But two displays? Using two cables (swapped for proper A/B comparison).
Recently, the main display ( NEC PA302W) also occassionally blinks (loses signal) also, but only for a moment.Īt first I blamed the PA322UHD display. It comes and goes, working OK for hours, then becoming unusable for 15 minutes at a time. But usually just a blink-off to no signal, then back, then off, repeatedly for several minutes. My NEC PA322UHD 4K display (critical to my daily work) has been on the blink, losing the signal, making crackling noises from its speaker (though not always), discolored image (intense magenta and/or green), mangled image, etc. SEND FEEDBACK Related: 2013 Mac Pro, 4K and 5K display, computer display, display connectivity, GPU, iMac, laptop, Mac Pro, MacBook, MacBook Pro, NEC, NEC PA302W, NEC professional displays, noise, Thunderbolt, video
