PowerPC :: Undo Display Rotation On External Monitor Hooked To G4?
Jan 20, 2010
I read the thread about how to pivot your screen over in another section but it didn't address what to do when it goes wrong. And it did...very wrong. I'm running a Powerbook G4 Titanium 15" laptop with Tiger OsX 10.4.11 and I hooked an external monitor to it. I was playing around with the settings and saw the rotation feature, which wasn't available until I attached the external monitor. As soon as I clicked on 90 degrees, both the main screen and the external fritzed out. I could vaguely see things through the haze on the main screen but the whole thing had stopped responding to all mouse and keypad commands. Eventually the only thing I could do to regain control was a hard shut off with the power button and unplug the external. After that the main screen booted up just fine but the moment I hook up the external again they go blue screen of death on me and I can't see what I'm doing to undo what I did!! I tried hitting the manual reset on the screen itself, which I didn't really think would work but hey, desperate times...
After some research on the internet I found out that, contrary to what the other thread says, not all Tiger enabled computers can run the rotation function, apparently because the scan rate, or something like that is too low. Which is why the option was disabled when only the main screen was running. Nice to know and would have been good to know sooner but what I need help with now is HOW DO I FIX THIS MESS?!!!! Some sites mentioned archiving (I'm moderately computer savvy but I'm not totally sure I know how to do that) and some have mentioned the boot disk, which I have but I want to make sure I know what will happen if I do that. I've backed up my files just in case. Will it erase the programs I've installed or just my settings? Or is it much simpler and is there something in the utilities I can mess with that will reset stuff?

That said my problem is the internet is really slow when I connect my macbook to a my samsung 24" monitor. Super slow and when I disconnect, the internet is perfectly fine. I use [URL] to measure the speed and with the monitor I get usually around .05 Mbps to 3Mbps, without 12-19Mbps.

I have a 14'' iBook and recently bought an LG 19'' Widescreen monitor. I am testing a Dell 17'' on it right now before I open the LG one, but my problem is that the same screen shows on my ibook and the external. This isn't what I want. I have read you are supposed to be able to close the laptop and then it shifts to the external display but this is not working for me.
This is my goal:
Use my bluetooth keyboard full time
Have my ibook closed at all times
Have my external as my main display
How do I make this work?

My friend has a PowerBook G4 and he wants to connect it with an external 20" Apple Cinema display. His friend told him it was not possible to connect it, but I am not certain if this information is correct. He asked me to help advise him on this, but unfortunately I don't know enough about Apple hardware to give him the information he is looking for. I am wondering if anyone happens to know the answer on this.

irst off, according to mac tracker the Powerbook I have is the Powerbook G4 15 inch FW-800. I am running Mac OS X Leopard 10.5.6
Alright. About one week ago, I hooked up the powerbook to a 19 inch external LCD monitor with a DVI to VGA convertor, and all was well. It found my supported resolution and everything, worked straight away, etc.
Fast forward to today, at about 2pm (4 hours ago) I was using the computer and everything was working fine, but I had left it on for a few days so I shut it off when I was about to take a nap. I wake up from said nap about 20 minutes ago, turn on my Mac and my external display is only showing up at 800x600. I have no idea how this could have happened. This would not be an issue if my monitor's native resolution of 1440x900 were on the massive list of resolutions to chose from, but alas it is not.

Which MacBook Pro screen size would you choose for the following?
- Viewing 6 or more hours daily, not hooked up to external display.
- Will be my main computer.
- Used for work and entertainment, heavy emailing, use of iWorks software, light photo and video editing, surfing, no gaming.
- Will go with me nearly everywhere, home, office, cottage, travel. Used on desk, heavily on couch, deck, kitchen, bed, cafe.
- Price not a factor.
13, 15, or 17" screen, please vote in the Poll.

I was wondering if there was any way to force the rotation of a display on a GMA950 computer? If I hold any of the modifier keys when I enter the Display preference pane, it does not give me the option, although I know for a fact that the video card can do it, as it works fine in Windows. Does anyone know of a 3rd party app that might do this?

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.
Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

Just purchased an Asus MX279H monitor to connect to my 2012 MacBook Pro (OS 10.9.4). I'm using a 10ft DisplayPort to HDMI cable from CableMatters. Picture display is working great, but I cannot get the sound from the monitor speakers to function. The audio output cable to headphone jack doesn't work either. I've even tried to configure the audio device via the Audio MIDI utility on the MacbookPro. I can test the monitor speakers via this utility on the computer, but still cannot get the computer output to communicate with the speakers.I thought a cable would be a better option than using the VGA to DisplayPort Adapter.
Info:
MacBook Pro, Mac OS X (10.7.5), iTunes 11.1.3

I have an old iMac G4 and I was wondering if I could just use the screen somehow since I don't need to use it as a computer? Could I use it like a TV to play xbox or something?

For the past few months i have been using an external display hooked up to my 12" powerbook g4. I have had it on a dual display mode so no mirroring. Recently i would open the laptop lid waking it from being in sleep mode and my internal display will not turn on. The apply system profiler does not even recognize that the internal display exists. My external display works fine and has always been set as the main display. If i go to detect displays nothign happens. I have tried restarting the computer, instering system disks, unplugging the external and nothing has worked. I simply cannot get my internal screen to fire back up. When i used to unplug my external display the internal display would switch back to being the main display and everything would be fine. Now i cannot get the internal display to function whatsoever. Please try and help me as a need this laptop working and i will be ordering a mac pro soon for use with my external display.

