Text quality @ 4K60, differences in quality between NV and AMD?

You need a "premium certified" HDMI cable. That is the official branding. If it doesn't have the below orange logo then don't buy it. Monoprice has them at reasonable prices.

You don't need a premium certified cable. You need a cable that can pass a 4k signal through an 18gbps HDMI cable. If it won't pass the HDMI 2.0 signal, the cable will not work. If it can the cable will work. The 18gbps cable rating is what you should look for in the product description. Regular high speed cables will only pass HDMI 1.4 signals.

Incorrect. The HDMI standards organization is telling you exactly what to look for that is built for AND has been tested to pass 18gbps. Anything that doesn't have that seal is rolling dice. Given these cables cost about $1 more than non-certified cable, you'd be an idiot not to buy one.

I've run into a half dozen "18gbps HDMI 2.0" rated cables that simply don't allow 4:4:4 @ 60hz 4k, and as such I doubt they actually meet the proper HDMI 2.0 spec, but unless you're running 4k or 1440p 144hz, you'd never notice since they run 1440p 60hz just fine, or 1080p 144hz without issue.

Best to use Displayport 1.2 if available, which offers more bandwidth (DP 1.2 is 17gbps after overhead vs ~14.5gbps after HDMI 2.0 overhead), or properly certified HDMI 2.0 cables. No point saving a few bucks on a random HDMI cable when you can get certified ones cheap enough.

Yeah spending $400-$4000 dollars on a 4k display device only to save $3 on a cheap cable and have a bunch of troubleshooting issues is pretty silly to me.

I usually get my cables from blue jeans cables. They are close by (1 state away) and they sell quality cables.

My 4k monitor shipped with a short little displayport cable, not long enough, so I ended up having to get a 2 meter cable from BJC.

I think the total was like 16 bucks and that included shipping.
