You're limited a little. Be sure that you try naming the input PC and the others to see if that helps.
I just got a Samsung listed in the subject and am looking to use it as an external monitor for my PC laptop. Right now when I hook it up it looks nice but I would like the whole picture to be smaller so that I can see more. Right now it is just huge font and huge picture, which is nice but is a bit of a waste of space for me. There's got to be a way to take the current resolution I have and shrink everything up so I can fit more.
I'm not sure if this is the right forum for this, but I wasn't sure where I should post instead.
