nvidia drivers problem

[bais444]

iam having a problem with nvdia drivers when i connect them to my tv via hdmi cable and try to change the resolution to native 1920x1080 32bit color depth.The result is like having a 16bit color depth.i have been having this problem for years and the only solution was by interferring with the drivers and copypasting the edid of my tv to the nvdia
drivers(http://rhymeswithtoaster.com/2013/12/22/how-to-fix-nvidia-blurry-or-fuzzy-screen-or-text-caused-by-driver-installation/)
is there any other solution iam missing?
i have contact the customer support service but they dont officially recognize the problem.
i have tried it on several motherboards and cpus both amd intel gygabyte and msi mobos

From a post on gforce forums I read a while ago

• 1. Go to "Nvidia control panel"
  2. Under "VIDEO" go to "Adjust Video Color Settings"
  3. Uner Point 2 select "With the NVIDIA settings"
  4. Go to "Advanced" and to your eyes will show tab called "Dynamic Range" where you can change it
  between "Limited" (16-235) and Full (0-255)
  I also ticked two other options below "Dynamic contrast enhancement" and "Color enhancement"

Are you using a recently updated driver when you try this?
