ATI - Dual Monitor - Video

[resglower]

Has anyone successfully managed to get video displayed on both monitors? Unlike in XP when I watch a video, it is only played back on my primary monitor.

I had to use the windows display settings to set the default monitor. Now both are working

Dual Head ASUS EAH3650 Silent -Vista drivers, Catalyst beta W7- works perfectly in my W7x64 C2D8GB

You mean ATI Theatre mode where the video overlay spans mirrored monitors?

Works fine for me using the WDDM 1.1 drivers and an HD 4850

Works fine for me using the WDDM 1.1 drivers and an HD 4850

Just installed Win7 RC on Dell 64 bit (upgraded from Vista sp2), using NVIDIA Quadro NVS290 adapter. Cannot get dual monitors to work - using DVI cable - in NVIDIA setup, as well as win display setup, it shows both monitors, but will not display on second monitor - it just stays asleep. I've downloaded the Win7 64 bit driver from NVIDIA - still doesn't work - these worked fine on Vista 64. Any ideas?

General troubleshooting: swap monitor cable connections. If the same monitor's dead on a different cable then it's the monitor or how it interacts with Windows 7. If it's not then it's the cable and buy an new one.

swapped out monitor, swapped out cables - no change in results.

Elucidate please. Swapped or "swapped out" means something subtly different. Do you have three monitors or two? When you swapped monitors was the originally non-functional monitor still under test or was it removed from the equation?

Apply logic -- if the bad monitor is still bad on a different cable that works with another monitor then the monitor's at fault. If the bad monitor works on that cable then it's the cable. Which is it?

 

[simplysql]

logic applied - it worked fine on Windows Vista - does not work on Windows 7 - software problem, not hardware problem

But which component is incompatible? Cable or monitor? The biggest change in Windows 7 in this department is it's complete reliance on monitor EDID information. If the cable doesn't pass it then anything goes.

interesting - I have swapped (changed) the monitor cables when I changed the monitors, did not change the dvi connector.

So it's the connector on the video card? Is are there any adapters involved like VGA-DVI, etc? The monitor works when connected to the other connector?

 

[simplysql]

just changed out the DVI connector as well- that did not fix the problem either - I"m really stumped.

Have you tried querying the monitor using MonInfo? http://www.entechtaiwan.com/files/moninfo.exe

fixed it - went to NVIDIA site and downloaded the VISTA 64 display drivers - installed those over the WIN7 drivers I had loaded earlier, and the monitor turned right on. I knew it was software, not hardware Thanks for all your responses!

I can't get my 46" LCD TV and my 20" monitor to both work at the same time with Win7 like I can in WinXP. I use HDMI connection between the two. I suppose it's an ATI Catalyst problem as of this time.
