Using an LCD TV as the Macbook Pro display

Hey
I am trying to use a Samsung LCD Tv as the display monitor for my 15 in. Macbook Pro display. I have a DVI cord going from my laptop to a DVI-RGB adapter which is plugged into the LCD Tv monitor, but nothing shows up on the tv and the display is still on the laptop. Any suggestions?
Thanks

Assuming your adapter is valid, you try "Detect Displays" in System Prefs/Displays. Some people adjust the OS to show a monitor icon in the menu bar, near the clock, and you can access this from there also. If the Mac still detects no external display, suspect the cabling.
I really question your DVI-RGB adapter, though. That would be highly unusual - are you sure it's not DVI-SVGA, or DVI-component? Do you have the brand and model? I have run my Samsung TV from my MBP just fine with a SVGA cable and DVI-SVGA adapter.

I bought this computer with no disks, upgraded to Lion
Replacement System Discs can be obtained from Apple's Customer Support - US (800) 767-2775 for a nominal fee. You'll need to have the model and serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html
for some reason AHT wasn't installed
AHT is included in system disc #1.

HT203254 crack in the MacBook Pro display

Would a crack in the MacBook Pro display cause a similar "fade-to-white" symptom as a bad graphics processor?

A cracked screen (LCD) or the glass that covers the LCD? I'm a little confused what is cracked? Is your LCD operating with the crack?

HT3131 Is there a way to use 2 external monitors with the MacBook Pro in closed clamshell mode?

My internal display on my MBP is having issues and occasionally displays white lines all over the screen. The current external monitor displays properly. Is there a way to use two extrernal monitors intead of one external + the internal display?

Hi Mike, this isn't the first such problem report I've seen, perhaps another option...

About the hardware calibration system with the Macbook Pro display

I hope someone can help me out with a calibration problem I'm having. When I wake up my macbook from sleep (running OS X) the system automatically calibrates it and you can quickly see it switch from a blue tint to the proper colour profile. This is fine. However, I've installed Windows XP Pro via Bootcamp and the blue tint is there, the colours aren't right and this makes it particularly difficult for photo editing.
At first I thought it might just be me so I installed "VMWare Fusion" and ran Windows from a virtual drive. Since it was using OSX's calibration the colours were perfect. Is there any way to access monitor controls or a way to fix this? Software tweaks with the nVidia control panel don't make a difference. I've adjusted the gamma and had a go with the B/C settings but no luck. I think it is apparent that this is a problem with the firmware or something deeper than anything a software tweak could fix, judging by the auto-calibration during wake-up.

ctschach sez: "Well, you'll need a proper profile for WindowXP which will be loaded during the startup - there are no default profiles included in WindowsXP."
Yup! This is what is happening:
When you are in Mac OS X you are able to use ColorSync. In the Displays preference pane under 'color' you are able to choose or create your own color profile for the operating system to use for your display. When the OS is running, it is using your chosen display color profile.
Now you boot, via Bootcamp, into Windows. There is no ColorSync in Windows. The color profile your display was using in Mac OS X is still in Mac OS X. Windows hasn't got a clue about it. This has N O T H I N G to do with hardware. This issue is about getting a software color calibration profile for your display while you are running Windows.
So what does Microsoft offer in XP? It's time to go visit Microsoft to answer than question! I won't do your homework for you, but this will get you started:

Next issue: Is it worth buying a colorimeter for an Apple laptop? --> NO WAY!
(A) They are exorbitantly expensive.
(B) They are a total waste on a MacBook or MacBook Pro. The Apple laptop LCD displays cannot do 24 bit 'millions of colors' despite what you have read. They can only do 18 bit color (6 bits per Red, Green, Blue). The OS then uses dithering to fake the missing colors. Therefore, they are lousy for doing color management. The best you are going to get is a guestimation of what the image really looks like. You might as well just use what Apple provides for creating your own calibration in the Display preference pane under 'color'.
It would be much better to judge color with a calibrated Apple Cinema Display, which uses actual 24 bit color, or even better use a calibrated good quality CRT, still considered the optimum display for color management.
I have posted a brief dissertation about color management on LCD displays in response to a few queries in this group already, so I won't post it again. If anyone would like a copy, just bounce me a note.

When I open the MacBook Pro, display doesn't turn on!

I have a new MacBook Pro. It doesn't seem to wake from sleep. Also, when it is operating, it doesn't respond when I try and put it to sleep. Lastly, sometimes when I shut the computer, I notice that it will remain very warm for a long time in my bag, even though it isn't plugged in. These all seem very related.
Any Suggestions?
Thanks!
Tim

Welcome to Apple Discussions!
I also had some sleep problems with my new (in September) MBP running 10.4.10. Mostly a tendency to freeze if the display went to sleep, which does not seem to be the same problem that yours has. When I went to Leopard, all of these problems vanished.
Is yours asleep or frozen? If the sleep light is steady instead of pulsing, it may be frozen. And it should not freeze.
I have never had a problem with the MBP getting warm in my bag, but then, I always shut it down rather than put it to sleep. But I have heard of others getting warm. The MBP uses its aluminum skin to cool itself, and that doesn't work well in a bag. So I don't think it's good to put it in a bag asleep although I am sure others will disagree with this.
Since it's new and under warranty, you can always take these issues up with Apple.
Good luck!

