HDR (High Dynamic Range) indicates how effectively the TV can reproduce the enhanced quality of HDR content. Some tests are also performed via the TV USB input. All video content is played through the TV's HDMI inputs.

Note: upgrading from a LTS release to a non-LTS release, such as from 12.04 LTS to 13.04, as the OP did, instead of going between LTS releases, carries a higher risk of bugs and associated troubleshooting.Models like the 55QNED85AQA are rated on multiple criteria, such as thoseĮvaluated using basic HD content (non-HDR). Look at the screen during boot and it may make a recommendation, or Google it on another machine, referencing your computer brand & model, if you can't figure out the key on your own) and make sure the new SATA port that you just used for the DVD drive is enabled or "on."Īfter this procedure, my DVD drive worked perfectly in the new installation, including being automatically mounted and visible in the desktop environment.

In my experience, this was a hardware issue. Although the question is 2 years old at this time, this answer is provided for completeness.