Picked up a used mac mini from eBay to use as a HTPC. This is my first mac.
When hooked up to a TV the display has a blue tint to it. I have tried the 2 TVs in my house, both have the same result. It's so blue its not usable. When hooked up to a 20" 1440x900 reg monitor it looks fine.
Using DVI:HDMI cable & 1/8" audio

I know that the web have a lot of tips similar to this that i will ask, but i couldn't find no one exactly with what i want
I bought a new monitor, and mini-dvi adapter, an external keyboard and mouse to plug on my macbook
I would like to know how to turn off the macbook display without having to close it. I want to know that because if i don't close the macbook, both displays are on. If i close the macbook, the computer goes to sleep and then i press some keys on keyboard and the mac wake. In that point, if i open my macbook the display is turned off like i want. But i don't want to have to close the macbook all the time, and i don't want to leave the macbook closed because closed the temperature goes high.

When I hook up an external monitor to the DVI output, and use both the macbook screen, and the external, the display on the external is blurry, and not very sharp. However, when I close the macbook, and run it in clamshell mode, the external becomes very clear, and crisp (like it should). I never use dual monitors, so this really isn't a problem, but want to know if its normal. 2007 Macbook Pro, 2.4, 4 gig ram. Gforce 8600M GT

The text looks a lot different from the Macbook's display. I got it to 1080p and stuff - and yes, it's showing the full 1080p. But how do I get the text to look more like the Mac's text? My Macbook display looks so much sharper. The text on the Dell looks very not anti-aliased...it isn't thick, etc.

Is there a tweak out there that will disable the internal display while using an external monitor WITHOUT having to first close the lid on my macbook because I just leave my macbook plugged in for weeks a couple feet away from my desk and it's become a hassle to first close the lid, then move my mouse, then open the lid for better ventilation. I just want to leave it open and disable the display!

I recently got a PowerMac G4. When I viewed it Everything was working. Upon me hooking it back up I noticed It was not getting any picture. The Monitor was brand new so I did not figure it to be broken I checked the monitor on another computer and it worked great. From what I understand this is a common internal problem on the G4.

I recently replaced the video card on my G4 and now the USB ports on the back of my apple studio display are no longer functioning, but the monitor itself is functioning just fine. The USB ports on the tower are functioning normally.

I'm thinking about replacing my 24" iMac with a 15" MacBook Pro, however I'd like to keep my 20" dell monitor and use it as the primary display for the MacBook Pro, is that possible? By primary I mean having the dock and everything else on it, with the built-in display being like an external display that I can use for extra space. Also, would the same be possible at all with my iMac?

I plan to get a 13" 2.26ghz Macbook Pro, and I have a 20" external monitor with a 1680, 1050 resolution.
First thing, I've barely used OS X, let alone with an external monitor. How well does OS X handle it? Is it pretty simple, and can I set separate backgrounds for each display?
Secondly, will the GPU handle it alright, or will it be sluggish when I hook up the external? I'll mostly be using the 20" to do Photoshop work, with occasional video editing (though I have other computers available to do rendering on.)

I typed Mac Help about "to operate the portable computer with an external monitor attached and the display closed. When I close the display of my Mac Book or MacBookPro, the external monitor such as my 50" Plasma monitor or video projector would go black. I read the Help and it said and required the USB Mouse and Keyboard to close the Macbook display and put computer sleep. My question is will the Apple blue tooth or wireless keyboard and mice will work with out using the USB? Has any one try that? I am not sure if I should buy wired or wireless to operate this.

I finally did it... After a lifetime of Windows I've leapt from the Dark Side and am LOVING OSX... the combination of Spaces and Expose alone will save me countless hours!
I just got the VGA adapter to connect my spangly new MBP to the large monitor I used to use for my PC (no DVI capability on the large monitor, Acer x223w). Now however, I'm getting a strange and inconsistent problem:
If I connect all the cables and then power up, both my large monitor and the MBP screen appear slightly but infuriatingly blurry (see screenshot, left-hand side). If I power up MBP without connecting my large monitor and then 'hotplug' it (connecting the cable while everything is turned on), the blurryness is mostly cured - see screenshot right-hand side. The screenshot is from the same monitor in the two different states.

I'm looking to have a display hookup in my room for my Macbook Pro 15". I can't decide if i should get a 26" 720p HDTV with a pc input or a large lcd desktop display with a cable input to watch tv.
What are the pros/cons? Has anyone tried/preferred either? Any recommended monitors or hdtvs?

I have got my new uMBP i7. It is gorgeous, super happy with it . Because I need to run several programs under Windows XP, I have installed Windows XP under Bootcamp. I used Winclone to migrate bootcamp partition from my old MBP to the i7.My problem is that when I linked my external monitor (20 inch ViewSonic) to uMBP using the Minidisplay-to-DIV adaptor from Apple, there is no display on my external monitor. I can set the external monitor as extension of main monitor under "Setting", but after the windows Ding/Done sound, there is nothing on my external monitor. Does anyone have experiences about fixing this problem?

I am attempting to use an external DVI monitor using the mini port port and the mini port DVI adapter sold by apple. However the screen display on the external monitor does not match the Mac book display. All I get is a color Mac opening screen with no icons.apparently there is more to getting an external monitor going then just plugging it in.

I've read a lot about how the unibody alu Macbook have far better graphics than the old Intel graphics chips. My question is, however, what kind of frame rates do you get if you play games at 1900x1200 resolution on an external display? How do games like Unreal Tournament 2004, Civilization 4, WOW and others perform? Is it playable or should I get a Macbook Pro?
