Using Polaroid HD-LCD tv as Mini display...NOT! :(

Very similar symptoms as described in the post re: ENVISON wide scieen.
Well, maybe not exactly...tv is 19" Poloroid TLA-01911C w/ oodles of inpiut options like most other brands.
I opened the box attached a VGA cable to the tv, powered up tv and mini.. as mini was starting
I grabbed tv remote, loaded batteries and selected INPUT SELECT and switched to "PC"
as the input source. The screen showed the status: 1440 x 900 , PC but screen remained drk blue.
So I swtiched the tv off and on again and viola! -- my mini 's desltop. appeared.....oppps waiti...where didi it go?
Blue screen again .....status :NOT SUPPORT.
So I rebooted the tv then the mini.. and I watched the mini grey screen w/ apple logo then saw it switch over
to the display with my deskiop..... cool. I'll note here that the mage was as perfect and in proper size
proportion as my regular 20"LG LCD monitor.
Twenty maybe thirty minutes later I noticed the blue screen had reappeared with NOT SUPPORT status.
Perhaps the miinii went to sleep ? So i clilced and fiddled with the keyboard.. blue screen remained.
Rebooted minii and the tv switched ovee to show system starting up by immediately swirched back to blue NOT SUPORT when mini desktop is displsyed and this is what it does everytime.
I quiclly had the same idea as mentioned in the other post re:ENVISON..But the 1440x 900 size
absolutely the one that matches the tv and no oher size selcted will even display the start up screen.
Cable problems,you suspect? Perhaps....lets find out.
Okay lets try using two new VGA cables ... first cable :NOT SUPPORT...second cable : NOT SUPPORT
Perhaps an aversion to VGA cables ... so now lets use DVI cable into VGA male adsptor.. .NOT SUPPORT
Picky huh..okay Lets go DVI female adoptor to component video RGB cables... NOT SUPPORT
Okay okay lets get serious about this now and go DVI female adaptor to HD cable...NOT SUPPORT
Yes,btw.I changed inpuit selctions for those last two as the VGA/PC was not used.
So that was $200 in trial/error cables/adaptors that Ill need to return to the store.
At this point, unless there is a known documented cause /effect understanding of any mini-related
issues or limitations which attribute to this problem, fixable or not, I must assume its a Polaroidal-related
malfunction.
Suggestions, insights?
Thank you!
Scott

in case you haven't fixed this problem...it happened to me today and i found another post that totally fixed it!!!
Boot in safe mode!!!!!!
here is what helped:
"boot into safe ode (hold the shift key down when starting up) and once the system is running [note: holding the shift key down for a couple of minutes...seems like its not going to boot up - but it will - just be patient] - once booted up go into system preferences...go to display pick resolution 1024x768 {note: this is what my polaroid tv's computer display max resolution per owners manual for tv] - ensure the correct refresh rate is selected...[mine was 75 hz] and the reboot computer - should work fine!!!
good luck!

  • Mini-display not recognizing any LCD

    I have an IMac 27-inch OS 10.6.7 Intel-based.  I cannot get the Mini-Display port to recognize any LCD screen.  I have two adapters.  One for VGA and the other for DVI.  I have tried two different monitors with the same results. Neither VGA nor DVI will see the monitor (which displays the "no signal found".  Both monitors work on a PC laptop.
    Any help be appreciated.

    Morning kirstenpolley,
    Thanks for using Apple Support Communities.
    If you know the hdmi cable is good.
    You may want to try a different input channel or a different display adapter.
    For more information on this, take a look at this article:

  • DVI to Mini Display not working

    hi,
    i just bought an adapter to go from my DVI 24" VG2030 monitor into my macbook pro's minidisplay port.
    i've got everything connected and powered but nothing happens with the display. "detect display" seems to do nothing when i click it and merely restarting the computer doesn't yield detection of the monitor.
    i called tech support and established that the monitor is fine. the only thing they said was that it could be the adapter (because i couldn't test it on another computer... i don't know anyone else with a minidisplay port).
    is this a bug with 10.5.5 as i have read about many people with this problem ?
    if so, is a software update coming soon ? i'm a Visual Effects major at SCAD and have a film to edit and some Houdini work to do, and this 15" screen is killing me.

