display problems

[bhaskarjyoti]

I have a lenovo z460 laptop. Recently i have been facing problems with my display. My (LED) display is flickering excessively right from the first boot screen.I face the problem even in the bios screen. I recently updated my bios from v2.08 to v2.15. The problem started a few days after that. Is that causing the problem.

Hi

Welcome To Lenovo Community

Please check & Confirm if the system is flickering on battery mode

Or only when adaptor is connected   or in both modes

Hope This Helps

Cheers!!!

The problem arises both in the battery mode and ac mode.

Hi

Since you are facing issues on both modes , i would suggest that you should visit the nearest service center

to get the bios downgraded to verify if issue is resolved

Hope This Helps

Cheers!!!

I have myself downgraded the bios to its original edition at my home but it did not solve the problem.

Hi,

Correct monitor flicker (refresh rate)

Flicker can be a problem on CRT monitors. LCD monitors (also called flat-panel displays) don't create flicker.

A flickering CRT monitor can contribute to eyestrain and headaches. You can reduce or eliminate flicker by increasing the screen refresh rate. A refresh rate of at least 75 hertz generally produces less flicker. (Because LCD monitors don't create flicker, they don't need to be set at high refresh rates.) For more information about choosing the best refresh rate for your monitor, see Getting the best display on your monitor.

To correct flicker:

1. Click to open Screen Resolution.

2. Click Advanced settings.

3. Click the Monitor tab, and then, under Screen refresh rate, click the screen refresh rate you want. The monitor will take a moment to adjust. If you want to keep the changes, click Apply. If you don't apply the changes within 15 seconds, the refresh rate will revert back to your original setting.

   Notes

   • If you notice flicker on a CRT monitor, you might need to change your screen resolution before changing the refresh rate. The higher the resolution, the higher your refresh rate should be—but not every screen resolution is compatible with every refresh rate. For more information, see Change screen resolution.

   • Changes to the refresh rate affect all users who log on to the computer.
