Lumia 640- display issue: constantly fluctuating display

HI.

I just purchased a new lumia 640. I was exploring the options and came across something weird with the display.

The display brightness keeps on fluctuating in intensity by itself.

Few observations:

This is much evident when the Settings>brightness is set to automatic and Settings>display>brightness profile>adjust>Brightness bar is set to lowest (slider on the left side).

If I increase this brightness bar to maximum the problem resolves.

Also if I select a brightness level in Settings>Brightness as low, medium or high (and NOT automatic) the problem is resolved as long as the brightness bar in brightness profile is not lowest.

The problem is most evident against a white display like browsing on IE.



So the problem is: if I reduce the brightness to it's lowest level using all settings then the display fluctuates.

 

No brightness control bar is display settings

I had moved my desktop computer into my bedroom 3 months prior to the start of trying to fix the issue with the brightness control bar not showing up on February 23, 2018. I had never checked to see if the brightness control bar was in the settings because
I didn't want to change the brightness at the time. I decided to change the brightness on February 23, 2018, and noticed it wasn't there. That is when I got in contact with Microsoft community and placed my concerns and questions on how to get the brightness
bar back.

I'm all up to date on Windows Update for its drivers as well as the graphics display manufacturer drivers. No drivers are missing.

 

Hi, I don't know what a 'brightness bar' is, I'm afraid- perhaps you could explain how you normally make that appear?

Would you be interested in being able to control the brightness by, e.g, holding down the CTRL key and the scroll button on your mouse? This (and volume too) can be done with a small freeware program called Volumouse.

You can choose key combinations to do this to suit yourself.

 

there should be a brightness bar in settings - system - display under orientation to adjust the brightness. vut mine does not have this option. *Sad

 

The one here?

Could you post a screenshot of what you're seeing.. the entire window?

Open Device Manager, check there are no yellow triangles.
Some suggest uninstalling the monitor resolves this:
Microsoft Community

Do you see one here (in the Control Panel)?

 

It seems that your AMD Radeon 7700 driver in Windows 10 does not have that capability. You can try searching for another driver to see if that has control over brightness - there is some guidance in Where to get hardware drivers. If AMD still produce drivers for this graphics card then you will probably be able to solve the problem but if not then it is just pot luck.

This situation is not uncommon in Windows 10. I have seen online posts by others in the same situation. I upgraded a 6 year old Windows 7 computer & an 11 year old XP computer to Windows 10 and the newer one has brightness adjustment whilst the older one does not.

Despite the lack of a brightness adjustment in the expected place, you might find that any keyboard shortcut that worked in your previous OS [such as a function key] still works.

@David1959 - have you previously had this brightness slider available using this PC- if so, what's changed since then?

If an older version of your graphics driver helps, that's possible, if you know it will, otherwise I'd commend my idea using freeware to you- you don't have to click several things to find the slider- just the mouse or a key and the mouse wheel.

 

Thank all the brightness adjustment was working in win 7. thanks for the help. *Smile

 

also i'm using a HTMI tv as a monitor so it probably won't show. Thank again to all foe your suggestions and help. *Smile
