Re: iMac Monitor

What type of monitor is this? If it is an LCD screen, you may have some dead pixels. Please reply with some more details about your specific monitor.

SOURCE: thin yellow vertical line

Linear defects of this sort can be caused by a faulty display cable, a faulty LCD panel, or a faulty connector between the two. Much less likely is a problem with your graphic processor, since the line is static in appearance and position. Unless your Mac guy has lots of spare parts hanging around, I would suggest you replace the cable first, as it is the least expensive fix. If that doesn't do the job, then the display panel must be replaced.

SOURCE: Smudge, streaks, rays imac 24 monitor clean inside LCD

Yep, you can clean the LCD and the inside of the glass, but you will need two suction cups for glass. The ones for picking up window glass work. Lay the computer on its back. Place the suction cups at the upper corners and pull straight away from the table. The glass is held on by magnets and may have tabs at the bottom, so once the magnets are loose you may have to lift the glass away from the bottom edge. Be careful, it isn't safety glass and can break if dropped. The hardest part is keeping dust from getting between the screen and the glass during reassembly. Try working in a dust-free environment. I use two micro-fiber cloths, one with screen cleaner and one dry. You can't believe how much static builds up on the inside of the glass. It just sucks in dust. Don't wear fleece or you'll end up with fuzz as well. Stand your iMac up to reinstall. Clean the outside of the glass so you can see any dust on the inside. Place the bottom in place first. As you prepare to move the top into place, have light behind and above you and view the glass with the black screen behind. You can see most of the dust that way. Good luck.

How do I get my iMac to double as a monitor for my laptop?

Hi Mark,

You can't use an iMac as a 'monitor'. But you could use Apple's screen sharing.

On the MBP, go to System Preferences -> Sharing, and check the box for Screen Sharing. Now, on the iMac, in Finder select the MBP and then click the Screen Sharing button. You can now work with your MBP on the iMac. I do this a lot, you can even run the MBP in a 'Space' at full screen.

Two thin lines (vertical) one blue one yellow permenantly on screen.

Try to check first if the video card cause these lines..
Turn off your computer, replace the video card and check if the lines still display..

If you still see lines, check the cable connected on your monitor to the video card, see if its properly secure and not loose.

If you still see it... then my suggestion is you bring your monitor to a credible technician..see also if your monitor still have its warranty

Text in 2ndary screen not as sharp as IMAC screen

Prior to HDMI, TV screens simply did not have the resolution of the average computer monitor. With HDMI, they can approach or equal this resolution, but it isn't always easy to set up, and a certain amount of individual experimentation is necessary. Here is a guide I refer my own clients to when they are attempting this.

I have an iMac G5 2Ghz that when it start up you can only see video for a few seconds. I connected an external monitor and my iMac works fine but with its on LCD there is no video. I check the logic board...

The iMac G5 and iMac G5 (Ambient Light Sensor) computers have a video out port located on the back of the computer, which will mirror video. Video mirroring means you can see the same image that is on the iMac G5's flat-panel display on an external monitor, television, or projector.
Using the video out port, you can mirror video with a compatible VGA display using the Apple VGA Display Adapter.
You can also use the video mirroring feature with a television or projector that has S-video or composite video connectors when you use the Apple Video Adapter.
Both the Apple VGA Display Adapter (M8639G/A) and the Apple Video Adapter (M9109G/A) are available separately, and are needed if you want to use your iMac with a VGA monitor cable, S-video cable, or composite video cable.
The video mirroring feature is "plug and play". Simply connect a VGA display, television, or projector to the appropriate adapter (see above), then connect the adapter to the video out port located on the back of the computer.
When you connect the adapter to the computer, the screen may refresh momentarily as the computer prepares itself for the new video output. The computer tries to match the resolution of the built-in and external display. If there is no match, the computer changes both screen resolutions and may black out areas on the built-in display in order to match the capabilities of the external display.
Important: To ensure that your iMac G5 automatically detects the external display or projector, be sure you plug the adapter into the external display or projector before you plug it into the iMac G5.
You can switch resolutions and frequencies for both the iMac G5 flat-panel display and the external display, television, or projector using Displays preferences.
Want to watch a DVD movie disc on a television that's connected to your iMac G5? Select a 720 x 480 NTSC (in the United States) or 720 x 576 PAL (in Europe and other regions) resolution in Displays preferences.
Tip: Because of the display limitations of most televisions, the images displayed on a television screen are usually not as high quality as those on the built-in display or an external monitor.

Good Luck

Vertical line in imac 17" core 2 duo intel 2006 model

Attach an external monitor (you may need to buy an adapter to try this) and turn on Display Mirroring in the Display preferences.
If the same symptom shows on the external monitor, then you've got a video card problem. If not, I'd say you're screen has some kind of damage of failure.
Sorry, but either one is likely going to require a trip to the Apple Hospital.
At least with the display problem, you could use the external monitor until repaired.
