Using LCD HDTV as a display Buyer Beware!

DO NOT BUY A SAMSUNG TO USE WITH A MAC
I just purchased a G5 and wanted a screen larger (an less espensive) than what they sell at the apple store. I bought a 23" high def at Best Buy at the suggestion of the sales guy. The HDMI output to the PC does not work. There is a 1" border around the edge of the display where your pointer gets "lost" ( you cannot see the top and only a portion of the bottom bar) I went to return the monitor and Best Buy informed me that they would charge a restocking fee which I feel is very unfair as they were the ones that suggested the monitor. I highly recommend that you take your mac to your retailer (and I would stongly advise aginst Best Buy) to test the display before you purchase.
Good luck all!

Composite Video (the yellow RCA-style jack) has NO provision for Audio. It is used in conjunction with Stereo Audio, generally supplied on two additional RCA jacks, Red for Right and White for left.
There are a number of non-interchangeable schemes that combine composite Video and Right and left Audio onto a multi-jack. The issue is which ring the Ground (for everything) is on -- that cannot be re-arranged easily. Your SONY TV may be using one of these:

Clamshell iBooks use yet another different non-compatible pin assignment that puts the ground on 4, Video on 3, R_Audio on 2 and L_Audio on 1. That cable is often still available from Apple retail stores.
Sometimes you can get those signals to "play through" another device in your collection, such as a VCR that has the correct jacks.

  • MacBook Pro using an HDTV as External Display

    I come to you again with another quandary im sure youll be able to help me with. I have a MacBook Pro 15'. a few years old. Recently bought a 42" LCD HDTV and hooked it up using it as an extra display. Video works perfectly for what im using it for, an extra BIG display. however, the audio is still coming from my MacBook. Is there a way to make the audio come from my LG TV speakers and not my MBP. Thanks for your help

    Yes you need a lead from the small phono headphone out socket into the HDTV - depends what Inputs it has to determine the exact cable needed - possibly 2 phono jacks ? possibly a TosLink (Digital Audio) cable ?

  • Using LCD Tv as main display

    I am running my macbook in lid closed mode and have it connected to a 22" LCD tv via a VGA cable, I am using the maximum resolution (1680x1050) and the display is very clear and sharp but is offset to the left. There is a 1" black strip down the right hand side of the display and the far left side is not visible. I have used the horizontal positioning setting on the tv but it does not let me move the image enough. I was wondering if there is anyway to get around this so that my screen is central on the tv ?
    Thanks

    Inverting the polarity of horizontal sync might work, but that requires a program like SwtichResX.

  • How can I use WiFi to mirror my Display on my TV?

    Sometimes I would like to use my HDTV as a display to mirror what is on my desktop's or laptops screen's, running 10.6.8. I can do this wired without problems either using an HDMI or VGA input. But it's not convenient
    Is their anyway to do this with WiFI/Airport? It would seem one would only need a WiFi receiver and conversion hardware on the TV.
    I don't want to just stream media, like with Apple TV, but want to mirror what ever is happing on my computer screen.
    ALL suggestions are appreciated
    TIA,
    Bill

    No.
    iCloud and PhotoStream merely "push" you iOS photos to your other devices.

  • Using MBP with LCD HDTV

    So I've been looking at getting a new LCD HDTV. Someone said that I needed to get a minimum of a 42'' and also at least 1080p resolution. I was going to hook this all up using the HDMI out into a DVI in the TV.
    Is this true? What are your set ups? I'm pretty anxious. I want to use this for movies but also possibly as an external monitor (I know a little ridiculous, but not all the time). Let me know guys! Thanks.

    It is easier than you think. First, get a TV with at least 2 HDMI ports. You may wish to connect the other to a HDTV DVR (cable or satellite) or even an HD-DVD/BluRay player.
    Next, measure the distance. This is critical. 1080p has TWICE as much bandwidth used as a 1080i signal.
    Now, open a new tab in your browser (Apple+T) and go to my favorite cable guys www.bluejeanscable.com I say they are my favorite as they were courteous and honest. Alan Denke, the proprietor of the business, answered truthfully when I asked if his cheapest line of DVI-HDMI cables, the Tartan series, would make it at 50 feet. He asked what kind of hardware I was connecting. I told him, "Well, a brand new 47-inch Vizio with 1080p native support, and a 2.4GHz MacBook Pro." It was then that he said the display didn't really matter, but the source did. And he said the MBP would work just fine.
    Cable arrived here from Oregon in one business day, though I didn't pay anything extra for it. Just plain old Priority Mail.
    It was then I learned I needed about 30 feet, rather than 50. Remember the step up there where it says ,"Measure?" Yeah, I guesstimated. I kept the cable though, thinking that some day I might use the computer in the kitchen or something.
    Now, you'll need to get appropriate playback software. Quicktime just doesn't do .ts (transport stream) files, nor does it do .mkv (Matroska Video Codek) files. It ought to, but it won't. So, no Front Row for HD playback at 1080i. There is hope on the Open Source horizon, though. Go off and open another tab to direct yourself to www.videolan.org
    The latest release even has support for the Apple Remote!
    Getting audio to your setup is a slightly different thing, but can be done with parts from (ugh) radio shag. For analog audio (which is fine for me as my system don't do any better with digital input), just get a 1/8" STEREO (will have 3 conductors [or two 'rings']) to dual RCA out. They usually have 3 and 6 foot versions of this cable. To extend, you've got 3 options: 8', 16' or 20' male to female 1/8" stereo.
    Hope this info helped. If you haven't bought your lcd tv yet, take a look at Vizio. I believe them to be the best bang for the buck out there.

