Ubuntu 16.10を実行している新しいコンピュータ（i5-7200U、Intel HD Grpahics 620がインストールされたKabylake）があります。
外部HDMI画面を使用してください。
何らかの理由でこれが検出されますが（「ディスプレイパラメータ」メニューに表示されます）、黒色のままになります（そうしないとモニターがオフになるため信号があります）。
職場にHDMI画面がもう1つありますが、何の問題もなく使用しています。いろいろなケーブルを使ってみましたが、画面はまだ黒です。
この画面は他のコンピュータ（Ubuntu 16.10、Hackintosh、Windows）で使用しているのでうまく機能します。
この問題を解決するために何ができるのかを少し知りません。どんなアイデアがありますか？
私の設定に関するいくつかの詳細は次のとおりです。

This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 1
No EDID on bus 2
No EDID on bus 4
No EDID on bus 5
No EDID on bus 6
2 potential busses found: 0 3
Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
256-byte EDID successfully retrieved from i2c bus 0
If this isn't the EDID you were looking for, consider the other potential busses.
Looks like i2c was successful. Have a good day.

モニターのメニューボタンを押してみましたか？ HDMI入力を選択するために使用します。
私は同様の問題があり、これを理解するまで完全に混乱しました。見逃した場合に備えて共有します。
