HD 530 slow UI in windows 10

[KDang4]

Please help me identify the issue with slow and laggy windows 10 UI. All animations are choppy.

I'm using Dell XPS 15 9550 that has the followings specs:

Core i7 6700HQ

16GB DDR4 RAM

4K screen @ 60hz

HD 530 set to high performance mode running latest driver provided by Intel. build number: 21.20.16.4627

I also update the dell with the latest bios and windows are perfectly up-to-date

Is it because the 4K screen is too much for the HD 530?

Hello larrabee,

Thank you for contacting the Intel community. The processor can support 4k resolution so the resolution for the processor should not be a problem. You can see the processor supported resolution here:http://ark.intel.com/products/88967/Intel-Core-i7-6700HQ-Processor-6M-Cache-up-to-3_50-GHz http://ark.intel.com/products/88967/Intel-Core-i7-6700HQ-Processor-6M-Cache-up-to-3_50-GHz Do you get this same problem if you install the Dell driver? You should be able to download it here:http://www.dell.com/support/home/us/en/04/product-support/product/xps-15-9550-laptop/drivers http://www.dell.com/support/home/us/en/04/product-support/product/xps-15-9550-laptop/drivers Is this issue with an external TV/Monitor? If so, how do you have the external display connected? Is it connected through HDMI or are you using any adapters? Have you tried with different cables? Please provide us with a description of your system set up. Please let me know. Best regards, Ivan.

Hi Ivan:

Thank you for the reply. The issue happens with the built-in display of the laptop running at 4K resolution. When I change the resolution to 1080p, it's buttery smooth but when I run it at 4K , all animations are choppy.

The latest Dell driver 21.20.16.4590 is unstable and the driver will stop working after a while then get reloaded, sometimes resulting in blue screen. The animation still slow and choppy compare to other machine. Latest driver from Intel solves the blue screen problem.

Thank you for the information larrabee, being that the case, and since you are using an Intel® generic driver now, I suggest you to try the following:

Uninstall the driver you have now installed, please checkhttp://www.intel.com/content/www/us/en/support/graphics-drivers/000005598.html Uninstalling the Intel® Graphics Driver and Intel® Display HDMI/Audio Driver and after you uninstalled the driver do not restart your system and disconnect the internet; this is to avoid Microsoft to push any driver update. Once that is done, you can install the latest Intel® graphics driver manually, please see here how to http://www.intel.com/content/www/us/en/support/graphics-drivers/000005629.html Manually Install an Intel® Graphics Driver in Windows® 10 and Windows 8*/8.1* If this does not work, I know that soon a new driver will be released and we can try that as well, also you can contact your computer manufacturer for them to do a lab with this specific system you have so they can validate if this is actually an issue or if there is a defective component with your system. I hope this can help. Best regards, Ivan.

Thanks for the instruction. I've already installed the latest driver from Intel.

I will sit tight and wait for new driver. This has been an on going issue with Dell XPS 15 series using HD 530

You are more than welcome and I will appreciate your patience on waiting for a new driver, hopefully it will be released soon.

Best wishes, Ivan.