  • Using LCD TV as Display

    I have a 12-inch iBook G4, and I wanted to use my LCD screen as my display. I bought a Apple Mini-DVI to Video Adapter, when I connected it up the picture looked grainy. It looks like it wasn't scaled up just blown up (if you understand that). I can understand this because the computer isn't really sending a digital signal, just a video output signal (i don't think that makes any sense either). Is there any adapter that will make it look just as good as on my computer, or a setting i can change. Thanks in advance!

    The problem is the way the iBooks are designed to output a secondary video signal. In most computers, attaching a secondary monitor gives you the option to either mirror your first display (ie, a copy) or extend your desktop (giving you twice the space for, say, icons).
    iBooks, on the other hand, only have the ability to mirror. The ability to extend your desktop to the external monitor has been disabled in the firmware. This means that your iBook, essentially, sends the *exact same* video signal to both screens. What you see on your laptop screen is what you get on the LCD. Including resolution.
    If I recall correctly, you can scale that image down, but not up. The grainy image your describing is the signal being, as you said, blown up by the monitor itself.
    Unfortunately, there's nothing you can do about this. There are ways of hacking this problem, but none of them are supported by Apple.

  • I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV?

    I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV? I have a MiniDisplay Port to VGA adapter, but there are two issues with it: The new display doesn't have a VGA port, and even if it did, I wouldn't want to have my mac constantly attached to the display by a cable. I was looking for a way to use the TV as a display without any wires. Is there some type of bluetooth setup I could use? Please let me know if you have any suggestions.

    As I wrote above, I think you should look into the Apple TV yourself. The best place to find information about what it can and can't do and to ask your own specific questions is probably in the Apple TV forum, here:

  • Using Samsung LCD HDTV as a monitor

    My TV tells me 'format not supported' when I plug in my 14 ibook g4 using the VGA connection. The TV is an '06 Samsung 32" LCD HDTV flat screen. Anyone have any advice?

    Is there a difference in video cards for pc's and mac's?
    Just about every PC or Mac has different video capabilities so the answer would be yes in almost every situation.

  • Mini DVI to VGA issues w/ LCD HDTV

    I have looked all over and I can't find a solution.
    I recently purchased an LCD HDTV, Insignia Brand which is a Best Buy Brand, and I bought a DVI cable to hook up to my Powerbook G4 using the Mini DVI to VGA cable. When I hook it up to my tv it works, but the screen on my Powerbook looks magnified as does the LCD TV. When I launch Safari or any other program it doesn't fit on my screen or the LCD TV and I have to resize it.
    After I look at displays in system prefernces it says my max resolution is 1024 x 768.
    Any help would be appreciated.
    Jeremy

    Just guessing - the TV's "VGA" input is limited to 1024x768, which is possible although some "VGA" inputs will work higher. Do the instructions mention a limitation like this?
    I think if you turn off mirroring on the Powerbook, at least the Powerbook screen will have normal resolution, and the TV 1024x768. The TV apparently scales up image to fill the screen unless using HDMI, where is leaves the extra 342 pixels blank on the sides (1366-1024). Perhaps the TV has a mode for adjusting how the TV handles lesser resolutions (stretch, dot-by-dot, etc)

  • Connecting a Mac Pro to an LCD HDTV

    It seems that LCD monitors don't come as big as LCD TV's, and I want to use my Mac Pro to watch movies and gaming. A Samsung 35T (30") costs around 1200$ where a 46" lcd HDTV costs about the same price. There is a card you can buy for the Mac Pro which allows you to connect a TV to it through HDMI for the best quality possible: http://www.decklink.com/products/intensity/ (yeah $250 bucks)
    What's my best option for an LCD around the $1000-$1500 range that is good for normal day use, gaming and watching movies. Thanks in advance for any suggestions, advice.

    Since I can't afford to go out and buy several TVs to try them out is there a list somewhere that can confirm what large screen LCDs (40-50-60") do work with the Mac Pro?
    Take your MacBook, a Mini-DVI to DVI adapter
    <http://store.apple.com/us/product/M9321G/B?fnode=MTY1NDA5OQ&mco=MTI1Njk>
    a DVI to HDMI cable
    <http://store.apple.com/us/product/TR842LL/A?fnode=MTY1NDA3Ng&mco=MTUwODQxMw>
    and a DVI-D (M) to DVD-D (M) cable to the TV store and try various sets. If they won't let you try them, go to another store.
    Find a DVI or HDMI port on the TV that supports 1080p and connect it to the MacBook.
    In the "Arrangement" tab of "Displays" system preference, turn off Mirroring. Set the resolution of the external display to 1920 x 1080 non-interlaced. Make sure there is no overscan (the pointer should not go off the edges of the screen). In the "Arrangement" tab of "Displays" system preference, drag the picture of the menu bar (aim carefully, so you get just the menu bar, not the whole display) to the picture of the external display. Make sure the entire menu bar and dock show on the TV.
    If a TV works well on the MacBook's DVI port, it will work with a Mac Pro.

