Screen flickers when showing grey gradient

[Daidojih]

Hey guys,

Any of you having a screen flickering problem when displaying grey?
Here is a link to someone with a similar problem (and an example image).

On the W510 do you know if there is a simple solution to this problem?

Thanks.

no one else having this problem?

Which display do you have on your W510? I could look on my T510 tonight for you, but I've got the HD+ 1600x900 screen so it may not be very helpful. Also I've got the integrated Intel gfx rather than your discreet gfx so yeah probably not helpful at all. Anyone else?

[Daidojih]

I got the HD+ screen as well

I'm not seeing it at all. It flickers a tiny bit when I drag it around the screen, but as soon as I stop and leave it in one place, it is stable and free of flicker. I wonder if it's something to do with the discrete graphics adapter on the W510?

On a releated note: I did notice some backlighting uniformity issues when dragging the image around. The bottom half appears quite a bit lighter in colour when near the center of the screen, and darker when near the far left or right sides of the screen. On the other hand, if I set that image as my desktop wallpaper, tiled, and minimize all windows, I can't really see the backlighting uniformity issue. So it could be some weird alpha-blending issue, perhaps?

Now that you mentioned it, I downloaded the image and opened it with windows live photo gallery. There is less but still noticeable flickering when compared side-by-side with the image loaded in Firefox 3.6.

I do not notice the uniformity issues when moving the image around.

When the image is set as the wallpaper (tiled) my screen is going crazy with the amount of flickering happening!

It's just the bad quality screens Lenovo uses unfortunately ...

If that were the case, I think I'd be seeing it also, since we have the same screen (As far as I know--unless there's a different HD+ panel in the W510 than the T510). I'm thinking the difference is in the graphics adapter--mine's got the on-die Intel integrated graphics and the OP has the discrete adapter that comes with the W510. It could also be a driver issue--have you made sure you've updated to the latest?

[Daidojih]

Yup. Updated to the latest driver
