When i set preserve system gamma to ON the screen gets too dark for my taste.. but when i turn it off and go to gamma settings the wolf symbol/logo is not showing... so when i put it to brighter i dont see any difference ONLY when i put it to 100% bright it gets finally brighter and then its good at night and in caves but at day its a little bit too dark... what should i do and why isnt the symbol showing... my monitor is already bright enough, dont wanna my eyes to burn out...
