HDMIが機能しません。

私は古いラップトップをメディアプレーヤーに変えて新しい命を吹き込もうとしています。これは古いHP DV7であり、Lubuntu 17.04を実行しています。

lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 17.04
Release:    17.04
Codename:    zesty

HDMIがうまくいかずに動作しようとしました。別のノートパソコンでテレビをテストしましたが、HDMIが正常に動作します。このノートパソコンはHDMI経由で問題なく24インチモニターに出力することもできます。 LCD画面の解像度もノートパソコンに接続すると、見える領域を離れるのにどこで解像度を変更するのかわかりません。これは、xrandr - - ノートブックが接続されたときの電流の流れです。

また、画面を外部/ミラーリング/などにする方法を把握できないようです。通常のfn + f4が機能していないようです。
