For now the HIGHDPI nuisance can be avoided by startig vvvv / a patch via batch file containing the following line:
reg delete "HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /va /f

it’s fine, i have a device now which i tested the flipEx thing on…
but indeed i didn’t just test with /dx9ex and swapeffect discard which i can confirm to work now.
so if we forget flipEx and just say win>8 needs /dx9ex for going fullscreen… would there be anything left with renderer problems?
(the fact that there is only discard available when AA is used is a dx9 limitation.)
Nothing I know of other than AsDesktop not working as advertised.
I thought so, only wanted to state all my observations because I assumed you had no device to test on.
concerning AsDesktop: does the AsDesktop TTY message also report 1024x786? and do you have your native resolution in the dropdown list of the renderer?
When setting AsDesktop TTY reports 1440 * 900 which is half of the native resolution. This relates to the display scaling setting (200%) - when the scaling is set to 150% TTY reports 1920 * 1200. But Actual Backbuffer Width / Actual Backbuffer Height output 1024*768 in fullscreen. The native res is in the dropdown and works.
edit:
Ok 1440900 is not supported so it defaults to 1024768. When using 150%/19201200 it “works” since 19201200 is supported. Still it should be 2880*1800.
alright, thanks. that should be easy to fix. i’ll have a look whether delphi can extract the DPI scaling percentage and correct the readings.
ok, wasn’t that complicated. please check AsDesktop again with alpha 24c175d6ae or later…
@tf latest available alpha was built January 4th.

AsDesktop now works as expected.
Unfortunately I found another one:
When dragging the renderer to a second screen it stops working in windowed mode. No exception, nothing in TTY (other than AsDesktop resolution change). When going fullscreen it starts rendering again, also when bringing it back to the primary display.
After setting Windowed Swap Effect to overlay part of the content is shown but scaled and “not moving with the renderer window”.
@bjoern: i can’t reproduce the last issue you described - tried with beta31.2 and latest alpha build (x86 and x64). moving the renderer window from one screen to the other and back works. what did i miss?
I tried with vvvv_45alpha31.5_x86 (24c175d6ae).

your patch works just fine, regardless of the used vvvv version or whether i use the dx9ex switch or not.
running on win 8.1 pro, geforce gtx 285 (driver version 331.65).
two screens, one 1920x1200 the other 1920x1080.
i hereby declare vvvv dpiAware.
please check with latest alpha and report. there may be some off pixels left but basically everything should now stay in place even if you choose other than 100% scaling via
Control Panel\All Control Panel Items\Display
EDIT: please start a new thread in the alpha forum if reporting regarding this.
now that vvvv is quite aware of windows’ dpi-setting and we set /dx9ex by default all of the issues in this thread should be addressed by the latest alpha build.
@bjoern: i tried the “renderer on second monitor” issue on another machine and also cannot reproduce it. this was on win8.1.
so please consider this thread closed and start new threads in the alpha forum for now if you still see anything bugging.
