Where can I find a standalone light sensor that updates the brightness of my screen to match the ambient light level in realtime for Windows 7? My monitor does not have a sensor. I had the idea there was such a thing, but all I can find is for laptops or Macs.
Check this before buying somethings, May be it's a solution if there's no such sensors built-in your PC...
Hope this help. Let us know. :)
