IMac 5,1 20" external display options

I currently have a mini-DVI to HDMI adapter and a 20" 1080i TV, and they work albeit the screen is hardly legible in terms of type when I connect the two. I'm considering getting a 1080p monitor or TV to replace it to get the sharpness of progressive display and I want to make sure I get a wide screen ratio. I don't need colormatching. What 20" display/tvs have a VESA compliant back mount and HDMI and 1080p compatibility that won't be any harder to read than the display on my iMac 5,1 (the white Core2Duo).
Thank you.

Hi AB
While I can't speak for the Mini-DVI to HDMI and HD TV setup, I can say that I also experienced poor text quality and overscan issues with a previous TV setup.. For over a year now I've been using a 21.5" LG Flatron +(Mini-DVI to DVI)+ with my 17" 4,1 and it's a sweet setup. It really only took a little profile work, mostly on the 17" to get them near perfect. I use the LG as my main display for browsing, movies, photo editing and use the 17" for Finder windows, iTunes, Preference panels, etc.

  • My mid-2010 10.8.2 iMac won't detect external displays.

    My mid-2010 10.8.2 iMac won't detect external displays. I've tried using a third-party minidisplay port to DVI adapter, as well as an Apple-brand minidisplay port to VGA adapter. The monitor I'm using is a Dell SP2008WFPt. It is a functional monitor. I've tried resetting the PRAM, repairing my disk permissions, rebooting, and doing all sorts of wacky stuff with the order I plug things in. Is there a solution? It seems like lots of folks are having the same problem.
    Thanks! This is really starting to make me angry.

    If 10.7.0 or later...
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    If that doesn't help Reinstall the OS.

  • Intel iMac won't recognize external display with Dynex mini-DVI adapter

    I've got an original Intel iMac with a Mini-DVI connection on the back. I'm attempting to hook it up to an external display (a plasma screen, in fact). I picked up a Dynex Mini DVI to Video Adapter DX-AP100 for Apple. This connector has a mini-DVI connector on one end, and both a video-out and an S-video-out on the other.
    When attempting to use the adapter, the iMac does not recognize that there is an external display connected. Here are the facts:
    The external display: I've tried this with a Panasonic Plasma screen connected directly through S-video, as well as a Pioneer receiver (one that switches video) connected both through s-video and composite video. And yes, I've got the settings on the TV correct. I've also tried this with a Polaroid LCD TV connected via S-video and composite video.
    I did notice that when I click "Detect Displays" while the Plasma was connected, the plasma briefly "flashed", implying SOMETHING was happening, but still no dice.
    Anyone have any experience with this Dynex DX-AP100 that could share some wisdom?

    Yeah, I realize S-video is limiting, but I'm trying to keep things as simple as possible. The TV is mounted to the wall and there are not currently any DVI or HDMI cables coming out of it. There's an S-video input from my receiver that I'd prefer to use since it's readily accessible already. In the end my goal is to use Netflix "Watch Now" on the TV, so I'm not too worried about video quality.
    and before someone asks if I considered that the receiver's S-video input might be the problem...I tried taking the s-video wire from the stereo and plugging it directly into the adapter. No dice.
    ONE ADDITIONAL PIECE of information...while trying to get this to work on an LCD monitor, I plugged the composite video connection from the TV into the adapter. Suddenly the Mac recognized an additional monitor, but it saw it as a VGA monitor, not as s-video or composite video, and no signal went to the TV.
    I'm considering trading in this adapter for a mini-DVI to VGA adapter, but that really won't help me with the connection to the TV.

  • IMac G5 see always external display connected

    Hey,
    I watch movies on my TV with my iMac G5 (i use the mini-VGA adapter).
    When i don't use the adapter, the iMac just see the internal display (called iMac), but now it always see an external VGA display.
    I tried resetting PRAM, NVRAM, SMU, but no change.
    I have installed Mac OS on an external hard-drive to see if it was a config problem, but it's always the same.
    That's a problem cause it uses the half memory of my graphic card.
    Perhaps the graphic card has a problem ?
    I don't know what to do.
    Thanks for your help.

    Make sure that the PRAM battery is under 4 years old.
    Then zap the PRAM.

