Don't overclock something if you don't have any tools to fix it...

Yeah, just grab the TV, or if your monitor or motherboard has a freakish way to fix it, do it.

Its just a setting from within Windows the monitor doesn't store this stuff its just Windows putting the value in by default.

 

Move the video plug to the motherboard out (hopefully you have one of those) and it should hopefully reset the value being on a different GPU and then you can change whatever you did and set it back to normal. Alternatively try a different cable (like HDMI instead of DVI or DP). If a different adaptor and cabling don't work then at the very least a reinstall of Windows can fix it because it wont know about the settings.

Try safe mode.

Refresh rate settings is a Windows settings, you should be able to see your BIOS and boot into safe mode. 

From there, set the refresh rate to default and you can run Windows normally again.
