Spanning to HDTV through DVI to HDMI -

I posted it in the PowerBook G4 15" topic, but I think this would be more relevant to my machine...
My roommate has the 15" macbook pro that goes up to the same resolution as my 17" powerbook (1440 x 990)
How come the macbook pro is able to get 1080p on my Sony 40" Bravia (DVI to HDMI) and my powerbook, same resolution is getting a horrific 1080i result through the same digital cable? The only difference is that he has 256mb ram, as opposed to 128mb on mine. But as far as I know, my PB can span into the 30" Apple Display... so -
Why is it not showing 1080p with my PB?
Thank you...

It's the resolution of the screen that matters. The macbook can run any size screen at 1080P as I have tested it on my dads new sony panel that is native 1080p. Screen size in inches does not matter man. 720P is 720P no matter if it's 20" or 106" in my case. I run my macbook to my sanyo 720p projector just fine with the dvi connecter. Since your tv is hdmi you will need a dvi to hdmi adapter also so you can plug it in. It will look amazing! if you need a program to set display resolutions and tweak it I would recommend SwitchResX

MacMini HDTV through DVI

Hey guys,
I just bought my first mac to hook up to my HDTV... and the only resolution I can get is 680 by 400 or so. It looks terrible.
I have the MacMini hooked up to the HDTV through DVI direct... no adapters or anything. The TV is an RCA... I cannot for the life to me get the resolution set to anything that looks good. If I try 1920 by 1080 It makes me want to have a migraine and I cannot see the whole desktop.
Does anyone have any advice on what to do to fix this? I need to get it fixed ASAP or I will have to return it and I really don't want to Any help would be greatly appreciated! You can IM me on aim at dargonestielves or email me at [email protected] or simply reply to this! Please help!
Josh

This is the TV: got it on black friday for $474 lol.
http://www.walmart.com/catalog/product.do?product_id=4872141
Its model is RCA R52WH74...
I also tried a program called SwitchResX... but it made it anytime I have the DVI cable hooked up to the TV I get nothing but a garbled mess. I dunno how to fix that I did uninstall it though.
Thanks,
Josh

No video output from MacBook Air micro DVI to Polaroid HDTV via DVI to HDMI

Grrr! What's going on? The Apple online store finally sent me a micro DVI to DVI adapter and a DVI to HDMI adapter cable as well as headphone output to RCA adapter cables (for separate audio, since DVI will not transmit audio) and I hooked it up and - NOTHING! When I initialize the appropriate input setting on the Polaroid 27"HDTV the MacBook Air seems to get some sort of query signal as its screen flickers for a moment and turns to a grey screen for a couple seconds but then, that's it! Nothing! The Polaroid's screensaver remains and no signal, audio or video, is transmitted. Now, the micro DVI to DVI adapter is Apple proprietary so I don't think it is a DRM related issue where the chip might block the video signal coming out of the MacBook Air. The longer, DVI to HDMI adapter cable is by Belkin. Am I overlooking something? Could the new 27" Polaroid HDTV not be compatible with DRM protocol? I don't think so since all digital TVs equipped with an HDMI input are supposed to have DRM compatibility built in. What gives?

Well, BSteely, where to begin? After my extensive discussions with more than one support engineer at Apple in Toronto as well as in Austin an interesting picture is emerging. Seems that I'd omitted a few things: First, I was not trying to display HD content but rather standard definition content. Second, I made the mistake hoping for an elegant and easy solution in hookup via HDMI (new flatscreens don't even have a DVI port anymore) - bad mistake! As one of the technicians put it, HDMI is an "unsettled" platform when it comes to HDCP, currently in version 1.4 , meaning, I should have tried VGA instead, a "settled" platform after all. Now, whether this will work remains to be seen because I don't have a micro DVI to VGA adapter yet but suffice to say that in essence I've been getting the message from Apple that, yes, the MacBook Air will - in the near future - support HDCP, but for now it does not contain the necessary software simply because HDMI is in its forth incarnation; plus, as they put it, Apple can't be responsible for testing compatibility with every single HD television set on the market - while it is true that there are thousands in existence, at the same time there are only four versions of HDMI with different HDCP specs! So, while I may be partially answering my own query here, it seems that Apple at this point is not particularly eager to make this software available because they rather would like to sell their new displays with the micro DVI ports instead of us endusers being able to hook the computer video signal up to just ANY monitor or TV. In the end, it is my hope that they will reconsider and not forget who their customers are, maybe after the Christmas season....

