Dual-Screen (LCD TV) Is Being Cropped

Well, I've got my iMac plugged into a 32" LCD TV (I figured this would go in the forum for Mac OS X 10.5 instead of iMac, since it seems to be a software issue), and I've got the resolution set to 1920x1080 (although changing it to anything else doesn't fix the issue, anyway), and the screen gets slightly cropped.
Let me explain a bit more... Say I'm watching a video. On my main iMac screen, fullscreen, the character in-frame may have his whole head in the frame. Once I bring it over to my TV, it cuts off part of the top and bottom... It just crops it right off.
I've tried very hard to fix this... If anybody could help me out, I would be incredibly appreciative.
Thanks!
(Side note: I've checked... On the TV, I can't find anything that lets me resize the picture.)

I already tried turning off Overscan, but it just made the screen surrounded by a black box.
But, I've actually just now noticed on my remote a "Screen Mode" button (haven't looked at the remote in ages -- I've just been looking through the preferences in the TV), which I can set to "Zoom" to compensate for most of it, but it zooms a bit too much and it gets cropped again.
Now, it's not quite as bad as it was, so that is helpful, but there still is a bit of a crop.
It's fine with most things... It's hardly ever noticeable. But, when I use things like Boxy, it's pretty evident (because of controls on the sides of the screen and graphics on the top).
If this is the best I can get, it's still better than where I started, and for that I thank you, but I would like to know if I could eliminate it altogether (maybe like, an option in OS X that lets me manually resize that screen or something).
Thanks

This is something the app developer enables within airplay mirroring.
There is nothing you can do to enable that.

What options do I have if I want to set up a dual screen?

I have a Thinkpad T400 with a ATI Radeon HD3470 card. I am running the latest Arch x86_64 with Fluxbox and the 9.4 Catalyst drivers.
What is the easiest solution to set up a dual screen? Is there a way to do this without editing xorg.conf? Not that editing xorg.conf really is a big problem, but I will be moving around a bit and finding the correct settings for each screen would take some work. And I would like to see how far the dual screen development has come on GNU/Linux.
The way I see it the best way would be to have two screens with separate resolutions. Since LCD screens do not handle resolutions other then the native very well. So just stretching the screen makes the slave screen run the same height as the parent screen. Or am I wrong? It is not a problem running stretched if the screens run at the native resolution.
So, xrandr just gives me stretching. And the need of editing xorg.conf.
What about Twinview(just for nVidia) and Xinerama?
Is there other solutions?
SOLUTIONS:
There is arandr and lxrandr, both frontends to xrandr. Requires minimal xorg.conf editing. Only add a virtual line in the screen section. The virtual size does not have to be accurate, it only have to be bigger then the screens together. In my case, I have a 1440x900 primary screen and at most a 1280x1024 secondary screen. So my virtual size would be minimum 2720x1024. This is with the screens side by side. If the screens is one above the other it would be 1440x1924.
The exact size of the monitor is handled by xrandr(arandr or lxrandr). So, there will be no dead zone in the width(side by side solution), if the real height is different on the screen there will be a dead zone in height.
Using arandr or lxrandr means that you manually have to set this up each time the computer is restarted. To automate this, you can use xrandr. First do a
# xrandr
Screen 0: minimum 320 x 200, current 2464 x 900, maximum 2720 x 1024

320x240 75.6 60.0

to find out where the screens are connected. Mine are LCD and CRT1. Then test with
# xrandr --output CRT1 --right-of LCD
to see if you get a stretched desktop. If this works, just add the last line to your .xinitrc
This solution gives you stretching.

This works, and I get separate resolutions on the monitors. I tried using radeonhd but then the resolution on teh second monitor goes to some crappy values(which I figure are calculated proportionally to the 1280x800 one).

Any one help me with dual screen?

