Hi, I am planning a dual monitor setup for level designing in Unreal Engine which I started recently. I had one confusion regarding the setup on whether to go for an extra monitor and make a dual monitor setup of 1920x1080 monitors or get an LG ultrawide 3440x1440 monitor to work with my GTX 960 4GB. Now, I weighed the pros and cons but there is one thing that I cannot resolve. When using two monitors, if I want to do some rendering stuff or light building in Unreal Engine, I can switch of one monitor so that the GPU only has to power one monitor and the performance would increase whereas in an ultrawide monitor, all the pixels would be powered up and there may be a decrease in performance. Is this deduction correct? Can the switching off property really affect my performance that much?
