Screen resolution settings NUC 2820 and Panasonic Tc-p50x3

My display is to large for my screen my resolution is set to 1920x1080. I have made adjustments to the tv's aspect settings and have not been able to fix this however I have found that if I hold the Windows + period keys the display fits perfectly but only as long as I hold the keys. The Intel driver has no scaling or aspect settings that I can change. Is there a way to make the change made by holding the Windows + period keys permanent? Thanks

Note last reply dated 31 March 2015. Appears to be a driver problem.

Thanks Popeye for your reply. I have tried the same NUC on another panel with the same resolution and it displays properly. The drivers were installed by the Intel Driver Utility. Any settings in the driver that might correct the problem have preset values that I cannot change. However Windows re-scales the display when I use the keyboard and press the Windows key and the period key but it drops the -re-scaling as soon as either key is released or any other key is pressed. Until Intel changes its driver, or Panasonic updates its firmware I am stuck unless I can modify the registry to make the key press permanent. I need insight if this is possible.

Thanks again Popeye. I tried the registry tweak still no joy, also tried Display1_AddUnderscanPercentageHDMI and Displayx Resolution but I don't really have a clue as to what to change the entries to. I have a partial work around my TV has aspect presets that I can change on the fly. if I set the resolution to 1366x768 and select the Zoom preset I get a full picture lol! Thank you for your help, I'll also look on the Intel forums If I find a solution there I'll post it here. If not I'll try USB out to HDMI in and see how that works.
