When you install a video driver it talks to the lcd screen via signal to the graphics chip set it tells it what resolutions it is capable of at what hz, or screen refresh rates. Or go into safe mode and remove the video driver and let window reboot with the laptop screen enabled.

If it at least shows a boot when powered on it`s the case.Īll you have to do with another monitor is set the resolution lower. So the prior settings of the old screen are wrong, but still stored in the windows resolution table. The resolution and display Hz may differ with the new screen. What I am saying is if the last resolution in the laptop was set at 1600x1050 at 75 hz the screen would be black when loading into windows on the laptop screen. In the subsequent window, first, click on 'Change settings that are currently unavailable' ( near the top of the Window ) and then remove the checkmark from the box against 'Turn on fast start-up (recommended)'. Simply because at set resolutions the Hz range can be different. Select Power and sleep, then click on Additional power settings - in the following window, click on 'Choose what the power button does' in the left-hand pane. Often the mistake is thinking that a screen of the same size can be used.Īnd if you check if it is lcd back lit, or uses a cold cathode white light array.īut the internal decode chip on the screen matters, in some cases. I hope that when you fitted the new screen you got the details off the back of the old one.
