PC用 4K 壁紙

PC用の4K壁紙は3840 x 2160ピクセルで、4Kモニターの解像度そのものです。多くのノートPCやモニターより大きいため、1920 x 1080のノートPCや2560 x 1440のモニターではWindowsが縮小して表示し、画像はくっきりしたままです。3840 x 2160の画面ではピクセル単位でぴったり収まります。このページのデスクトップ壁紙は3840 x 2160（16:9）で、一部は5K（5120 x 2880）もあり、すべてサイトから無料でダウンロードできます。ウルトラワイドモニター（3440 x 1440）は16:9より横長なので、画像の上下が切れます。主役が中央の帯にある絵柄か、画面全体を埋める抽象的な壁紙を選んでください。

FAQ

PC用4K壁紙の解像度はどれくらいですか？

3840 x 2160ピクセル、比率は16:9です。よくある画面は1920 x 1080（フルHD）、2560 x 1440（WQHD）、3840 x 2160（4K）で、どれも16:9なので、4Kのファイルなら切れずに画面全体を埋められます。Velpaperのデスクトップ壁紙には5K（5120 x 2880）のものもあります。

1080pのノートPCでも4K壁紙はきれいに見えますか？

きれいに見えます。ファイルには1920 x 1080の画面の4倍の画素があり、Windowsが縮小して表示するので輪郭もシャープです。3440 x 1440のウルトラワイドでは、16:9の画像が横幅に合わせて拡大され、上下が切れます。

Windows 11で壁紙を設定するにはどうすればいいですか？

画像をダウンロードし、設定 > 個人用設定 > 背景を開きます。「画像」を選び、「写真を参照」からファイルを指定します。16:9の画面なら、調整方法は「ページ幅に合わせる」が合います。エクスプローラーで画像を右クリックし、「デスクトップの背景として設定」を選ぶ方法もあります。

PC用の壁紙は無料ですか？

はい。デスクトップ壁紙はすべて4K、一部は5Kで、velpaper.comから無料でダウンロードできます。スマホ用の壁紙は仕組みが異なり、iPhone、iPad、Android向けのVelpaperアプリで短い任意の広告を見たあとに、2160 x 3840のファイルを保存できます。
