing stl files, docs, xls etc just didn’t have enough height to make the width worthwhile. I ended up with a Corsair Xeneon flex instead. It has its own issues but works reasonably well for my use.
