I just got a flat ultrawide monitor, and despite it being an IPS panel, the edges of the screen are noticeably darker than the middle due to the angle. (If I move my head to the left or right, it's always the section of the screen most perpendicular to me that's the brightest.) This situation is shown in the top half of the image; at a viewing distance of 32", I view the edge of the screen 26 degrees off-center.

I'm trying to find out how much this would be alleviated if I had instead purchased a different monitor I was considering (while keeping the same viewing distance and monitor width), which had a 1500R curve. However, it's been far too long since I've taken a math class for me to figure out how to calculate how off-center my position would be viewing the edge of the screen at.

To phrase it like a math problem: I'm 27" north-of-center of a circle with a radius of 59". What's the angle between a line from my position to a point 15.75" along the edge of the circle from north, and a line perpendicular to that point that goes to the center of the circle?

Is anyone both knowledgeable enough and bored enough to help me?
