Split screen on the monitor

My monitor is split into two pictures. i know most monitors have settings that allows you to do this. but its split in the most inconvenience of ways. it splits horizontally and shows half of the picture and when you go into the settings theirs no way of changing it. i'm wondering if this a simple wiring problem or a component problem.

SOURCE: image set up of screen is only half of the monitor

If you v-size is already at 100% then the issue is with the picture being sent to the monitor. Based upon what kind of input you have for the monitor there is a number of different ways to fix this. I will assume you are using the monitor with a desktop computer. If this is for XP, then there is a simple fix as follows, adjusting your display properties:
Right-click on your desktop background and then click on "Properties" this will open up a new window. Select the "Settings" tab, then drag the green arrow in the "Screen Resolution" field to the desired setting. Since you have a "widescreen set-up" you more than likely have a resolution where the first number is about twice the second number...they should be close to even to have a square image (bigger numbers show more detail than smaller numbers).
Hope this helps!

SOURCE: hi, I have my macbook connected

Hi There and Welcome to Fixya.

Connecting a monitor to your MBP gives you more space to work on. You may want to check on the following and see if it was done properly :

  • Ensure physical connection - either mini DVI or mini DVI-VGA will work
  • Turn on the mirror mode by pressing "F7" or "Fn+F7"
  • Adjust the resolution of the monitor through the system preferences or the "Display status" in the menu bar
  • Put the macbook into "Sleep mode" to obtain the full (optimum) resolution on the AOC monitor
  • Keep the lid of the laptop open to access kybd and track pad
  • To boot the computer using the AOC monitor, turn on the computer and close the lid of the laptop at once.
Please let me know if this wont work.

Thank you for using Fixya.

Hello, 2 monitors running off d600 loptop one moniter not picking up windows wat is the problem help p'se

Hi. I hope this helps.

You need to open display properties, click on advanced, and make sure that the video adapter settings are configured to allow more than one monitor. some diplay adapters will only run on one monitor, some will allow cloning, where the same thign is displayed on both monitors, some allow span, which allows the total display to be split between the two monitors, and another setting to allow one to be the primary, and the second monitor for applications.

Also, check to make sure that on your power settings, you don't have it configured to power down monitors if not active. This can sometimes cause the second display to shut down when there is not an active signal going to it, and upon resumng it can cause the second display to not restart as it is supposed to.

Also, check each monitor seperately, having only one hooked up at a time, to ensure that the monitor isn't the problem. This is especially true if you are using flat screen monitors. They are notorious for working one minute, and the next they just quit. Almost all flat screen monitors..i.e. lcd, plasma, and dlp have capacitors that precharge to energize the screen, and those capacitors are quite prone for going out without warning.

I hope this helps you out.

Cant get any sound on tv


The only computer (or laptop) connection that carries both video and sound is HDMI. If you do not have a HDMI/DVI connector on the back of your computer, then you will have to use the VGA-composite or s-video connectors to display your PC's output on an external monitor like an LCD TV.

On both my HP and Dell laptops the display settings (Start/Control Panel/Personalize/Display Settings) allow two modes - single or dual monitor mode. Single monitor mode allows me to switch between any one of three possible video outputs - VGA-composite, S-Video or laptop screen, or a split-desktop (display spread over two separate monitors). Dual monitor mode allows the same display on any two of three possible video outputs.

Switching is performed using the fn keys on the keyboard (fn key plus the F2, F8, etc. function key with the display marking). You guys use single monitor mode until you figure out what your are doing. Select VGA-composite or S-Video.

Non-HDMI sound to your TV monitor or sound system must be obtained from your laptop's Headphone or S/PDIF jacks. Headphone is stereo and S/PDIF is 5.1 surround sound. Headphone is electrical, but S/PDIF may be electrical or optical (laser light). You must set the sound jack that you intend to use as the default on the PC control panel (Start/Control Panel/Sound).

None of these connectors is two-way in the context of an LCD monitor - your PC cannot record a TV picture or sound from the external monitor. To accomplish this you must purchase a video converter box that converts cable TV or video + sound inputs to USB format usable by your laptop. Do this and you can turn your laptop into a Tivo recorder/DVD burner using Beyond TV, Sage TV or a variety of other software packages.

Please let me know if you have any further questions or concerns.

Lcd screen is split howing the whole picture

Check the same in bios if it gives the same issue, it is something to do with graphics card. You may try to disconnect the monitor from the computer, it will show a message, if the message also is split then its a monitor issue.

Split screen


the word split-screen usually applies to microsoft office products. Click on Windows > Split on microsoft excel. Other than that, if you are referring to actually splitting the desktop. So you can have two desktops, then use VMWARE.... try googling it. It can manage multiple desktops.

Monitor screen picture is stretched out wide, and short verticle

If this is an incorrect display setting on the Operating system right click your desktop, choose properties then click settings under screen resolution bring the slider all the way to the left, choose apply. This will lower your resolution temporarily, if the picture fills the screen appropriately, we now know this is a software issue. The next step is simply to find the resolution you like the best. IF this does not resolve the problem, it is most likely a monitor problem. On your monitor there should be button allowing you to access the "reset to defaults" option. If you're unable to find the menu option let me know what make and model monitor you have. If you are able to reset to defaults and the picture is still bad, it's time for a new monitor.
