Why won't my second monitor work?

Hello,
I am new to the forum, as well as macs, and had a basic question I was hoping to get some assistance wit
I've got a 13" macbook pro, and cannot get a second monitor to run on it. I have purchased the Mini Display Port to HDMI adaptor, but when its all plugged up, its a no go.
The monitor (Samsung SyncMaster) will show activity when plugged with the HDMI (running through diff input sources) and the screen on the 'puter will go blue ...
After this, however, the screen on the Samsung remains blank and appears to be in sleep mode.
Any thoughts or suggestions would be greatly appreciated.
Thank you in advance,
S

On your computer, if you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with your connection. Try clicking Detect Displays just to see if the computer can now sense the presence of the connection. Check your cables and make sure the mini-displayport plug is pushed firmly in so that essentially all the metal part disappears inside the socket. Mini-displayport plugs can be a little tricky in that you need to make sure the plug is fully seated in their socket.
If you do have an Arrangement tab, and it shows two screens, then click Gather Windows to bring the second monitor's Displays preferences on to your main screen if the second monitor is not yet showing an image. Set the proper resolution. Set the refresh rate if that preference is shown. You should see a picture at this point.
Specifically which model Samsung SyncMaster?

HT4972 Why won't Kindle or instagram work on my I-Touch? Why do either of them require IOS 4 or 5?

Why won't Kindle or instagram Apps work on my I-Touch?
Why do either of them require IOS 4 or 5 and why can't Itouch V2 update to IOS 4 or 5 operating systems?

1. The developer stopped supporting older iOS versions.
2. A second generation iPod touch can be updated to iOS 4.2.1 but doesn't have enough RAM to run iOS 4.3 or newer.

HP envy won't recognize second monitor

I just purchaes an HP Envy 17t-j100 select edition notebook. I am trying to hook up a second monitor. The monitor is not the issue it works fine with the other laptops in the office however when i plug it into this one it wont recognize it and the screen on the second monitor just says cable not connected. I have a cord that is HDMI to plug into the computer and a VGA on the other side to plug into the monitor.

Hi,
Do you have a converter in between ? From HDMI (digital) to VGA (analog) you need a converter. Some "cord" may have builtin converter but some may not. Please check and get a right converter.
Regards.

Why won't my lock button work?

I went to lock my iPod and my lock button won't work. I can't even push it down, it's like stuck down in the hole but it won't pop back up. Everything works fine but I have to wait for it to auto-lock everytime I want to turn it off. Why won't the button pop back up?

It looks like you have a hardware issue. I don't know why the button doesn't pop up, but You can enable assistive touch. Assistive touch gives you a virtual lock button, so that will solve you problem. You can enable it by going to Settings->General->Accessibillity->AssistiveTouch->On.

Why won't my "if" expression work?

This calculation works:

If you want me to send you the table that I am trying to make this work in, just let me know. Thanks,

You do not have to load the airport utility.. a newer version is already included on the computer.

Why won't combined AND statement work

I want to exclude records based on two criteria's: status = 'M' and the status reason = 52.
The table contains records with status = 'M' and status reason other than 52.
Also the table contains records with status other than 'M' and status reason = 52 and I want to include those records.
I first tried using the statement below reasoning that placing the two criteria's in parenthesis would combine them and only exclude records with M 52
Where (nvl(Status_CD,'A') <> 'M' AND nvl(STATUS_RESN_CD,0) <> 52 )
However the query removed all records with Status_CD 'M' and all records with Status_Resn_CD 52.
Using the Where Not statement worked.
Where Not (External_Status_CD = 'M' and EXT_STAT_RESN_CD = 52 )
I’m curious why the first statement didn’t work?
Can anyone explain why the first query didn't combine the 2 statements but a Where Not did?
Thank you - Mark

Another way of looking at it:
The condition (x AND y) will be TRUE when both x AND y are TRUE.
If
sub-condition x is    nvl (Status_CD, 'A') <> 'M'   and
sub-condition y is nvl (STATUS_RESN_CD, 0) <> 52
then any row with status_cd = 'M' fails sub-condition x, therefore the compound condition is FALSE, regardless of status_resn_cd.
Likewise, and row with status_resn_cd=52 fails sub-condition y, so the compound condition is FALSE regardless of status_cd.
You used status_cd and status_resn_cd in one example; but
EXTERNAL_status_cd and EXT_stat_resn_cd in the other. That's quite confusing. Also, you'll confuse everyone (including yourself) if status is abbreviated as stat in some places but not in others. Either way is okay, but be consistent. The same goes for abbreviating external as ext; pick one or the other, and use the same word in all places.
Don't forget to check for NULLs. If external_status_cd and ext_stat_resn_cd can be NULL, you should say
Where Not (    NVL (External_Status_CD, 'A') = 'M'
          and NVL (EXT_STAT_RESN_CD,    0) = 52
depending on your requirements.

Why won't my HDMI output work after update my iPad to iOS6?

After updating my iPad to iOS6 it won't play my videos on my tv via HDMI cable. The tv displays "invalid format" I don't know how to chnage the display settings on the iPad because maybe there are none. Is there some backdoor way to change the settings so maybe I can use my $40+ cables I bought?

This is vatastrophic! I came to a congressional doctor meeting to give a lecture! It would't work!! Only iphone 4 projected muzzy picture and only on photo show!
Are they crazy? Why did they fricked it up?
Both were updated to iOs6!!!

HT2729 Why won't my video button work?

My photo button works fine, but when I press the video button, nothing happens.

Try closing the Camera app completely and see if you can record video when you re-open it : from the home screen (i.e. not with Camera 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Camera app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Why won't my podcast url work

I wan't to know why my podcast rss won't play. All my episodes show up, but they don't connect and play, all of my files are m4a except one, it is mp3 and that one plays. Isn't m4a the same as aac.

Why won't Verizon Messages app work on phone with Wi-Fi only?

I've successfully downloaded and installed the app from Google Play on a phone of mine that I only use wi-fi on. There is no cellular service to this particular device. It's set to airplane mode, with wi-fi on, essentially making it a 4.5 inch tablet, or like an android equivalent to an iPod touch. When I start the app though, it displays the screen shown in the included screenshot, and won't let me connect to the service, despite the fact that a wi-fi connection is present. I've seen that this is an issue that some others have had. I have Verizon service with my main phone, I'm not sure why the app that supposedly lets you access your texts via wifi will only do that on tablets or phones with cell service. Is there any way to get this working? Will there be any updates to allow the functionality that I'm looking for? I've read that it was present at one time, so why the change?

According to the Verizon website you are wrong.
Verizon Messages - Verizon Wireless
It states "
Use Wi-Fi to send and receive messages on your smartphone, tablet, PC, Mac and web browser"
I find personally that you are correct, is the website designed to mislead us? it is the same on the play store for google.
The difference is not just in one place, it is everywhere it is advertised. So it was meant to work but to charge customers the function was removed is my understanding.
