G40, no external monitor screen display

I have connected an external LCD monitor (and tried a second) but the ext. monitor is unable to detect a signal.
Have tied the Presentation Director wizard and it can't see the LCD either.
It's possible that the ext. VGA port is damaged but unlikely.
Latest bios.
Anyone had similar problems?

I know that I'm probably grasping at straws here, but have you checked your BIOS settings?
Cheers,
George

HT5019 MacPro laptop display and 2 external monitors (three displays). Can I have more than one application displayed at a time?

I would like to have my MacPro laptop display and 2 external monitors (three displays). Question, how can I have more than one application displayed at a time? IE: I would like email on one monitor, Finder on my laptop, and iTunes on the other. Possible?
With extended desktop, it appears that I can only have one application presenting at a time. Sort of defeats the purpose of having multiple displays.
I am using the HDMI and the mini HDMI connectors.

[Solved] Can't get external monitor to display correct resolution

I have a laptop with 1280x800 resolution, I hooked up a spare monitor we had sitting around that has a native resolution of 1280x1024 to my laptop. When I hook it up the external monitor displays a resolution of 1024x768. I use KDE 4.5, so I tried to change the resolution for the external monitor in System Settings but 1024x768 is the highest resolution listed.
I've tried messing around with xrandr through the command line (somewhat anyway) but I'm at a loss in trying to get the external monitor to display its native resolution. I'd like to get the external monitor to possibly replace my laptop monitor as it would add another 224 vertical pixels. Anyone have any ideas?

You had said the native resolution is 1280x1024 -- I therefore assume this is an LCD monitor.
I would not generally expect LCDs to flicker. At what vertical frequency are you driving the display? Most LCDs operate at 60Hz. This is regardless of the local power line frequency or television standard.
Many CRT monitors are driven at 75 Hz to keep them from flickering or from "beating" with ambient lighting that is flickering at the local power line frequency (50 or 60 Hz). Again, this is not the correct thing to do with LCDs.
Bottom Line: Make sure your vertical frame rate is 60 Hz.

Try this: Use the [√]Mirror displays oprions, choose your resolution, then desect the [ ]Mirror displays.
It shouldn't supossed to be like this, but until they send an update, this workarround will work.

Can I use MacBook pro A1211 with external monitor, screen has died but

CCan I use MacBook pro A1211 with external monitor, screen has died but computer seems fine

Hmm seems like this model has DVI out. You could just plug a standard DVI monitor into that. Or use the DVI connector (VGA supported with included adapter; S-video and composite video supported with optional adapters) adapter that came w/ your machine.

External Monitor not displaying correct resolution.

I just hooked up my Viewsonic 19" widescreen display (1440x900) to my MacBook Pro. Ive closed the lid of my laptop and set the resolution to 1440x900 (60hz) in System Preferences yet the external display is still fuzzy. I looked in the monitors menus and it says its currently displaying 1152x864!!!!
When i tried mirror mode it looks like it thinks the external monitor is a different size but both screens have the same native resolution.
I've tried a bunch of different resolutions but none of them seem to use my monitors native resolution. I'm using the included DVI to VGA adaptor into the monitor. The monitor works fine if I plug it into my old Dell XP Laptop or XP desktop.
Does anyone have any suggestions?

Same "fuzzy" picture on external LCD attached to MacBook Pro here (2GHz, 2GB RAM, 10.4.11). Been using a mediocre NEC LCD72vx for along time and figured that was the reason, but I tried a stellar ViewSonic VG191b that I use with my Windows desktop for layout and found the same slightly fuzzy picture, despite also noting that the resolution setting was the native one. Note, I use the external display rotated 90, but I saw no change at 0 rotation. Straight DVI on both.
Half of the fun of having DVI out is its usefulness for layout in publishing. Powerful MBP, poor external display quality. I think some sort of fix is indicated here.

External monitor not displaying full 1920x1080 (black bars around desktop), Pavilion g6

I have a Pavilion g6 notebook running Windows 8.1. I have an external Acer S232HL display hooked up via an HDMI cable. The resolution is set to 1920x1080 in Windows, and I'm only outputting to the external monitor.
Windows thinks the resolution is set to 1920x1080, but for some reason on the monitor it is scaled to something like 1734x980 with black borders (unused pixels) all around.
All drivers and OS are up to date. Graphics: AMD Radeon HD 7640G via an AMD A8-4500M APU.
Somebody posted what looks to be the same problem for this AMD chipset, though for a different manufacturer:
https://forums.lenovo.com/t5/Lenovo-3000-and-Essential/G505S-doesn-t-full-screen-my-External-Monitor...

(Workaround)
Since I don't expect to find a fix for this, I've resigned myself to setting the resultion to 1776x1000 and setting the monitor in a 1-for-1 pixel mode (called "Aspect" in the options). I still end up with the borders, but the graphics are nice and sharp because it isn't trying to scale 1920x1080 into a smaller resolution.

External Monitor not Displaying

My notebook display is broken. I've had an external monitor hooked up for some time now. I accidentally hit something and the external monitor will no longer display. It's an HPG60-519WM. Is there a hot key that can turn it back on?
And another problem - my son hit something and turned the screen tint pink. How do I fix that?
Thanks

for the 1st issue:
press Fn + F4 or
win logo key + P
for 2 nd issue...

try to find a button on the monitor with "AUTO" written on it.... press and hold it...

