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.

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.

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.

Running a tv as a second monitor

Hello all,
Just a quick question, I've just bought a dual 2.7Ghz G5 with the standard graphics card (everymac says its the Radeon 9650) and was just wondering if I could hook a HD TV to it to act as a second monitor.
Its a little decadent I know, but it would be nice. I haven't yet bought the TV, I'm in the process of upgrading everything and thats coming last.
Is there anything in particular I should look for - other than a dvi port etc. - or is this flat out impossible? Thanks in advance
Dije

And you do need to run audio separately, if you want the sound to come out of the HDTV's speakers. Although HDMI carries the audio signal, DVI does not. The HDTV will probably have a pair of RCA (red/white) connectors for audio in. Just get a mini-stereo jack to RCA adapter, and run it parallel to the HDMI cable.
I've done it, and it works quite well (converting from DVI to HDMI).

Trouble connecting second monitor (MBP late 2011)

Hi guys! I'm Nico and as you can see from the title i'm having problems connecting a second monitor to my macbook pro late 2011.
I have a mini display port to hdmi adapter that works perfectly fine (I use it with my HDTV), and because I also have an Asus external 22" monitor I bought a hdmi/vga cable
(http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=171010746825#ht_2700wt_1144)
so I could use my mini display port to hdmi adapter without buying another adapter.
This is what I do:
1- connect the vga cable to the Asus monitor
2- connect the other end of the cable (hdmi) to the mini display port to hdmi adapter
3- connect the mini display port to hdmi adapter to my macbook pro
But nothing works! My Mac is plugged to the power as well. I've tried to check in the monitor setting but nothing shows up, and even doing "detect display" still nothing works.
I've also tried to reset the pram. But without luck.
Any suggestions?
Thanks,
Nico

Any idea guys?

Second monitor Picture-in-Picture?

Here's what I'm using:
White Macbook 4,1 (2008)
HDMI cable
Mini DVI to HDMI adapter
HDTV
I've been using the TV as a second monitor. I know how to mirror the displays too; that's not what I'm inquiring about.
I would like the second monitor (TV) to be a picture-in-picture on my laptop. It would be cool to have a small, windowed view of the second monitor's activity on my primary monitor. This way I can do my work and watch TV in the other room, while my roommates watch a movie on the big screen. (I have a crazy long HDMI cable)
Any help or suggestions would be greatly appreciated.
Thanks,
-Dave

Sorry I do not know of any third party utility that can do that and of course there's noting in OSX to do that on its own.
Physically there is no way to get video in to your machine except maybe using one of the Elgato products.

Mirroring on second monitor. How?

Until we can use an external monitor, I am trying to mirror FCP X on the external monitor. I purchased a mini display to HDMI cable and it works. But...when I mirror the display, my resolution changes on my iMac. What is the proper procedure for doing this?
Best.
Tom

The two monitors have to negotiate a common resolution, so the same screen can show on both. That "same screen", or "mirroring" requires they both be the same resolution. This is normal. HDMI is not really the best way to get a second monitor hooked up, unless you're using an HDTV monitor. In which case remember that TV's, even HDTV's are of lower resolution than computer monitors, by a good magnitude.
So, do NOT turn on mirroring, no! What you want is for the second monitor to just be a second, non-mirrored monitor. Then in FCP X, go to the Window menu, and there you can chose to show the Viewer (my personal preference) or the Browser on the second monitor.
For even more real estate, I also set to use Full Screen mode at the bottom of the Window menu (Cntrl+Cmd+F)

Mini a1176 - 2.16ghz core 2 duo - second monitor

hey all,
recently picked up a used mini, core 2 duo @ 2.16ghz, model a1176 to replace my aging g5 and boy do i miss my second monitor.
i have seen usb video cards and was wondering if anyone had any suggestions as to what to get and, how it will impact the overall performance of the machine. i.e. if there are different options, which would run a second screen better with a better refresh rate.
any suggestion is appreciated! my budget would be sub $100 as i am also looking to upgrade the ram from 2gb to 3gb.
many 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.

