Windows can not manage to have different DPI 1080p and 4K monitor

Windows can not manage to have different DPI 1080p and 4K screen. However, it is impossible not to have a magnification of 1080p but 25-35% on Dell 4K (P2715Q) intimidate. Windows 8.1 increases on both screens. I have clicked out that it will not change on both screens, and only on 4K Dell P2715Q.

I have Nvidia GTX 680 and latest drivers 347.88! Windows is 8.1 Pro with Mediacenter.

Hi

Regarding to your issue, since Windows only provide basic display drivers, resolution and DPI control are supposed to be supported by your Video card and driver. Check with video card manufacturers about resolution/DPI parameter supported by your video card. Then compare to multiple monitor settings. This problem might occurs due to performance of Video card. Since we are not expert on NVidia product, Id suggest that contact with NVidia. There you can get more effective suggestion by other experts who familiar with their products. Your understanding is highly appreciated.

Hi

Thanked for answers.

I have also updated the drivers form the NVIDIA to 350.12 but the problem persists.

What I read here on the forum and on the other forum/homepages, it's Windows 8.1 that cannot handle different scaling DPI at the same time, 1080p and 4K screen. It is simply not possible to have different scaling profiles simultaneously in Windows 8.1. Correct me if I'm wrong.

Sincerely

Hi,

Agree with you, quote from Windows 8.1 DPI Scaling Enhancements Windows blog.

here have been some questions about when per-display DPI scaling is used (different DPI scaling values per display) and I wanted to add a note here to clarify. On Windows 8.1 when you have the Let me choose one scaling level for all my displays check box checked (not checked by default) one uniform DPI scaling value is used for all displays.
