Monitor issues with Macbook Pro and Thunderbolt

having issues getting my HP 2311 monitor to work on thunderbolt cable to DVI, help?
It keeps freezing computer, or going blue screen.

Concerning this comment:
I know that neither the adapter nor the VGA cable have a problem since I connected the computer to my 1080p TV and it worked just fine...
I would like to point out that 1080p has a lower pixel clock than will 1920 x 1200. So it could be the stability problem is only present when the pixel clock is at the high end of the range.
You could return the adapter and try another. A new one might have better margins. Another thing you could try is to use a utility like SwitchResX to lower the pixel clock and see if stability improves.

  • Issues with MacBook Pro and Asus VW266H

    I own a 2.4 GHz 15 inch MacBook Pro,and an Asus VW266H (external monitor) that I wanted to connect to my Mac via VGA,since the DVI is connected to my desktop computer.So I went ahead and purchased Apple's MiniDisplay Port to VGA adapter,and connected my Mac to my display.At first,the Mac didn't recognize the display with its name and would only go up to a resolution of 1920x1080(while the maximum resolution of the display is 1920x1200). I restarted the Mac with the display plugged in,and once the laptop booted up,the resolution was 1920x1200 and the display was recognized, but immediately quite a lot of trembling was noticeable.When the display wasn't detected properly(as an Asus VW266H) this problem wasn't present. I'm guessing that this is a compatibility issue,which by the way wasn't fixed by the latest EFI update by Apple,which improved external display compatibility. Does anyone have any idea if the problem might be something else other than lack of compatibility and/or how to fix it?

  • Wireless Router issues with MacBook Pro and Windows XP laptops

    hello,
    I have a d-link wireless router and I have a MacBook Pro and a Windows XP laptops. My issue is that I have to keep rebooting either the router or the modem (which I both replaced) and it still does not work right. Now can mac and windows work simultaneously through a wireless router (d-link) with no issues?

    My problem is that every time I log off either computer, and when I start it back up up again I have to reconfigure all over again for both laptops to get connected to the internet. I called the d-link people and they pretty much said if i still had problem to go their web sites and download their firmware (which I have that version) so I am running out of options because I just can't turn either of them on with out reconfiguring it. Now I am using WPA on them. Could that be the issue? But right now I do not know. This is my first mac and I am getting a little irritated by this. Overall I like the mac except for this little issue. Does that help?

  • Having issues with MacBook Pro and Verizon Mobile Hotspot

    Hey everyone,
    I bought a MacBook Pro with the Lion OS. I recently switched to Verizon and got an HTC Thunderbolt so I could use it as a hotspot at home and when I travel.
    The problem I am having is when I turn the Mobile Hotspot on is, it will connect and stay connected for anywhere from 2 to 10 minutes and then it will work intermittently after that until I turn it off. I've talked to Verizon Tech Support probably 30 times in the last 3 months about the issue. They sent me another SIM card and a new Thunderbolt at first. The issue did not go away, so they offered me a Samsung Charge. Got it and it did the same thing. So I told them to send me back a Thunderbolt, because its a better phone and the Charge was too glitchy.
    I've been to the Apple Store twice now and they dont know why its happening either. The only thing that has remained constant throughout this whole troubleshooting process has been my MacBook Pro. My questions are: Is anyone else experiencing this type of behavior? and What could possibly be causing this issue?
    Im a new Mac user, so Im not sure how to troubleshoot issues like this, or if there are compatibility issues Im not aware of.
    Thanks for your help,
    Matt

    Hi Matt,
    Did this ever get resolved for you? I have the exact same problem except I'm running Snow Leopard on a MacBook and my phone is a Droid Incredible 2. When I use the hopstpot from a ThinkPad running Windows 7 or a System76 netbook running Linux Mint it works perfectly. But when I try to use my MacBook it connects for, like you said, anywhere between 3-10 minutes and then connection is intermittent and super slow. I haven't gone through the motions of contacting Verizon yet...
    Thanks,
    Aileen

