Video card suddenly messes up

Take your friend/family monitor and plug it in your machine. If the problem still the you graphic card is bad. If not then check monitor cable or update your graphic card driver.

Isolate the problem to see if it's the screen or video card by connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok without a problem then your original screen is bad and your video card is good. If the Borrowed monitor displays the same problems as your original then your video card inside the computer is bad.

Sounds like your monitor is bad. Try another monitor because if the video card was bad and the monitor is working you would get a No Signal message on the screen. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok, then your original monitor is bad. If the Borrowed monitor does the same as your original monitor and does not display anything, then there is an issue with your video card.

If your monitor works fine on another computer then most possibly its your video card since you said nothing comes on. Usually if its the operating system you should see the computer info before it goes to a blank screen. If you have an add on video card try using the integrated video card or vise versa. You can also use a known good video card from another computer.

Because Sony Vegas support WMV, MPG (MPEG-1, MPEG-2, MPEG-4), MP4, MOV, ASF, SWF, FLV, etc. It doesn't support .avi format. So I want to know your video files format.

Good luck~~

plug your LG display into the DVI port and the BENQ into the VGA? it may just be a random compatability error.

If you've replaced the monitor with a new one, it's probably not a monitor problem. Try uninstalling the video card and use the motherboard's on-board video. If that's not working, check into getting a new motherboard. If it works fine, check the settings on your video card.

Hi, if you loose video on both monitors, that means there is a problem with the video cards. I guess you already tried to update the video drivers to the latest ones, so the only thing remaining is maybe an hardware problem with the video card. Try to play your game at a lower screen resolution and see what happens. Also, if you have a flatscreen monitor, try to lower the refresh rate at the default 65Hz or 70Hz. If after 30 min or so you still loose your image, make sure the monitors are still powered (usually the green light will turn orange awaiting a singal to open and turn green then) Some video cards got some issues with heat after a certain amount of time. Something about GNU but i'm not 100% positive. Anyway, in that case, you may have to replace your video card, god of waranty please be with us! good luck

This "red preview screen" is usually caused when your project consists of: 1. Too many video/sound layers.
2. sometimes it's enough to have a single layer project which has a 'heavy' picture, i.e., resolution higher than 300pix/inch or/and excessive width&height measurements.
Vegas will then--in some cases--stop functioning.
The easiest solution will be to edit your picture and reduce the resolution with e.g., Photoshop by "Resizing" the "Image size".
Another possibility is to locate more RAM (memory) to Vegas in the program Preferences-->Video (tab). It's 128mb by default. If you enough memory in your hardware, try raising the value.

You pointed out that the crash happens when you start the program. It could very well be that your software tries to load your recent project. If you cannot get into Vegas's Preferences--for the software always crashes, then try pressing the Escon your keyborad as soon as the splash screen disappears. Then you will be able to start a new 'lighter' project or just untwik in Preferences-->General(tab)-->"Automatically open last project on startup".

you have tried differrent setting in your video resolutions, what you need is just return to your default settings
