in a word, yes.
Last year I went from a 17" crt to a 23" widescreen, effectively doubling the screen size.
When I did I went from being able to see what someone's wing was doing at 600 yards to being able to see what someones wing was doing at 3k yards.
Gunnery and general ACM improved almost instantly.
FYI I only spent 200$ on that 23".
Just got a pristine used 22" 1920 x 1080 Dell monitor on Ebay. $200 including shipping. Wow! Everything you say is spot on!
Now, why did you guys let me go for so long without a proper monitor? (just kidding, thanx again for great input)