Late 2008 model - Not Displaying Second Monitor

My logic board broke recently and I took it to Apple to get it fixed. Once it got out of repair, I picked it up and brought it home. Plugged in the DVI cable and it did not turn on. Turns out the display is there. I can move windows over to the second monitor, but it's not actually showing anything.
I have a Samsung HDTV and a DVI cable. It's worked before, so I know it's compatible.
The reboot did not work. "Detect Display" did not work. Adjusted brightness. Haven't tried using the cable on someone else's monitor, nor have I tried to use another DVI cable. I still have to look into these things.
I'm figuring that somewhere there is something I have to restart, but Google and the forums have failed me.

Haven't tried using the cable on someone else's monitor, nor have I tried to use another DVI cable. I still have to look into these things.
You know what you need to do. Go ahead and do it.

How to connect my Cinema Display as a second monitor

I just purchased a new 27-inch iMac, and I explained to the Apple folks that I had a 17-inch cinema display (silver clad model) that I wanted to connect, for a dual monitor set up. They told me just to get the Mini DisplayPort to DVI Adapter, but I was surprised to realize that's not going to work.
Can anyone tell me how to do this, and what connector is actually needed? I have the big old white power brick that I bought to daisy chain my old 17 and 23 inch displays with my old configuration (Mac Pro).
Or can you not have a second monitor with an iMac?
Thanks in advance.

Hi Cathy,
What connector is on that Cinema? ADC, VGA, or DVI?

Lightroom 5.4 jumps to second monitor when attempting to edit an image in Photoshop CS 6.

Hello,
I have a brand-new HP z620 with an Nvidia Quadro K 4000 display adapter and apparently a software and/or hardware conflict.
I am experiencing an issue with Lightroom 5.4 window not working correctly with my second, not primary, monitor. When Lightroom is working on the second monitor and I need to edit an image in Photoshop cs6, I want Lightroom stay where it is and Photoshop to open on my primary monitor. And this has worked well for me on my previous system which was also a Windows 7 64-bit machine with an Nvidia GeForce GTX 570.
When I click the Lightroom option to "edit in Photoshop CS 6” The Lightroom window will move itself to the primary monitor for no apparent reason. This is the problem I am seeking to remedy.
No other external editing programs opened through LR behaves this way, such as NIK or OnOne Perfect Photo Suite, and I really need LR to stay on the second monitor on the extended desktop.
I’ve tried every monitor cabling setup I could think of to try and even unplugging the primary to make windows identify it as the 2 monitor in the screen resolution settings, but that does nothing for me. My new workstation is running the same OS version and a K4000. Monitors are currently connected to the display ports via dp to dvi adapters. I’ve already tried moving the connections around and plugging one into dvi, there doesn’t seem to be a setting I can change within windows or adobe to change this behavior.”
On a related note, I have similar instability in software made by X-rite that supports the use of a colorimeter allowing me to build profiles for monitors and evaluate colors precisely. During the profiling process I place the colorimeter in the designated place on the secondary monitor and direct the application to begin showing the colorimeter different colors on that monitor. At this point the colors jump to the primary monitor while the rest of the interface along with the colorimeter is a secondary monitor. I have a workaround that I'm using for this particular problem but I am fairly sure that the issue that causes the problem with Lightroom is also the source of my trouble here and I need to eliminate it.
thanks for your time,
Larry Garvey

How can I use my Samsung 193p as a second monitor?

I am trying to use my Samsung 193P Monitor as my second monitor. It usually has great contrast and good color when attached to my PC. I plugged it into my imac using a DVI to mini DVI adaptor I bought at the apple store. Now it has awful color and the whites are a muddy grey. There do not seem to be any drivers to download. I've called Samsung and Apple and they have no ideas. It is at 1280x1024. Does anyone have any ideas for me? Is there a way to get the monitor communicating with my imac?? Thanks.

Thank you for the suggestions. I tried again. The thing about the Samsung 193P is that it doesn't have any external "buttons" to push for contrast and brightness. You are supposed to use MagicTune to do this, but of course, that is not compatible with mac. Without any adjustments, it usually looks great on a PC. Do you think I could use my Spyder to calibrate it with the mac? Could I only calibrate the 2nd monitor? I don't want to adjust the new mac monitor in any way. Would that be an option?

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
