Tecra M5 - External monitor detected but no picture

Hello,
I've just purchased Tecra M5 to use it with my external NEC monitor. However, whichever setting I try I get no picture on that monitor. The LED on the monitor indicates that it gets signal from the laptop but the monitor stays pitch black. The monitor obviously works fine, I've just disconnected it from another laptop.
I tried all possible settings in the nVidia control panel but no success. I also changed "Power On Display" in BIOS to "LCD + Analog RGB" but no luck either.
I have BIOS v.3.70 and graphic adapter drivers v.7.15.
Can anyone help?
Thanks,
Mike
P.S. When I press Fn + F5 I have no options to choose from, unlike with other Fn + ... combinations. I don't know wheter there should be any but maybe it is worth mentioning.
Also when I select "Only use one display" from the nVidia control panel and select my NEC monitor from the list, the monitor lights up and the LED changes to green, but the display is still black. As I cannot accept the changes the output switches back to the laptop display after several seconds.

Hi,
Thank you for a prompt reply and new ideas. I tried with Samsung monitor and used a different cable but the behaviour was similar - you could see the monitor reacting to changes (self-adjusting etc.) and there even were options to choose from when pressing Fn + F5 combination but the monitor remained either black (no signal) or blackish (sort of receiving signal).
I use Vista Business and I have that Value Added Package installed.

External monitor detected but no picture

I recently tried hooking up my 17 inch LCD gateway monitor to my 13 inch mac. My mac detects it and lists it under display properties however it does not actually have a picture on the monitor. The gateway just stays black or powers on and then goes black after saying no signal. I have a mini dvi to dvi adapter and then a dvi to vga adapter hooked up, which is then plugged into the monitor. My monitor has a dvi hookup along with the vga input but i unfortunately realized this after I bought the adapter. I figure if my mac sees it I should be able to get it working without buying another expensive cable.
Can anyone help?

I had the exact same problem with my 50" LG TV. I'll be looking forward to a reply.

External Monitor - detected but nothing showing

Hello
I have recently bought a miniDisplayPort-to-VGA adaptor so I could set up an external monitor.
Whilst in Display settings the second monitor is being detected, I just have a black screen/no signal.
My MB Pro obviously thinks its there, as the mouse travels off the side of the screen to the extended desktop, its just that nothing is showing...
I have tried a lot of things like restarts, altering resolutions, tried another monitor, tried other cables - and nothing seems to let me have an external monitor running.
Is there something I am missing here?
Thanks for any help

If two monitors have been tried and neither worked, that casts a lot of doubt on the adapter. Even though it is new, it could be defective. I recommend taking it back where it was purchased for an exchange.

Tecra A9 - external Monitor shows stripes when using the Laptop pluged.

Hello
I've heard about at least 3 Tecras A9 witch produces stripes on the external Monitor only when the Laptop is pluged. When using the Laptop with the battery, the Monitor works just fine. they tried to divide the cables of the Monitor and the power supply as far as possible, but still the same problem. When using the Laptop with a non-toshiba-AC Adaptor, the external Monitor is working fine.

Hello
In my opinion you should visit nearest authorized Toshiba service provider. They can connect your Tecra to external monitors and test it. If the result is the same I am pretty sure you will get AC adapter replacement for free.
Do not wait and discuss for days here. Contact them and I hope they will help you.

PB G4 1GHz - External Monitor flashing but eventually works

Something weird is going on with my Powerbook when I connect it to an external monitor.
When I plug in the monitor the Powerbook will detect the external display, but the external monitor will flash on and off, intermittently displaying the screen, but then cutting out.
With enough switching between mirrored and extended mode, the monitor will external will eventually work and the image will stay put. But if the computer goes to sleep, the whole thing happens again.
Is this just my video card acting up (no solution possible) or are there monitor 'drivers' out there?
Thanks!

Check if the connections are loose or get a new cable.
Do you use DVI-D (Stable) or VGA (Don't know) or VGA w/VGA to DVI-D transformer(Unstable: I use it for connecting my TV to my PowerBook)

Flaky External Monitor Detection

Anyone run into the problem where plugging in an External Display detects the display "most" of the time but not always. Often I'll plug in my external monitor and OS X fails to detect it. A reboot is often required and then it works. I'm assuming this is an outstanding bug with display detection in OS X.
Other info:
Usually book is closed when monitor is plugged in, then use wand or bluetooth periperals to wake Mac up.
I'm using the S-Video to analog adapter to connect to this monitor.

