Dual monitors just won't work.

I simply cannot make VNC display two displays. Only get the primary. Tried reinstalling UVNC.

Windows 7 x64 Ultimate, UVNC 1.0.9.1.

It is installed. The only difference it makes is disabled Aero.

Well, I'll be damned. I had "secundary=1" there but "secondary=0". Why is secundary still there? And this was a fresh install of 1.0.9.1 and it's still secundary in "Edit settings" app.

Anyway, it helped. Finally! Freaking typos...

Thanks!

secundary=== was a typo in an older version
Doesn't exist anymore, but it could be in the ultravnc.ini as it is not erased on update.

When the mirror driver is enabled you can't have aero, it depend on video hardware, and a mirror driver is a software emulation.

I swear that was a fresh install, I manually removed the UltraVNC directory after uninstallation of 1.0.8.x. And I still see "secundary" in "Edit Settings" application. Maybe it IS still there?

I'm still having trouble with dual screen on ultravnc. Guess it's because secondary is offseted above primary... Anyway I'll run full tests for the occasions trying to help the developers here

My Server: UVNC 1095, WIN7 ULTIMATE / uVNC 1095 /
My Client: UVNC 1095, WINXP

Config for Test 1

Dual screen : primary 1680x1050 offset 0,0 ; secondary 1280x768 offset 210,-768

The uVNC Service is stopped and restarted between each experiment

Experiment 1 (default):
Primary = 1, Secondary = 0, driver OFF
Displays primary screen only
Inputs are ok
Image

Experiment 2 :
Primary = 1, Secondary = 0, driver on
Displays a 1680x1050 box with the secondary screen upper, and part of the primary screen below
Inputs are ok
Image

Experiment 3 :
Primary = 1, Secondary = 1, driver on
Displays a 1680x1818 box with secondary upper, primary below
Inputs are ok
Image

Experiment 4:
Primary = 1, Secondary = 1, driver OFF
Displays first (for a second) a 1680x1818 box with secondary upper, primary below
Displays then (until any input) the same 1680x1818 box but with Primary upper, copy of the primary below
When inputs are made, switch back to state 1 with many copyrect garbage
Image
Image
Image

Experiment 5:
Primary = 0, Secondary = 0, driver OFF
Same as EXPERIMENT 1
Image

Experiment 6:
Primary = 0, Secondary = 0, driver ON
Same as EXPERIMENT 2
Image

Experiment 7:
Primary = 0, Secondary = 1, driver ON
SAME AS EXPERIMENT 3
Image

Experiment 8:
Primary = 0, Secondary = 1, driver OFF
SAME AS EXPERIMENT 4
Image
Image


Config for Test 2

dual screen : primary 1680x1050 offset 0,0 ; secondary 1280x768 offset 210,1050 (secondary below primary)

Experiment 1 : After Changing secondary screen below primary
Primary = 1, Secondary = 0, driver OFF
Displays primary screen only
Inputs are ok

Experiment 2 : Activating driver in server options while connected with viewer
Viewer box is immediately resized 1680x1818
Primary screen upper, secondary below
Inputs are ok.

Experiment 3 : Disconnecting and Reconnecting viewer
Box is 1680x1050, displays only primary.
Inputs are OK.

Experiment 4 : Changing secondary display to offset 212,-768
Box remains 1680x1050, primary upper, part of secondary below
Inputs are OK.
Image

Experiment 5 : Disconnecting and Reconnecting viewer
Same as Experiment 4, or Test 1 / Experiment 2.

Experiment 6 : Changing secondary display to offset 1680,0
Box is immediately resized 2960x1050
Primary screen is on left, Secondary on right
Image

Experiment 7 : Disconnecting and Reconnecting viewer
Box is 1680x1050, only primary displayed
Inputs are OK
Image

Experiment 8 : Changing secondary display to offset -1280,0
Box remains 1680x1050, secondary is displayed on the left, part of primary is dislpayed on the right
Inputs are OK
Image

Experiment 9 : Disconnecting and Reconnecting viewer
Same as Experiment 8


Conclusion

If a user wants to display both primary and secondary displays :
- uVNC handles it well if driver is ON

If a user wants to display only primary screen
- uVNC handles it well if driver is OFF
- uVNC handles it well if driver is ON and secondary screen on the right of primary

If a user wants to display only secondary screen
- uVNC cannot handle it, driver ON or OFF


Thanks

This seems not to be true (or at least not in 1.0.9.6).

I was able to use a secondary monitor just by changing "ultravnc.ini" (replace "secondary=0" with "secondary=1"). There is one gotcha however - you need to scroll the view to the right to view the 2nd screen.
