お世話になります。シャープLL-M240のモニターを使用しているのですが、画面をスクロールした時の残像が気になります。設定で、視覚効果の「ドラッグ中にウインドウの内容を表示する」のチェックを外しても直りませんでした。その他に設定箇所等ありましたら教えて頂きたいです。

ECマスターズの田中です。画面に動きがあった時の残像感に関する解説、および対策が下記ページにまとめられておりますので、まずはご一読ください。 http://capricciosoassai.blog51.fc2.com/blog-entry-116.html モニターの機種によっては、同ページにまとめられている「動きぼやけ対策」の機能を持つものもございますが、 https://www.sharp-sbs.co.jp/display/monitor/ 上記ページの「24V型 LL-M240 取扱説明書」を確認したところ、この機種には、特に動きぼやけ対策用の機能は搭載されていないようです。

ご返信ありがとうございます。このモニターはこういった仕様ということなのですね…。承知いたしました。ありがとうございます。
