Connecting Mini to HDTV

I've got my Mini connected to a HDTV via a DVI to HDMI cable and it seems I can't get the display size to exactly match my TV's display size. If I enable overscan then a noticeable amount of the screen is cut off on all sides. If I disable it, then the image is too small for the screen.
If I connected via VGA then the image fits pretty closely, but there is still some overscan. Suggestions?

Is your TV a rear projection TV by any chance? RPTVs are, by design, set to overscan the image to some degree and hence are not very good when used as computer monitors. They really don't have a way displaying full screen and native.

Often lose wireless connection when using HDTV as monitor

I have an unusual wireless networking problem when using my Samsung HDTV in my living room as a monitor for my MacBook (when watching Internet TV shows, for example). Frequently when I switch URLs, networking freezes, even though the connection appears strong, with the Airport symbol at the top of my screen showing all bars. To re-establish the wireless connection, I have to go through the process of re-joining my network through the “Join Other Network" option. The signal holds as long as I don’t try to change it, as in selecting another URL.
I connect to my HDTV via HDMI cable, using a mini-DVI to HDMI adapter from my Macbook’s video-out port. The audio connection is a mini-plug from the Mac’s headphone out jack to stereo RCA plugs associated with the TV’s HDMI port.
The wireless connection is through a Lynksys Wireless-G 2.4 Ghz, 54 Mpbs Broadband router.
I’d appreciate any solutions the Apple user community has to offer.

I'd say this has nothing to do with your display. The problem will likely lie in either your router settings, network settings or a simple signal strength issue. Try first changing the broadcast channel on your router, and make sure all settings are correct for your desired network.

Help connecting T60 to HDTV

Hello, I need help to understand what I should do to connect my laptop T60 (1951-bs7) to my Panasonic HDTV (capable to display 1024x768 resolution.
I just purchased a cable from VGA to component video (Y, Pr, Pb) but when I connect it to HDTV I don't get the video shown on TV, I tried all the resolutions (obviously after doing Fn-PF7 to also have the video signal on the VGA output) I can't get things to work other than a few green dotted lines for the lowest resolution.
Are there any drivers I should update on my graphic card to allow component to be managed appropriately through VGA ?
Last but not least, I'm waiting for the T60 advanced dock (I just ordered it), which also has a DVI output: can I expect at least this to work with a connecton DVI-HDMI ?
Thanks in advance for your help
Paolo

you could also try to see if there is an option to configure your laptop for that in Presentation Director.
Ignorance is no excuse!

Help w/ connecting MacBook to HDTV

I want to be able to connect my macbook (black) to my LG HDTV. I am using the DVI adapter to VGA (RGB). All I get is "no signal" on my TV. When I tried it out w/my Dell (didn't need the DVI adapter since my Dell has a VGA input), it worked right away. Anyone know why I would be getting "no signal?"
Thanks -
Jen

I used to have the same problem. I opened up the settings on my laptop while it was connected to my HDTV and under the Display menu I played around with the resolutions. Eventually one of them gave a signal to my HDTV. Hope that works.

HDMI Issue connecting laptop to HDTV

Hi Guys - I had my laptop connected to my HDTV via HDMI. I had unplugged the HDMI to take the laptop on vacation. It's been awhile since I connected it. Now when I connect the HDMI, I am getting the visual but not the audio on the tv. What am I forgetting or do I need to change a setting on the laptop (Toshiba Satellite C855 S5350)?
Thanks!

I believe that you need to go into your audio settings when the laptop is connected to the TV and change the default audio device from the built-in laptop speakers to the entry marked "HD audio" or something similar.
P.S. The cake is a lie.

How do I get rid of "echo" lag on my Airport express when playback when I play music on my MacMini, connected to my HDTV?

I have a MacMini connected to my HDTV; Whenever I am playing music from my MacBook Pro music library (via Homesharing through the TV) and airport express I get a one second delay on the airport speakers. Is there a way to avoid this?

Not unless your sound system has a delay setting. Some do, to compensate for TV (for example) which can be slow at processing sound.

