Hello, /v/ here
I have no fucking idea how to use the formula to calculate quake fov for 3440x1440 21:9

atan(tan(120*pi/360)*0.75*resolution_x/resolution_y)*360/pi

Just give me the exact value for 90 and 100 fov you nerds.
Thanks.

hint: that """formula""" simplifies to $120\times0.75\times\text{x resolution}/\text{y resolution}$ . I don't know if it's right or wrong, whoever prepared that .png is a certified retard. You know your monitor's resolution and know how to use a calculator, right?

And your """"""""""""formula"""""""""""" simplifies to $90 \cdot \frac{x\text{-resolution}}{y\text{-resolution}}$ . Sad!

You need to use the atan2 function to remove sign ambiguity

either we're supposed to be trolled or op just discovered that he's been trolled

finding an actual equivalent-FOV formula given a standard FOV being set at 4:3 resolution is left as an exercise for the reader.

What the fuck is the atan2 function, sig ambiguity? you know what, I don't fucking care. Just give me the fucking numbers. Hurry!!!

Neat.

Just move the viewer closer, and you have the answer for all other degree-angles. Probably should've gone in the sqt thread. The first step was recognizing that the given formula was fake.

In case OP is too dense to use this.

Are you fucking kidding me, this looks hideous. This doesn't look 90 fov to me. y'r'll fucking retarded.

>formula form
2*atan( .75 * R * tan(A°/2) )

Where R is the aspect ratio and A° is the 4:3-equivalent viewing angle in degrees. OP's image just put in 120° as A° and made it out like that was the general formula.

Yep, this one looks good enough. Took longer than I thought. After all your stupid board catalog is filled with wojak and pepe shit too, didn't expect much for you nerds.
Bye forever!
