XG270 has a dot crosshair with different colors

Side note though the Asus has noticeable input lag where the BenQ did not. It may be also possible the ASUS VG248QE used frame-buffered scaling, and the BENQ used real-time scaling. Also, at least when not doing scaling, I know the VG248QE and the XL2411T has the same input lag. Scaling is somethin...

Someone know how to force display scaling with a nvidia GPU (GTX 680), a BenQ xl2420T and windows 8.1? I can only choose GPU scaling in nvidia driver (i can choose display scaling with windows 7)

I don't understand how GPU scaling could add some input lag. GPU scaling can essentially copy from one (lower-resolution) frame buffer to another (higher-resolution) frame buffer, while scaling the image -- this would technically add latency. There are ways to do real-time, zero-buffered scaling by...

I don't understand how GPU scaling could add some input lag. I imagine that is some post process that only affects framerate. If not post process AA like FXAA would add some input lag too, no?
No one knows more about this?

First, sorry for my really poor english, i'm french ;) I have read some things about scaling and input lag here: http://www.overclock.net/t/1388836/input-lag-in-nvidia-drivers Since my windows 8 (8.1) update, i can't use the "display scaling" option in my nvidia driver (331.82) with my BenQ xl2420t ...
