Surface RT - Colors look like they're 16-Bit

[bentman013]

I've had my Surface RT since November and all of a sudden, my colors look like they're coming in at 16-Bit. Icons have shadows, there's some distortion, browns/blacks turn white - terrible. Solid color backgrounds are fine when they're pastel colors - the darker I get, the lines come back.

Nothing happened as far as I know (though I'd love to blame the mother in-law for looking at it) to the device; I've reset it both ways (apps/data and a full reset) to no avail. My laptop has an Outlook.com account that syncs, but that's been fine.

Has anyone seen this?

Thanks
