VGA adapter can't handle 1920x1080@60Hz ?

Hi,
I just found this sub forum so I'm reposting my problem into the proper forum if that's ok.
I bought an Air two days ago with a VGA adaptor, for use with an iiyama 24" VGA monitor.
When I set the monitor to its native 1920x1080@60Hz resolution, I get fast moving zig zag disturbance all over the screen that quickly comes and goes, continuously.
I've tried a different VGA cable and even a different VGA monitor (an HP 2007w). Both monitors have the problem, and only at 1920x1080. When I set either monitor to a lower resolution, the disturbance goes away. Of course I want to be able to use my iiyama's native 1920x1080 resolution.
Any ideas? My guess is that either the SVGA adaptor or the Air's graphics chipset is flawed in terms of driving VGA monitors. I hope I'm wrong.

I have a similar problem with my new MacBook Air 13" w/ 4GB, 256GB SSD, and a 2.13Ghz uP running OSX 10.6.5
My MacBook AIr is attached to a 24" external monitor (same monitor my previous MacBook 13" was attached to) and whenever there is heavy activity on the SSD the video image starts to shimmy, shake and tear. Within seconds of the heavy SSD activity stopping the video returns to normal.
It doesn't matter what the video resolution is set for.
The issue is easily reproduced (on my machine) - start a Time Machine backup, a SuperDuper backup, or any large data transfer.
It's not the monitor as I can attach two computers to the monitor and 'split' the screen. Only the half of the 'split screen' showing the MacBook Air 'shakes' and 'shimmies'. The other half of the 'split screen' is rock solid stable. I've also tried two other monitors... same results.
The MacBook's own screen does not exhibit the problem.
So it's obviously related to the external video path.
Spoke with Apple support and they claim to having never heard of the problem. Yet other folks have reported a similar problem (though not mentioning what triggers the issue) in other support forums.

  • Satelite A200-1IW: Win 8 - ATI Radeon HD 2600 can't set 1920x1080 @60Hz

    Hi!
    I have a problem with my Toshiba Satelite A200-1IW and its resolution on VGA 22" monitor.
    I decided to switch win7 to win8 and got stuck on this annoying issue.
    I can't set 1920x1080 @60Hz on win8 even though there was no problem doing so in win7 (I just had to uncheck the "list all modes" field and then choose 1920x1080 @60Hz from the list).
    Now, I only see 1920x1080 resolution @23, 24, 25 and 30Hz.
    None of which is working for me. A
    Any idea how to fix it?

    If you dont disable the option called: Hide modes that this monitor cannot display.
    Then you will get a whole list of modes which are not fully supported by display.
    In such case the display can be damage or affected.
    I think this might be one of the reasons.
    Send reason: the Win 8 is not official on the market and I assume some graphic card drivers would not function properly.

    What VGA adapter can I use with older MacPro?

    One way to find this information:
     menu > About This Mac > (More Info) ...
    ... in the header on on the right side click "Overview" and cut and paste the information there, BUT remove your serial number before clicking (Save Reply) on the forums.
    _OR_
    ...on the right-hand side of the header click "Support".
    In the lower half of the window that opens click "Specifications".
    cut and paste the heading of the article that opens, such as:

  • USB wifi adapter can only handle one request or socket at a time

    I have a usb wifi adapter that I bought recently.  The strange thing is that if I'm doing only one thing that is using the network (e.g. downloading a file) it works good and fast. But say I'm downloading a file and I do ANYTHING else that uses the network (e.g. just opening a browser at google.ca), the download comes to a stop. Then if I close the browser, the download starts up again a couple seconds later, good and fast.
    Another example is, say I'm in a Google Hangouts (video chat) session. As long as that is the only thing I have running, the chat works fine. If I open a second browser window, then the chat gets super choppy and pretty much un-usable until I close the second window.
    So basically it seems like I can have only one open socket at a time, or else it can handle only one request at a time. Also, most webpages open very slowly as a result because the browser only seems to be able to download one static file at a time (e.g. js and css files needed by the page).
    I'm sure it's a problem with the usb wifi adapter because I didn't have these problems when I was on a wired connection, and I have other devices using wifi (e.g. laptops and tablets) that don't have this problem either.
    Rather than paste a bunch of output from commands, please kindly tell me what to run in order to gather any useful info.
    Thanks,
    Edit:  The adapter is an ASUS USB n-53 (N600).

    I was exploring the CD that came with the device.  Turns out there are Linux drivers on it.  I didn't install any drivers, as wicd detected it automatically.  I'm wondering if changing drivers might help.  Can someone help me interpret the installation instructions?

  • If I buy a HDMI to VGA adapter can I watch sky go from my iPad

    If I buy this adapter will I be able to watch Sky Go from my iPad through my Apple TV? Because it doesn't support HDMI out put?

