Hey guys. So i have a second monitor - Benq G2410HD, and i have set the refresh rate to 60 hz and the color 32bit.
It says its running from my GTX 780, but it seems its not as its like 20-30 HZ refresh rate. I usually fix these things, but i am clueless.

My XL2420T works great at 144hz, and it has the same information in properties.

Do you guys have any suggestions to why my second monitor hates me?

Thanks in advance.
