Hi,

When I tried to change the settings in "Screen Resolution", I always get 
this error:
http://i.imgur.com/idb6Cf4.png

It seems that the Intel HD Graphics 4600 display driver may be unstable.

Although I can access the settings as shown below, I can't change them. 
And I don't know how to change them as well.

If I try to change any of the settings, I will get an error similar to 
this below.

Any advise?
