Studio Hybrid 140G won't POST using VGA adapter

Got the same problem.
I connected 2 displays, one on DVI and one on VGA.
I can only start with the VGA disconnected.

Once Windows run, i can connect the VGA Monnitor and Use it...

I have had a very similar problem and it is not resolvable. I am trying to return the computer. If I can't return it I will just trash and take the loss. I believe the design of this computer is defective in some way. We had the same monitor issue. Dell told us our monitor was no good and sold us another one. Same problem. Switching monitors worked for a while. So DONT turn the computer off, leave it on all the time. If you turn it off, then you may have to switch monitors to get it to come back on. We have two monitors that we just switch back and forth between. But after a few months, even that won't work. So we have had the motherboard replaced, the software reset 4 or 5 times. Pretty much we hardly use the computer because it crashes so frequently. So, was working a few days ago, but now, no video once again, and switching monitors doesn't work now. I was excited when I read that someone had success with VGA but not DVI, but my studio hybrid only has a port for a DVI cable, so no luck. We have been trying to resolve this since we got the computer last August. I would like my money back, but don't know if that will be successful. I'd appreciate any tips that would make it work permanently, otherwise it's a big pile of money and time that we will be sending to the trash.

How do you do that? Mine only has one video port--for the DVI.

The computer should have 2 video outputs, at least mine does.  The connections are DVI and HDMI.  Both can be used for connecting monitors.  If you get the proper adapters, you can use VGA as well.  If you are having a problem using the DVI connection, maybe you can try getting an adapter and using VGA, or if your computer has an HDMI port like mine does, then maybe you can try using the HDMI port with a DVI adapter.  Here are some links to adapters that will work:

I have exactly the same problem. It's not acceptable to have to disconnect the monitor for reboots. This has to be a bios issue and as such is unresolved in the A10 bios.

With all due respect, changing your monitor is not a solution. The problem is with the computer and its inability to post correctly, not with the monitor.

i used my own dvi - vga adaptor and it worked fine. Dell's dvi - vga/dvi lead is the problem

What is worse is that if you don't have a normal USB keyboard attached it won't boot when you go from A.09 to A.10.  With A10, you have to go into the BIOS and tell it to not display keyboard errors... this is common historically, but its something that stumped the dell technicial (joke, ahaha) and they sent me a brand new shuttle hybrid with faster cpu and vista ultimate to fix my problem.... I set it up at my desk, and when I went to move it into the living room on 50" plasma with wirelss media center controls, it would not boot unless I disconnected everything (except power).

Since the old computer did this only after bios upgrade, I figured it had to be bios setting, found that keyboard one, which should be ignore keyboard errors, rather than don't display keyboard errors... since it HANGS w/o a keyboard.

Why else would we pay a premium price for these things if not to use them in home theater setting.... yet they don't work well headless... obviously I'm not the only one.

Before the A.10 bios fiasco, my biggest issue was that when everythign was working good... I'd switch from media center to regular TV... then when I switched back (basically changing HDMI inputs on my TV) the hybrid video would wig out and switch down to 800x600 except my TV couldn't display that.  I had to remote login with VNC (very handy) and fix the resolution... except 1080p was gone.... I had to go with 720p..... after a full reboot, 1080p would be back in list, though that's two manual resolution changes every time I switch to DVD or regular TV inputs on my 50" plasma.

but, in the end, Dell ended up giving me free Blue-Ray upgrade, 2.5 to 2.6Ghz upgrade, and Vista Ultimate upgrade (from basic).... so I'm not complaining, I'll drop another $20 on it and use the Vista Premium upgrade I had to buy for the original (cause I didn't know you had to have Premium or higher for MC) on my desktop.

The only reason I want the split is so I can have a 14" VGA to the side for bootup and troubleshooting.... and maybe a TV guide or something.
