Disable overscan

I just did a clean install of Mountain Lion on my Late 2009 Mini. I use a 55" TV as the only monitor connected to the Mini and it is overscanning pretty badly. I do not have the option button to turn off the overscan feature. There has to be a way to do this without enabling Airplay, right?

I have the same issue. On my 2013 Macbook Pro running 10.8.2 I am connecting to a Sony 65 inch rear projection tv. The top and bottom of the screen are cut off. On my 2009 MBP running Snow Leopard, there is an option for overscan. When overscan is on it exhibits the same behavior as my 2013 MBP. When overscan is off, the picture displays normally. Is there some reason the overscan option isn't showing up in Mountain Lion? Unfortunately my TV does not have any settings which control overscan so I'm kind of stuck.

External LCD TV issues with Snow Leopard

Ever since I updated to Snow Leopard, my LCD TV is overscanning the image. If I Maximize Firefox, the outside controls are cropped off. This never used to happen in Leopard. I go to the display settings and disable "Overscanning" and it underscans the image leaving an inch of black space on the screen all around the image, which is more underscanning than it ever used to it.
Also, the image on my LCD seems a bit blurrier. I read about this issue and tried the Text Smoothing tip here http://blog.petersendidit.com/post/blurry-text-on-external-monitor-with-snow-leo pard/ but that didn't change anything either.
Any ideas?
Thanks!

There should be an underscanning slider in the Displays preference you can fiddle with (or is that what you were referring to?).
Does your TV have a "full pixel" mode (or similar words)? Does your TV have it's own overscan/underscan settings?
Which video card? How is the TV connected to that video card?

How to use tv as a mac book monitor

I AM TRYING TO HOW TO WATCH MY MAC ON TV SCREEN. I HAVE ALREADY CONNECT MY TV WITH MAC , WITH MINI DVI ADAPTER AND CABLE AND I SAW THAT THE MAC RECOGNIZE THE TV BUT I CAN'T SEE THE ICONS THAT ARE ON MY MAC ON TV. I CAN SEE ONLY DESKTOP BACKGROUND. WHAT DID I DO WRONG?

<http://support.apple.com/kb/HT5019>
Note: many TVs have overscan so you may miss the edges of the picture. This can be serious if the menu bar or dock go off the screen. Look for picture size settings on the TV. Some TVs cannot disable overscan. In that case, look for overscan or underscan settings in the OS X Displays system preference.

HP monitors not Mac compatible?

Hi all.
This has come up before (http://discussions.info.apple.com/message.jspa?messageID=10776106) and in other forums. You plug an HP monitor into your MacBook Pro (I'm using DVI) and the screen periodically flashes blue, but there's no recognition of the monitor. I'm using an HP 2159m.
What gives?

Just to leave a not-so-related solution here if anyone searches for "hdmi problems with HP 2159m."
In case anyone has an overscan issue (blurry text, underscan adjustment doesn't help, etc.) using the Mac Mini HDMI port, the solution is weird but simple.
Turn on your Mac and plug in the monitor and the image is crappy.
Turn off the monitor.
Press and hold the monitor's power button until the image shows up.
Try it a few times if it doesn't work. It works like a charm for me.
Thanks Apple for removing the "disable overscan" option from the display panel for PC monitors.

[Solved] TV overscanning - Now w/o Audio

I've recently installed arch and am fairly inexperienced with linux in general. I'm attempting to set up arch to work with my TV, however, it seems to be overscanning, and therefore cropping about an inch from each side of the screen.
I've been scowering the forums and this doesn't seem to be an uncommon problem, however, none of the solutions posted have helped.
This is what I've tried:
xrandr --output HDMI3 --set underscan on
However, this was the ouput:
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)
Serial number of failed request: 45
Current serial number in output stream: 45
I've seen other people who have had this problem, none of which have posted a solution.
I'm using xf86-video-intel as my driver. Also, my tv does not have a "PC-mode" option or any built in option to correct over scanning.
Any help would be appreciated.
Edit:
I've been experimenting with
xrandr --output HDMI3 --transform 1,0,-50,0,1,-30,0,0,1
Which brings the top bar into view, and aligns the left side, but the right side is not in view. I've been fiddling with the transformation matrix, but setting the first 1 to something like 0.9 or 1.1 doesn't seem to affect how the top bar is actually rendered.
Solution:
In the end I decided to run
xrandr --output HDMI3 --set audio force-dvi --mode 1920x1080
at startup. Edit /etc/gdm/Init/Default if running GDM for login manager. I placed mine at the top.
I don't believe the --mode switch is necessary. This does disable audio through the HDMI, however I have my speakers now connected through the audio port on my motherboard, and audio works great. Audio through all means but HDMI (that I tested) worked flawlessly.

