Connecting two monitors

[strula]

What's the best way to connect my second monitor to my GTX 970 which only has one DP port. Should I go HDMI->HDMI, DVI-D to DP, etc...

Any way you want, it's all the same. If the port supports the monitor's resolution / refresh frequency, it's just as good as any other port that also supports the monitor's resolution / refresh frequency.

It can't be all the same. Some ports can display higher quality image then others. It says HDMI only does 30 hz while DVI does 60 for example.

But HDMI has better color depth???

Your monitor will have certain limitations, so there is a maximum configuration it can support. Any digital connection (DVI, HDMI, DisplayPort) which supports your monitor's maximum configuration will look identical to any other digital connection that also supports that configuration. For example if your monitor only supports up to a resolution of 1920×1080 at 60 Hz with 8-bit color depth, then your monitor's configuration is supported by DVI, HDMI, and DisplayPort, and they will all look identical.

Color depth depends on your monitor. DVI supports monitors with color depth of up to 8 bits per channel (24 bits per pixel). HDMI and DisplayPort support monitors with higher color depth than that, but if they are used on a monitor that is limited to 8-bit color depth they will look identical to DVI. Standard monitors are limited to 8-bit color depth, so unless you have a special professional monitor, there will be no difference between DVI, HDMI, and DisplayPort.

 

Image quality is exactly the same between these connections for any given configuration. The only difference is the maximum supported configuration. If your monitor's limits are within the capabilities of all three of them, all three will look identical.