    No, AppleTV doesn't support cabled inputs (other than ethernet, I beleive).
    Assuming SkyGo supports it, and you have the iPad and AppleTV on the same network, you can use Airply to mirror the iPad to the TV.(http://www.apple.com/support/appletv/airplay/). However, many streaming video apps do not support Airplay (by vendor design).

  • Mini Display Port to VGA adapter with Mac Pro

    Just as a word of advice if you're thinking of buying a new Mac Pro and planning on hooking it up to dual VGA displays at their native resolutions - don't.
    Apple claim it will support 3 VGA displays. That might be true in a very loose sense but not in the sense that you'll actually be able to work with it.
    My experience (all using same adapter, cables and monitors):
    *Mac Pro - Dual screen set up*
    1 x LG Flatron W2242S connected via DVI > VGA adapter - offers native resolution (1680x1050)
    1 x LG Flatron W2242S connected via Mini Display > VGA adapter - does not offer native resolution
    *Mac Pro - Dual* screen set up*
    1 x Iiyama E2472HD connected via DVI - offers native resolution (1920x1080)
    1 x Iiyama E2472HD connected via Mini Display > VGA adapter - offers native resolution (1920x1080) but displays it pillar boxed (i.e. squashed)
    *MacBook Pro - Dual screen set up*
    1 x laptop screen - fine (obviously)
    1 x LG Flatron W2242S connected via Mini Display > VGA adapter - offers native res (1680x1050)
    The conclusions being that despite having the exact same configuration in terms of adapters and monitors my £3k Mac Pro is incapable of doing what my MacBook Pro can.
    I have spoken to Apple about this and they have admitted it is a limitation and suggested buying DVI monitors along with the Dual Link DVI adapter (£70).
    Not ideal.

    DVI-I provides the direct Analog signals needed to get VGA using a very simple adapter.
    DsiplayPort (and its Mini variant) requires a converter to produce VGA or Dual-Link DVI, and the converter must be active/powered. There is a lot of logic in those converters. It may also have additional limitations.
    In general, you should hook your highest resolution, most demanding display up with the DVI to VGA adapter.If running two Mini DisplayPort displays, ALL MiniDisplayPort converters must be active/powered.

  • VGA Adapter and 1920x1080

    I have an odd problem with my 2011 MBP (15").  I use an external monitor (Samsung SA350, identified as SMS23A350H by the mac) hooked up to a KVM switch using the VGA port.  The display support 1920x1080@60hz.  It gets detected as such, and everything works fine when I close the lid and only use the external monitor.  However, when I open the lid and try to use both displays (mirroring off), the content of the external monitor is compressed -- There's about an inch of black on the left side of the monitor, and a half inch on the right.
    The thing is, all of the content is displayed -- it's just shrunk down to a smaller size.  The MBP thinks it's running at 1920x1080.  About the only difference I see between the bad setup and the good one is that the monitor identifies its signal as "67.4khz 60hz NN" vs "67.4khz 60hz PP".  I don't know what NN and PP mean, and Google is little help.
    It's not the cable or the KVM switch, since it works correctly with the lid closed.  It also works correctly using a DVI adapter instead of the VGA, even with the lid open.  The same monitor/cable/KVM setup worked fine on my old (2008) MBP.  Has anyone seen this before?

    If you are showing a "non-plug and play" monitor in the Windows device manger, I would guess is a problem with the "DDC-EDID" communictaion link between the computer and the monitor. Either the monitor isn't reporting, the computer isn't reading, or the link (cable) is damaged. If you have another monitor and/or computer and/or VGA cable, try swapping them around to determine where the issue is.
    Examples...
    1) HP Elite H8-1240t with different monitor
    2) HP W2371d monitor with different computer
    3) Repeat 1 or 2 with a different VGA cable
    4) Try a different DVI-to-VGA dongle adapter with the HP Elite H8-1240t and HP W2371d monitor
    5) Try a different VGA cable with the HP Elite H8-1240t and HP W2371d monitor
    6) Try a different DVI-to-VGA dongle adapter and a different VGA cable with the HP Elite H8-1240t and HP W2371d monitor
    If you can't identify the issue from the steps above, you may wish to manually set the Windows resolution to 1920 x 1080 and set the refresh rate to 59 or 60 Hz.

  • My MacBook screen is stuck in "presentation" mode after using my "Mini DisplayPort to VGA Adapter." How can I fix this?

    My MacBook screen is stuck in "presentation" mode (I don't know the correct term) after using my Apple Mini DisplayPort to VGA Adapter - meaning the screen fonts and windows are larger than usual. How can I fix this? I've changed the display settings to modify it a little, but it still doesn't look right. I reinserted the adapter numerous times and restarted my computer, it still hasn't worked. Help!

