Intel N100 spec sheet [1] says it's limited to 4K@60Hz and this seems confirmed by a few Reddit comments. If you're using the N100 for display output, are you sure you're not running 1440p@120Hz?

I have a whole thread over on Reddit about it, the spec sheet is wrong - but you must use displayport.