  • Issues with MacBook Pro and ACD 30"

    Does anyone else have a 30" ACD hooked up to their MacBook Pro yet? My 30" is having some issues with my new MacBook 2.0ghz and I would like to see if I am the only one.
    #1) I am getting horizontal white lines flickering every minute or so. This does not happen on my 17" PB G4 1.67. This is more distracting than the "dancing pixel" problem.
    #2) The bottom of the reflection of the album art in FrontRow is distorted when I use the 30" as the main monitor. I posted a photo here: http://members.cox.net/5337/fr.jpg - the "distortion" changes everytime I change song and it different everytime. It occurs on all the album work.

    I think you were responding to Bob Smith, but regardless, I found the same information.
    One thing I've noticed, and mind you, I don't have my MBP yet, so I'm working from photo's, but I am bothered by the DVI connector being so "exposed". I would have somehow put a sliding cover on it, or at least one of the plastic end caps. I know, I will most likely never use my MBP on an external display, HOWEVER, I don't like the idea that all sorts of gunk and stuff can easily get jamed into that big ole connector!
    I think an air can or a fine photo brush should be part of your "kit". Just my opinion...

  • Issues with Macbook Pro and Lion

    Hi Folks,
    Since I upgraded to Lion I have been having issues with Lion/Macbook Pro.
    On occassions whilst using my magic mouse the mouse will start highlighting everything, neither left or right clicking will alleviate this. The only option I have is to go to the Apple menu and right click to reveal it (left click does nothing). I then have to right click on restart which produces the restart window, I then have to press "enter" to reboot the Macbook.
    This issue originally started with 10.7.2 and I was hoping 10.7.3 would cure this issue, unfortunately this is not the case.
    I have tried using a Logitech wireless mouse to see if it is an issue with the Magic Mouse but the same happens.
    One issue which I have noted on the forums is that Lion does not like external monitors and I use a Dell 2209WA with the Macbook Pro in clamshell mode but not sure if this may have any link.
    I have tried everything I can find on the forums but to no avail and would be very grateful if anyone out there had similar issues or better had found a solution.
    Many thanks,
    Iain

    Your understanding of the problem seems correct to me. There's no way to fix it except to replace the logic board.

  • Issues with Macbook pro and siemens gigaset se587

    Hello!
    Wondering if anyone can help me with this issue;
    Bought my macbook pro about a year ago as a refurb off the apple site, everything works fine with it up until about a month ago, when the wireless internet kept dropping out and required me to type the passcode back in to gain access (I thought this was wierd as it is supposed to remember this info).
    The next stage of this was the router disapeared completely off my airport list, after navigating through the forum pages I found that broadcasting on a different channel usually works, it was on 13 I dropped it down a couple and we had wireless internet once again.
    As of recent, my router seems to of randomly reset itself after speaking with TalkTalk we got it back and running... but only on the PC. The element that had changed on the setup was (I may get this wrong) the router was pppoe and not pppoa (im not clued up on wireless networks an lingo, but I hope it provides some insight as to what happend).
    The problem now is my macbook can see the router but the passcode (from the bottom of the router) does not work, everytime I type it in I get 'connection timed out' and it only works with a wired connection.
    I hope I have provided enough info for you guys to help me out. I will be very appreciative of any insight you can offer.
    Thanks in advance

  • Wireless connectivity issues with Macbook Pro and At&t service HELP!!!!!

