No, it's not too good to be true, I have found a way to make everyones game look even better, not to mention everyones pc's too.
Nvidia has acknowledged that HDMI users have not been getting the "quality" they deserve. Apparently it's something with the code they use for the Nvidia drivers. People that use both Nvidia and HDMI are not getting full RGB range of colors.
Until now, (well, a little while ago) There is a quick "patch tool" that corrects the driver mistake and fixes this "problem"
It's not a gimmick, it's not a virus, it's real.
It looks amazing, my setup already looks great, but after using this tool, I swear my 40" looks like AMOLED now, I'm not even kidding. Colors are more vivid than they were before, blacks are more black, whites are more white.
So, Here's the link, enjoy!