I am trying to get my LCD monitor work, which is plugged in VGA.
However, when i using "xrandr --output VGA --auto" to set it up, i get this failure "xrandr: cannot find crtc for output VGA"
i am using intel graphic card, and the result of "xrandr -q --verbose" is as follows,
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 2960 x 1024

how many monitors do you want to plugin? three? like damjan said, not sure if that works at all.
or are the hdmi outputs idle and you're just trying to plug in a second screen?
whats the exact problem? no output on that screen at all? or mirroring the internal one? in that case, try
xrandr --output VGA --right-of LVDS
(or left-of...)
can you plug that monitor in with hdmi? (adapter/etc) you might try that as well, maybe just the vga fails.
wow.. thank you konni... and thank damjan
i turned off HDMI-1, then I could get VGA work!
now i have dual screens, pretty cool.

Problem with dual screen (24" imac 2006 ver)

hi
i've got a 24" intel imac (2006 ver) and i've connected it using apple's mini-dvi => vga adapter to my 2nd 22" lcd monitor, a samsung 2232GW, which is set to 1680 x 1050.
however, the samsung lcd displays (when i'm using as dual screen) is quite blur and double imaged. quality is readable but very irritating. i'm also using the same monitor for my ps3 (uses the DVI side) and have no problem with any visual aspect. I've tried playing around with the settings like resolution and calibration and tuning but didn't help at all.
anyone might have any ideas and enlighten me on this issue?
thanks

Did you get any resolution to your question? I have the Samsung monitor almost like yours, and I posted two seconds ago. I think I have a similar problem. I had been using my Samsung with my PC, and just switched to Mac. I loved my Samsung, but now ,for the first time using as a second. Hooked up to mini dvi to dvi, and reported a glow, or tinge coming around any window that I may place on the Samsung.Also, when Ilook at the background around the window I can see that the resolution is not perfect and is breaking up a little. Did you try VGA? and did it help? Curious to know

External monitor simply not working - including with external dock (dual screen)

I can't get the external monitor (aka dual screen) to work on my T60 via the VGA port. My model is currently running Windows XP and has a ATI Radeon X1300 video card.
I'm 6 months out of warantee (although this problem started while in warantee but I can't convince Lenovo of that).
I've tried the following:
- ensuring "extend my monitor onto this desktop" in windows display properties
- disabling/enabling Presentation Director and trying all the schemes
- setting all different combinations of modes for resolution/colour on both (LCD + VGA) monitor
- trying two different monitors and cables (which did work with other computers)
- Updating the video drivers (from the Lenovo website) and Presentation Director to the latest versions
I then figured it might be a hardware fault, so I tried to see if the external monitor was activated on bootup. I made sure the "LCD + VGA" option on boot was selected in BIOS. Still no joy.
Finally, I figured the actual VGA connector was broken so I bought a compatible mini docking station (port replicator) and attached the VGA cable to that and even that didn't work.
What on earth could be wrong if it's not the software and not the VGA connector? The video card is working as its powering the LCD display?
Is my only option to give it in to repair (I can't afford that)?

Hi,
Does the external connections and cables work with another system. I'd do that first.
If all of it works with another system then it could be drivers or internal things but try that first.
There are some driver updates on the Lenovo site. Make sure your BIOS are updated and such.
Good Luck,
Yup, checked the cables and monitor with another system (actually with the same laptop using a USB->VGA adaptor which isn't a long-term fix)
Also updated to all the latest driver including a BIOS update (which I forgot to mention).
thanks,

