Display resolution messed up

[GhostMcFright]

I have a 1980*1070 full HD TV (1080p) and using Nvidia 980 GTX. It was going well but suddenly I'm seeing multiple unsupported resolution beyond 1980*1070 and now if I want the display screen to show in full, I have to set up to 1980*1200 instead of my TV's maximum resolution as mentioned earlier. Even Nvdia fails to recognize and showing native resolution for 1024*768 for some odd reason. Not sure if that's default native resolution or something else.

Any solution? :/
Googled countless times for this but to no avail.

GPU
Also I have a 1080p monitor which should have shown 1970x1080 as native but Nvidia panel shows 1024x768 as native.