    I've got a similar situation. Mini DisplayPort -> VGA adapter works fine. DisplayPort -> DVI fails to see ViewSonic monitor completely.
    On the assumption that it was a fault with the adapter, Apple sent a replacement mini displayport to DVI adapter -- which also fails.
    The monitor and monitor's DVI cable work fine with an older PowerBook 17 using the previous generation of adapter.
    The monitor clearly sees no input on the DVI cable, and the monitor does not show up in the displays system pref pane regardless of how many times you "detect displays".

  • Disable my MB display while using an extenal LCD?

    Hi, when i have a dual display on my macbook, and i close the display on the macbook, the computer goes to sleep, autimatically,
    yeah, that's normal.
    now, if i click on the BT mighty mouse, the computer wakes up, and since the internal display is closed, my MB goes into a single display mode on the external display.
    so i am wondering if its possible to toggle that single external display without going to sleep, because i beleave it wont be a good thing for my mb.?
    thanks!!

    you can open the lid
    after the external screen comes on and the internal
    screen will stay off.
    exactly, that's the final result i want have, use only my lcd while the internal display is off(lid stays open). but i wish i could do that without going to sleep and then wake it up.
    i thought if i put MB to sleep then wake it to quickly, it will eventually break the HD.

  • Mini display port to DVI not working

    The mini display port of my late 2009 27" iMac is not working with DVI.  Using the same monitor, DVI cable, and mini display to DVI adapter, I can connect my Air with no problems.  So the monitor, adapter, and cable are fine.  I can also connect my iMac to the same monitor using a VGA cable and a mini display to VGA adapter.  So the problem clearly seems to be with my iMac.  Has anyone had similar problems?  Any advice?  I think the image quality of DVI is substantially better than VGA so I really would like to get this working.  But I don't think the difference is worth carrying my 27" monster into the Apple Store. I could buy a mini display to HDMI adapter, but I would rather not buy yet another adapter (I think I have about 15 already with my various idevices) - and it might not work either. The DVI setup is simple and really should be working.  I bought a monitor and also a HD TV with DVI ports specifically for this.  Thanks.

    Hello,
    Using the VGA connector, what resolution is set on the Monitor?
    Is there any input choices on the Monitor for port or source?

  • IMac 24" (early 2009) Mini Display to HDMI possible?

    As there is no Mini Display to HDMI adapter available as of yet I tried to connect a new 24" iMac (early 2009) to a Sharp LCD TV via: Mini Display --> DVI --> HDMI.
    Although the iMac recognizes the Sharp and switches resolution automatically (I also tried every other available resolution) the TV screen stays black (HDMI is EXT 5, but I also tried the other EXTs).
    I googled and it seems to me that our setup works for some people with some LCD TVs (Sharp too).
    Any thoughts where the problem here could be?

    Open System Preferences Displays pane Display tab. If there are two displays being recognized, there should also be an Arrangement tab, but stay on the Display tab.
    Click the button that says +Gather Windows+. Although you cannot see the image on the TV (since you say it is black), you should now get the control window for that TV display on your iMac's display.
    Try making adjustments to the resolution and refresh rate to see if you can get a response on the TV's screen.

  • MINI DISPLAY to THUNDERBOLT

    Friends,
    I'm using a Mac Pro with a mini display port for display.
    Can i connect to an Apple thunderbolt display from this mac pro?

    Unfortunately not. If you want to use an Apple display, the older non-Thunderbolt versions (mini-display port) will work.

  • Using An ASD LCD display with a new Mac Mini

    I want to utilize a 17" Apple Studio Display with my new Mac Mini.
    Does HDMI support the 35-pin Apple Display Connector (ADC)?
    It would require an adapter with female 35-pin on one side and a male HDMI (DVI) on the other. The Apple DVI to ADC adapter doesn't work with the Mac Mini HDMI port.
    If two adapters are needed they must have the correct gender connections.
    Thanks.

