Maybe this will help you. Or you can try change contrast on led processor.

This sounds like the common full / limited setting with Nvidia cards.

Check Nvidia Control Panel > Select screen and check below if it's set to Limited or Full Range

As Angelo stated, 95% of the time it's your GPU outputting a Limited RGB range (16-235) vs a Full RGB range (0-255). This is used mainly for TV's as they don't typically need or process 0-15 in the dark range, for LED's though this is much more sensitive and is needed. Check your GPU settings for this.

The other 5% is when you're using junk signal flavor converters like BMD micro converters, that force a limited range when using them. The soluton for this is to use better hardware like Decimator or AJA.