Intel Mini - HDTV with DVI or HDMI Problems

Hello
With my Samsung LE32 and the Intel Mini I get overscan in HDTV resolutions like 1280x720, so I used DisplayConfigX to go from 1280x720 (overscan) to 1240x680
128 Front Porch 19
80 Sync 5
240 Back Porch 38
1688 Total 750
As you can see in the following images:

the image is pinned to the top left corner.
Playing with the Front and Back Porches seems to do nothing.
Any suggestions?
Thanks

The website for DisplayConfigX has a wonderful FAQ section that explains very well it's operation. Unfortunately, most of everything in that FAQ applies to displays that are based on CRTs with magnetic deflection systems. For example, the whole section on "How to get rid of overscan."
For a modern, matrix addressed technology such as LCD, DLP, LCOS, Plasma and whatever, most of the FAQ does not apply. It would be nice if the author updated the FAQ with such a disclaimer to stop giving people false hope that overscan, image centering and such things can be controlled by DisplayConfigX on their modern displays when almost certainly it cannot.
Can you possibly control overscan from your Samsung? Either directly through any user settings or, if need be, through a secret service mode? I think that will be your only hope.

How can I connect my Mac Book Pro (year 2008) to the TV set through HDMI? I've seen a DVI to HDMI iwire but I'm no sure that it is correct. Could anyone help me? Thank you very much.

I do not know the iWire adapter, but I use an inexpensive ($3) DVI to HDMI adapter from Monoprice, along with a regular HDMI cable:

Be aware that this will only transfer video. You Macbook Pro cannot combine audio through DVI to HDMI. You will need to listen to the audio through the Mac speakers, or attach speakers or a sound system to the Mac earphone jack, or determine if your TV has the ability to accept external sound from the Mac while showing video through HDMI (few can).

Macbook late 2009 mini DVI to HDMI not working

I never had a problem using my external TV with my macbook untill now. I always connect it using a mini DVI cable to HDMI to TV. It worked pefectly for a while. But recently it stopped working, when i plug in my macbook to TV it shows a blue screen for few seconds and then nothnig. there's no signal on the TV.
Any resolution will be appreciated.

I Started seeing this on my Mac Mini attached to my HDTV from DVI to HDMI after upgrading to 10.5.8.
I am running Spaces. Are you? Is it possibly related to this? I have seen a couple times where the screen was blue for some time and after pressing CTR-Left Arrow
to switch spaces, I would get my screen. Try switching spaces with the keyboard shortcut and see what you get.

Connecting to a Samsung TX-R3079WH HDTV w/Mini-DVI to HDMI

Greetings, I have a Samsung TX-R3079WH 30" HDTV that has an HDMI input (which works just fine via cable box input), and I have a Rev C Powerbook G4 12" 1.33 GHz with an nVIDIA GeForce FX Go5200 64 MB AGP graphics card with the mini-DVI output (which works with the converter to a 17" CRT via VGA).
I recently purchased a 4 m Radio Shack DVI to HDMI cable to connect the PowerBook to the Samsung TV. I am connecting the DVI cable through the DVI to Mini-DVI converter from Apple to the PowerBook.
At first, when I had the Mini-DVI/DVI connector attached to the laptop, I had the TV turned off and plugged in the HDMI cable to the TV. I turned on the TV, and my computer's display definitely recognized the external display. The problem initially was probably a refresh rate/resolution problem I guess, since the TV was reporting "No Signal" but the laptop definitely recognized an external display, which had its own icon in the System Preferences Displays panel (running at what looked like 640 x 480, definitely smaller than the native res 1024 x 768 of my primary display).
Anyhow, I didn't recognize what the problem was then, but now when I try and connect the DVI/Mini-DVI to the HDMI, all I get is incessant flashing from my primary display as it tries to decide whether or not there's something attached.
Any suggestions on getting this setup to work? Thanks in advance.

never mind found the mirror display function.

