As i use the same monitor (LG W2486L) on my Nintendo Wii U and my Computer, i never payed attention to the fact that sometimes i couldn’t see some colors just for a wrong calibration on my display.
I do use Adobe Lightroom on this PC to make enhancements to the photos, but how could i know if my display was showing what i need to see?
A friend of mine told me about some videos that could help me to do that, on the link below you can download the videos and check more information about it.
