DVI- HDMI discoloration on HDTV (as second monitor)

Hello all.
I have been having some issues when using my Philips CRT 30" 1080i HDTV as a second monitor via a DVI->HDMI cable. There seems to be a discoloration that occurs (my best guess being a "green" discoloration) that occurs in the top left corner of the screen. It is made all the more apparent when you then unplug, and a purple haze is left in the corner of the "blue" video input channel. (i imagine the green discoloration on the blue channel yields purple).
From what I can tell, this problem does not occur on any other video input (say, a Wii on the composite channel, or an XBOX on the component, etc).
I had heard rumblings that it could be, in order of bad to worst: a bad HDMI cable, a bad HDMI input on the television, or the television going bad period.
Wanted to know if any of you have had or heard of similar experiences. Need to decide soon if I'm going to had to just buy a new HDMI cable, or if I need to buy a new television/monitor for a job coming up.
Thanks in advance!

Problems like that are caused by stray magnetism that cause misalignment of the electron beams from landing on the proper phosphor color. The set itself has a demagnetizer, but sometimes the magnetism is too strong for the built-in demagnetizer to overcome. But calling in a TV repair person to do a demagnetization is, I'm afraid, a throw back to bygone days. But that's what your TV needs.

  • HDTV as second monitor?

    Will OS X use an HDTV as a second monitor? I'm thinking of running Mini-DVI from MacBook to a DVI<->HDMI cable, and from there into the HDMI port of the TV. Any reason this wouldn't work?

    Welcome to Apple Discussions:
    It works fine - not only as a second monitor, but optionally as a desktop extension of the computer monitor, doubling the desktop space. The settings are in the display preferences when the HDTV is connected.

  • Second monitor stopped working on upgrade to 10.10

    I recently upgraded my mid 2010 Mac Pro from 10.6.8 to 10.10.1. This upgrade resulted in the loss of signal to my second monitor. The primary monitor connects via an hdmi/vga adaptor and the second monitor uses the video card vga connection. Both monitors worked fine until the upgrade. After the upgrade the main monitor works fine. The second monitor is recognized and appears in the system preferences-Displays as well as the System Report-Graphics/Displays. Looking the other way the computer connection is recognized by the monitor. The second monitor is black screen with a no-signal message. I have checked all connections, reset the prom and tried various connects and dis-connects of the video cables and restarts all with expected results just no picture on display two. I have not yet reset the SMC because I am not familiar with any associated consequences. Any suggestions are appreciated.

    Resetting SMC could solve the problem, though try reverse the connection way(main monitor connect DVI directly and second one via the adapter) could solve the problem.
    What's video card are you using by the way?

  • New 13" Macbook Pro trying to connect to a Panasonic VIERA TC-L42U30 as second monitor. I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. The Macbook does not sense the second monitor (TV). Help?!

    I've been a Mac since 2008, so I know my way around the system pretty well. This issue, however, has me stumped. I had an iMac until now and only now am I experiencing some difficulty with my new MacBook Pro. The model I have is the newest 13" Macbook Pro model and I'm trying to connect a Panasonic VIERA TC-L42U30 42" HDTV as a second monitor via the Thunderbolt port.
    It worked the first two times and hasn't worked since, after 10-15 attempts with different configurations, turning things on n off, restarting the mac, unplugging the cables, adapters, TV, resetting the P RAM, etc... I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. No matter what I do, the Macbook does not sense the TV as a second monitor anymore.
    I took the MacBook Pro to the Apple Store, and their "genius" there had it working fine with a DVI connection to a regular monitor. The Panasonic TV I have has HDMI connections and one VGA connection which does not support HD, but no DVI option. I want an HD connection to mirror or extend my MacBook Pro screen. At the Apple Store, they didn't have a Thunderbolt/Mini DisplayPort to HDMI adapter, so he could not try that out for me.
    Anyone else have this configuration or another similar one with a Panasonic HDTV?
    Ideas? Suggestions? Anything?! Help!!
    P.S. I'm running Mountain Lion, if that wasn't already obvious. Everything is up to date in my App Store as well.
    Thanks!

