6349 cannot display


Try another monitor on the desktop. You problem is either the monitor or the video card. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the desktop. If the borrowed monitor shows the display and works ok, then your original monitor is bad. If the borrowed monitor does not show the display just like your original monitor did not show a display, then the Video Card in the computer is bad.

Th problem is lcd


No display on laptop's internal monitor, and there is no blinking cursor?
Start with seeing if it is a display problem.

Connect a VGA monitor to the laptop. If the display does not show on the external VGA monitor, the problem is the graphics chipset.

You did not state the model number of the Fujitsu laptop, therefore all I can give is generic basic information.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the laptop.
This is an example of a VGA Cable, and a VGA connector,

http://en.wikipedia.org/wiki/VGA_connector

The VGA connector (Port) on your laptop is either on the side, or back of the laptop. May be marked on laptop as RGB.

You can use a CRT type of VGA monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the display should show on the external VGA monitor.
If not there are at least 3 display options;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and at the same time tap once on the Display Toggle-Over key.

The Display Toggle-Over key is one of the F keys at the top of your keyboard. F1 through F12.
It will have a monitor symbol on it.
(For example most HP laptops use the F4 key )

No display on external VGA monitor? Hold the Fn key down again, and tap once more on the Display Toggle-Over key.

If no display shows on the external VGA monitor you have a bad graphics chipset. Motherboard replacement.

If a display does show on the external VGA monitor, you have a problem with the Video Cable, and/or in the Display Assembly.

Post back with the results, after using an external VGA monitor, in a Comment.

Regards,

No display everything turns on windows loads but no display


We can further isolate the issue by connecting an external monitor to the notebook. If the display is fine with the external monitor, this clearly indicates that the issue is related to the LCD screen. Otherwise, it is due to the some other internal hardware.

You may follow these steps to connect the notebook to an external monitor.

1. Turn Off Computer.
2. Connect the monitor cable from the monitor to the monitor port on
the rear of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

* Switching the display to the external monitor

Press FN + F4 to toggle the display between the Notebook display and
External monitor.

have you isolate the monitor very much? try to use other monitor. if other monitor shows some display then your old monitor is defective. replace a new one. but if the other monitor does not shows some display the your video card is defective. you have to purchase new video card.

Heat from monitor


The monitor,screen,adapter or display of a computer is the primary user interface. Monitor problems are some of the most common computer problems since the voltages inside a monitor can be as high as 10 KV. Many of the problems can be fixed yourself by simply changing the settings but in a few cases you may have to either replace or repair the monitor.
google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad); How to troubleshoot and fix computer monitor/display problems
1. The monitor/display flickers
Check the refresh rate. If the refresh rate is 50 Hz/ 60Hz (depending on which country you stay), it can be affected by interference from electrical power signals like those from fluorescent lamps . Increasing the refresh rate to 72Hz is recommended , since higher refresh rates reduce eyestrain and headaches
2. The display works fine initially, then after some time there are black lines on the screen and then the display disappears
There is a problem with the copper windings in the CRT monitor which are getting heated. It is better to replace the monitor
3. For a new monitor, you get a blank screen or distorted image.
Many monitors, especially LCD monitors, can only handle resolutions which are less than the native resolution, so set the resolution at the native resolution only. The native resolution of a LCD display is lower for smaller LCD screen sizes, typically 1024 X 768 for 15" LCD. CRT monitors have a better resolution than LCD displays
4. The display on the monitor is not steady
This is a result of power system interference from users of the power grid, particularly UPS, power tools and heavy machinery. Try changing the position of the monitor.

5. There is a shadow on the images on the display
Try reducing the contrast setting on your monitor.
6. Monitor becomes blank occasionally
Could be a problem with the display card, check with another monitor. The monitor display cord and power cable should be fixed properly and there should be no loose connection.
7. Dark Spots on the Screen.
Move speakers,USB modem and other magnetic devices away from the monitor.
8. Incorrect Colors - red may become dark brown, blue becomes purple.
Check your video cables and connectors for bent or broken pins and wires. Sometimes there may be a problem with your display card, which can be retuned using a software available with monitor technicians.
9. Run Antivirus to scan corrupt software files.Virus cause distorted characters and images.
10. Set your monitor/display pixels to the software requirements. some softwares require higher pixels to run or to be displayed. some media players, web applications, video games applications and photo editors/view softwares have option to view photos on low or high quality

Monitor


did some thing change your refresh rates in the display section of your settings for the monitors? also have you tried to hook up another computer to see if it will display on the monitor? if nothing displays on the monitor then the monitor is faulty. if another computer (even a laptop) can display on the monitor then the video is set to high for the monitor to understand it. to reset monitor refresh with out a screen that will work you need to get into safe mode and reset the display settings to 60 hz and only 800 x 600 for starters and increase them until you cannot get a signal. if you cannot do this then a service shop will be able to assist you

GIGABYTE X1300PRO GRAPHIC CARD


On many portable computers and some desktop computers (those with two video ports on one video card), you can expand your display to a second monitor by using Dualview. Dualview is very similar to the multiple monitor feature, with the exception that you cannot select the primary display. On a portable computer, the primary monitor is always the LCD display screen. On a desktop computer, it is the monitor attached to the first video out port.
Once you attach the second monitor and turn on your computer, use Display in Control Panel to configure your settings, just as you do with multiple monitors. Dualview can be used with docked or undocked portable computers

This procedure applies when two or more monitors are connected to one computer.
  1. Open Display in Control Panel.
  2. On the Settings tab, click Identify to display a large number on each of your monitors, showing which monitor corresponds with each icon.
  3. Click the monitor icons and drag them to positions that represent how you want to move items from one monitor to another, and then click OK or Apply to view changes.
Notes
  • To open Display, click Start, click Control Panel, and then double-click Display.
  • The icon positions determine how you move items from one monitor to another. For example, if you are using two monitors and you want to move items from one monitor to the other by dragging left and right, place the icons side by side. To move items between monitors by dragging up and down, place the icons one above the other. The icon positions do not have to correspond to the physical positions of the monitors. You can place the icons one above the other even though your monitors are side by side
