Is it possible to switch the input ports fast? The older models have uncomfortable sensor keys and menu strukture to do this. A remote control would be nice too! A Monitor like this makes sence to use it for changing different sources.

What monitor would work best for me if I have EVGA GeForce GTX 970? 

Asked by: Rustywell
1440p is tougher to drive. I believe roughly by 30% . You will do alright with a 970, but probably not going to get even all High settings.

It touts the monitor as 75 refresh rate but when looking at the manual I only see a maximum of 60 refresh rate does anyone know which refresh rate is correct?

Asked by: pjtrai
We appreciate your interest in this monitor. Thank you for bringing this information to our attention. It seems that the information on our website is incorrect. This model appears to be capable of 60Hz display as a recommended, optimal operation. We will forward this information to our marketing division for review and correction.
