Isn't that just arc of the circle whatever curvature rating is?
E.g. on G9 it's 1000R, that is arc of the 1000mm radius circle.
No. The actual curve of the Samsung is not linear. It's more curved in the centre and less curved away from centre. Maybe Samsung averages it out to get the "R" value. When I went to an LG 800R - an even more aggressive curve - albeit with a "normal" curve, ie. the radius is linear/constant/uniform, there was no weirdness or getting used to the curve nor weirdness or getting used to switching back to a flat monitor. All that disappeared.
I usually notice these things extremely quickly.
- 7 or 8 years ago, I noticed on the first EVER day of using elastomers that there was something inherently wrong with them from the moment you stop pressing anymore (following by lifting off). This inherent issue has only been brought to light in the sim racing community a month or 2 ago (youtube video).
- 7 or 8 years ago, I could
easily tell, by the 3rd corner of my first EVER lap of Project Cars 1, that it was based on the ISI physics engine (I had no idea prior).
- I've noticed tons of times over the years completely incorrect/unnatural/strange physics behavior. Often the fanboys and (at times) even the devs themselves will try and play it down, or use illogical B.S. arguments & examples in there desperate defense. Then, sometimes, years later, you'll see game updates notes about attempting to address those very same issues...or they'll be mentioned in the new sequel.
- 10 or 11 years ago, I noticed almost right away that there was tons of blur on my monitor even though A) it was a high-end, very fast TN pixel-response time gaming model and B) ran at 144 Hz. It was only a few years ago when people started really discussing the sample-and-hold-induced motion blur of monitors (regardless of pixel response time). Prior to that - even from reviewers - all you'd hear was "super fast pixel response times of TN + 144 Hz = amazing motion clarity"...No, not even close.
...I could go on
The point I'm trying to make is I usually notice things quite easily/quickly and - unfortunately or fortunately - flaws (or things I think are flaws) often really stand out to me and the way Samsung applies curves to their monitors, at least some models, is retarded.