  • IMac G5 iSight detects external display when none is connected

    Hi,
    I purchased an old 17" iMac G5 iSight,in which the screen sometimes suddenly turns to blue and the resolution drops as it detects a VGA display even though no external display is connected. It even shown two displays in the preference panel.
    I opened the iMac and checked the capacitors which look okay. I reinstalled the OS and it didn't fix the problem.
    Do you have some idea where to look? Or does someone know how to disable external displays?
    I found this discussion from another forum: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/172427
    ...but it's ubuntu so I don't understad what they're talking about?

    Make sure that the PRAM battery is under 4 years old.
    Then zap the PRAM.

  • 27 inch iMac (April 2011) - Two external displays - how?

    I've just got a new 27" iMac and have connected two external displays via the mini display port. I can only get one to work, what am I doing wrong?

    Sorry that was a dumb typo on my behalf. Here is the setup:
    Apple 27inch iMac only bought today, so it's the newest version with the two Thunderbolt ports.
    Two seperate external monitors each connected to a seperate port via a DVI cable and Mini DisplayPort to DVI adapter.
    So that's:
    iMac x 1.
    Thunderbolt port x 2.
    External Monitor x 2.
    Mini DisplayPort Adapter x 2.
    3 displays in total. But when I turn on both displays only one will show up.

  • 2013 iMac 27" and 2 external displays

    Hi Guys,
    So my setup is a 2013 iMac 27" with a 27" Thunderbolt Display on one side and an 27" Cinema Display on the other...
    The question I have is...
    Can i configure my audio so basically both speakers on one external display + one of the internal ones become the Left channel and then both speakers from the other display + one from the internal speakers become the right channel
    Its a bit hard to explain so i've made a diagram to illustrate:
    [IMG]http://i256.photobucket.com/albums/hh187/PharaohSam/Speakersetup_zps94899a5c.jpg[/IMG]
    So I want Speakers 1, 3 and 4 to act as the left channel and Speakers 2, 5 and 6 to act as the right channel...
    I've done a bit of reading and Googling and OSX's "Audio Midi Setup utility" (used to create an Aggregate Audio Device) seems to show some promise but I can't figure out how to configure multiple speakers to one "channel" so to speak?
    Maybe I need a third party app?
    thanks in advance guys

    I would love to know the same.
    Ideally I would like to have the speakers on the left monitor for left sound and the speakers on the right display to act as the right with the main iMac speakers doing noting?

  • 2009 iMac 21" as an external display

    I have a 21" iMac (the late 2009 model, 3.06GHz core duo, running 10.6.8) that I'd like to use as an external display for a MacBook Pro 15" Retina (running 10.8.2). I purchased a Monoprice Mini DisplayPort to Mini DisplayPort cable and connected the computers via one of the Thunderbolt Ports on the MacBook and the Mini DisplayPort on the back of the iMac. Pressing Command-F2 on the iMac doesn't appear to work, though.
    I found several references to the 27" iMac, including this KB: http://support.apple.com/kb/HT3924 ... but no specific mentions of the 21" iMac. In theory, it should be the same bi-directional port on both iMac models. So either it isn't and it will never work, or the $10 cable is sub-par. Has anyone connected the 21" iMac as an external monitor successfully?

    Thanks! Guess I'm stuck with a cheap DisplayPort cable I'll give ScreenRecycler a look. Hopefully, it's reasonably fast over wired Ethernet.

  • New white macbook, no external display option !

    I recently got my white macbook replaced with a new one. My old white macbook was great, once i pluged in my mini-vga adaptor to my macbook i hooked it up to my tv, when into display settings and set it appropriatly. Now i got a new white macbook. I plug my mini vga adaptor in, put it to the AV channel on my tv and nothing. And when i go into my macbooks display settings theres no arrangment feature! theres nothing for external displays at all ! Whats happened?!

    I downloaded that - when i click on This Mac it simply says "This Mac Model Can Not Be Found, Please Check You Have The Most Up To Date Version Of Mactracker". Then when i search for updates it says i have the most up to date version. Bahumbug! Useless!
    I've not been having a good relationship with technology lately at all! Obviously my adaptor is now useless, and unless I have a plasma/LCD TV or a new computer monitor, I'll have to deal with not having any ability to hook this up to my television. That was a feature I used on a regular basis.
    Im getting more and more frustrated - I had the opportunity to buy the new Aluminum macbook but it didn't even have a firewire connection which i rely on for my home studio, so i settled for this lesser spec'd white macbook which now also can't do the TV-out function i used regularly. Brilliant.

