Hi I just purchased a Pegasus J4. The performance is great and I am very pleased with it in that regard. Unfortunately I have a small problem when hooking up my DVI monitor via thunderbolt to dvi adapter. The chain is Macbook pro --> J4 --> External DVI monitor. The problem is that upon boot up, my mac switches (changes to a blue screen for a second) the laptop screen to the main screen, but then switches back immediately. It repeats this problem atleast 4 more times before it finally switches to my monitor and STAYS on my monitor. Is there any reason why this is happening? Should I do a firmware update? Thanks.
