I'm sure you have seen this many time before but the LED sync isn't working. I have a GTX 1080 FTW2 which is about 4 months old. Before before LED sync has been working perfectly until roughly 2/3 weeks ago when suddenly I cant change the colour of it. It is stuck to the previous preset colour of what I had before. It only stays that colour. I even uninstalled all of its content and downloaded the steam version. And yet no results. I can mash on the LED sync button as much as I can but nothing happens. not even the little window pops up anymore. Everything works but the LED sync. And yes is did verify all files etc. 
 
Any ideas? yay or nay?

I'm using X1 on a 2080 Ti and LEDsync was causing serious lag issues for me. I had to uninstall it.

I am having the same issues. I have the FTW3 2080. My LED only stays white one the front no matter what I do with the LED SYNC settings.

I just uninstalled the steam version and downloaded the stand alone version (6.2.3) where the LED SYNC is actually working. I don't over clock so its cool for now I guess.
