More Examples of Windows Multimedia Redirection

In my last entry, "CL" posted a comment wanting more to see more examples of Windows media redirection.  Here's another video showing a variety of clips.  Talking heads, animation,  a couple of VC-1 live streams.  Enjoy.  Still have the dog barking at the tripod problem, so I apologize for some of the shaky parts.  Take a Dramamine if you get queasy.  If you want to watch this in a bit better quality, follow this link and click on the "watch in high quality" link once you get into YouTube (right under the "Views" number).

Sun Rays as Multihead Windows Terminals

As a follow on to my last post regarding RDP resolution, I thought I'd post some pictures of various multihead configurations using Sun Rays and the Sun Ray Connector for Windows.  Note that these resolutions work for normal Windows Terminal Server sessions as well as Virtual Desktop Computing (VDC/VDI).

Here's a Sun Ray 2FS Driving dual 24.1" LCD's.  Resolution is 3840x1200

Here's a 3x1 multihead group using Sun Ray 270's. Resolution is 3840x1024

Finally here's a 4x1 multihead group using Sun Ray 270's. The individual Sun Rays were constrained to 1024x768 in order not to exceed the max resolution width of RDP which is 4096. Resolution is 4096x768

Full Screen RDP Session limited to 8 bit color on Sun Ray 2FS

When Microsoft introduced Service Pack 2 for Windows 2003 Server, they introduced a bug that prevented any RDP sessions greater than 1600x1200 from displaying in 24 bit color.  When Matt Hatley built a fresh Windows 2003 server for an event last August, we could not quite figure out why his full screen session on a dual headed Sun Ray 2FS would only display 8bit color even though we were telling the Sun Ray Windows Connector to connect in 24 bit color.  My server worked fine, his did not.  Turns out I was not current on my service packs and SP2 was to blame!  Sure enough, after applying SP2 to my server, I was limited to 8 bit color as well.  Since a customer just ran into this issue, I thought I'd post the fix and some answers.

Bear in mind that this is not just limited to the Sun Ray 2FS, which in a dual head setup runs 3840 x 1200, but this also happens on a multihead setup of any type Sun Rays.

You can apply this hotfix from Microsoft for Windows 2003 Server to get your higher color depth back for your larger RDP sessions.

For the record, you can go up to 4096x 2048 in an RDP session.  From a width perspective, that is about 3.2 Sun Ray 270's.  Four Sun Ray 270's would be 5120x1024 which is larger than the max resolution in width allowed by RDP.  If you wanted a four head setup, you could use four Sun Ray 2's with each screen limited to 1024x768 (4:3 maintained).

Microsoft Announcement: What it means to Thin Client Computing

Did you catch Microsoft's announcement today?  If you live in a world where things like VDI, WTS, RDP mean something to you, then you'll be excited to know that as of today anyone can view the Microsoft Remote Desktop Protocol specification.  Why is this news?  Because up until today this involved lawyers, contracts, large sums of money and view only access via a remote connection that even disabled your clipboard.  That's why.

My name is Craig Bender aka ThinGuy. I'm a Principal Software Developer for Oracle's Virtual Desktop Engineering group.

I architect and evangelize the use of Oracle's Desktop technology including Sun Ray, Secure Global Desktop, and Oracle VDI.
