You know how there is a sharpness setting for some monitors? My monitor, and old Acer H203 LCD, lacks this feature. I tried power strip software as well as soft MCCS software to no avail.
Is there any way to replicate/emulate this sharpening effect for the entire screen? It could be for Windows or Ubuntu. Even if it's for Mac, I would still be interested to look into the details.
It'd basically be like applying the Photoshop sharpen or unsharp mask setting, but in real time as an overlay to your entire desktop for any application.