X crashes on startup with AMD dual screen setup

Ever since I bought my AMD Kaveri A10-7850K at the end of January last year I've been having trouble getting a dual screen setup to work properly. Initially I put this down to poor beta drivers, and as I had far too much going on to investigate the issue further beyond some fiddling with xorg.conf, I bought an AMD A4-4000 as a temporary solution while waiting for the Catalyst drivers to catch up.
In June last year I decided to give my A10-7850K another go, assuming that the Catalyst driver would have matured enough in the meantime to cater for the Kaveri processors. Unfortunately the situation was still the same, and I I didn't have the time nor want to be swapping processors all constantly to I decided to just give up on a dual monitor setup for the time being.
After many years of using two screens, however, it is very hard to get used to a single monitor again, and as January is a quiet month for me I decided today to have another at getting it to work properly.
My setup is as follows:
an LG LG 23EA63V connected via HDMI as my main monitor at 1920x1080
a Viewsonic VP-171b connected via DVI as my secondary monitor at 1280x1024
AMD A10-7850K APU
Catalyst 14.12-1 drivers installed from Vi0l0's repo
Xorg 1.15 installed from Vi0l0's repo
KDE 4.14.3 using kwin
KDM is launched using kdm.service
KMS disabled via nomodeset
fglrx module loaded on boot via cat /etc/modules-load.d/catalyst.conf
Tear free rendering enabled
After plugging in my secondary monitor configuring it in amdcccle to be to the right of my primary moniotor in multi-display desktop mode, everything works correctly. This even works in my preferred setup where the secondary monitor is rotated into portrait mode, although I currently have not configured rotation so as to not overcomplicate the troubleshooting.
Upon rebooting, however, X hangs with a static white cursor in the top left hand of both screens, which after a while disappears completely. I then have to unplug the secondary (DVI) monitor and hard reset the PC before I can boot into my desktop again. The bizarre thing is though that when I plug in my secondary monitor again and configure it as desired, either through amdcccle or krandr, everything works perfectly again.
This is, of course, an incredibly cumbersome way of working, especially when most of the time I forget to disconnect my DVI monitor prior to turning on my PC, hence me just making do with a single monitor for the past 7 months.
I did a complete fresh install of Catalyst yesterday (uninstall drivers, delete remaining config files, reinstall drivers from repo), to no avail.

Using Keynote with Podcast Capture and Dual Screens

Hi everyone,
We are trying to use a dual screen setup to record some Keynote presentations using Podcast Capture (i.e Dual mode, with the Keynote presentation in one screen and the presenter in the other).
The problem we are having is that when in full screen mode, Keynote takes control of both displays, thus stopping the Podcast application from being displayed. Even if we switch off the Presenter Display on the second screen, the second screen turns black.
I know we can start and stop recording with hotkeys, but we would prefer to be able to see the Capture app in one window with the presentation full screen in the other.
Perhaps this is just an oversight on Apple's part, but I'm finding it hard to believe its not possible. If anyone else has a workaround then please share.
Thanks.

Other applications are not visible when Keynote is playing back. Keynote takes over control of the graphics system when playing back presentations to enable Keynote to display properly.
When I play back Keynote and I want to look at a second application, I use a second Mac.

MSI gtx 570 twin frozr III - Dual Screen Windowed mode issues

Ok, so... I was running a solo monitor 1440x900 resolution, i recently purchased a brand new asus 24 inch 1900x1080 monitor. Basically what is happening is when i play WoW or Battlefield 3 in windowed mode on the 1080p monitor the colors are not perfect. When i go full-screen on the new monitor no issues, but that is not what i want to have to live with. When i say the colors are not perfect what i mean is, for example when i look @ the sky instead of being a smooth transition or blend from one shade of the sky to the next it is bars or stripes of each shade as if i am looking at the sky in 8 bit color instead of 32 bit color. Another thing to note is that when i login to windows 7 the blue screen where i input the password has the same effect. The 1440x900 monitor is running everything just fine. the only issue is with the 1080p monitor.
I am using DVI cabling for both, and have swapped them around to see if that was the issue, and sadly it is not. I am running the updated gpu driver, which i uninstalled and re-downloaded and installed again tonight.
When i use the HDMI cable, that fixes the issue but i need the HDMI for my 42 inch tv.
Also in windows, just to cover my bases with this post, i have the native resolutions properly configured, as well as in the game for the given monitor it is being played on.
Anyone know of a fix for this?
i7 2600k
asus PBZ68-v Pro/Gen3
Msi gtx 570
Samsung syncmaster 953bw (1440x900)
Asus VS248 (1900x1080)
I am more than happy to re-explain anything that may not be as descriptive or clear to you just let me know!
EDIT!
When i run the 24 inch 1080p new monitor as my only monitor on the system, everything runs perfectly...
Edit #2
Ok so i have pin pointed a possible cause
This msi gtx 570 struggles with operating multiple displays with different resolutions, while dual screening with my 1080p television and the 1080p display, everything runs as expected. Having to also render a 1440x900 display is probably the reason i am having the graphic issues. Is there any type of utility, setting, or other fix to this type issue? also this gpu is certainly less than 2 weeks since i purchased i could get a different card to remedy this... any suggestion? if you suggest a different card can you say so with certainty that it will work properly under the condition in which 2 resolutions will be required?

