Dithering, color banding using HD Graphics 4000 on lenovo thinkpad t530

[BBob4]

Hi there,

[My problem]

Gradients look bad on my laptop. "Bad" as in "color banding", "very strong dithering", especially when subtle gradients are involved.

I use both the internal display and an external samsung SyncMaster T220, conncted with VGA. (The external Syncmaster did not show the error on my old laptop.)

[Details]

This happens systemwide, from desktop background to newly generated images in photoshop.

I already updated my graohics driver via windows hardware manager and rebooted.

I also executed the Lenovo Sytem Update tool, which updated my BIOS, and rebooted.

What are my options here?

[Setup]

graphics adapter = Intel(R) HD Graphics 4000

driver version = 10.18.10.3621

driver date = 17.05.2014

Windows 8.1. Pro 64 Bit

Lenovo Thinkpad T530

Thanks a lot for any advice!

Bob

Hello Bob, thanks a lot for posting your issue in Intel Communities.

I would recommend you to uninstall the latest graphic drivers and install the previous version 3496 just for testing purposes.