Choosing between 720p and 1080p on Mini connected to Sony HDTV (1920x1080)

I have a late 2009 Mac Mini and a SONY HDTV and had no difficulties at all in hooking them up. I just connected the Mini Display Port to DVI connector which ships with the MAC Mini to a Belkin DVI to HDMI cable (also available from Apple Store) and connected the HDMI to my TV. I switched on the TV, selected the correct HDMI input, then switched on the Mac Mini and could see the picture immediately. I was missing the menu bar at the top so went to SYSTEM PREFERENCES and then DISPLAYS and the OPTIONS tab, and unselected OVERSCAN, and that gave me a perfect picture (slightly smaller than full screen but perfectly adequate as far as I'm concerned).
By default my resoluton was set at 1080p (presumably the Mac detected that the native resolution of my TV is 1080p). The DISPLAYS box shows a number of resolution with a little TV screen icon beside them, as if suggesting those resolutions for use with the Sony. It shows 480i, 480p, 720p, 1080i and 1080p. There are also lots of others without TV icons beside them.
The only problem I found is that 1080p made it quite difficult to read text on my screen, even though it's not very far away from the sofa. My eyesight is very good but I couldn't read the screen comfortably when surfing the net or even when changing settings etc. I swiiched, therefore, to 720p and this produces a very comfortable size of text for using the MAC.
My question is whether it really makes such a big difference whether one chooses 720p or 1080p, as I really can't see much difference for playback of video from Hulu or other streaming websites. Even when I played a DVD movie from the Mac Mini superdrive, the difference in quality was hard to detect. I guess if I tried viewing Full 1080p HD material, there would be some difference, but how much of such material is available on the net anyway? I take it that switching between 720p and 1080p wouldn't cause any harm, if I chose to do so occasionally for watching any Full HD movies that I rip?
Look forward to hearing views!

Hi- I also picked up a mini a week ago, and have it hooked up to my Sony HDTV via HDMI, just as you. The same thing happened the first time I connected the mini to my tv- with overscan on, the top and bottom of the screen were cut off.
The solution is to pick up your Sony remote, go to the onscreen menus, and make sure that 'full pixels' option is selected. When you do, the screen will be absolutely perfectly aligned.
I mention this because while in overscan mode, I find that the Sony makes an absolutely beautiful screen, and text is quite easy to read, albeit a bit small.

Connecting Mini to Phillips 55PP95 0217 HDTV

So I am trying to connect a new Mini to a Phillips rear projection HDTV using a DVI-D duel link cable to the DVI port on the TV. When I first started it up, I could see the grey screen with the apple logo and the TV showed 480p, but as soon as it would go to what would be the screen with the startup status bar on it, the TV would show a bunch of horizontal lines, like it was attempting to send at 720p. My TV can handle either 480p or 1080i but not 720p. After hooking it up to a VGA monitor, going through the initial setup and lowering the resolution on the monitor, it still isnt working.
One final tidbit of info, when the computer was forced to shut down by holding the power in the begining, each startup I could see the grey screen with the apple logo before the image went out. After going through the initialization and connecting to the TV again, the first time I still could see the apple logo, but after shutting down the computer using the keyboard, now even that initial splash screen appears to be sending in 720p.
Starting in Safe mode doesnt help either. Is there any way to force the display settings to either 480p or 1080i without using the monitor? Thanks,
Steve

Unfortunately there is no way to force the mini into a certain video mode short of selecting it in Display Preferences with the display in question attached. Since you can't get a working screen from the Philips, you may need to resort to using a second computer on the same network with the mini and running a VNC server on the mini and a VNC client on the second computer. In this way you will be able to see and control the mini's screen remotely from the second computer. You can then set 1080i (assuming it is an available option in the mini's preferences) and from there on the mini should stay locked to that setting.

Problem trying to connect mini-dp dvi to HDTV

Hi, i just came home all happy from buying a mini displayport to dvi, had all the cables set but it seems its not working... I dont know if i have to do something but as of now can´t see anything in the tv.
I´m using the mini displayport to dvi and a cable that is dvi-d single link to hdmi.
Might the cable be the problem? do i have to press a button in the mac? i´m totally lost here.
Thanks!

I know certain devices require an HDMI connection to work. Part of the implementation of HDMI was to try and curtail pirating by digital copying, so many devices look for a "handshake" in order to function.
I have personally just purchased a new MBP, so I don't have personal experience with what you are trying to do yet, but I did get a Mini Displayport to DVI adapter and we have a DVI to HDMI cable at our church. If I have time I'll try it out to see if it works or not and let you know.
I do know that my Mini Displayport to HDMI adapter I just received this afternoon from monoprice.com DOES work on my Panasonic plasma TV. For $10 it might be worth getting instead of wasting time troubleshooting what you have.

