Tip & How-To about Philips 190B6CB/27 19" LCD

Screen goes blank after POST

If this problem occurs, it's usually after a monitor upgrade from CRT to LCD.

You're booting your computer, everything looks fine. The POST completes, Windows is starting up, then... Black screen.

You know both the card and monitor worked during the POST, so they must be functioning. So what changed?

Chances are the 'Refresh Rate' is set too high for the replacement monitor.

Put the old monitor back on and reboot.

  • Right Click the Desktop
  • Click Properties
  • Click Settings
  • Click Advanced
  • Click Monitor
  • Lower the refresh rate or set at optimal
  • Check the box 'Hide refresh rates this monitor can't display'
Shutdown, Switch back and try it now.

Good luck

After upgrading from Vista Home Premium 32 to Windows 7 Home Premium 32 I have terrible blurry text and get headaches. My display is a Vizio HDTV 20'' and I have NVIDIA GeForce 8500 GT display adapter. Have tried changing desktop size, resolution, turned off ClearType. Tried different themes. Nothing seems to make a difference. This is just about unusable. All was fine prior to the upgrade. Is there a solution? Would it have made a difference if I had done a Custom install instead of an Upgrade?


the problem is because the VGA driver has not been installed. The VGA driver for Vista is different from that of Win 7. Running the upgrade also could cause the problem.

Back up all your important files, and re-run the win 7 afresh. You have to re-run by inserting the win 7 cd into your Cd drive, restart your system and allow it boot from CD and not running from windows.

In the process of the installation, format your hard drive and allow the installation to complete.

After then, install the drivers like; Sound, vga, etc and do windows update. After the windows update, your display will be unique.

Take care.

I was adjusting picture on monitor and now picture completely messed up

  • Signal out of Range.
  • Out Of Scan Range
  • Horizontal frequency is out of range.
  • Cannot Display This Video Mode Out of Sync

This issue may occur if the signal from the video adapter exceeds the scan range of the monitor. The video adapter setting for updating the screen (the refresh rate) is incompatible with the monitor.
you should reinstall your video drivers in safe mode.

To restart in safe mode repeatedly press the F8 key during the computer startup. This will bring a menu where you'll be able to choose safe mode.