Ok, the problem is fixed and Svet i skipped a step or two. I installed the new driver with the clean install to save time for an initial attempt. What is interesting is that with the Geforce driver, only one 1920x1080 resolution was available
The msi driver gave me 2 options, 1920x1080 and 1920x1080 (native). The latter resolution fixed the issue for whatever reason.
The solution to this problem is so easy, when i purchased battlefield 3 it prompted me to download the geforce.com driver and i did not think anything of it at the time, lesson learned.

Clipped screen on dual screen+compiz+nvidia

Hello everybody,
I am connecting an external display to my laptop. The laptop display is 1280x800, while the external display is 1280x1024.
NVIDIA is configured to run two separate Xscreens, opposed to the TwinView alternative.
Compiz works on either screens without slowdowns, but the lower area of the external display is black.
It seems that Compiz is running on each screen at 1280x800, and since the external display is larger, a black band is shown at the bottom. How do I configure Compiz to use the full resolution on the external display?
Metacity isn't affected by this issue.
Did you ever experience that? There's not much on Google about that (or too much, searching for compiz+nvidia+dual screen gives too much results )
Forgot to say: this applies to Compiz 0.7.8 and Compiz 0.8.0 upgraded today. Affects Ubuntu and Arch either using NVIDIA 177.x or 180.x.
Cheers,
eaZy

I still haven't found a solution, but I managed to work with Compiz on the main screen (in my case the laptop) and Metacity on the other screen...
I'm starting compiz with
DISPLAY=:0.0 compiz --replace --only-current-screen
and metacity with
DISPLAY=:0.1 metacity --replace
This is working, apart of small focus bugs: changing from an active window on a screen to an active window to another screen is impossible, the only solution is clicking on a unfocused object and returning the focus to the target window.
That's actually the work around I was looking for! Thanks a lot. I'm using a 26" tv as the secondary display and compiz is kind of pointless on that, at least to me. For some odd reason I've also noticed that when I set the larger display to a resolution lower than the main display (the laptop lcd), there is no bar with compiz. I don't know how solid this is because after a few restarts it went back to the intended resolution, but since doing the same step again it's been working for now.

Remembering windows positions when switching from/to dual screen display

Hello,
Most of the time, a second LCD screen is plugged in my Macbook and configured as the main display. When I arrange the windows, I keep iTunes or my mail application maximized on the macbook screen and use the bigger external screen for all other windows.
If I unplug the external display, all the windows are of course moved to the laptop display. When I plug again the external screen, all the windows are moved to the external display. But I would like the iTunes and mail application to remain on the laptop screen.
Is there any utility to remember the windows positions and arrange them automatically when I switch from/to single/dual-screen display?
Regards,
Raph

Would DisplayWatcher do what you want? I came across this a couple of weeks ago but haven't had the chance to try it out yet.