    I have three Computers two PC's and one Macbook Pro( the latest model).My desktop PC is used by ethernet, my girls laptop is used wirelessly and finally my MBP was being used wirelessly.
    I started off with only the two PCs and my internet connection never had a problem and I was doing everything from: on the internet to downloading.
    Before I bought my MBP I had also switched from internet and phone bundle to just internet from At&t service. So when I got my first MBP I notice that I was loosing wireless connection with both my girls pc laptop and my MBP so i thought it was because I had just switched service, though they send out a service technician and we came to a conclusion that it was the MBP. (I was loosing signal via wireless and ethernet). So we tried to see if both my girls laptop(wireless) and my PC desktop (ethernet) would run into the same issue which it did not.(MBP was turned off)
    So I decided to go my nearest Apple store and let them know what was going on. So I told them what was going on and they said It must be the airport card, and they ended up changing it. When I get home I discover that not only I am having the same issue but other issues too. I went back they ran some diagnostic and they said it was defective and they gave me a new one few days later.
    So in the mean time that I waited for my new one to arrive I used my PC desktop and my girl kept using her laptop and guess what no issue what so ever for one whole week. Now I receive my new MBP(they bumped the specs a little), went home set it up and still the same issue though I dont have the issue when Im using via ethernet. Just a view minutes ago I tried removing the ethernet and using the airport/wireless and within a few minutes I lost the signal.
    I have the gateway 2WIRE model(2701HG-B) modem/router.
    Is there something wrong? what do I have to do to make this work?

    Hi Guys, I bough my Mac almost two years ago. All this time I have experienced the same issue. There are tons of discussions re this issue in the internet. Unfortunately, Apple has done nothing to fix it. I have tried a lot of different options, but they work no longer then 1-2 days. The official fix - does not exist so far. It is quit strange, isn't? I can share my experience: if you go to AirPort Utility - Manual Setup - Wireless and then change Channel, it could help you till the moment you restart your computer; next time you need to repeat it again. It takes 2 minutes. Not sure that it would work for you but you could give it a try. Well, not the best option. Anyway Apple must fix it asap! Hello Apple, do you hear us? Good luck.

  • Connection issues with MacBook Pro and DVI to component video

  • Issues with Macbook Pro and Analog TV

    Hey all,
    I've got a VGA converter so I can use the Apple Mini Displayport to VGA adapter to connect my 2011 Macbook Pro to a 28ish inch Panasonic analog TV. Initially, the computer wasn't detecting the TV at all, so, on the advice of the internet I reset the PRAM. Now I do have a picture, it's just absolutely horrible. The image is in black and white, is constantly scrolling quickly across the screen vertically, and is flickering. I updated my software and restarted, but to no avail. I'm not sure where to do from here, and would love help from someone with some actual knowledge (I'm pretty decent with computers, but mainly because I'm able to google stuff and just follow the directions - couldn't find anything so I'm at a loss).
    Thanks in advance, and let me know if you need any more info from me.

    I had this problem earlier and was able to solve it by checking the display setting in the System Prefrences. This link will help you. http://documentation.apple.com/en/aperture/usermanual/index.html#chapter=B%26sec tion=4%26tasks=true

    Hi ..
    Shift key boots into Safe Mode, not Recovery.
    This only works on a Mac running v10.7 Lion or later.

  • MacBook Pro and Thunderbolt Monitor

    Hello,
    I have a MacBook Pro and a Thunderbolt Monitor. The Lion and the Windows7 operating systems are installed.
    My questions are:
    1. Why I can't use the Thunderbolt display if I don't connect the MagSafe power which comes from Thunderbolt monitor to the MacBook? But it works with Windows7 while the MagSafe power isn't connected to the MacBook.
    2. If I have to connect the MagSafe power to use the Thunderbolt display with MacOS Lion, is it harmful for the battery in the MacBook Pro? (I mean overcharging).
    Thank you very much.
    Sincerely,
    Selcuk Kiray

    As Kappy said Windows has no power management capabilities for Mac. Secondly Your MagSafe Adapter and battery has been built so that it knows when it's fully charged. After it's charged, it will then become a power cord until, you un-plug it, use up the battery and need to charge it again.

  • HT5219 Can I connect my thunderbolt monitor to my MacBook Pro and iMac at the same time

    I am wanting to connect my thunderbolt monitor to my MacBook Pro as a secondary monitor when running programs in windows 7 thru boot camp, and also have it connected to my iMac as a secondary monitor when working thru apps on my iMac. Is there a way to do this without having to connect and disconnect cables each time I want to switch.

