What are the display settings for the zoom for the OS setting?
I am asking as it was witnessed early on in windows 8 and is really an issue in windows 10, where if the display zoom setting is greater than 100% the graphics display messes with the way it portrays the client GUI on the display screens for HP ALM. It is recommended by HP to set the display zoom no higher than 100%, but it depends on systems if they can go more. I have seen 125% and 150% settings that were unaffected but nothing greater than that ever has displayed correctly, 100% always displays correctly but some may find it a tad too small, unfortunately they can only play with the settings and see what works best on their individual systems.
Once you change that setting in the OS configurations you will need to restart your system to get the settings to take effect as just changing them in the Control Panel doesn't dynamically update them, the system must be restarted for the new settings to be applied.
Hope this helps,