I've continued doing research and I found something to fix the resolution, however, I lose all audio output.
xrandr --output HDMI3 --set audio force-dvi --mode 1920x1080
Any ideas on how to use this, but keep my audio functional?
Edit:
Found out why...

Catalyst keeps resetting overscan [SOLVED]

I installed Catalyst to get my Radeon video card to stop running so hot, and that problem was solved. Went from around 170 F to near room temperature. However, now I have a new problem...
Every time I start X, I have to start up the Catalyst control center again, and move the "Scaling Options" slider to the left and then to the right again -- it shows a proper 0% overscan value at first but isn't actually doing that until I reset it, it's actually back at its default, somewhere right between 15% and 0%. It then works properly until I exit X, and I have to fix it again the next time I start X...
EDIT: I cross-posted this topic onto the Phoronix forums and someone gave me the solution:

An apparently known issue for both platforms, indeed. Included should be the solution, from http://www.rage3d.com/board/showthread.php?t=33991741...
(Optional 9b. if you have black bars normally, disable underscan (always after lightdm has stopped): sudo aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0)]
I've found that you must restart immediately after this configuration in order for it to work.
EDIT(2): New update. From the linked thread:

I ran into this on my media center, which I'm using catalyst on until the power management improves on the OS drivers.
Thanks for this. I used set-pcs-bool instead and it worked.

How can I disable sending from one Mail account?

Hello. I have a gmail account that I use to subscribe to various newsletters and accounts. So it's essentially a read-only account for me. But I too frequently accidently send mail from that account. Is there a way to prevent mail from being sent from that account?

I want to do the same thing as the OP. I have tried making outgoing server none. And checking "always use this server so it prompts me to edit the message so that I manually select a different address to send from inthe drop down list. And selecting a different account for composing. Actually, all my outgoing emails keep coming from the one account I am attempting to disable. Got any other ideas?

Not null and enable or disable column in tabular form

Hi,
Using apex version 4.1 and working on tabular form.
ACT_COA_SEGMENT_MAS is Master table
and
ACT_SEGMENT_VALUES_MAS is detail table
I have entered 8 rows in master table and PARENT_SEGMENT_ID is column in master table which is null able. If i specified PARENT_SEGMENT_ID with value in master table then in detail table there is column PARENT_ID that should not be null and enable.
How i can enable or disable column when in master table PARENT_SEGMENT_ID column is null then in detail table PARENT_ID column should disable and vice versa.
I have created tabular form on Detail table. before insert into the tabular form Check in master table in first entry if PARENT_SEGMENT_ID is not null in first row of master table then in tabular form PARENT_ID should enable and not null able in corresponding to this first row id's lines in tabular form.
Same should check for second row in master table if PARENT_SEGMENT_ID is not null then entered rows with PARENT_ID into tabular form corresponding to 2nd id in master table should not nullable and column should enable in tabular form.
Thanks & Regards
Vedant
Edited by: Vedant on Jan 9, 2013 9:12 PM

Vedant,
You need to create you own manual tabular form and not use the wizard.
Using APEX_ITEM api you should be build you own form and you will be able to control how you wan to display the rows. (See Link [Apex Item Help|http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_item.htm#CACEEEJE] )
select case when PRIMARY_TABLE_COLUMN is null then APEX_ITEM.DISPLAY_AND_SAVE(3 , DETAIL_COLUMN ) else APEX_ITEM.TEXT(2,detail_column) end "ALIAS" from detail table
Hope that help.

