Difference between MDH and MDV?

[x0tek]

So, assuming one's FOV is similar between games, then using MDH will be exactly the same as CM/360.

However, using MDV will still differ quite widely between games. Could someone explain this to me? I'm really curious as to the technical reasons behind this ^^

I looked up the original technical thread discussing this, and it doesn't make sense to me at 0% values

Keep in mind there's nothing fundamentally different between them they will both give you the same values if you use the same converted mm% e.g.

100% vertical mm -> horizontal mm (16:9 monitor) 100%*(9/16) = 56.25% So 100% vertical monitor distance match will give you the same sensitivity values as 56.25% horizontal monitor distance match on a 16:9 monitor

30% horizontal mm -> vertical mm (4:3 monitor) 30%*(4/3) = 56.25% So 30% horizontal monitor distance match will give you the same sensitivity values as 40% vertical monitor distance match on a 4:3 monitor

 

According to this math, 0% MDV and 0% MDH should be identical...but they aren't  

Specific example - 

"CM/360 &  MDH 0%"

"MDV 0%"

Is this just due to the slight VFOV discrepancy? 

Thanks so much!

They are only the same as long as the aspect ratio is the same. It seems like you have a different aspect ratio on CSGO, which makes the calculation different

It seems like you have a custom 1810x1080 resolution on CSGO, which is different from 1920x1080.
