Can't use multi monitor under windosw7

[questerymj]

Hello all,

 

Suddenly I can't use multi monitor under windows7 last night. The same setting worked until last night. The same config file still worked under windows XP now, and I had setting expand mode in windosw7, BS runs ok but just don't rendering the abris like before.:cry:

 

Does anyone know how to cure this? I don't want to reinstall W7 for this...

need more information what monitors, what Graphics card, drivers, did you make sure it's running iin window mode and not full screen?

Hello Mastiff, thanks for the reply.

 

I'm using LCD-800U usb-powered monitor that using display link chip. Drivers are auto installed by windows7 and I don't know the exact version of it.

 

I'm very sure I'm in window mode because the sub monitor worked in WXP 32bit with same config file. I'm running BS from same folder under both WXP32bit and W764bit.

 

In one night before the problem happened, I tried to run BS under Windows7( I never try this before because I need to use register key one time) to test if BS run faster under W7. I successful make abris display in sub monitor and it is far faster than WXP( 16-21 fps in WXP32bit and stable 30fps under W7). But in the very next day it failed.:(

 

I can see the BS loading screen in main monitor stretched( window mode and customed resolution worked) and I can see the cockpit cursor in sub monitor, but just no graphic rendering.

 

I know there very few people here using these monitors, just try to see if anyone experienced this and share the solution if possible.

did you go into the display-link advanced options,

ans check to see if the monitors are aligned in correct .lua settings?

make sure also the settings for that monitor are correct for refresh rates. and resolution settings.

Thanks for reply again Mastiff, I'd found the problem myself.:)

 

I found that if I disable AERO under W7 (switch to basic desktop) the render will be disable anyway. I switched to basic desktop to try to gain more FPS and forgot this. Once I switch back to AERO theme, the sub monitor back to worked! Any one who use usb-powered monitor with displaylink chip and W7 like me should notice to this.

 

And I do some test myself and here are something I found for other usb-powered monitor users:

 

1.BS runs far better under W7 64bit than WXP under window mode. I can get 40~60 fps in W7 64bit, and only 14-20 fps in XP. Evidently BS prefer W7 or 64bit OS if you want to use window mode.

 

2.If you don't install any core manager app from displaylink and just let W7 to get the driver by itself, You can enable the usb-power monitor with "optimize for video" and try, You may see a lower quality graphic in the sub monitor (in my case, it looks like 300x400 rather than original 600x800) but the FPS will greatly increased. My test result is 58-60 fps in "optimize for video" mode and 40-45 fps in normal mode. This is very amazing, I NEVER see BS runs with 60fps under window mode before.

 

But once you install the core manager app from displylink site, no matter you enable "optimize for video" or not(anyway you get a lower quality graphic if you enable it) , the fps will stay the same, and damn stable in 40 fps even in big battle or near city. I don't know why, but stable 40fps is fairly nice for me.

 

3.Enable vertical sync and AA almost no hit to fps in my system (coredual E6400/GTX280). I'm not sure if vertical sync make BS more smoother, but looks like not bad to have it if you can reach 40fps.

ok yes I had posted that sugestion to some else didn't get to you about that yet.

 

but yes win7 64 bit basic colors which disables aero, you will lose the usb capability.

 

so yes aero has to be on or advanced personalized themes settings.
