I changed my monitor from 22´´ to 27´´ and enlarged the types to 150% in the general windows settings. Photoshop and other adobe programs does not take this settings, the taskbar has only very little types, drop-down menue is ok. Are there any settings to enlarge the types in the taskbar?
What is the resolution of the monitor? What OS are you using?
The resolution is 2560x1440 and I use windows 7
I think you are stuck with what you have got for the time being at least. There are apparently issues with Microsoft that making a similar provision for Windows, to what was done for Apple Retina displays, problematic. In fact it might not happen at all!
That res at 27 inch shouldn't be too bad though. We have posters here with 14 inch laptops with 3500 pixel wide screens. Now that would be difficult to use!
