Question about Likom Futura LD7 17" CRT Monitor

Likom Futura LDF770

I recently received a LDF770 flat screen. after finally getting the refresh and resolution set in linix I reset my computer and after the bios screen I got a monitor out of range message and the screen went black. After a little fiddling I noticed that the monitor had reset to a really low default (65 i believe) instead of 78. The problem is I cant figure out how to change this back and how to prevent this from happening again. Any help would be appreciated.

There may wrong setting of refresh rate. Most monitors work at 60 to 70 Hz refresh rate. Above that they tunned blank screen or out 0f range message displayed. Also check the output video signal. Please confirm technical specifications from the documentatation of the monitor.

Get this flsh out of my monitor.

Hi there.

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.

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 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 (Same for Windows 7)
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/AMD Home Page.
Check for Intel video support and downloads, Intel Downloads. (If you have an Intel mainboard and are using onboard graphics).

NOTE: If you are using onboard graphics with a mainboard that is not manufactured by Intel, just give me the name and model number of your mainboard and I can try and locate the graphics drivers for you.

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, then this means that the graphics adapter hardware on the first computer is damaged or might need to be upgraded to use the monitor. On the bright side at least it's not your monitor.

If however the flicker remains then the problem lies within the hardware 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 purchase 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.

Monitor's resolution need to be increased, how?


You don't say which operating system you are using.

The monitor resolves images across a fixed range of resolutions and resfresh rates.

It is the resolution of the graphics card or graphics adapter that can be changed, not that of the monitor.

Right click on empty space on your desktop > properties > settings.

Left click and hold on the slider and slide to the right in stages.

Each resolution change offers you a test page to accept or reject.

When satisfied Apply > Yes > Ok.

To reset the Refresh Rate:

Properties > settings > Advanced > Refresh Rate.

Then restart your computer.

Be careful not to exceed the resolution/refresh rate range of your monitor (1280 x 1024) / 75.0 Hz because if you do, when you restart the computer, the monitor will be unable to resolve the image and you will get a blank screen and/or an Out Of Range error message.

An out of range problem might only be resolved by using a different monitor to reset the resolution back to within the range of the preferred monitor.

Hope this helps

Screen flashes on and off for a while and then finally works for a while. Usually if it has not been used for a while.

Hi southernpg,

I see that you mentioned you screen flashes ON and OFF then finally works if not used for a while.

>Try changing the screens refresh rate, I see you have a 19" Flat Panel LCD, set the Refresh rate to 59hz if it set to 60Hz or above.

>Also try chanigin you resolution maybe a lower resolution if you have it set to the highest, or if you have it set to the lowest try setting it to at least a higher resolution possibly 1280x 780 for a 19 inch.

>Also try to see if there anre any lose cable from the LCD to the computer try reseating those cables just to make sure that everything is connected properly.

this should help you with your concern.

Have a nice day,

FPD1960 TFT LCD Monitor that turns on and you see the Windows Screen, and then goes black. Each time I turn it off and then back on, it repeats this pattern. All cables are securely fastened, I am using...

Windows is using a video mode the LCD monitor can't display. The cable doesn't matter in this case. It's an issue of the refresh rate and the resolution set in the system.

When the system boots, hit F8 just before the Windows splash screen would come up. Start the computer in safe mode with networking support. It should be able to come up in safe mode because the resolution will go to 640x480 or 800x600 by default.

Once you get to the desktop, go under the desktop properties. Hit Advanced. then go under the monitor tab. Make sure the monitor is defined. If it says generic display it will give you resolutions and refresh rates you can't use. If it isn't defined, you can install the driver under properties.

Finally, set the default resolution to something easy like 800x600 and try the refresh around 60-65hrz.

My 14" Likom monitor goes blank after installing WIndows XP

I assume your Samsung Magic CGB5607L is CRT monitor (Not LCD).
It could be the problem with "Refresh Rate" the monitor can't handle. Set the lowest resolution with lowest refresh rate. (800x600 @ 60 Hertz). in Display Properties