  • How well does 24" iMac drive a 1920x1200 external display?

    For various reasons that I shall not expound upon, I'm thinking about selling my Mac Pro and replacing it with a 24" iMac. The catch is that I'll need a second 24" display (1920x1200), and I want to be sure that the iMac can drive it without any problems.
    Does anyone here drive an external 24" (or 23") 1920x1200 display with their iMac? If so, how is the video performance? Is Expose and video playback smooth on both monitors? Do you sense any decreased performance on your iMac due to driving two high-resolution displays?
    Thanks for your input.

    i have my imac dual core connected to a sony bravia 40w2000 and it's stunning
    so good , that the next mac i get will be a mac pro and use the bravia as my screen

  • How can I use my iMac (2007) as an external display to my MacBook Pro (2013) while in bootcamp?

    I have an old 2007 iMac laying around that is too slow for use as a second computer, however I could greatly benefit from a second monitor for what I'm doing on my 2013 MacBook Pro while in bootcamp's windows mode (Photoshop, Illustrator, Rhinoceros, etc.). A hardware solution would be ideal, however I am aware that this might not work for an iMac older than 2009. I would appreciate any software suggestions for allowing the use of my 2007 iMac as a second monitor for my 2013 MacBook Pro while on the windows side via bootcamp.
    Thanks,

  • How to lower the brightness of my iMac, when used as external display for my MacBook Pro?

    The keyboard brightness controlls of the iMac do not work. The keyboard brightness controlls of the MacBook only controll the MacBook. Same goes for the display set up of the MacBook, I can change the MacBooks brightness there but not the one of the secondary screen.
    I am working in a pretty dark room and that iMac 27 is at full bightness. Gives me a headache. Please help.

  • External display options?

    I have a 14" iBook G4 and I would like to get a widescreen display to connect to it for watching DVD's and Quicktime movies. I don't have a TV (and don't plan to get one) and I'm getting really tired of watching widescreen movies letterboxed on my small 14" screen!
    I don't know anything about displays or if this is even doable or practical, so I'm looking for advice and suggestions. Any help will be appreciated!

    It works perfectly, check this post/
    http://discussions.apple.com/thread.jspa?threadID=949895&tstart=0
    but you might need to buy a video adapter, it will depend on which computer you have.
    You will be able to have two screens with the same image on the two or two different screens, having your mouse going left to right from a screen to another.
    just perfect.

  • Imac - external display stopped working

    Hi All,
    My imac has developed a problem overnight. I usually have the imac connected to an external display via the mini-DVI connection and everything worked fine. (to DVI --> HDMI --> Pioneer Plasma).
    However today the imac could not be awoken from sleep. Restarting gets to the desktop screen but then goes gray screen. After much troubleshooting, I have isolated the problem to the mini DVI port. The computer will not complete booting up if the mini dvi port is connected. Just in case it was a problem with the mini-dvi to dvi adaptor, I tested it with a mini dvi to vga adaptor. Exactly the same problem with the booting sequence (gray screen as it gets to the desktop image stage). Without the mini DVI port in use, the imac boots up fine.
    Could somebody please give me some suggestions re any further troubleshooting procedures I could try to fix the problem, or does it sound like a videocard hardware problem? Thanks for any thoughts.

  • Windows 7 Bootcamp and Thunderbolt to VGA Adapters for External Displays MacBook Pro i5?

    Is it possible to connect an external moniter to a MacBook Pro using a Thunderbolt to VGA adapter in Windows 7 (professional)? I have tried and tried, when booting, both moniters (both laptop and external) show the "Starting Windows" page, but the external blacks out on the user selection screen. That gives me hope... is there a driver out there that will let me use the external display in Windows 7?
    MacBook Pro
    i5, 4gig, 750gig.
    Windows 7 Pro
    Mac OSX Lion
    LG Flatron Wide
    DisplayPort to VGA adapter (not apple brand, purchased on eBay).
    Thanks.

    You shouldn't require a driver.  I would try booting as usual, then plugging in your external display.  In windows, you can hit "command-P" to toggle between your external display options (mirror, extend, etc.).  Once you do that, you should see the new display show up.
