Dual monitors - HDMI Monitor doesn't display top menu bar
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:
~$ xrandr

DP-1 disconnected (normal left inverted right x axis y axis)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.

Kinda stupid that I can't just comment, but whatever. It might be an overscan problem. There should be a 'just scan' option on your TV. If not, it might be an overscanning problem with Ubuntu, which can be set in xorg config settings. Does your mouse 'hit' the top of the screen? Or does it go past the top?