    Hi There,
    I have had the exact same issue but with a projector.
    The issue lies with Mountian Lion 10.8.2.
    I tried many a combination with no luck to get HDMI working.
    Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
    Bought my macbook home and voila, now displaying through my projector.
    There is a small graphics update after 10.8.1 which seems to be the cause.
    Hope this helps.
    Thanks.

  • Best way to add second monitor with HDMI input

    I have a 24-inch Mid 2007 iMac.  Processor  2.4 GHz Intel Core 2 Duo  Memory  4 GB 667 MHz DDR2 SDRAM  Graphics  ATI Radeon HD 2600 Pro 256 MB.  I need to add a second monitor, and while I'm at it, this new monitor will be an HDTV Monitor with an HDMI input.  My iMac has the original USB connections.  So I'm thinking an ethernet to HDMI adapter should do the trick.
    Is this right?  If so, what supplier makes a good ethernet to HDMI adapter?

    Hi
    I've always thought powered DVI (ADC) was introduced on the Gigabit Ethernet G4s, like your dual 500. It should be easy to check, as the graphics card has an extra power 'stub' which fits into an extra slot on the logic board, between the main AGP slot and the back of the computer. If all the gold connectors on the Radeon 9000 are seated, I think you must have powered DVI/ADC. If some are 'floating' above the logic board, you haven't.

  • How do i connect my hp 610-1130a to my tv as a second monitor. i only have hdmi inputs on my compute

    How do I connect my computer to my TV as a second moniter. I have a HP 610-1130a touch screen running windows 7.
    It has 2 HDMI in ports.

    Here are the specs for your HP TouchSmart 610-1130a Desktop Computer. You are correct in stating that it has 2 HDMI inputs... these inputs are used for connecting devices like XBox, PS3, DVD payer, Blu-Ray player, etc., so that you can watch/play them on your computer screen. Your computer, in fact, doesn't have a video output of any kind (VGA, DVI, HDMI, DisplayPort, etc.). You will need to purchase a USB-to-video adapter such as the EVGA UV Plus+ UV39 to use your TV as a monitor.
    Please note that if you wish to "extend" your Windows "desktop" to your TV, you will need to disable the touchscreen as issues controlling the cursor will occur. If you wish to "copy" or "duplicate" the image on your computer to the TV, the touchscreen should function as normal.

  • Bootcamp mini-DVI second monitor compatibility?

    Hi, I am planning to buying an iMac 20-inch, 2.4GHz (Intel). I want to attach another 20-inch monitor via the mini-DVI port. This should be no problem as long as I stay in Max OSX (Leopard).
    BUT my question for help is if I (need to) boot up in Windows, can I access both monitors through the mini-DVI out-port and Bootcamp? Has anyone tried? I want to run Windows and use both monitors... Any limits to what I can do? (resolution and such)
    Thanks, hope you understand my question...
    /P

    BUMP! I'm having an issue with this also. Just installed bootcamp 2.1 with XP SP3 and I can't get anything to display on my second monitor (Mini-DVI to HDMI). It just stays blank.
    Windows recognizes it in display settings but no matter what I do it stays blank. Kind of a bummer for not being able to watch the Celtics playoffs streaming...
    Anyways.. any help would be appreciated.

  • How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.

    How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.
    the computer:Mac Pro, Mac OS X (10.9.5), 2 x 2.66 Ghz 6-Core intel Xeon
    the TV: LG Smart tv

    The Mac uses a highly-parameterized universal Driver for every display. The parameters are set at certain times when a query is sent to your display. The display MUST answer with its name and capabilities, or the screen stays dark. A TV set that is off or "not paying attention" because it is set to a different port when the query occurs will rarely answer, and so will often remain dark.
    You can use tools in the System Report to see whether your display has been detected at all. If it has, the report will look something like this, but its name will appear:
    The times when the query is sent are:
    • at Startup
    • at wake from sleep
    • when the Mac-end of the cable is inserted
    • when using the Option ( Detect Displays ) button in displays preferences

  • I've just hooked my 20" iMac up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and works well, EXCEPT for the green tinge (or hue) that is showing up on my TV. Any suggestions or ideas?