Mac mini will not recognize my hdtv through hdmi to hdmi

I just bought the new mac mini, got home super excited, hooked it up to my hdtv through hdmi to hdmi and nada.
I have a Vizio, 42-inch, 50/60 hz, Plasma TV. It was made in 2006 so there is no DVI port, it only has an RGB port other than the 2 HDMI ports.
I have tried both HDMI ports.
I tried turning everything off, unplugging everything waiting 10 seconds, reconnecting everything and turning the mac mini on first, then the tv AND vice versa.
Nothing.
My HDMI cable was kind of old so I went out and bought a new one from Belkin.
Nothing.
It does look like the TV is recognizing the device because it does not say "No signal", so it seems that the mac mini itself is not recognizing it.
I just bought this thing, it has not even been setup yet!
And I do not have another moniter here to hook it up to.
I tried calling Apple Care, but I called at 7:30 waited for 30 minutes for someone to tell me they were transferring me to tech support, then the phone rang for 10 minutes. I hung up and called back and they said the office was closed!
I am a die hard mac user, but I am at my wit's end here.
I guess my next step is to take it to the genius bar?
But I wanted to see if anyone out there has any suggestions/ideas?
(I know there are other discussions out there about this, but nothing I found actually helped my situation.
Thanks everyone.

I just got my mac mini as well and I'm having the same problem with my HDTV. Unfortunately I am not at home so I do not have the tv model on hand but it is a Panasonic from 05/06. I am trying to connect from the HDMI on the mini to the HDMI port on the tv and when it boots up the grey start upscreen shows up on the tv and loads for alittle bit than everything goes black. Any ideas?

Sound through DVI-D to HDMI

I recently acquired a refurbished Pavilion P7-1010 running Windows 7. It has no HDMI output, but it does have a DVI-D output. I would like to hear sound through my HDTV's built-in speakers (I do not have an external sound system or speakers). I tried using a DVI-D-to-HDMI cable, and get a picture, but no sound. Is it possible to send the sound out through the DVI-D port?
This question was solved.

Hi,
Unfortunately DVI-D port(s) only carries video signals NOT audio signals therefore you can not hear sound. You need something like this

There are many more around too.

Recently I bought a mini DVI to HDMI converter from eBay for my iMac 21.5 Mid 2011, but only later I realised that it does not have the mini DVI port in that. How can I connect my iMac to a LG smart TV through a HDMI cable?

This is the picture of all the ports from my iMac
This is the mini DVI to HDMI converter which I bought from ebay. And I have the HDMI cable to connect it to my TV
Could anyone please suggest me a solution how I could connect my iMac to the LG smart TV? Also I need to know if this transmits the audio as well to the smart TV?
Suggestions are welcomed. I really appreciate and thank you for your time

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404

Mini-DVI to HDMI output to Philips HDTV not working with Yosemite

I've recently upgraded to the Yosemite OS, and was surprised to find out that the output to my Philips HDTV no longer works. I have a Mini-DVI to HDMI converter, which I then plug into the TV. Before the upgrade everything worked fine (I think I was running 10.7), however now it just says "Video format not supported". I've tried every video format too...nothing seems to work anymore. With my friend's Windows laptop direct output via the HDMI port to the TV works fine, so it's not a hardware issue.
The Philips TV is an 8000 Series HDTV and I've already checked for the latest updates, but it says the software is up-to-date.
Anyone have a similar problem or know of any solutions???
Thanks in advance!

I would contact Phillips and see if they have a solution.
Ciao.

Macbook Pro + DVI to HDMI cable + HDTV = only 1080i?

Hi all,
I connected my MBP to my TV via a DVI to HDMI conversion cable ($24 from Fry's), but the highest resolution I am getting is 1080i (confirmed on the computer, and the system readout on the TV). Are there other settings that I missed (in the computer or the television) that I need to configure in order to get full 1080p out of this setup? Or is it the cable? Any help on the matter would be great!
I was hoping that the picture quality from the MBP to the TV would be greater, so being able to output 1080p would really help out. I haven't tried connecting via the DVI to VGA cable, but I'd really like to run this through my receiver, and my receiver does not have a VGA in, thus my want to use HDMI.
Also, is there a setting in OSX that allows you to close the computer without it powering down into sleep mode?
Computer: Apple Macbook Pro 17" High-res 2.4 GHz
Television: Sony BRAVIA V3000 46"
Receiver: Onkyo TX-SR605

