I'm seeing doubledouble but it ain't movin'
Published on April 3, 2007 By Phoon In
I have a beasty system at work, which I have installed Vista Ultimate on.
I have 2, 256MB Video cards.. hence 4 monitors.  
If I try to run DreamScenes here's the message I get...

Windows DreamScene can't run as your desktop is now configured.
Windows DreamScene cannot run because the total desktop size exceeds the primary video adapters's maximum texture size.


Help?

get newer video cards

wrong answer Razster   
There is nothing wrong with these cards.
One is a Pcie Nvidia Quadro NVS 285 256MB, the other is a PCI Nvidia GeForce FX5200 w 256MB memory. All with the latest drivers.

These cards are well more than capable of running DreamScene. It just doesn't like me doing it on 4 monitors. I can run it on up to 3 connected monitors but when I extend my desktop to the 4th one DS won't run.

Show off.

I just wish it was my HOME system. It's my work PC   

Dell Precision 690 workstation, Dual Xeon 1.6Ghz Dual Core Processors, 1066Mhz Bus, 2 GB Ram, 2 160GB SATA Hard Drives.. 
Then I come home to my lowly system which gets pissed if I even break out the Vista DVD

Have you tried lowering the resolution on all of the monitors just to see if its a total desktop resolution issue?

lowering the resolution


I'd rather stick a red hot poker in my eye  
I can try it, but I would rather not have DreamScenes than to live with 1024x768.

Four monitors?

Not being a techy, I'm just trying to imagine what the hell you'd need four monitors for anyway.


I hate you.

Well, I do quite a bit with VMWare so I have a virtual machine or 2 or 3 running.
I keep domain administration tools open.
Outlook,
Reading documentation and connected to another system with Dameware or remote desktop. Writing installation proceedures etc.

One of the monitors is also connected to an 8 port KVM so I can be doing builds on up to 5 more PC's at a time.

So, I have quite a bit going on. I hate minimizing unless I have to.

I have two 20" and two 30" Dell monitors on my GB. They are most excellent for "wow" factor when clients come in for a meeting. Now if I can only get rid of the damn black bars between the monitors. One day when I'm stupid rich I guess I'll get the Athens monitor array from www.l-computer.com. but sadly it has the bars as well albeit very thin ones.

And that's why I'm not a techy. I like to have one monitor that works . . . and once I'm good with that, I'm good to go. Give me my OD and I'm set.

It won't work on my 256mb X850XT either in dual monitor mode.

What a joke.... "cutting edge" and it can't handle more than one frackin monitor.

Oh come on! I hate it when people dis software like that.

Even I can take a guess at what is really going on: because it *is* cutting edge, DreamScenes uses hardware acceleration in order not to slow your PC down to a crawl with wallpaper animation. The worst performance killer in terms of graphics is transferring bitmaps from main memory into video memory, so, in order to prevent this, DreamScenes probably tries to load the bitmaps 'permanently' into the video card RAM as a texture. It's then up to the GPU, instead of the CPU, to take over the job of animating the wallpaper.

I never tried running DreamScenes, but I think the problem here is that either it is trying to stretch the wallpaper from monitor 1 to monitor 4 (instead of making each monitor have its own individual animated wallpaper) which requires a HUGE texture OR, with each video card supporting two monitors at high resolution, they simply don't have enough RAM left to store the required textures.

The same thing can happen with the WDM in Vista, except Microsoft developed a method to store window bitmaps in main memory when the system runs out of video card memory. With an animated wallpaper, though, I'm not sure this would be a good solution - performance would suffer tremendously.

Most people call it "cutting edge" because it’s the latest thing, but some people call it “cutting edge” because it's enters first. When you use a knife, it’s the cutting edge that gets the glory when it cuts and the abuse when it hits something hard.

I dunno, but an X850 driving 2 monitors is rather far from cutting edge.
Respect your graphics card- WDM isn't like simple GDI calls that can be processed easily. And the X850XT is 2.5-year tech, to add unto it.
