Samsung LED "PC Mode" colors are not good

[lenix]

Hello,
So I purchased a UA40D5000 recently and I've connected it to my main desktop using HDMI cable ( connected to hdmi1 ).
I edited the Hdmi1 label to PC to get pc mode, now the text looks smoother but the colors are not vibrant like normal mode. When I try to watch movies/shows they look much better in normal mode.
How can I fix it in PC mode? Or should I just ignore pc mode and keep running normally?

I tried to change some settings in the nVidia control panel but I couldn't get the image to look as good as normal mode.

If you can shed some light into this matter it would be really appreciated.

Many thanks in advance

No need to use PC mode. Just use normal hdmi mode. pc mode is only necessary when if you feel any lag while playing games, otherwise it is NOT necessary.
