T61 Problem: Getting external monitor to display 1920x1080 through VGA

I've got the Nvidia 195.62 drivers, but windows still shows a max resolution of 1600x1200 for a 1920x1080 lcd screen. I'm using the VGA out.
This is frustrating.

Which windows version do you use?
I think if windows recognizes your monitor, it would be okey.

[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.

Can't get external monitor to work

I've used a Mac laptop for the last 8 years, finally decided to get an external monitor for home use.
I purchased a 25" Hanns-G HZ251. It's not working as I would expect it to work. I've got a standard DVI connection on my older MacBook Pro so I'm connecting via a DVI to DVI cable.
The only way I can get the monitor to display what is actually on my laptop is to have my laptop open and mirroring turned on. I thought I could have my laptop shut and the monitor would still work when connected, but when I shut my laptop it just goes black.
If I leave my laptop open but turn mirroring off, I get the generic purple Mac desktop, not my desktop.
What am I doing wrong?
There's an install CD that comes with it, but that only runs on a Windows machine. I appreciate any advice, I'm fairly technically handy but this is my first foray into using external monitors, so I'm definitely struggling to figure this out. Thanks.

You will have to keep them both open and play around with monitor settings until you get them both working. Keep doing "Gather windows" in System Preferences to get the display preferences window for the 2nd monitor and change it each time it doesn't display anything.
I don't know what it means "you will have to set it".
You have to set the desktop for the additional screen. Once you get closed clamshell to work, the external monitor will be your primary screen and you won't have to worry about it.

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.

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.

Problem with T61 and DVI External Monitor (via Advanced Mini-Dock)

Ever since I upgraded to Vista SP1 on my ThinkPad T61 (with an Intel integrated 965 series graphics card), I've been having problems when I try to use an external monitor via the DVI port in my Advanced Mini-dock. I'm curious if other people have experienced this problem.
The problems surfaces when I first boot up, or sometimes after my ThinkPad has been running for awhile (particularly when I do something graphics related, such as right-clicking to open display properties). The picture starts to flicker (or disappear and reappear, like the screen does when changing graphics resolutions). I also hear the "ba-bum" sound that you hear when disconnecting a piece of hardware, followed by the "bum-ba" reconnection sound - these two sounds happen repeatedly (sometimes as fast as once per second). If I don't do anything, sometimes I'll get a bluescreen.
Not long ago, I found a fix of sorts: to stop the flickering/reconnecting, I just open Task Manager and stop the process called "igfxpers" (an Intel driver problem). The problem always disappears after I do this, although I have to remember to do it every time I reboot or else the problem comes back. So it's not an ideal fix.
This problem doesn't happen when I connect an external monitor using the analog VGA port, or when I'm just using the notebook LCD. It's limited to just the DVI connection. I've tried two different digital monitors (one LG, the other BenQ) as well as two DVI cables - the problem is still the same. So it seems like a driver problem of some sort - unfortunately, the Intel drivers haven't been updated since last February.
I should also note that I've tried reinstalling my OS two or three times, and the problem always comes back. Has anyone else had this problem, and is a fix on the way?

Error Message:
Input signal out of range. Translation:
You will see this on an otherwise blank screen. Assuming that the data cable is plugged in correctly, the video card is feeding the monitor a signal stream in excess of what the monitor can accommodate. The two main causes for this are that the user has set either the resolution or the vertical frequency rate too high. For example, you might set a new graphics card to display at 1,280 x 1,024, but if the monitor is only capable of 1,024 x 768 resolution, you’ll get a Sync Out of Range error. This is especially common in 14-inch monitors.
Solution:
Because you obviously can’t make settings changes from within regular Windows, you’ll need to reboot into Windows Safe Mode. When you restart the system, there is a point during boot up when the system switches from reporting diagnostics and detected components to loading Windows. This point is usually accompanied by a beep and the screen going black. Just before this point, you want to start repeatedly pressing the F8 key. This should bring up a menu of Windows boot options. The one you want to pick is Safe Mode.
From Safe Mode right-click the Desktop and select Properties. Go to the Settings tab and use the slider to drop your resolution a notch or two. Reboot and let Windows try to go into Normal mode. If this still doesn’t work, go back into Safe Mode and get to the Settings tab of Display Properties. Click the Advanced button, go to the Monitor tab, and check your refresh rate. The lowest advisable rate is usually 60Hz, although this works better for LCDs (liquid-crystal displays) than CRTs (cathode ray tubes). Apply the change and reboot.

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 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:

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

Problems with External Monitor In XP

Ok, I've got a huge problem with XP on Bootcamp.
I've recently got a Samsung TV which I can use as an external monitor. This works absolutely fine when I'm using OSX, recognizes the TV and can use it as a second screen.
When I try to use the same monitor in Windows under Bootcamp, it works as an extension of my desktop, but not able to mirror my desktop. I want to do this so I can play my games on a large screen instead of a small one.
I've trawled the forums on this kind of problem and found a few answers. However, many of them talk about the ATI graphics drivers. I've downloaded the appropriate drivers and the control center from the website, but to no avail.
People have also said about going into display properties: settings: advanced and selecting the ATI tab. I have no ATI tab.
Also with the Catalyst Control Center, when I try to run it, it tells me that I dont have permission to change the settings and to contact my administrator, even though I am the administrator.
Does anyone have any ideas how I can solve this?
By the way. I'm connecting the external monitor via the DVI on my Macbook Pro to the HDMI connection on the TV.
Many thanks
Chris

My logic tells me, if you are using a new MBP the way it's designed is that even if you are plugged in at times it will go in battery mode for a few minutes in order to prevent battery damage, than it will recharge. This happens in the background without notice. However, within this couple of minutes you might notice your display screen to sleep because it is setup to sleep in 1 minute or less in the preference under battery mode. So within that window you might have your screen go blank since the entire process takes a lot more than a minute. I hope this helps.

