Question about Samsung Techsan LM1770A 17" Monitor

Open Question

How do I fix my monitor when Windows open too large?

I have a Techsan LM1770A. How do I change the size of a window that opens too large to see the full screen? I have to scroll left and right just to read the news. I know very little about hardware. Computer is used. I am apparently using default monitor settings from my Dell piece of crap. Are there drivers for monitors (which I don't have)? If so, where can I get them?

I purchased my Acer monitor only a few months ago. I opened a very large file (pdf) of artwork for new label hung up my computer due to the large size. However since then my monitor is a...

When you start your computer, if before Windows starts up it's a shade of green, it could be as a result of the screen cable not plugged in properly at some point. If not or if that doesn't work, it could be the software or hardware but I don't know how a pdf can do that??

You can buy a regular power cord at the store such as wal-mart, staples, bestbuys. Most monitors have a standard power cable, similar to that of the computers.

Monitor is enlarged, wont return to normal size

You may have hit the "F11" key which takes the open window to fullscreen. "F11" toggles large, small... If not that, beboot. If that doesn't clear it up, then the display settings have gotten altered. Right click on the desktop, select "settings" and increase the resolution. Windows should prompt you to keep or reject the change. Select yes or no when prompted.

My HP monitor (f50) has malfunctioned

Try these 2 steps if they don't work get back to me :)

Step 1. Connect the video cable and turn on the computer. What happens?
  • If the monitor screen remains blank (no startup screens or onscreen display messages), the monitor must be connected to another computer using a different cable to determine if the monitor is bad. Skip to the Step to connect the monitor to another computer.
  • If the monitor is capable of displaying boot screens but is unable to display Windows, use the following steps to set the computer to a compatible resolution:
    NOTE: Find the native display resolution for your monitor in the User Manual or in the product specifications for the monitor model. If you are unable to find the native display resolution for your monitor model, temporarily use 1024x768 for troubleshooting purposes.
    1. Turn on the computer and press the F8 key repeatedly when the first startup screen appears.
    2. If you are using Windows Vista, select Enable low resolution video (640 x 480) , press Enter , and wait until Windows opens. To set display settings that match the monitor, use the steps in the HP support document, Changing Display Settings, Background Image, and Screen Saver in Windows Vista . If you are using Windows XP, select Enable VGA Mode , press Enter , and wait until Windows opens. Continue using these steps to set display resolution. If you are using Windows 98 or ME, select Safe Mode and perform the following steps to enter into a standard VGA mode:
      1. Once Windows opens to the desktop in Safe Mode, click Start , and Run .
      2. In the Open field type msconfig and press Enter . The MS Configuration Utility window appears.
      3. Click the Advanced button, and select VGA 640 x 480 x 16 if it is available.
      4. Click OK and restart the computer.
      5. After Windows opens, click Start , and then click Run .
      6. In the Open field type msconfig and press Enter .
      7. Click the Advanced button, and remove the checkmark next to VGA 640 x 480 x 16 .
      8. Click OK . Do NOT restart the computer.
    3. After Windows opens, right-click on an open area of the desktop and select Properties (Windows XP, 98/Me) or Personalize (Windows Vista).
    4. In Windows Vista, Scroll down and click Display Properties . In Windows XP, 98, or Me, click the Settings tab.
    5. In Windows Vista, select the native display resolution size using the Resolution slider. Set Colors to Highest (32 bit) . In Windows XP, select the native display resolution size using the Screen resolution slider. Set Color Quality to Highest (32 bit) . In Windows 98 or Me, select the native display resolution size using the Screen Area slider. Set Colors to True Color .
    6. Click Apply after you have made your adjustment. The screen should blank out temporarily and come back.
    7. If you are satisfied with the new display settings, click Yes on the Monitor Settings windows. If you are not satisfied or if the screen just goes black, wait: Windows sets the screen back to the way it was before. Try another setting until you find a display configuration that is compatible with the monitor and meets your needs.
      NOTE: If the native resolution is not available, download and install updated video driver software for your computer. Updating the video driver software can add more resolutions (graphics modes).
    8. Restart the computer. The monitor should now display a full screen image in high quality. You are done.
Step 2: Connect to another monitor
Using a different cable, connect the monitor to another computer that has video. Turn on the monitor and the newly connected computer. What happens?
  • If the monitor works, the video hardware on the original computer is likely to be the source of the problems. You can try connecting the original computer to another monitor that works to update its video drivers.
  • If the monitor remains blank, repair or replace the monitor.

Input not supported

Do you get anything on the screen when you first turn on your computer?

If you do the windows resolution somehow got set to high for the screen to handle. To fix this press the F8 key a couple times after the BIOS splash screen goes away ( The screen that has HP or DELL, etc on it). If done at the right time it will bring you to a menu that has several options including safe mode. You'll want to pick " Enable VGA mode." From there it will start to load Windows, but everything on the screen will be large. Once windows is fully loaded find a empty spot on your desktop and right click. From the menu that pops up please select Properties. It will open up a box that says "Display Properties." Click the tab that says Settings. On this tab move the resolution slider to right right a click or two to make the monitor normal size and click apply.

Most probably the Power Supply, generally is in these things... perhaps the Electrolytic Capacitors have Dried out and gone bad and need to be replaced, often all I do is replace every large Electro on the Power Board, (Often with much higer Temperature and spec Caps) and that "Fixes" it..
