Ubuntu 18.04 text is blurry when I turn up the refresh rate
I'm using an Nvidia GTX 670 with the nvidia proprietary driver 690.
At 30hz All of the fonts look great, in fact everything looks great. However when I turn the refresh rate up to 60hz many of the fonts become blurry and blotchy. I tried using gnome-tweak-tool to adjust the anti-aliasing but no matter what I do the fonts are blurry.
Just a quick note, Im using a 43" Vizio 4K tv and I have the resolution set at 4096x2160. Also, using the same tv as a monitor for my 2105 macbook retina with the same resolution/refresh rate everything looks fine, so I doubt it's the tv.

GTX 670 surely does not support HDMI 2.0, so it cannot do 4k 60Hz 8-bit RGB.
It is possible that the driver tries to do YUV compression to allow 4k 60Hz over HDMI 1.4, which cause the blurry.
thats a great point! I totally spaced it that for the mac I used a thunderbolt to active HDMI converter which was the only way to make it work.
