But I'll share that I find that for laptops I have to use the clone display setting. Most games don't support the second video output so if that's an issue the only folk that could fix that is the game author.
I won't write anything about the game's video settings.
I've got my Dell laptop connected to my TV via HDMI. I can watch video clips no problem - sound and picture. I open a video game and the TV screen goes blank. I exit the game and the display returns.
Can anyone assist me with this?