Just connected iMac to HDTV

Hey guys, Just connected my iMac to my samsung HDTV via a mini dvi to HDMI adapter, picture is awesome, i just have a question, i am basically in a DUAL SCREEN mode, both my LCD and my iMac screen work together at the same time, moving my Mouse cursor all the way to the left enters my LCD screen and i can do whatever i want on the LCD screen! its really nice, but i have a question, when i watch a video or something on the LCD TV side , my iMac's screen stays ON, as in the screen doesnt turn off as it should , i have it setup so the screen turns off after 3 mins of inactivity but heres the thing, how do i tell the iMac to turn the screen off when im using the LCD side in the Dual Mode?

Go to System Prefs/Displays/Arrange and set the iMac in Extended Desktop mode (you are calling it Dual Screen) then drag the two display icons into your preference order and drag the menubar to your HDTV to make it the primary display.
Now if you use Front Row to view all of your media; DVD, Photo, Video, etc, when FR appears on the HDTV the monitor on the iMac will darken. Media that you view with iTunes should do the same. Some 3rd party multimedia apps may also darken the secondary displays when in Extended Desktop mode with multiple displays. I only use FR.

Connecting MacBook to HDTV Samsung

I am trying to connect my MacBook to my HDTV. I have purchased the mini-DVI to HDMI female cable and connected the HDMI female cable with another HDMI-HDMI cable to my television. The Mac and TV are reading each other, its just that only my background from my Mac is seen on the television. When I go to System Preferences -> to Displays there is a "Gather Windows" button that pops up, that is not present when the TV and Mac are not connected. When I push the "Gather Windows" button a window with the title "Samsung" pops up that looks very similar to the other "Display" window. I am wondering how to connect my Mac and TV so that everything from my Mac screen shows up on my TV. If I am doing something wrong, or need another cable, or anything else all help is welcomed.

Welcome to Apple Discussions!
In your Apple menu -> System Preferences -> Displays you should see two layouts of displays, one with a thick white line across the top, while the other without. The one with the thick white line across represents the display with the menubar and Dock, while the other without represents your display that doesn't have either. In this case, that should be representative of your TV. Wherever the TV rectangle is in relation to the Mac's rectangle is the assumed "position" of the desktop aligned next to the Mac. So if it is the right, you should be able to grab the titlebar of the window, and drag it over to the right hand side of the screen and have it partially appear on the TV if you keep dragging to the right. If it is some other placement, drag the window in that general direction. It may not instantly appear if your overscan settings aren't setup right. Also if you have a 1080i TV, you may need to switch to 720p resolution so that the overscan settings can be modified.

Trouble connecting MacBook to HDTV. SOS!!!!

In terms of connecting an original MacBook to an HDTV, will a miniDVI (not miniDigitalPort) to VGA adapter do the trick and send the video signal. I am hearing some confusion about analog and digital signals crisscrossing and I know nothing about either. I just want to watch my laptop on my TV..oh add by the way my TV has no composite hook-ins only component, HDMI, and RGB (whatever that means)

RGB is component.
Composite is RCA audio plugs with a Yellow video plug or S-Video plug.
With what you have on the TV you can use a Mini-DVI to HDMI adapter and an HDMI cable to the TV. This will give you video but not audio because there's usually no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.
You'll need external speakers or an external stereo system to hear sound since the Mini-DVI to HDMI adapter only carries video not audio. Plug the external speakers or audio out cable to the external stereo system into the headphone jack on the MacBook.

Trouble connecting MacBook to HDTV HELP!

I just bought a Belkin Mini DisplayPort to HDTV Cable. I want to connect my basic MacBook to my Samsung HDTV. I plugged in the HDMI side into the HDMI 1 port on the tv and I plugged in the other side to the mini displayport on my mac. My television does not recongize that there is an HDMI cord plugged in. When I go to sources and attempt to click on HDMI1 it says "This source is not connected. Please check cable again." Everything is properly plugged in and I've tried all 3 HDMI ports on my tv. I've also refreshed my tv to search for devices and nothing is detected.
Does anyone know a solution to my problem???
Is it an adaptor issue or is there a quick fix?
I've also tried to connect the cord to my roommates MacBook Pro and it still doesn't detect the HDMI cable.
Please Help!