    I don't think it can be done without a KVM switch, & not sure they can handle that resolution.

  • External Monitor blurry with MacBook Pro

    Good day, I have searched the forums but have not found a solution to my problem...
    I recently purchased a Dell 2005FWP External Monitor and plugged it in (DVI to VGA) to my MacBook Pro. It automatically adjusted to a 800x600 resolution which of course is not ideal. The menu gives a long list of display resolutions but most of them are "not available" when I click on them. I have tried switching the docks and the monitors to the opposite sides on "Arrangement" of displays but I still don't get a different menu. I can't seem to find the menu of resolutions for the MacBook Pro either.
    Please let me know what I am doing wrong...Sorry, I know I am clueless!!
    Thank you!

    I have a ViewSonic VX2035wm display connected to my MacBook Pro - the image on the external monitor shows ghosting and double images like we used to see on old tube TVs.
    Here is a post from MacFixIt.com that details my problem.
    http://www.macfixit.com/article.php?story=20081020231611468
    Late-2008 MacBooks: Image problems on external displays with mini-DisplayPort converters
    The new MacBooks and MacBook Pros come with a Mini-DisplayPort adaptor for external video, and Apple supplies various adaptors (DP to DVI, and DP to VGA) to accommodate current monitors. Some users are having difficulties with their adaptors when connected to certain monitors.
    Apple Discussions poster Ocell writes:
    "I have the exact same problem with my Viewsonic VG2030wm 20" LCD. I've ruled out bad DVI cables. The Macbook Pro works with my 12" Cintiq's display, and the Viewsonic works with my Intel iMac, so the video out/mini displayport adaptor/dvi cable/viewsonic display are all operational. It's just the specific combination of the Macbook Pro and Viewsonic that doesn't work."
    This problem has been found to frequently occur with DVI adaptors attached to their computers, however it has also happened with users connecting to the VGA adaptors. In these cases, unlike the DVI situation where no signal gets through, users have noticed the screen blinking or shutting off at random times. While drivers may definitely be suspect, the problem appears to be hardware-related since users have experienced the issue both in Mac OS X as well as in Windows via Boot Camp.
    The DisplayPort connections used on the new MacBooks have slight differences in their protocols than other connection types, which allows for expanded functions in smaller connectors, but also can run users into difficulties, especially when older connetion types are used. While there could be software involvement in this problem, it sounds like there's most likely a firmware-related problem that hopefully can be patched by Apple, or at least be accommodated for in a driver update.
    Things to Try
    Reset the monitor to defaults If there is a method for fully resetting the monitor, try doing that first. Most have a menu option to reset to factory defaults, but in addition there may be a way to fully reset the device such as unplugging it for an extended period of time. This information may be available on the manufacturer's website, or users can just try unplugging the device for an extended period such as 20-30 minutes.
    Toggle various monitor setups In the "Displays" system preferences, toggle desktop mirroring on and off to see if the monitor is not just extending the desktop to the second monitor. Especially if users have black wallpaper on their desktops, secondary monitors that are just serving as extended desktops may appear to be off when connected. Alternatively users can try dragging documents off the sides of their main monitor to see if they go over to the second monitor.
    Reset the computer Users might try resetting the computer's PRAM (which does contain some graphics parameters) by holding the options, command, P, and R keys down at bootup until the computer resets and makes the boot chimes again. Release the keys and allow the computer to boot normally. Additionally, users might try resetting the computer's system management controller. Here is an Apple Support article on how to do that.
    Use a different monitor Unfortunately, with hardware problems such as this users will not be able to do much, so if another monitor is available that works then users should switch to that.
    Try another adaptor Many monitors support both VGA and DVI inputs, and there is potential for users to get things working by using another connection type. Additionally, while it may be a long shot, users might also try chaining together various adaptors. For instance, users might try going from displayport to DVI, and then using a DVI to VGA adaptor as the next connection, to see if that somehow sends a proper signal to the monitor.
