I have an Ubuntu 14.04.1 desktop that I recently built and I'm having issues getting my HDMI monitor to display correctly. I also have a DVI monitor that I've been using that I haven't had any trouble with.
It's recognized and seems to be working (I can drag windows between the two displays and work on both):
and while it looks like everything is working just fine from these screenshots, I can't actually see the top menu bar on the second, HDMI monitor. Anything selected in orange (and a bit below the window too) I can't actually see.
It's definitely there, because I can click the menus (part of which show up visible to me) - the top menu bar doesn't actually show up.
Here's the output from xrandr
, if that helps any:

Is this an issue with my GPU, drivers, or my screen? Could it be the different sizes/aspect ratio that they have in comparison to each-other?
I've got a EVGA GeForce GTX 750 Ti FTW GPU with the NVIDIA proprietary Linux x86_64 334.21 drivers.
Monitors - first one is an NEC MultiSync LCD1770NX and the second (HDMI, the one I'm having issues with) is a Coby 15" - not sure the full name. As a side note, the fact that Ubuntu is recognizing it as a 20", when it's actually a 15", might be contributing to this issue.
Edit:
So, after a bit more searching around on the internets, I found a guide that pointed me to look into the NVIDIA X Server Settings.
While the guide didn't actually help me specifically, it did help me find a setting, Underscan, that I tweaked until the display was showing to top bar. However, there is still some on the bottom of the screen that isn't visible.
This makes me think that this is a resolution issue - I'm going to try and find the native res for this screen.
