Keterangan
Kami menyarankan agar aplikasi menggunakan satu delegasi untuk menangani sebagian besar peristiwa tampilan karena dalam banyak kasus, perubahan pada setiap properti tampilan mengharuskan aplikasi menggambar ulang dirinya sendiri. Selain itu, banyak perubahan properti yang dihasilkan dari perubahan mode tunggal yang memengaruhi seluruh sistem operasi.
Sampel 3D Stereo Sederhana Direct3D 11.1 menunjukkan cara menangani perubahan stereo sistem.
