Overclocking a dell u2414h help please

[zT.]

Alright, thanks for the help ToastyX!

One more thing, since i overclocked it to 75Hz when i use a plataform like Netflix, also with Silverlight, i get erros like 6031 & 6035. Looking at Microsoft website it says:

6031
The integrity of the secured video output connection has been compromised or lost.
6035
A new graphics connection was added during playback and playback was halted.

Do you know something about this? The video stops at random times and i have to refresh the page so i can watch the channels again. I've looked at some posts on the internet and some guys fixed it by disabling the second monitor but in my case i only have this one runing.
