PowerPC :: G4 Not Send Signal To External Monitor (Acer 22" LCD)
May 26, 2008
Having some trouble using my Acer 22" LCD with my 1.67GHz low-res Powerbook. It had always worked fine until I installed the Leopard graphics update, after which the LCD stop receiving a signal through the DVI connection. The OS will detect that a monitor is connected (blue screen) but it will not send a signal to the monitor. I read on the Apple discussion board that a lot of people with MBP's were having the same issue. Last night I reformatted the HD and went back to Tiger, updated to 10.4.11, and to my surprise the exact same problem persists. I know it's not an issue with the monitor itself, as my PC works fine with it.
The screen of my MBP 13 was shattered over the weekend, so I'm rigging up an external screen to tide me until I can fix the glass/LCD at the end of term. I have purchased an Acer P196HQL display and the MBP recognizes it, but the external display says 'No Signal'. I went to the shop in town where I was given a Thunderbolt/Mini to DVI-D convertor which then has a DVI-D to VGA convertor to connect to the external's VGA port. My MBP has Intel HD 3000 Graphics 384 MB graphics and is a GPU type, if that's relevant. I'd love to be able to revise for exams off of this laptop.
Info: MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)
I'm using an Envision 17" LCD with a Mac Book Pro, also have an Apple DVI-VGA converter in the mix. I know this monitor works fine with this computer but suddenly, I'm getting no signal.
Power cycling the monitor doesn't work; unplugging/replugging the video cable doesn't work.
Rebooting works, but if I try to change the resolution, the monitor stops getting signal. I know the computer "knows" the correct rez, but doesn't always offer it. I suspect a corrupt software component...
This monitor/cable works just fine with my 2009 MPro
Info: MacBook Pro, OS X Yosemite (10.10), 13", 8GB RAM
I just started using my MacBook with an external monitor, and love this new set up. But, I have a quick question. When I hook it up, my screen looks like an enlarged version of what's shown on my smaller MacBook screen. This is okay, but I'd like everything (dock, menu bar, etc.) to be the same size as on the MacBook screen, only with extra desktop space, if that makes sense. Currently, since everything is just enlarged, I don't feel like I have any extra screen real estate - windows and the dock take up the same amount of space relative to the screen size as they do on the MacBook. My resolutions are 1280 x 800 on the MacBook and 1280 x 720 on the external monitor. I tried playing around with different resolutions but keep getting a No Signal error on the monitor when I use anything else. I know this is kind of a difficult question but does anybody have any ideas?
I have my macbook pro connected t my sony xbr 9 tv, but the tv says there is no signal. however, the macbook pro recognizes the sony tv and it's resolutions. it connected through a mini displayport to hdmi adapter i bought off monoprice, and i don't think it's faulty as i used it in my living room tv thats also a sony.
I have a 15" Powerbook, and have just had an old mirror-door 867Mhz desktop Mac delivered. Is it possible to use the Powerbook's screen as its monitor? How could I connect the two?
I have a 17" G4 powerbook. I would like to get a display for it. Will i have to keep my laptop open if I am using the monitor? Or will I be able to close the laptop and still use the monitor?
I've been given (!) a G5 iMac which is practically brand new. It's only problem is that it suffers from the sudden shut off issue which seems to plague the G5 thanks to a faulty Power Supply and some caps on the mobo which get taken out by the PS. I've replace the power supply, but can't afford to get the mobo fixed, and since neither Apple nor any of the alternative operating system makers such as Linux will be supporting this system into the future, I figure that the hardware is essentially orphaned. I'd dearly like to use the screen though, as it's in great shape and is a beautiful display. So, my question is, can the internal screen be connected to an external source such as the video card of another computer? It would be great to use it for my music production machine. If anyone has any ideas, let me know. In the meantime I'm going to have a look around inside this beast and see what I can do.
I've got an old 20 inch blue and white CRT monitor connected to my last rev. Powerbook G4 with RAM upped to 1.5 gigs. I also have some peripherals connected to the usb hub on the monitor and all my ports on the powerbook itself are used up as well. Basically I'm running this mainly as a desktop. So, through the day while i'm working I get these blips on the screen randomly. they are horizontal blips almost as if I've just turned the monitor on. It is seriously about a millisecond. blink of an eye. anyways the freeze happens 99% of the time right after one of these blips AND while I'm holding the mouse button (usually manually scrolling in Firefox) it freezes for a second, i get the spinning beachball, but then it turns back to the arrow.
i can move the arrow all over the place, but i cannot do anything else. option+apple+esc doesn't do anything. the scaling effect doesn't work on the dock. i can't start or quit anything. if iTunes is playing, the music plays on, yet everything else is still frozen. so I open the lid and hold down the powerbutton until it shuts down. then i start up again. i have no problems when i use the powerbook without the external monitor. so is the monitor the culprit? Do i need to get a newer monitor? could it be a problem with usb 1.0 ports on the monitor and the usb 2.0 ports on the powerbook - a conflict of interest so to speak?