I'm having a simillar problem and it also happens just sometimes — most of the time there's no problem at all connecting to the external display, a LaCie photon20vision II.
The MacBook Pro is asleep when I connect the DVI cable for the external display. I also connect an ethernet cable, the power cable and an Apple USB keyboard with a Microsoft USB IntelliMouse. After that I press a key on the keyboard och click the mouse to wake it up. As I said this works fine most of the time. and I do this every week day, but today—and I remember it happened before—there was no signal for the external display. The light on the front of the MacBook Pro was static, so it wasn't asleep at least. Ater a while I opened the lid to see if there was anything on the "built-in" display, but no. I disconnected everything, tried to cles the lid to make the computer sleep again, which it didn't seem to wan. Tried to press buttons on the keyboard etc. but still nothing, even on the internal display.
Had to force restart.

PB screen broken-using external monitor now-but can't see hardware test

Hi. I have a 15" PB (1.33GHz) that was recently dropped. The screen was decimated... unusable and can see maybe the far left 1" of the screen... the rest is 100% unusable. So currently I am using a 19" monitor. I was wondering a few things... Is it possible to somehow disable the screen in the computer? I removed it, but the PB nows thinks there are two VGA monitors hooked up (?)... so I put the screen back in and I just sleep it everytime I start up and wake it with an external mouse so I can set my resolution on my external 19" monitor. It's not a huge deal if there's no way to disable it so that I can just remove the thing and the powerbook can be my keyboard
Anyway, I also can not run the hardware test because the F7 key (to mirror) wont work with it. Anyone have an idea what I can do about this? Somehow force the G4 to recognize the external monitor in the hardware test mode?? I suspect some other problems with the G4... such as a bad ram slot (the lower one) - it doesn't recognize any ram sticks that I put in there. I've read that lots of others had this problem... and even though I have applecare, I suspect that Apple won't recognize this since it has been dropped.
Any help is appreciated. Thanks

I assume this is due to the fact that system detects your internal monitor as default one, and that is there where system sends main data. In order to force system send data to the external monitor, get a mouse and physical keyboard, close MB lid, and then press any key on the external keyboard.
when you get there, go to system preferences/display, and manually move the Apple upper bar to the external monitor, then choose mirror; ultimately, set optimal resolution.

Tecra M5: External monitor flickers - grounding issue?

Hi,
I just bought a new Acer Full HD LCD Monitor (P244W) and have tried connecting it to the VGA port of my Tecra M5.
It works, but there's a noticable and increasingly annoying flickering. I tried it with both XP (SP3) and now Vista (SP1) and it happens for both. I have the latest BIOS and NVidia drivers. The actual laptop LCD screen still works fine, its just the external monitor that flickers.
To ensure there was nothing wrong with the monitor, I connected it to the VGA port on the ATI video card on my desktop pc and it displayed fine without any flickering.
After browsing the web for people having similar problems, I've narrowed it down to it being caused by my AC Adapter having a grounding problem as the flickering dissapears as soon as I disconnect the AC Adapter and just run from the battery. It the seems the common solutons to this problem are:
1) Try some different VGA cables with better shielding from interference.
I tried this and it made no difference. I tried cables both with and without the ferrite magnet/choke thingy's at both ends of the cable and the flickering remained.
2) Try different screen resolutions and refresh rates.
Tried setting some lower resolutions, but the flickering remained (besides I'd rather keep the 1920x1080 native resolution for my monitor). The NVidia driver only allows 60Hz for the refresh rate at 1920x1080, so I couldn't change this.
3) Ensure both the laptop AC Adapter and the monitor are connected to the same wall socket and are on the same power extension board.
Tried this, but didn't fix it.
4) Run an extension cable to another power circuit in my house and power the AC Adapter and monitor from this to see if its something wrong with the wall socket im using.
Tried connecting to a wall socket in my laundry, but didn't fix it.
5) Try using a different power extension board and ensure nothing else is connected on it other than the AC Adapter and the monitor.
Tried this, but didn't fix it.
6) Get a 3 prong to 2 prong adapter, so the AC Adapter is no longer grounded.
Most people on the web seem to say this fixes the problem, but I'm not sure how safe it is to leave it this way in the long run. Especially, when stories of laptops catching on fire are becoming more common.
7) Get a generic brand AC Adapter as these sometimes deal with the grounding problem better than the Toshiba AC Adapter.
Again, I'd rather avoid this option as even the generic branded ones are expensive.
8) Remove the battery and run from the AC Adapter on its own.
Tried this, but didn't fix it.
9) Fiddle about with the monitors settings.
Tried this, but none of the settings fixed it.
So, what are my options?
Is there a known cause & solution to this problem?
If my laptop is still under warranty, can I get a replacement AC Adapter or something to workaround this problem?
Thanks

I finally figured it out. Just for laughs and because it was the only thing I hadn't tried, I tried using a different 3 prong power cable that I had lying around, connected it to my monitor and the flickering dissapeared. *So, the power cable that came with my Acer monitor was dodgy and not my Toshy's AC Adapter like I first thought.*
I'm guessing the dodgy power cable was preventing the monitor from grounding properly, so instead it tried to ground itself using my laptop's power cable, going via the VGA cable
. This would explain why the problem seemed to go away whenever I unplugged my laptop's power cable and also why there was interference.

