Hi there, newbie posting so thanks in advance for bearing with me.
I have the following simple set up:
2011 11' Macbook Air -> Monoprice Thunderbolt to HDMI adapter -> 10' 28AWG Monoprice HDMI Cable -> Epson Powerlite 8350
My problem is an intermittent flash/blink. It happens every 5-15 minutes, but has disappeared completely during some viewing sessions too. Sometimes in the flash I can make out what looks like bits of digital static (scrambles or a bar of green, like what I see when the computer and projector are first connecting). It always lasts for less than a second before continuing on normally. I don't use the hdmi for audio, so I don't know if it's cutting out as well.
I contacted monoprice to replace the TB/HDMI adapter, thinking that this was the issue. They replied that it was more likely the gauge of my 10' cable, and suggested that I get a 24AWG one to address the problem.
From what I've read around here, it seems like a 10' cable shouldn't be an issue, no matter the gauge. What's more, I'm having a hard time finding descriptions of problems caused by a bad/insufficient HDMI cable, and don't want to go through the hassle of buying a newer, more expensive cable, and waiting to test it only to find out that it's not my problem.
ETA: Also, this problem has recurred over two different Epson 8350s (I replaced the first one for a separate issue--a loose power prong-thingy...) so I think it's not a defect in the projector. I have also tried switching between HDMI ports on the PJ.
