Having updated my laptop, I am experiencing great difficulty with Lightroom 5. On my old laptop (with Windows 7) it appeared to work great and when I edited pics and put them on social media they looked the same as on my computer. However, I have now transferred my Lightroom to my new laptop and when editing pics, they look great on my computer. However, once uploaded to social media, they look yellow and terrible. What on earth is the issue? Is it an issue with Lightroom or my computer? I spoke to someone re computer and they seemed to think a compatibility issue. My new laptop has Windows 8.1. Can someone please help?
