[SOLVED] which would give more perfomace and fps?

[9to5tech]

so would mirrored display give more perfomace than exteded display?

I don't know exactly myself, but the performance should be the same as long as the resolution doesn't change between the mirrored and extended.

So one of my friend said that extedning display will make the gpu draw more pixles so it will reduce perfomace, so is that actually true?

Say you have 2 x 1080p monitors (1920 by 1080). If you do a mirrored setup, you will have 4,147,200 pixels in total. If you do a extended setup, the amount of pixels remains the same, so there should be no performance difference.

ok so if ipad has exteded display support then it would be great right?

I don't know how that would work and if it is possible.

apple sucks so no extended display support

What system were you planning to connect the ipad to?

a monitor

 

[artavasdes]

a monitor

I meant the Operating system, whether if it is a mac or windows, because if it is a mac, I think there is a way to use the ipad as an extended display.

With extended displays, one will be primary, and that is where the games will run.
The secondary display will likely be static showing email or performance monitors.
They do not detract from gaming.
Mirroring with the same image on each display seems pointless to me.

Mirrored display throws up the same frame buffer onto every display connected to it. The GPU is not rendering extra pixels. However, it requires the displays to have the same configuration, down to the refresh rate.

Extending the displays allows independent configurations (different resolution and refresh rate) at the cost of some, but effectively trivial amounts of performance since it doesn't take that much to render the Windows desktop. Note however the frame buffer in extended displays is going to be a rectangle that fills every display's output. So if you had a 1440p and 1080p side by side, if you do a print screen, you'll get an image that's really 4480 x 1440, and the side with the 1080p monitor just has blank space.

The performance in a mirrored display setup entirely depends on the screen resolutions, refresh rates etc. There is no extra load on the GPU.