  • Can't get the DVI to VGA adapter off my mini

    I have my Intel Core Solo Mini listed on eBay, and the one problem I have is that when I put the VGA adapter on (the Apple included one) i apparently cranked it down too tight and I can't get it off. For 99% of the customers that wouldn't be problematic because they're using it on a standard monitor anyway. But I have had a question from at least one person who uses DVI so not being able to remove the adapter might be important. Anyone have any suggestions for another way to remove the adapter? I don't care if I damage the adapter-I'll replace it. but I'd like to remove it as a stumbling block to a buyer.

    sorry to bother you-I figured out what was wrong and got it off. And am feeling pretty dumb about it.

  • How long can the Mini DisplayPort to VGA Adapter last?

    Hi,
    I've been using Mini DisplayPort to VGA Adapter (genuine) for a year now but not everyday. Yesterday I bought a new display that needs this adapter, so now is the time that it will be used everyday. I was wondering how long can it last (or operational hours) if it were to sit in the same place, not unplugged, with an average use of 4 hours a day?
    Thanks
    PS. This one: http://store.apple.com/us/product/MB572Z/B/mini-displayport-to-vga-adapter.

    This is impossible to predict.
    Sometime cables last a lifetime, sometimes they fail in short order.

    Can you configure an extended desktop with an external monitor (20") displaying full portrait mode (1200 x 1600 resolution) and keep the built-in display in landscape?
    I'd like to see something like

    Yes, I can't see why not.
    Just give it a try and report back if you have a problem.

  • Can't connect MBP to LCD projector using DVI-TO-VGA adapter

    I am trying to connect my MacBookPro to a Hitachi CP-X885 projector, which I normally connect an IBM Thinkpad to at 800x600 or 1024x768. I also use my MBP and the VGA adapter to connect to other LCD projectors and monitors (so my adapter works, as well as both systems, projector, cables, etc.). Problem is, that when I connect my MBP to the projector (I have to connect it via VGA as there is a 250 foot cable that goes to the front where the rear-projection takes place). When I do the "detect displays" nothing is detected. I also connected directly to the projector using a shorter cable, same thing (doesn't detect it). So, is the projector not supplying some type of signal to the output, that the MBP wants to see?)... is there a way to FORCE the MPB to have output? I know that if there is signal, it will display (we have LOTS of notebooks that display to the projector just fine, BUT have SEVERAL MBP's, and NONE of them will detect, and we've tried several adapters (just to be sure)... HELP!... is there some way to FORCE output from the MBP instead of it having to DETECT IT???
    Thanks!

  • IPad 4 lightning to vga adapter, works but gets stuck in video out mode. I can't get it to switch back to mirroring without restarting it

    I have an iPad 4 with an Apple lightning to vga adapter. (A1439)

    But if I do show any video on it, e.g. full screen a video from within Chrome, Safari, the apps for Youtube etc.
    or if I do a presentation using Keynote, it locks into working as an extended second screen.
    It shows the controls for the video on the iPad and the video on the external screen, which is what I would expect. But then if I exit the video or complete the presentation, the external screen continues to show the last frame of the video or presentation. Even if I close the app.
    I can't get back to using it in mirroring mode without shutting it down and restarting.
    Surely I am just missing something.
    I've tried force closing the apps that I use, switching between them, starting up new ones etc.
    But no luck.
    There doesn't seem to be a setting anywhere that I can change.
    Any suggestions?

    The same thing happened to me. After the big update, I also experienced exactly what you described. I ended up restoring the ipad a number of times.
    The first few times, I restored from a back-up. The last few times I have restored the ipad as new. It would work the next few times I turned the machine on, and around the third time, it would lapse back into the recovery mode, with
    the image of the serial cord connecting to an i-tunes logo on its desktop. This morning, I restored the ipad as new, but only allowed the apps manufactured by Apple to be synced back onto the ipad. I have powered it back on about three times, and so far, so good. I am waiting to see what happens the next few times I turn the machine on.
    I had a very helpful senior Apple express advisor help me on Sunday to do the restore as a new ipad procedure. He said that if that did not work, the next step was having it serviced. He also mentioned that often the third party apps have problems due to getting corrupt and this often happens after a major update. That is why I thought i'd try and see what would happen if I only synced the Apple apps back onto the ipad.
    It is not good though if I can't put third party applications on it without having the problem of lapsing into recovery mode, so I may have to get it serviced. I am wondering how many others have had this problem after the big update last week? Also, has anyone who was an early purchaser and got the flat-rate unlimited data plan subscription from AT&T, had to have their ipad replaced? Was there a problem with AT& T still allowing you to continue your special subscription plan?
