I am a teacher and I need my laptop for presentation, without connecting to data show , I can say that the laptop is useless for me.
You are welcome.
Thank you very much for letting us know that information.
You mentioned that if video card gets disable the flickering problem stops. Most of the times that indicates that there might be a hardware problem with the laptop itself.
So, the next thing to do will be to get in contact with the manufacturer of the laptop, either to try the drivers that belong to them or to get further technical or warranty assistance.
Any questions, please let me know.
