Quoted from NeilMcRae:Its a faff to do that and then go back to the playing angle so sharing the values can help folks try stuff that works for others.
My recollection of this is not great but I thought there was a value on each setting? On the TNA thread fytr was having trouble with the view angle because he was tall and used these settings which helped:
Monitor settings are now at 25 brightness and 100 contrast, with the Gamma=On.
When I had a TNA I set mine to the below based on this post in the TNA thread - https://pinside.com/pinball/forum/topic/total-nuclear-annihilation-cluball-welcome/page/57#post-4438398
Contrast 90
Brightness 35
Gamma on
