Tip

Flickering LCD/CRT monitor screen or unstable image fix


If the screen flickers, make sure the display settings in Windows match the native resolution and refresh rate for the monitor. You can find the native resolution of a flat panel display in the specifications, in the printed material or on the box that came with the monitor. Some common native resolutions are 800 x 600, 1024 x 768, 1920 x 1080, and 1680 x 1050. To find out more about optimal screen resolutions see my tip on resolutions here.

The most common refresh rate for LCD monitors is 60 Hz. This normally cannot be changed for flat panel displays using Plug and Play settings. However, if you are using special video software to increase or decrease the refresh rate, change the refresh rate to match the default refresh rate specification of the monitor. To find out more about refresh rates see my tip here.

STEP 1
To change the screen resolution and refresh rate settings in Windows, do the following:
- In Windows XP
See my tip on setting up the optimum screen resolution for Windows XP here.

- In Windows Vista
1. Click Start, and then click Control Panel .
2. Find the Appearance and Personalization area, and click Adjust Screen Resolution .
3. Move the slider bar until the screen resolution matches the native resolution.
4. Click Advanced settings, and then click the Monitor tab.
5. Select the Screen refresh rate that matches the default rate for your monitor (if it is not already selected).
6. Click OK, and then click OK again.

If you cannot select the native resolution or the native resolution is unavailable, continue to the next step to update the drivers for the graphics adapter on the computer.

You can get the latest updated video drivers from the video hardware manufacturer's Web site. Here is a list showing some of the video hardware websites:

Check for NVIDIA video driver updates at NVIDIA Home Page.
Check for ATI/AMD video driver updates at ATI Home Page.
Check for Intel video support and downloads, Intel Downloads.

After updating the video drivers, go back to Step 1 and try to change the screen resolution again.
Note: If you cannot select the native resolution after updating the video drivers, the graphics adapter in the computer might not support that resolution and may need to be upgraded.

If after changing the resolution and updating video drivers the flickering persists then check the video cable connections. Unplug the cable and inspect the cable for damage. If the cable is damaged, replace it with a new cable. Try to use cables less than 3 meters (10 feet) long.

Monitors are sensitive to magnetic fields so have a look at the environment around the monitor. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause flickering. Temporarily move electrical items away from the monitor to see if they is producing a field that causes the flicker.

If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.

To see if the video coming from the computer is causing the problem, temporarily connect the monitor to another computer. If the flicker is gone when the monitor is connected to another computer, the graphics adapter hardware on the first computer might need to be upgraded to use the monitor.

If however the flicker remains then the problem lies within the harware of the monitor itself and is not a software problem. If you have bought this monitor fairly recently then I suggest you take it back to the place of purchace and have them test it. Some monitors carry 3 year warranty support so if you bought it within the warranty period specified by the reseller I suggest you see if you can get refunded or have them swop it out.

How do i get my computer out of the resolution mode?


Apparently the monitor screen resolution setting is not correct. Screen resolution stays up until it is corrected.

Either the setting is off in Windows, or you have been changing the monitor settings, with the monitor.

WinXP:

Right-click on an empty area of your desktop screen.
Left-click on Properties at the bottom of the list.
Left-click on the Settings tab.
Go down to where it states Screen Resolution.

What is the pixel setting? For example mine states 1600 x 900 pixels.
I am running dual monitors, and this is the correct screen resolution for the Primary monitor.

If it wasn't I would Left-click on the Slider, hold the left mouse button down, and slide the Slider to the correct native resolution.

(Under Screen Resolution is a line. To the left it states - Less
To the right of the line it states - More
The Slider is the rectangular down arrow on the line )

ALSO;
Under the Color quality heading, make sure in the box under it, that it states - Highest (32 bit)
IF not, left-click on the blue down arrow to the right.
Then left-click right on - Highest (32 bit)

How to know what is the native resolution for your monitor?
Look at the manufacturer name, and the model number on the back.
Type this information in your browser search bar, then click on the search icon.

Look for Specifications.

If you changed the screen resolution settings with the monitor, press the Menu button. The screen should go off.

ALSO, with a new monitor there is an Installation CD Disk, provided with it.
This disk MUST be used. It has the drivers for the monitor on it.

[ Drivers: Small pieces of software that allow the Operating System to 'communicate' with a device.

The monitor is a Device.
Windows XP, and Windows 7 are two examples of an O/S.
Operating System ]

If you have Vista or Windows 7, post in a Comment.
For additional questions please post in a Comment.

I have knocked a button on my laptop the screen has gone small i can not make it bigger i have been into properties but dont know where to go next


Position your Mouse on your Desktop. Just on the background. Right click. Select Properties. Select the 'Settings' Tab. You can select the resolution of "800 x 600" for larger icons or if you want more desktop area move to the right. I am set to "1400 x900"

The other setting you should look for is the Color Quality. Generally this should be largest number. IE 32 bit.