Hi guys, I just got my Samsung LE40M87BD working on my MacBook Pro running Leopard in full 1080p resolution. Steps:
Install DisplayConfigX from www.3dexpress.de
Start DisplayConfigX
Select the correct monitor in the top dropdown list
Under Monitor, my settings are (mostly default):
Refresh rate 45.00-61.00
Horizontal frequency 10.00-120.00
Pixel Frequency 138.50 (specified in the Samsung manual)
Default refresh rate 60 (specified in the Samsung manual)
Under Resolution, I created a new setting:
Kind = Timing
H V
1920 Active 1080
48 Front Porch 3
32 Sync 5
80 Back Porch 23
Untick Interlaced if it is ticked!
Select Pixel Frequency and type in 138.500
Check the following (if the numbers are not correct, you have made a mistake above):
Check that Horizontal is 66.587 KHz (specified in the Samsung manual)
Check that Refresh rate is 59.934 Hz (specified in the Samsung manual)
Check 'Enabled'
Click Done
Go to Install, click Install
Restart the system as suggested
Your monitor not here? The challenge is to find the Front Porch, Sync and Back Porch settings that work for your monitor. The trick is to check if they are in the manual, and if not, assuming that the horizontal and vertical frequencies are, Google the horizontal and vertical refresh rates - they are pretty certain to yield the right settings! E.g. I Google'd '66.587 59.934 front porch'. Alternatively, try this if you are more technical: http://www.vesa.org/Public/CVT/CVTd6r1.xls
Hope this helps!

DVI to HDMI or VGA to connect to HDTV

Hi I am researching buying a 40-42" LCD or plasma TV and I would like to be able to connect my IMac to the tv. I will mostly be using the TV to watch sports and to watch videos from my IMac.
1. Will 1080p videos played from the IMac produce good 1080p picture on the tv? I have ATI Radeon HD 2400 XT with 128MB memory.
2. Or would I be better off just going with a 720p tv and playing 720p videos from the IMac?
3. Go with a DVI to HDMI or DVI to VGA cable? I understand I'll need to get a Mini DVI to DVI adapter also.
Thank you!

1 and 2. It should work with either a 720p or 1080p HDTV.
3. Mini DVI to (regular) DVI to HDMI. That will keep the signal digital all the way. VGA is analog. There are cables that have DVI on one end and HDMI on the other end. There are several types of DVI connectors, so be sure to get the right one.
NOTE: HDMI carries audio but DVI does not, so you will still have to run audio from the iMac headphones jack to the HDTV audio input separately.

MBP to HDTV won't work - mini displayport to dvi - belkin dvi to hdmi

Hey, I'm trying to get my laptop hooked up to my tv, using the apple mini displayport to DVI -> belkin DVI to HDMI cable setup (as recommended by the dude int eh apple store - which i knew and planned on doing anyway :P).
anyway, when i first plugged it in to the tv in my hotel room it worked, 1080p, then stopped .. then randomly worked again after a few ties. Once I got home i hooked it up to my sharp aquos 42 and worked fine, then after it was unplugged and tried to get it working again, it basically just.. wouldn't - i don't get a picture/signal on the tv, no options in the display cp , nor does the screen go blue when it normally finds a monitor/tv. i've tried plugging it in both ends, restarting, turning tv off/on, everything to no avail. I know the dvi-hdmi cable works, used it from a windows desktop to make sure. the mini displayport to DVI works for DVI 100% of the time into one of my monitors.
as mentioned it had worked at first on and off..., and now i cant get it working on my 1080p tv, nor the 720p one that's in my room, neither of them get a picture/signal; no options in display control panel either, or the quick display flash to blue. Furthermore, sometimes when unplugging the dvi cable from the tv i get the laptop screen flash, as when it picks the device up initially.
I never got my emailed invoice from apple when I bought the cables in in SF during macworld so I cant just return it to apple I'm sure.
any ideas would be greatly appreciated, please help this is making me go crazy... worked and now nothing no matter what i try. Oh, also tried on another, new user to see if it was a weird setting that got saved.
mbp running 10.6.2

I have the same mini display port adapter and Belkin DVI-HDMI cable (but a Panasonic 42" Plasma HDTV) so just set this up on it to see if I could duplicate your problem, unfortunately for you (but good for me) I can't.
I connected the adapter+HDMI cable before switching the HDTV on and then powered up the MBP. It (the HDTV) came up with my background right away (it's set at Mirror not extended Desktop) and when I run System Preferences/Displays get the following. Sorry but all I can confirm is that adapter+cable combination should work ...
Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys?

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

The mini dvi on the MacBook will only support video, in order to get audio you'll need to a cable from the sound out port to the sound in port on the TV.
