For example, your TV likely has HDMI 1.4 connections, which max out at 3,820x2,160-pixel resolution at 30 frames per second. If you've gotten a new 4K monitor, you're limited to 30fps.

HDMI is really best for connecting a PC to an HDTV. Consequently, I’d go with a DVI cable. That’ll give you a pure digital signal (VGA is analog) and a much sharper picture at higher resolutions.

Of course that wasn't good enough for me so I got a slightly more expensive adapter that converts to 480i/576i so I can capture that output using an HDMI capture card in the highest possible quality.

I have another device that outputs VGA and it does not have this problem- I get a nice clean 1360x768 image. ... I had similar issues with a Samsung TV and generally awful picture quality over HDMI.

Two of the most common video interfaces for transferring high-quality audio and video signals from an output device to a display are DisplayPort and High-Definition Multimedia Interface (HDMI).

Anker's HDMI adapter is designed for modern USB-C devices and can output 4K at 60Hz, giving you a great quality picture. It's built with a durable braided nylon cable that can withstand much use, too.