    Your correct, you would need an Apple DVI to ADC adapter, And ether mini display port to DVI OR HDMI to DVI adapter. (just a question of witch port you want to use)
    Apple DVI to ADC adapter when they were first released cost about 120; now they're kind of rare and harder to find. Online they can go for 200 dollars. so 120 to 200 dollars to make your display work; and displays don't last for ever they have parts that will break down. Older displays have a light bulb inside them; witch burn out just like all the other light bulbs in your house.
    Also DVI to ADC adapters can some times give you blurry images and or text.
    For 120 dollars you can buy a generic brand 19" LCD. That 19" LCD would have better contrast ratio, brightness, and refresh rate then the old 17" monitor. (and it would have a warranty) Or for 200 dollars you could buy 23" monitor.

  • Help using a mini display port to HDMI cable with MacBook Air and TV

    Hi, Apple gurus. I need help setting up my MacBook Air to my Vizio TV using a mini display port to HDMI cable that I just purchased on Amazon.
    And here's info about my MacBook Air:
    In the Amazon reviews, someone posted the following how-tos, which aren't working for me:
    1. Plug in both ends, mini display port on your macbook and the HDMI on any available port on your LCD.
    2. Go to upper left Apple menu and scroll down to system preference. Or use your FINDER from the dock, go to applications, then system preference.
    3. Click on Displays
    4. Click on DETECT DISPLAY
    5. A similar screen pops up with name of your LCD, mine says SONY LCD, click on ARRANGEMENT
    6. Click the box that says MIRROR DISPLAYS.
    7. Go back into system preferences and go to SOUNDS which is located under HARDWARE.
    8. Click on OUTPUT, then select HDMI, which should be listed next to your LCD name.
    I ran into trouble at step #4. My MacBook Air doesn't list the option of "detecting display." I do, however, have the box mentioned in step #6, "Show mirroring options in the menu bar when available."
    Regarding step #8, HDMI didn't appear in the list — I only see "internal speakers."
    So, what am I doing wrong? Or, did I buy the wrong cable?
    Thanks in advance for your help!

    Or you need to get an appropriate adaptor. The Griffin adaptor sold on Apple's Online Store will work with a standard HDMI cable.

  • I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

    I've got a MacBook Pro 15' running 10.6.6. I want to use an external monitor for my graphic design work using Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

    In addition to pixel density, you are up against the translation driver card in the TV.
    If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page.  At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
    Mac falls into the top 25% of the page, maxing out at 1366x768 often.  This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
    I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector.  Computer monitor first, TV second.  But the thing is only 27 in.  Good thing TV is not as important to me as it is to others.

  • MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

    MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

    dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
    Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
    I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
    Apple, please help!

  • Crashing when viewing video using Mini Display port

    My 13" MacBook Pro (Model Identifier: MacBookPro7,1) with the NVIDIA GeForce 320M, frequently crashes when using the Mini Displayport. This occurs when using a Mini Display to DVI cable, which is then connected to a DVI to HDMI adaptor and Toshiba rear projection CRT TV with HDMI input. The MacBook Pro always recognizes the TV normally and displays a second display.
    The crash occurs either during video playback but more frequently *when ending playback on the TV*. It frequently crashes with a pink/magenta screen on the MacBook Pro. The freezing is a hard lockup, completely unresponsive and requires me holding the power button down for 5+ seconds to recover. It doesn't matter if it's a DVD playing or video file of some sort.
    The DVI to HDMI adaptor and TV's HDMI port otherwise work flawlessly with other devices, including my previous G4 based laptop with DVI out.

    I have a similar deal. I'm using the MiniPort VGA adapter for a secondary LCD screen and it crashes in the same fashion, sometimes it takes 30 mins, sometimes it takes 8 hours for it to happen. Please let me know if you figure out a solution, i'll do the same.

  • HT201177 How to connect my MBP 13" (Mid-2012) to a projector/LED TV using a mini-display port VGA adapter (CAPDASE)

    Hello Sirs, I'm having a hard time connecting my MBP 13" (mid-2012) to my projector using my mini-display-VGA out adapter. But when I switch to Windows 7 (via bootcamp), it can easily be connected... Please help me with this problem. Thanks

    Try connecting the Minidvi to the VGA and connect it all together, first try turning ing on the MBP, then connecting dvi to the the projector. Make sure your projector input is set for VGA. If noo joy invert the affored mentioned proceedure. You should see your image if not, try going to system preferences>displays, click display.   Try readjusting the resolutions in display. reboot monitor.
