Just purchased an HP Envy Laptop. Windows 10. Intel HD 620. Color is really washed out. Went into the Intel Graphics Control Panel, and there is NO gamma slider. What happened to it and where do I find it???
I understand you are looking for the Gamma feature through the graphics control panel.
Please bear in mind that with Windows® 10, this feature is now part of the operating system.