Shutdown problems with external monitor

Hello.
I'm running Mavericks on my 2012 Macbook Air, running in clamshell mode with an Asus display connected from the Air's Thunderbolt port to the displays DVI port.
My Macbook will not shutdown, unless I disconnect the external monitor. This did not happen with previous OS versions.

What adapter are you using to connect the MacBook miniDVI to the VGA input on the monitor? Is it the Apple adapter made specifically for the MacBook or possibly an older version? Double check that you have the correct adapter, just to rule that out as the potential culprit.
Make sure you are using the recommended resolution and refresh rates for your monitor, from: http://www.viewsonic.com/pdf/userguides/va1903wb-2ugeng.pdf
Resolution Recommended and supported
1440 x 900 @ 60, 75 Hz (60 recommended)
1280 x 1024 @ 60, 75 Hz
1024 x 768 @ 60, 70, 72, 75 Hz
800 x 600 @ 56, 60, 72, 75 Hz
640 x 480 @ 60, 75 Hz
720 x 400 @ 70 Hz
other settings may show up in the Displays, System Preference, even though the monitor can't handle it. Try the different refresh rates to see if that makes any difference. When you have the Mac set up, then use the on-screen controls to auto adjust the monitor, I think this is the Auto Image or Auto set function.
I use a Samsung 204B, 20" at 1600x1200, and sometimes I get some brief flickering when first waking from sleep, but it works fine other than that.

X240 - Thinkpad Ultra dock Problem with external monitors

I have tried to connect my two external monitors to the dock (the one connected to the vga port) but it was only able to detect one of them (though at a low resolution) and not the other. i have tried using a replicator to connect the screen to the dvi and the usb ports but nothing seemed to work
Did anyone face the same problem and how were they able to resolve it - any recommendation for a port replicator brand / usb to vga display adapter to use that would work?
Thanks

Seems that there is no solution now, because DP MST should be implemented in Linux: https://bugs.freedesktop.org/show_bug.cgi?id=72795

Photoshop color problem on external monitor

I'm using MacBook w/ OS X Snow Leopard, NEC LCD2490 monitor attached, both displays calibrated. I found at some point that colors in Photoshop were WAY off on the NEC. Images looked "correct" in Lightroom on the NEC, but when opened in PS I had massive color shift and desaturation, e.g. purple flowers became dull gray-blue. I could drag the same image to the laptop and it appeared "correct" in both LR and PS. I checked color settings, etc. and couldn't find a problem, but presumably that would render the image incorrectly on both monitors. Most significantly, the image appears "correct" even on the NEC monitor when the laptop display is off (clam shell mode). Summary: Dual monitors: LR/PS correct on laptop display, LR correct on NEC but PS is WAY off. Using external monitor only: image displays correctly in both LR/PS. I suspect this is a hardware/firmware/OS problem vs. PS. Anybody else have this problem?

Snow Leopard has some known problems with color managing external monitors. We've been looking into it and notified Apple (as have a few other color management experts).

Problem with external monitor

Hello all,
did you ever use an external monitor with the mac book pro? Once disconnected the external monitor, the Mac freezes and becomes unresponsive. Do you know why?
thank you very much
Fulvio

I have the same problem with my external Acer monitor, starting today. Suddenly, when connected to my MacBook, the Acer monitor says "Input Not Supported". If the Acer monitor is not connected, it says, correctly, "signal not detected".
When the external monitor is connected, my MacBook can see it, has a display preference for it, lets me change resolution, etc, but the Acer monitor simply says "Input Not Supported". This just started today, and I did the system upgrade yesterday. Is there a connection?
I've tried the usual fiddling with connections, rebooting, everything.

How to get external monitor to obey Energy Saver settings

I have a 23 inch Apple Cinema Display connected to a 2010 15 inch 2.8 GHz i7 MacBook Pro running Mac OS X (10.6.5). I'm running the laptop in clamshell mode. Everything is working fine, but for one thing. For some reason the external display does not obey the Energy Saver Control Panel settings. I have the Energy Saver Control Panel set up so the laptop never sleeps but the display is set to sleep after 5 min. of inactivity. Unfortunately the external monitor never sleeps.
Anybody know how to get only the external monitor to sleep in clamshell mode?
Thanks…
Dragon Dictate in use. Occasionally mistakes are made. I correct the ones I notice…

Basically, reinstall the Boot Camp video drivers manually and if that doesn't work then go to the AMD/Radeon website and install the Windows drivers directly for your video card model.
If you want to do a search you will find others that have pretty good luck doing it either way.
