I have a 3-week old Sapphire R9 290 video card and a new ASUS VE278 27" monitor that I installed Friday. After gaming for a few hours without any issue, I started to watch a movie. As the movie was playing, and without any user input or changes, the monitor view changed to "letter" format. The desktop is visible but faded back except for the center "letter" view which is clear. The clear view looks like if a box with small sides was laid flat with a center square and 4 rectangles (1 on each side). I reinstlled Catalyst and have gone through every setting I can think of. Any thoughts?
