Guild Wars 2

Hello, when fiddling around with the in-game settings, getting the game to a decent and constant 60FPS, I accidentally changed my refresh rate to 30Hz… And now every time I boot up GW2 past the log in and Play screens my TV/monitor(Samsung SyncMasterP2770HD) doesn’t detect the input, so I have a black screen now..

I am using a GTX 560 and the DVI to this monitor and everything else works fine, but I screwed up the in-game refresh rate and can’t change it back because my monitor can’t be changed to 30Hz(as far as I can tell).
I did some display changes and such in Windows, hoping that would work but it hasn’t.
Is there a way for me to change the settings for GW2 without it being in-game, or do I just need to uninstall and then download and install GW2 again??
I’m usually pretty good at technology and computer settings and such, but I changed the refresh rate from 60Hz to 30Hz and didn’t realize it till it was too late..
Any suggestions?

Hi Yayap.3180

Please delete the local.dat file located in your C:/Users/Username/Documents/GuildWars2 folder this will reset your ingame settings to their default options.

Ahh thank you very much! I did so and It’s working fine now, I thanks you.
