Resolution more than physical?

[Andrew V. Zachinyaev]

I have an iMac with a screen resolution of 2560*1440.
On VM (Windovs 8.1) on PD 10 in full-screen mode the maximum available resolution - 2560 * 1600. That is strange.
The problem arose after the changed global mode of VM from 3D-Games to Office and back.
Reinstall Parallels Tools does not help.

Hi Andrew, Please follow the steps suggested below to resolve the issue.
1. Uninstall Parallels Desktop 10 using PD uninstaller as suggested at http://kb.parallels.com/en/122653
2. Download latest build (28956) from: www.parallels.com/directdownload/pd10
3. Install it as suggested at http://kb.parallels.com/en/122647 (Note: un installing and re installing Parallels Desktop will not effect your Virtual Machine)
4. Install Parallels Tools manually as suggested at http://kb.parallels.com/en/112609 and check if the issue still persisting.
If the issue still persisting, please follow the steps outlined in http://kb.parallels.com/119926 to check the issue with Windows 8.1 resolution.

Hi,
Steps 1-4 did not help.
http://kb.parallels.com/119926 has note "Important: Not applicable for Windows 8.1 virtual machines. See KB 118587 for more details."
And my symptoms not "fonts are too small in Windows".
http://kb.parallels.com/118587 called:
Broken screen resolution in Windows 8.1 virtual machine on Retina display after the latest update of Parallels Desktop 9

But my iMac does not have a Retina-display ...
