[1809, ou] Mad about DPI settings and extend mode

[Warwick_Tech]

Hi All,

 

MS have made my life difficult again.

 

So it seems when you connect to a big touchscreen on my network (on extend) the DPI% changes to seperate values on each screen, so one screen can be 100%, the other 125%

 

This isn't a problem until someone starts using the pen tool on the touchscreen and it doesn't match the powerpoint.

 

I've tried all the regular fixes, but no joy -

Or better yet does anyone know how to set the advanced DPI settings via GPO or registry?

 

 

The same thing does happen rarely on duplicate, but it's more consistent.

Ok, so progress;

 

The following registry entries always reset eveything back to 'recommended'

 

 

And the following GPO greys out the 'fix blurry apps' dialog box

But still no override for (recommended) display options

Surely the problem is the pen driver being out of date, what touch screen?

Hi Mav,

 

These are new boards, all up to date drivers;

 

Though after testing for an hour or so I think I've cracked it, I needed to put a '1' not a '0' in Win8DpiScaling as this is what 'forces' windows to the 100% (96dpi) setting and greys out the option to change it.

 

Hopefully it hasn't broken anything!

 

Thanks again,

I mean the manufacturer hasn't updated the driver to support different DPIs on different screens, which is much more common these days with 4k screens

Oh I see... It's been a long day!