  • Connecting MBP with VGA to 32" LCD HDTV?

    What's up everyone,
    I'm looking at buying the new 15" Macbook Pro and connecting it to my Westinghouse 32" LCD HDTV. My TV does NOT have DVI input, but does have VGA and HDMI. Has the issue with connecting these bad boys been resolved yet? Has anyone successfully connected a Westinghouse HDTV to a MBP using VGA or HDMI? Please let me know, as I don't want to waste money on the new MBP if it isn't able to connect with my large external display (without problems).
    Thanks,
    Zac

    Hi. I wanted your help on choosing the best settings for my external display. I currently have it out to HDMI on my 37" LCD Toshiba.
    I tried to display without "mirroring" but if i dont the display on my tv is too large - very simlar to a zoomed in look. When i mirror the screen i can not see the top bar.
    Video looks great on the screen.
    I want my tv to display similar to a computer monitor!
    Many thanks,

  • Minidisplay Port with HDMI to LCD HDTV

    Hi,
    I am trying to set up my Macbook so I can use my LCD HDTV as a monitor while I am sitting on my couch and to run iTunes, etc.
    I can get everything to appear on the TV via the Minidisplay port HDMI connector, but the problem is that all the fonts, especially those in the browser are very small and hard to read from the couch.
    I have a 52 inch LCD TV and sit about 12 feet from it, I would think there must be a way or a setting to change to make things on the TV bigger, but I cannot figure it out.
    Anyone have any ideas?
    Thanks,
    Ben

    So is the TV being run at 1920 x 1080? Are there other options in Displays Preferences, like either 1366 x 768, or 1280 x 720? If so, have you tried those settings? That should enlarge things.

  • Are there any LCD HDTVs with built-in bluetooth?

    So I'm going to buy an LCD HDTV and I'd like to be able to use it occasionally as an external monitor for my iBook G4. Does anyone know of a brand that makes LCDs with built-in bluetooth? I could only find two--a Samsung that has been discontinued, and an LG that is only available in Europe.
    If not, are there any ways to use my to-be-purchased tv as a wireless computer monitor?
    Thanks.
    -EM

    Having an LCD TV with Bluetooth wouldn't help you to use it as a wireless monitor at all. Bluetooth is nowhere near fast enough to transfer real-time video data, let alone a high-resolution or HD computer display.
    Bluetooth is for transferring small amounts of data. It would take 10-20 seconds to transfer 1 single medium sized JPEG image for example.
    Wireless HD is a new technology that hasn't really made it to market yet as the standard is still being worked upon and adopted by manufacturers:

    Why does it need to be wireless? If you're close enough to be able to see the TV at a usable distance, you're close enough to simply connect a cable.

  • Bad Picture Quality On SD Channels With HDMI And Panasonic VIERA 720p LCD HDTV

    I just bought a new Panasonic VIERA 32" 16:9 8ms 720p LCD HDTV TC-L32X1 for my in-laws when they finally had Verizon FIOS brought into their neighborhood last month.
    Install was by the Verizon tech using the HDMI cable I also had shipped to them.
    The HD channels quality is excellent, but the SD quality is smeared -- almost looks like an impressionist painting.
    It is not the TV -- the TV menus are crystal clear, as are the HD channels.
    And, it is not just the broadcast HD -- the DVR box menus are also smeared when viewing as SD channel, as is the guide and the pop up channel info.
    We've tried all the settings on the TV -- Zoom, 4:3, etc.
    The other TV (an older CRT) actually has better SD quality than the Panasonic.
    My research indicates we're not the only ones on FIOS with this problem. Someone suggested using the component hookup rather than HDMI?
    Other say that IMG 1.7 is supposed to solve the problem, that the SD quality was fine before IMG 1.6.
    Any suggestions, solutions, or updates?
    The picture is virtually unwatchable.
    Thank you!

    Joe01880 - Being a new customer as of last October, I have never seen anything other than IMG 1.6.  My understanding from other posts is that before IMG 1.6, the SD PQ on an HD box was just fine.  I'm not sure what the complaints/gripes/begs were for IMG 1.6 but it seems to me that, if Verizon knows what changes were made, it should be straightforward to determine which changes caused a deterioration of the PQ.  I think it's been at least 6 months since the first complaints of poor PQ, so I don't really see how anyone can claim that Verizon is in danger of "rushing" an update to address this problem.  I also don't think that a forum topic, no matter how much it complains or gripes, will cause Verizon to rush.  I am much more worried that during a large portion of my 2 year contract that the issue won't be addressed at all, so I'm happy to add my voice to those complaining."