My external monitor works but I can't get my screen to work on my power book anymore

Can not get my screen on power book G4 to work but my external monitor works fine. Did I press something and turn it off?

rm44 wrote:
The both screens always worked fine but now the power book doesn't show anything on the screen. I didn't drop it or even move it. Where is the brightness button? Could I have hit it by mistake?
Thanks so much for your help.
F2 is the up-brightness button, F1 is the down-brightness button, usually, on PowerBooks. If for some reason the F1 button got held down for a couple of seconds, the display would go completely dark.
That being said, if the backlight does not come up (easily determined by seeing if the Apple outline on the cover is lit up) then the most likely suspect would be the inverter board, or the connection to the inverter board. If this is a Titanium PG G4, the inverter board is easy and relatively inexpensive to replace. For the Aluminum models, I don't know if that is quite so true.

External monitor recognized but blank

Trying to hook my Dell U2410 up as the main monitor. It sees it just fine and I can mess wit the settings, but the screen is blank. It does this in OSX and Win7 on the bootcamp side.
I'm running out of the display port to dvi.
I know the monitor is good as it is my primary desktop display.
Any ideas?

In the external monitor preference panel have you set it to NTSC at 60Hz ?
If you switch back and forth between Mirror and Extended Desktop does it flash at all ?

External screen detected but not working on DisplayPort connection on X220

I'm running up to date Raring on my Thinkpad X220 and stumbled upon weird problem.
I can connect to an external 24 inch DELL U2312HM external screen using DisplayPort cable.
I tried the same connection at work, with similar, but larger screen - 27 inch DELL U2713HM using the same cable.
When I check >>Settings >> Displays the display is detected. However I'm looking at dark screen.. Bizarrely - when I hit the PrtScr - I can also see it correctly with Ubuntu walpaper o_O
The monitor is detected and works correctly when using [DisplayPort to DVI-D Adapter Cable (Single Link)] however the resolution on this setup is limited to 1920 x 1200 so I'd really like to take advantage of DVI since the laptop should support it.
How could I fix this issue?

Hello,
According to the specs on Dell's web site, the U2713HM is a WQHD (2560×1440) resolution display and requires a DisplayPort 1.2 compliant signal. From looking at the PSREF documentation, this resolution is supported on the DisplayPort at a frequency of 60Hz. There is no mention of DisplayPort version, though.
Just to confirm, the DisplayPort cable you are using is DisplayPort at both ends and does not have an HDMI or DVI connector attached to the monitor, correct?

Older Apple HD Cinema Display is detected but no picture

Forgive me, as I know this is an often-asked question but I have searched and can't find a response that fixes the issue.
Yet.
So I have a Mac Pro (circa 2008) that works fine. The Apple Cinema Display is even older from about 2004 (I think).
Everything was working fine and I was video editing and Photopshopping to my hearts content.
I had noticed that recently the display would not come back from sleep without rebooting the computer.
So that might have been an early clue.
Then this morning I came home from taking the kids to school and the Mac Pro fan was running loud and no image on screen.
I rebooted the computer. This time the monitor displayed black and white vertical lines.
"Oh joy," thought I.
I rebooted again.
This time nothing but the heart of darkness.
Nothing.
I reseated the video card (as that has been a culprit in the past) and rebooted. Still no image. Did all the PRAM, unplugging the computer, waiting a minute plugging back in, plus all the other keyboard tricks one reads about. Still no joy.
I then tried the monitor on my MacBook Pro to see if it was a computer issue or monitor issue. No image from the MacBook Pro either.
The Macbook Pro did detect the display though and showed it along side theMacbook Pro screen is the Display Prefences.
I also ran the MacBook Pro in Traget Mode to the laptop so i could run diagnostic checks and repairs uisng Apple Utilities and Disk Warrior. No problems were detected on the Mac Pro (tower).
I then connected a Samsung monitor (that the kids watch Netflix on) and that worked fine on both the laptop and the Mac Pro tower.
So I have isolated the cause to the Apple HD Cinema Display. The video card and other hardware tested out fine.
Any thoughts on a fix or what the issue might be?. I can get by with Samsung as I am on deadline - but would rather have my trusty Apple Cinema screen back.
Many thanks.
And good karma to all who give it a head scratch.

