I just picked up the Acer XF270HU and have never calibrated the colors of a monitor before. I found a collection of color profiles on TFT Central, but I don't know which one to use. Here are the color profiles: XF270HU_67Mon brightness_D65_160cd luminance.icm, XF270HU_79Mon brightness_D50_160cd luminance.icm, XF270HU_80Mon brightness_D65_250cd luminance.icm, XF270HU_100Mon brightness_D65_250cd luminance.icm, and XF270HU_100Mon brightness_D65_default luminance.icm. If anyone knows which profile I should use, that would be awesome. Thanks!
