Depends on the adapter and source. You may find issues when playing HDPC protected content if you buy a low quality adapter.
DisplayPort to HDMI doesn't need an adapter since DP has an alt signal mode with HDMI support.
Although I'm not sure 2.1 signalling is available yet or not.
DP++ HDMI support tells the GPU to output HDMI. If the GPU can't output HDMI 2.1 over an HDMI port, it can't output it over a DisplayPort (as a general rule; you could theoretically wire the DP for a higher standard, but why would you?)