NOT disabling keyboard/trackpad on tablet fold...

This is probably the opposite of user problems regarding the keyboard/trackpad and turning the Yoga Pro 2 in tablet mode... Here's the situation:
I'm a Java programmer and I'm sharing my files with my home PC, so I can work from my laptop or desktop easily without transferring files back and forth.
It's no fun adjusting my typing to multiple different keyboards for different PCs, and overall I tend to prefer a trackpad over a mouse for what I do which makes using my lenovo yoga keyboard ideal for everything (majority of wireless keyboards also aren't backlit).
I'm using the program Mouse without Borders (from the Microsoft website) so that I can use my lenovo yoga keyboard/trackpad on my desktop.
What I want to do: keep my keyboard and trackpad enabled when putting the yoga into tablet mode. I've already figured out how to disable the touchscreen for such uses, but the only way I know to keep the keyboard and trackpad active is to uninstall the synaptics driver/software. Obviously that isn't an ideal solution to have to install and uninstall it every time I switch between PCs.
Is there any way to stop synaptics from disabling the keyboard and trackpad when in tablet mode? Preferrably something such as disabling something in device manager, not uninstalling and reinstalling software depending my use for the moment.

Please provide more information.
First, I have no idea what "Jimi to Jimi" means. This is probably just something you need to explain to me; a Google search didn't turn up anything useful.
You said that the keyboard and trackpad aren't working right. What does this mean, exactly? Regardless, the monitor you use should have no effect on the function of your other peripherals.

Try to reset your password at http://iforgot.apple.com.
If that doesn't work, time to contact iTunes Support - http://apple.com/support/itunes/contact/

Got my password wrong twice and my mini is disable. I connected to iTunes, but can't get it to work. Can some one guide my through?

If it's showing the red disabled screen due to incorrect passcodes then you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808 - you should then be able to reset the iPad via your computer's iTunes and restore/resync your content to it

Disabled JMenuItem doesn show animated gif

Hi there
I would like to have a popup menu with actions that are enabled after they have finished with some background task taking some time. Basically this works fine for the enabling action on a shown popup. However, adding an animated gif as the icon or disabled icon does not show it in disabled state. In enabled state it works perfect. Please have a try with the sample code. You should see the disabled item for 2 secs and the icon is not showing up. After being enabled, it does. Invoking the menu again shows the animated gif in its last state left, but not moving any more.
I guess, repaints are not done appropriately in disabled state... Any ideas how to solve that would be highly appreciated :-)
Actually I used the icon at http://mentalized.net/activity-indicators/indicators/pascal_germroth/indicator.white.gif

The problem is that you are causing the EDT to sleep, which means the GUI can't repaint itself. Read the section from the Swing tutorial on Concurrency to understand what is happening.

How to disable IE Security Warning on opening a "local" visio file with Visio Viewer ActiveX?

Hello all,
Everyone knows that Microsoft released ActiveX based Visio Viewer for free and allow the users to open Visio drawing and view/print via IE browser.
The problem that I am facing is that some users are complaining about IE browser's security warning on "active content to run in files on My Computer".
It means that opening .VSD files from the network, internet, intranet would be all OK but if the user wants to open .VSD files from the local hard drive (or open it as a mail attachment, which will extract it to a temp folder), it prompt the user to select "Allow Blocked Content" EVERYTIME they open them.
I know that I can GLOBALLY disable this warning by going through Tools - Internet Options - Security section and enable "Allow active content to run in files on My Computer" but I hope that there is a way (or workaround) to allow them by file type or location, etc.
Questions:
1. Is there any way to disable those warning for all .VSD only while we still UNCHECK the option on Internet Options?
2. Is there any 3rd party Win32 based viewer which wouldn't have those restriction?
3. Is it safe assumption that McAfee VirusScan and Host IPS protection is sufficient enough to remove the IE's security warning feature?
Thanks in advance?
Young-

Are you able to host/launch the VSD file via an HTM page? In that case you can format the HTM page as shown below. This will trick IE into thinking it is loading the file off of a website. Commonly called 'mark of the web'.