Strange behavior of the Macbook pro display

Hi to all
I'm using my MacBook pro, and notice some strange behavior after open several windows or applications, I don't know how to explain, so here is a photo:
http://www.flickr.com/photos/86155326@N00/
I have tried: go back to 10.4.6 / create a new account / Hardware test... and Nothing.
Any suggestions?
Pedro

I am having the exact same problem(and no one is replying to my post either), I read in another post of someone who had a somewhat similar issue and someone commented that it was bad VRAM and warranted the logic board to be replaced. I'm hoping this is not the case, or at least hoping the problem does not get worse because I am in school and can't be without this computer for 2 weeks while it gets repaired..I'm hoping I can last til the holidays...

Sometimes I can make it go away by moving windows, and sometimes that makes it worse... this computer is only 100 days old...come on apple..help us out!

Using MacBook Pro display for another computer, is this possible?

I have a MacBook Pro and an older Dell tower, i would like to see if I can use an input on the MacBook Pro to view my desktop on the Dell without the use of another monitor clogging up my workspace. Im thinking firewire or something.... i don't know.... Thanks.

You cannot use a display built into a Mac as a monitor for another machine, as no Mac has a video-in port. You may be able to get a workable configuration by installing a VNC server on the PC and then using a VNC client on the MacBook Pro such as this one to control it.

Resolution of MacBook Pro display - always this fuzzy??

I should have done my homework, but...
I'm very sensitive to the fuzziness of the MacBook Pro display (especially the nearly grey and poorly defined letters on Word) and, to tell the truth, it's making my stomach turn and giving me a headache. I just received this computer through work, can't return it, and I'm stuck with it for three years now. what can I do or purchase to make the display CRYSTAL CLEAR (as in laser print quality)?
Will an external monitor help? Which one?
How can my iPod touch look so brilliant and this $2,500 laptop so archaic?
Thanks for any and all help,
Ants

The reason your iPod Touch looks sharper is that it has a much higher pixel density than the MBP. Your iPod's screen is 163 ppi (pixels per inch) versus 110 ppi for the MBP. However, if it looks very fuzzy, I would agree with the other responder that your resolution isn't set to the screen's native resolution (1440 x 900) or that you are zoomed in (press control and scroll down on your mouse scroll wheel or two-fingered scroll on with the trackpad).

Using the macbook pro with lcd drain the battery?

hello guy i bought a macbook pro 13 last week and according to what they say is up to 7 hours and im only getting like 5 just using the web or chatting or doing very basic stuff, i also want to know if using the macbook pro connected to the lcd tv drain ur batter y too. thanx

I cannot quite undertsand all you just said. Some punctuation to break up into sentences will help.
But if you are trying to say "I hope I did not spend so much for a product no beter than a Windows PC", then I think you will eventually find your $$ were well spent.
As I said, my work-supplied 14 in Windows PC laptop gets at most 4.5 hours. I get 5-6 under average use with my 15 in MBP.
Hang tight, you will firgure it all out.

Using a remote desktop connection with the Macbook pro.

I use the remote desktop connection on the Macbook pro and am unable to exchange info between the mac and the remote connetion windows. For example, if I am writing an email from the remote connection and want to attach a document, photo etc. that I created on the Mac, it just doesn't work. It seems like the Mac and the desktop connection are completely seperated eventhough they are both on the screen in front of me. the systems I use for work are not Apple compatible and will not work on anything other than windows explorer and in my case the remote desk top connection. Any ideas!

Try running in 'ClamShell' mode (MacBook Pro lid closed and using an external keyboard and mouse) with the Gateway connected and then run System Preferences/Displays, it should show then ...

I still don't know what happened to my test Aperture Library after the update to 3.4...Not only were my previews lost, but so were the original images! Needless to say, I haven't bothered to update the main library on the Mac Pro because I don't want to deal with this level of uncertainty (even with backups in place).

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

It's almost impossible. The new iMacs have a Target Display Mode, but it's built to do that. Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15. In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
By the way, I found your answer by searching this forum. I would suggest using the search function here in the futuere.

How does one continue to use Mail on the early MacBook Pro, Model 1,1, that is not upgradable to Lion? I have been running iCloud on my iPhone (OS5) and iMac (Lion) along with the MacBook Pro (OS Version 10.6.8)

How does one continue to use Mail on the early MacBook Pro, Model 1,1, that is not upgradable to Lion? I have been running iCloud on my iPhone (OS5) and iMac (Lion) along with the MacBook Pro (OS Version 10.6.8) since November until now. Mail will no longer download on the MacBook Pro and keeps asking for my password.

Mail should still be usable with your machine - but you'll need to update the settings to conform to the requirements of your system. Check with your ISP (like ATT, etc.) for the settings that will work with your Mail. Once you've updated this, you should be able to email like before.
For example, my ISP required that I go to Mail Preferences/Accounts and make sure the details conform to your email settings.
I have no idea of what your ISP is or what the settings might be, but this is likely the source of the problem.
