Welcome to the forum.
With the "incompatible display driver" error message, it usually means that your video driver is obsolete.
- What OS version are you running PrE 12 on?
- What is your GPU, i.e. your display card/chip, and both make and model?
- What is the installed version of your video driver for that GPU?
- Is that the latest from the nVidia, or AMD/ATI Web site? Check this out for your model of GPU from the mfgr's. Web site, and do not trust your OS to tell if you have the latest.
1)I'm running Window 7Pro
2) Display adapters has 3 listed. They are
AMD Radeon HD 7650M
Intel HD Graphics 4000
3) not sure how to find this. Under Monitors, it looks like it only shows the laptop monitor. Says, "Generic PnP Monitor"
4). I'm not recognizing what you are asking.
I have a Dell S2330MX. I'm not seeing it under MONITORS. Maybe that is the problem.
Please assure that you have the latest version of your video card/graphics card according to the web site of the manufacturer of the card. AMD - for example http://support.amd.com/en-us
When you get the display error message, is there a video/graphics card name listed on the error message?
What is that Unknown Device...if you double click it, what information do you find for it?
The answers may come in disabling one of the integrated card. But if this is something that worked before but not now, I wonder about that. When you say that you used software before was the software Premiere Elements?
Deleting the BadDrivers.txt file may be indicated. If so,
Local Disc C
and in the Premiere Elements Folder is the BadDrivers.txt file that you delete. This BadDrivers.txt file is a file in the Premiere Elements Folder which also has folders. You do not want anything in those folders, just the BadDrivers.txt file in the Premiere Elements Folder in the path cited above.
Make sure that you are working with Folder Option Show Hidden Files, Folders, and Drives active so that you can see the path to the BadDrivers.txt file.
Any questions or clarification needed, please do not hesitate to ask.
A laptop with dual (3 ???) graphics adapters MAY need to have the low power Intel motherboard turned off so only the high power AMD is used
Dual video problems (some for Premiere Pro, but the idea is the same)