Keyboard/mouse focus mixup on dual screens

I've been using a dual screen i3wm setup for a few years now, with the dual screen configuration being done by xrandr in a script in .bash_profile:
xrandr --output HDMI1 --auto --right-of HDMI2
sleep 4;
xrandr --output HDMI2 --auto --left-of HDMI1
Recently I've started seeing a very weird issue: the keyboard will end up focused on one workspace, while the mouse will end up focused on another. To get them back in sync I have to mess around with the keybindings for moving workspaces (whereas before I've mostly used the mouse) or even had to reset i3wm entirely. I assumed this was a problem with i3wm so I switched to xfce, but had a similar problem - occasionally the focus would lock on a single application (e.g. Firefox) and I wouldn't be able to do anything else until I reset xfce.
Has anyone else experienced this?

I too experience this issue and find it annoying. It reduces the utility of the reports functionality. I would like to be able to open a report or two to monitor some activity with the auto refresh, while continuting to code or work through other issues in either sql or pl/sql pane. Instead the focus keeps getting sucked back to a visible report panel.

Dual screen hd cinema 30" on Win7

Hi,
I would like to know how to configure my apple hd cinema screen on windows 7. My computer is a macbookpro 15 and I want to use them like dual screen, at this moment I just see clone screens. I would like to have different application on each screen, I work with autocad. Is it possible to have different resolution on each screen ?

Anyone here can help me with the following? After trying to play a blu-ray film on my 30" screen I get an error saying my screen is NOT HDCP compatible.
What software are you using? Is it running under OSX? If you are using Boot Camp, try AnyDVD HD
<http://www.slysoft.com/en/anydvdhd.html>
It should work with a non-HDCP display.
Which I think is very strange, because i learned that this HDCP was just put on blu-ray discs to prevent copying it. How can you copy a disc on a SCREEN?
They are worried about copying the digital video from the DVI port. HDCP keeps it encrypted all the way into the display.
Before I bought the screen i looked at all technical details from the screen on the Apple website, and no where I can find it doesnt support HDCP.
No where does it say that it does support HDCP.
Why else call it HD CINEMA screen if you can play HD content on it?
It can display HD, just not encrypted DVI.
Is there a solution for this problem or did I just waste 1800.- ??
AnyDVD HD if you are using Boot Camp.
There are some 30" displays with HDCP, such as:

Problems with dual screens

I am running an iMac 3.06 GHz, 4 GB RAM, 512 VRAM. I also use an external monitor connected via HDMI. When I run Color using dual screens the picture shows almost only black, and what isn't black is so saturated I can barely discern what the picture is. Does anyone know why this is happening and/or how I can fix it?

I'm not sure Color works properly with monitors connected in that manner. Color isn't accurate without proper monitoring, and you can't get proper monitoring with an iMac. By proper monitoring I mean an HDTV or broadcast monitor being fed a VIDEO signal via a hardware capture card (AJA, Decklink, Matrox). You can't get capture cards to work on iMacs, therefore you cannot properly monitor a video signal.
The display in the Color interface is not accurate at all. It is just a reference to see what frame you are on. It isn't designed to be used to judge the quality of the image. It has a much higher gamma (midrange) than is seen on the external monitor.
I'm assuming the monitor you are using is being fed a converted HDMI signal...converted from the DVI or Mini Display port on the computer. Well, that is a computer signal...not a video one. There's a difference. So this setup will not work...not with Color.
Sorry,
Shane

IMac - Dual Screen Monitors. Windows issue

Hi,
I have an imac 27inc and a 27inc led samsung side by side.
I have connected the samsung to my imac and the dual screen works perfectly in the Mac operating system.
However.
When booting up in windows (using bootcamp) the samsung has black borders around the screen and is not displaying a full image ?
Is there a fix for this ?
I have connected the imac and the samsung through HDMI.
Cheers,

I sounds like Windows is not correctly reading the screen's capabilities. There should be something like a Control Panel to reset the screen resolution to the screen's best native resolution.
With CRT's there was a huge expanse of phosphor on the inside of the tube, and you could fudge the resolution quite a bit. With LCD, you have one "best" resolution, and if you don't hit it perfectly, you get fuzziness or black borders.