Yeah I use my screen saver more often now and yes it's the white windows and desktop icons that ghost the most not horrible and my warrant is a few years past. The genius is wrong to accuse you that's just plain silly. The first apple 30 inch I bought had green lines and after a few trips to the store they sent it off to be repaired but in the end I think I got a different monitor back. Three and a half years later this started to happen. It's like short term burn and it's pretty subtle. I'm an audio guy so if I were a graphics person and this was my main rig I would be more upset. I just hope it does not continue to get worse. I have an older 22 inch with the clear plastic and it does not have the issue. It only starts to do it after it's been n for few hours.
Good to know I'm not the only one, thanks for posting.

FCP through to External monitor....Sound fine but video is still frames

Hi everybody
In January of this year this problem was posted by Andy D.....
+No matter what combination of settings I choose I cannot get video to play on my HD monitor only a still of the last frame shows up. When I hit play the audio is loud and clear and then when I hit stop the final frame appears on the screen.+
I have this problem but only when the material in my FCP viewer, canvas or sequence is ProRes422 (I'd converted H264s to this before importing into project)! If the project is DV or H264 material that has been rendered by FCP, it plays on the external monitor fine but it seems if we start looking at the high end stuff like ProRes, back to sound but still picture.
I might add here that the path to my external Full HD monitor is through firewire to an ADVC100 converter and then composite cables to the input of the monitor. By the way the same thing happens with an SD monitor.
I haven't tried using my video camera as the link through to the monitor instead of the ADVC100. Would this make a difference? I'd be pretty happy if someone had a solution for this.
Thanks in anticipation.

Unless the camera is a DVCPRO HD camera...like the HPX-170...this won't work. Not via HDV or AVCHD. Playout isn't as simple as it was with DV. There are far cheaper capture cards...Decklink Intensity Pro, Matrox MXO2 mini...but you need a MacPro for those (or with the MXO2 MIni, a laptop with an Express34 slot). An iMac is severely limited in what it can do.
Sorry.
#25 HDV external Monitor Viewing
Shane's Stock Answer #25 - HDV external Monitor Viewing
To view HDV on an external monitor in high definition you are going to need to purchase a capture card, like the ones Decklink (www.decklink.com) or AJA (www.aja.com) offer. They will both play out HDV in real time. The catch is that you cannot view this on a regular TV or NTSC monitor. Since this is HD, an HD monitor will be needed. HOWEVER, both cards are capable of down converting the signal so that it can be displayed on an SD monitor. This won't be color accurate
The real reason why you can't monitor HDV through a Firewire camera is because Firewire HDV cameras don't decode incoming HDV streams and route them to their outputs like DV cameras do.
Good options for you are the Matrox MXO2 mini...$450...coupled with an HDTV. Or a Matrox MXO (DVI connection) coupled with an Apple 23" display gets you good quality.
And there are the Decklink Intensity and Intensity PRO cards as well, and the AJA I/O Express...
You can, however, view HDV out via firewire as DV...lowering the resolution to that of DV, but still viewable. This is not full quality nor should it be used to judge the quality of your footage or used to color correct to. This is just a way to view the footage on a large monitor.
Here are some examples of some of the possibilities:
- DV or HDV sequence output to an SDI signal on a third-party interface
- An uncompressed NTSC or PAL sequence output to a DV FireWire output
- An HDV sequence output to a DV FireWire output
Sequence and output formats must have compatible frame rates. For example,
sequences with a frame rate of 60, 30, or 24 fps can be output to a 30 fps device,
but not to a 25 or 50 fps device.

MacBook Pro 13 + LG W2240T - No external monitor display

Hi all. Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.
Any hints or suggestions appreciated.

I'm having the same trouble. Actually, my Macbook detects the monitor but no signal is reaching it. I am using a DVI-A cable from what I can tell. There appears to be a DVI-D or DVI-2 type cable available as well.
The connection is as follows:
Macbook Mini Display Video output to (Mini Display/DVI adaptor) then the DVI-A cable to a DVI/VGA adapptor (sub-D monitor connector) to the external video monitor input. I can see a "No Signal" message when I use a "picture in picture" function on the external monitor screen but get just a black screen with the monitor set to full screen VGA input.
So do we think the trouble is the type of DVI cable or is there some further Mac secret handshake that I need to prompt the output from the Macbook. The odd thing (to me anyway) is that the Macbook recognizes the monitor by its brand and model number after doing a "Discover Monitors" search. But the signal does not reach the monitor and I don't know if there is anything else I need to do or if it just doesn't work.
Further info is that I just tried disconnecting the DVI input, which I use as the main video connection to my monitor and I get the stock "arora" screen image from the Macbook but that's not what is currently being viewed on the Macbook screen. So perhaps I can just set the Macbook to "Mirror" the displays and use the DVI connector. The trouble with that is that the DVI connector is occupied on both of my external monitors. I haven't even tried the other monitor yet as it's a plasma TV in another location.
What do you guys and gals think is the best and most cost effective fix here? I just want to be able to output signal from my Macbook onto the larger displays so that I can work more comfortably.