External Monitor screen flicker fixed

I had a problem with my 3rd party external mornitor that kept flickering. It happened all of a sudden and was a constant flicker that was really annoying. Anyways, I discovered that when the mini-dvi connector is near my speakers(which are unshielded of course) It causes the screen to flicker. All I needed to do was move my mini-dvi connector away from the speakers(at least a foot away) and had no more issues. It was awesome when I made this discovery because I was paranoid it may be an issue with the mbp graphics card.

System Preferences > Displays
Select the "Arrangement" tab.
Drag the external monitor to the position you'd like it to be relative to the computer's own display.

Correcting external monitor screen resolution

I have a 27" iMac and have connected a Philips 160e as a pallette monitor via a Mini Display Port to VGA adaptor.
The iMac sees it but auto picks the wrong resolution 1280 x 1024 (stretched) instead of the Philips' 1366 x 768 @ 60Hz.
If I try to change the resolution the screen goes black which is symptomatic of using the wrong refresh rate, and of course I can make no further adjustments.
esc does not get me out of the black screen.
What is worse the iMac seems to remember the wrong resolution/refresh rate after restarts.
I have tried Safe Mode (it stayed black) and booting off an external hard drive into another system (back into black if I change the display settings).
Any way out of this loop?
I have gone into System Preferences > Display > Color >unchecked 'Show profiles for this display only' > selected > Philips 160E in the list
It only contains .icc profile information, which I suppose is to be expected but is the only access I can find to any specific model data.
The same display works fine with an older 24" iMac, using a different adaptor because of the different display port.
Somewhere OSX is storing the settings for the external monitor, I'd love to be able to trash it or change it back.

Yes but that doesn't seem to be the problem.
OSX is aware of the display, even its size.
It is available in Display > Arrangement and if I double click on the arrangement of the 2nd display I see the red highlight on the edge of my main screen.
I have managed to make the Philips display visible again by checking Show displays in menu bar and then changing its resolution back on the menu bar menu to 1024 x 768 @ 72 Hz, which is a wacky set and looks really stretched.
I have been considering getting a 24" Asus as a 2nd display but this is putting me off the idea.
Thunderbolt is just a non-conformist very expensive format that does nothing for the regular user a year after it came out. It costs extra for yet more adaptors which just add another complication to connecting peripherals.
Some days I just wished Apple would not find more sticks to poke between my legs when I am trying to get somewhere.

External monitor not displaying full quality

I recently purchased a Macbook Pro 15.4" Retina. I hooked it up to my Acer External Monitor via the HDMI out on the Macbook. My display settings are set to 1080p, however the display seems very blury and pixelated. I used to have a Late 2007 Macbook that I hooked up via mini display to HDMI and that displayed in perfect, crisp 1080p HD. Hopefully someone can help me figure out how to clear things up.

Have you had any luck fixing this issue Marcello? I had the same problem and found that the following fix worked for me somewhat:

Using External Monitor as display, and laptop for keyboard and track pad

Hi,
I have an aluminum Powerboook that is about two years old and I have it attached to a Samsung Syncmaster 203B external monitor. I have been looking for a set of instructions so that I can set the displays (I have been scouting around the preferences window and display options) to have the highest quality. At the present the words on my external monitor are a little fuzzy and I bet could be improved. Also, I've got the monitor and the computer set to be mirrored, but I really don't need the laptop window to be active. I'm just using it for it's keyboard and trackpad and it's sitting on my lap.
Thanks so much,
Rob Collins

Turn off mirroring if you don't need it. Set each display to it's native resolution. Your Powerbook is likely 1280x854, your Samsung is 1400x1050. Use the DVI interface.
Personally, I just dim my laptop when using the external display, although technically it's still active. Confuses the heck outta me sometimes when an app throws a window onto the laptop.

L440 Externer Monitor an Display Port Ruhezustand

Hallo,
wenn ich über Display Port mit einem externen Monitor (Asus PB 248) arbeite, dann das L440 in Ruhezustand versetze und ich es wieder starte, wird immer das eingebaute Display eingeschaltet. Der externe Monitor muss jedes Mal über "Win+P" aktiviert werden.
Bei einem Neustart oder wenn ich den Monitor im laufenden Betrieb einstecke, wird automatisch auf den externen Monitor geschaltet.
Kann man das irgendwo einstellen, dass immer beim Erwachen aus dem Ruhezustand direkt der externe Monitor eingeschaltet wird?
Danke vorab für Tips!

You are welcome!
All of the iMac models from Early 2006 thru Early 2008, had Mini DVI ports for video output.
All of the iMac models from Late 2008 thru Late 2011, had MiniDisplay ports for video output.
All of the iMac models from 2012 and later, have Thunderbolt ports that serves as both high resolution display output and/or high performance data transfer.

Windows 8 on boot camp on MacBook Pro retina w/external monitors = screen resolution not correct

how do i calibrate external monitors resolutions individually in windows 8 (like can be done in OS X) so that my MacBook Pro retina text isn't teeny tiny and my external monitors look normal? Is there a way to set the resolution and text size for each monitor separate from one another in Windows 8? Thanks for the help.

In Windows 8 use the help menu and search for external display.
