Color dull connecter

[lSupDude]

I have VC239H I currently connected it to DVI and i am satisfied with its color and quality now i've been researching about this monitor overclock then i tried it, in DVI it can only go in 65htz max and now i tried HDMI, which is the first time i connected it with HDMI and I notice just by the desktop that the color is quite dull? and after that I tried to overclock it and it can be overclock to 73htz, my question is why is DVI has better colors? and why is HDMI can overclock upto 73htz?
Thank you in advance guys!

Nope, same digital signal. Are you using an Nvidia card, by chance? If so, go to the NCP/Change Resolution and scroll down to Output Dynamic Range. If it is set to Limited, reset it to Full.
