           Summary: Provide a way to enlarge the visual appearance of the
                    hole workspace and the applications
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: sommerluk at gmail.com


Version:           unspecified (using Devel) 
OS:                unspecified

Use case:

You want to use KDE on your plasma television which is quite big (let's say 42
inch) and has a high resolution (let's say 1920x1080). You want to sit quite a
distance away (let's say 6 meters).



Reproducible: Always


Actual Results:  
With the given resolution it is impossible to read the text and recognize the
icons at the given distance.

Expected Results:  
There is an option in the system preferences that lets you set something like a
representation factor. So you can put this to 2,0 or 2,5 and you see everything
bigger.

This issue is about to display the applications and the workspace at a higher
resolution. It's not about using applications like a magnifying glass. It's
about the possibility that the applications work themself at a higher
resolution.

I know that it is yet possible to reach a big part of what I have described
here. For example you can change the font sizes (unlimited), icon sizes
(limited!), the width of the scroll bars (only for Oxygen widget style,
limited), the curser size (only hardcoded sizes available), the window
decoration margin (only for Oxygen window decoration, only some predefined
values).

However, there are elements which size can't be changed. For example checkboxes
and radiobuttons in the widget style. Or the icon size of the applications in
the system tray. Or the size of the icons that are displayed for plasmoids to
resize them or set their preferences or to rotate them. And often the margins
that are used in QLayout are fixed. So the overall impression isn't good at
all.

We use non-standard display sizes more and more. So it is importand that KDE
supports this usage better than it currently does. It should be easy to specify
a factor, so that everything is simply displayed bigger, with the same overall
impression. This factor should not be phased, but continiously variable.

I know that this will require work in many different areas of KDE, but I think
it is important to have this in mind for further development.
