VIEWSONIC HDMI NOT WORKING MAC UPDATE

I highly doubt this is the case.Ģ) More likely there will be some sort of software/firmware update to address the issue. I have a feeling that one of two things will happen:ġ) If it is hardware it's probably a systemic issue which would mean you would have to wait until the next 'round' of MBPs comes off the line that have the issue fixed. While I can't say for sure until I hear back from the engineers today or Monday, my guess is that it's not faulty hardware so returning the MBP won't do any good. Yeah I agree that it's annoying, but it's new tech and there are always probs with stuff like this. I'll try Thunderbolt -> DVI -> VGA next time and see what happens.

I hope there is a way to get some king of generic DVA out to the projector set-up, whose arrangement is ultimately outside of my control.

(I was flustered in front of a restless classroom - yes, i shoulda done a dry run in advance.)īack in the office, trying Thunderbolt to DVI to an Asus desktop monitor works like a charm. I didn't get a chance to check System Profiler to see if anything was visible there. On my new MacBookPro 2011, connecting via Thunderbolt port -> VGA, my first attempt to detect display froze Displays preference (I had to force quit System Preferences), whereafter further attempts detected nothing at all.

I have no idea how all this is wired, but on my old MacBook Pro (late 2006), I just connected via a DVI -> VGA adapter, hit 'detect displays' and it all worked. I teach in a classroom where a dangling VGA cable connects first to a switch, then a desktop monitor, then finally a ceiling mounted projector for presentation that mirrors the desktop monitor. Hopefully a fix for this comes sometime soon. I have no idea what exactly is going on here but it's clearly something strange with the thunderbolt port itself (some sort of power issue).īTW- i've tested both HDMI & DVI to mini display cables and get the exact same results. If i then unplug/plug the external monitor's power cable, once it starts back up i can see the login just fine. If i sleep the MBP and just leave the monitor on and then wake the laptop, i get no response from the external monitor (in mirrored mode or extended). If i remove the mini display cable i can then turn the external monitor off manually using the displays 'off' button. I have to unplug the monitor's power cable to get it to turn off. If i try to manually turn the external monitor off it simply will not turn off if i leave the mini display cable attached. Once i've got the external on i can use it without a problem, but as soon as i sleep the laptop, the external monitor stays on (it used to go into sleep mode). I can get the monitor on after some fiddling (using the normal macbook external monitor 'tricks'), but it doesn't work smoothly. What happens to me has something to do with the ThunderBolt port itself. It does not work like it did just yesterday with my old macbook. I'm able to get my external monitor to work on my new macbookPro 13' (early 2011) but the functionality is funky. I'm having a similar problem (posting here in case it helps someone and also in hopes the apple engineers get wind of this issue eventually).
