UltraVNC

Supports XP or later
UltraVNC 1.3.8.0 distribution for 32-bit Windows XP or higher.

Really?

Thanks for updated encryptionplugins_1211.zip, Rudi!

Last x86 installer (from 22-05-2016) contains winvnc.exe on french (?) language.
DSM-plugins also outdated, from 2013 year (encryptionplugins_1211.zip - form 2014 year).

Thanks, ENU works fine, hextile works in auto mode for old servers.

1.2.0.6 - hextile for 16/32bit desktop
1.2.1.1 - hextile for 16bit desktop, u2 for 32bit desktop

Thanks, Rudi! Works fine, hextile @ 16bit!

New (1.2.0.9+) encoder auto-selection logic is very strange.
All viewer presets (slow/modem/medium/lan/ultra) are lossless (zrle/hextile/ultra).
But auto mode can select lossy (u2) encoder, u2 not included in presets. This is not logical.

You can set a higher jpeg quality to minimize lossy against size.

Yes, but even when jpeg q=9 compression artifacts appears.

I will check 16bit, it' more natural to fallback to hextile if u2 is disabled.
Yes, thanks! :D

But its better if user can also change auto-select logic selector (ini):
OLD (<= 1.0.2.6) - ZRLE / hextile (16/32-bit)
NEW (> 1.0.2.6) - ZRLE / (u2 if 32-bit / hextile if 16-bit)

I don't like u2 ...

It seems that u2 encoding not supports 16-bit screen color depth on server side (XP 32-bit). Is it right?
When color depth = 32-bit -> u2 works fine (auto and manual)
When color depth = 16-bit -> u2 falls to ZRLE (auto and manual)

network/cpu server/cpu viewer
Client - Phenom2 1100T (6 cores 6 threads 3800 Mhz)
Server - Atom N2600 (2 cores 4 threads 1600 Mhz)
Network - Ethernet 100 mbps
Not enough for u2/Hextile? :|

Normal , if your viewer support ultra2 encodings it is used from 20.000 to 256
if not zrle is used when ...

Why new versions 1.2.0.9-1.2.1.1rc3 always auto-selects ZRLE and never Hextile for high-speed local connections (100 mbps)?
1.2.0.1-1.2.0.6 -> auto-selects to Hextile
1.2.0.9-1.2.1.1rc3 -> auto-selects to ZRLE
