A month ago, I happened to visit event here, in Sofia, where game studios revealed what is going on behind the curtains of some of best selling games.
There were some questions regarding hardware aspects, mostly concering the GPUs, Monitors and VR sets.
Frankly, all speakers shared similar insights about the Nvidia RTX, 144hz and above curved monitors and VR. Currtently all these are still marketing trends and tech-gimmick, even in game industry, which tends to develop faster.
If one has to approach the dilemma between curve monitor or flat one, he should probably consider the service he offers and also what type of devices most people will be looking at.
Do not have hands on experience with such monitors. Think they will probably reflect more or have glare, no matter if matte of nor due the curvature, so the effect of IPS will be worse than flat monitor. I would also expect colour shift and brightness drops off as you get the to edges. This can easily bring eye fatigue.
As a rule of thumb, a person is more likely to change hardware specs than monitors, and I would personally bet on something that is proved to work and then eventually change within 3-5 years timespan, rather than hop on trends. Flat monitor is probably still better choice for majority of professionals.
