Would using Mini Display Port to VGA be a safer option?
Again, is it a TV or a dedicated computer monitor? Does that monitor not have DVI input?
I think it may be because you have the mirroring on. That limits the max resolution to 1280x800, which TVs don't like
Yes it is a monitor that can be used as a tv and does have a DVI-D input.
I want to use my MacBook in clamshell mode what is the max resolution?
