dark shadow creeping in from one corner of my monitor

There's a dim, cloudy patch in the bottom left corner of my monitor, worse on white backgrounds. It's not on screenshots so it's not the GPU. Backlight bleed or the panel dying? The monitor is about three years old.

is the shadow also over the monitor's own on-screen menu? if it is, it's the panel, not the pc or cable. a dark patch that grows from a corner is usually backlight failing or pressure/moisture damage in that corner, and those don't fix themselves. check warranty now rather than later.