I want to run my g4 17 inch powerbook connected to an external screen with the lid closed, when i shut it the external screen goes off aswell, I have been told to use an external keyboard etc, I want to use a bluetooth keyboard and mouse. Is there anyway of doing this?
Hi- I have an ibook G4 (mid 2005). I'd like to be able to connect it to my new 22" external display so that I can have dual monitors. However, the external display plug obviously does not fit into the slot in the ibook.
Does anybody know the name of the converter cable I would need to buy in order to connect the external display to my ibook? And roughly how much these cost?
I had a monitor set up and working on my MacBook, but the monitor was crap. I disconnected it, and then re-connected it a couple of days later while I waited for my new one to arrive and found that my computer was no longer seeing my monitor. Since it was going away, I wasn't concerned and just figured I'd wait until I got the new one.
NEW MONITOR AND COMPUTER SPECS:
Dell 2209WA - Ultrasharp
MacBook approx 2.5yrs old Model Name: MacBook Model Identifier: MacBook4,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number Of Processors: 1
Connecting the two with a mini-DVI to DVI cable (tried a mini-DVA to VGA and that didn't work either - both the computer and the monitor didn't see each other)
PROBLEM DETAILS:
My computer thinks it is mirroring and/or spanning. In the display settings I can see both my laptop monitor and the new one and can even mess with the arrangement and turn on and off the mirroring.
My monitor however says ""there is no signal coming from your computer." and it tells me to touch keys or the mouse to wake up the mac.
I have the DVI input selected and I have tried toggling through the different input modes and still nothing.
ATTEMPTS AT FIXING:
I have restarted Reset the PRAM at start up unplugged and re-plugged in everything put computer to sleep, woken back up restarted with the monitor connected and WITHOUT it connected....
NOTHING is working.
I don't know what the problem can be and what I can do to fix it.... Any thoughts or fixes?
I have a 17" PowerBook G4. I am looking at getting an external desplay. Does anyone know if I can use the display with my powerbook closed? Or do I have to keep my laptop open?
I have a 24" dell external monitor that I use with my 17" MBP. My wife would like to hook up her 12" ibook to the 24" monitor. Is this possible, and what cables would I need?
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.
I'm looking to get an external monitor, a Samsung 20" . It is 16:9 ,1600x900 / I wonder will I have problem to get the optimized 1600x900 on it? I will be using the mirror mode. I've been using an old 19" LCD 4:3(died). I used mirror mode, and the LCD at ~1280 x 1024. I'm worry if I don't see the 1600x900 option in the display preference menu.
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.
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?
What a great place! I'm wondering if anyone has a solution to connecting a mini to the above TV.
I have the same TV in 32 inches and use a mini to HDMI cable that works perfectly. For some reason, the 40 inch TV says 'no signal' when I try to hook it up the same way. I've tried all the HDMI ports...including ones that work with other devices.
I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.
I have an ibook G4 1.42 ghz. It worked fine until recently. After connecting to a wireless network for a few minutes, it then begins to sporadically drop out. And after losing the connection, it can't detect any wireless networks. Turning off the card, restarting the computer, letting it sit for a few minutes... signals come in and out, but then drop again.
I'm using OS X.4, so this isn't a software problem, the OS, or caused by an update. The antenna also isn't faulty. The computer reads the card as being fully functional, but just doesn't detect any wireless networks. I've exhausted all software solutions and now can only conclude it's a hardware problem. Given the symptoms I've described, would the best idea be to replace the card altogether?
Just installed an Airport Extreme card in an iBook G4 (running Panther). Signal strength within a few feet of the wireless router (Netgear) is usually high to medium. But when I leave the room it's in the signal drops all the sudden. I haven't had much experience with wireless networking, so I'm not that familiar with this. We do have a lot of cables and wires related to the computers in the main room where the router is, could that be "blocking" the signal from outside that room?
I live where there are city-wide WiFi connections. I actually live a block or two from one of the routers. The only problem is that my powerbook 12" has the hardest time picking up a signal, in fact I often have a hard time picking up wireless signals unless I'm right near them.
I realize this is one fault of the 12-banger, but it's almost as if mine sucks more than usual. Anyways, I know there is a way to extend the wireless capabilities. I've seen hacks where an antenna is actually soldered on, which is a route I would rather not take. If I had a windows machine there are several USB adapters to extend the range. Are there any of these that will work with a Mac?
Sometimes while using my Powerbook in the house, the signal on my Airport connection will either drop completely or drop down to 1 bar which makes it extremely slow and barely usable. Normally, I'd blame the router, but the couple times this happened, I grabbed my brother's MacBook, set them side-by-side, and connected to the same access point, my PB had 1 bar or nothing at all, and his MB was at full strength and was working fine. Eventually, the PowerBook will go back up to full strength and be usable again, but after awhile, it will go back down too. It's an intermittent thing.
When I transfer large amounts of data over my Powerbook's wireless, I lose my bluetooth connection to my keyboard. Also my wireless signal decreases. Is there some way to fix this? I'm trying to backup a drive to my windows pc in the other room.