    I've just hooked my 20" iMac display up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and everything works well, EXCEPT for the green tinge (or hue) that is showing up. Everything else looks pretty good though..... The color that is on my iMac is still good, Its just green on the TV.
    Anyone have suggestions or ideas?

    Try opening the Display System Preferences, then click on the Color options in the Display preferences window that appeared on the Toshiba display. Click on the Calibrate button and follow the instructions for creating a custom ColorSync profile that will hopefully solve the green tinge issue. The Apple Display Calibrator Assistant software that launches when you click on the calibrate button will walk you through the process.Assuming that the green tinge is minor and that you don't have a more serious cable or hardware issue, I am hopeful the results will be worth it.

  • Is anyone else experiencing problems with the thunderbolt port on their Mac Mini's regarding using it to connect a second monitor? I've got the Mini Display Port to DVI-D adapter along with a DVI-D cable and I can't get an image on the second monitor.

    I had an dual display image / setup working twice for a few seconds, but then it cut out. I think there may be a problem with the thunderbolt port.

    As far as I can tell you have only listed that you have a DVI monitor connected to the Mini Displayport socket (i.e. the Thunderbolt socket) via presumably the Apple Mini Displayport to DVI adapter and a DVI to DVI cable.
    You don't appear to have listed what the second monitor is and how it is connected (even though not working). As such I cannot tell what may be wrong.

  • DVI-HDMI Adapter for hooking up a HDTV...Few problems...

    I have a spare 32" Sharp HDTV with HDMI, so I placed this next to my Mac Pro and used a DVI-HDMI adapter. Here are the problems:
    With my standard GeForce 7300 GT you cannot use both connectors, as they are too close together - so I could not even test to see whether both DVI outputs can work at the same time. So I have to disconnect my 23" cinema display. Now, the Macpro recognizes the TV - in the display preferences - but the resolutions are not good - the only one that works is 1280x720. Other resolutions listed, ie, 1344x756 and higher are listed as interlaced and all cause flicker. This means I do not see the OSX top menus.
    I wish to be able to show clients samples of edited movie clips on a HDTV both in FCP and standalone QT. I doubt that appleTV is the answer, as this only works in iTunes - plus, my Mac is next to my TV anyway.
    Any thoughts on making this work better? I am trying to not have to buy a new video card. Maybe the Black Magic Intensity card for HDMI output is the answer?

    I can live with the lower resolution - the TV is actually 1366 x 768, but the most annoying is not being able to use both DVD connectors on the card at the same time - they are too close together, how stupid is that?
    Ideally, I would like to see both the cinema display and the HDTV running at the same time - or least not having to manually switch over the adapter at the rear.
    I see no way around this, unless I change video cards but for $250 I can get the Black Magic HDMI card which outputs DV via HDMI to HDMI.

    HP - 23" Touch-Screen TouchSmart All-In-One Computer - 8GB Memory - 2TB Hard Drive ? I used a HDMI to HDMI cable and the monitor was not  recognized.

    Here are the specs for your HP TouchSmart 520-1070 Desktop Computer. As previously stated your computer Doesn't have a HDMI output, instead it has a HDMI input. This is designed to let you connect a game console, a DVD/Bluray player, etc. to use as a monitor.
    If you wish to conect a second monitor to your computer, you will need to use a USB-to-video adapter such as the EVGA UV Plus+ UV39 or EVGA UV Plus+ UV19. Using an adapter like these with the touch feature of your computer may cause issues with pointer control and you may need to disable the touch feature to use "extended desktop".
