Как отобразить полноэкранный кадр с разрешением, отличным от моего дисплея?

Я нахожусь в процессе обучения самому развитию DirectX, проходя все учебники по http://directxtutorial.com/. Я столкнулся с проблемой, которая, по моему мнению, связана с наличием нескольких мониторов.

Мой дисплей 1920 x 1080. Когда мой код работает в своем текущем состоянии, мой основной монитор становится черным с курсором в центре. Когда я устанавливаю свой SCREEN в верхней части моего кода на 1920 x 1080, моя программа работает нормально и отображает мой спрайт с темно-синим фоном. Когда я покидаю ЭКРАН, определяемый как 1440 x 900, и отключаю мой второй монитор, моя программа работает нормально. Это то, что заставляет меня поверить, что с моим вторым монитором что-то не так.

Любая помощь будет оценена!

Ниже мой текущий код:
