2 Monitors - Question

Jborg · Oct 5, 2015

So last night I picked up another monitor... its an ASUS VE247H.

Just basically had a quick question regarding using 2 monitors at the same time.

My main use for the second monitor is to reference drawings for design/CAD.

So my question has to do with gaming, and having the 2nd monitor plugged in at the same time.

Do I need to physically unplug the DVI cable from the video card so it only processes 1 resoulution on 1 screen?

Or can i leave the second monitor plugged in and simply just turn it off while I game?

I know that running 2 screens at 1920/1080 forces the GPU to process both resolutions, and can effect FPS.

Any info is appreciated.

Thanks again,

I run two 1080p screens and have no FPS issues that I have ever noticed because of it...sure if I measured I bet there'd be something to measure...but I get high FPS in all my games. I've ran dual screens for year... as second idle screen at 1080 isn't going to bog you down. Hell there are times where I'm browsing, watching movies or even on a different game on the second monitor (depending on the game(s) and support for full screen windowed mode).

No, there is no difference in gaming, and no, you don't need to unplug your monitor while gaming. The only difference while having 2 monitors is slightly higher idle clocks, meaning slightly higher power consumption and slightly higher temps. Other than that - no reason for concern.

Yeah I guess it depends how GPU heavy the games might be.

I am mainly playing Witcher 3 / GTA 5 at the moment, playing on High/Very High detail for both games (No MSAA/HAirworks)

I do see some fluctuation in FPS, nothing major as you mentioned, but still curious on my original question.

EDIT: Basically got my answer above, any other input is welcome though.

Thanks,

Even my idle clocks don't stay elevated... if I have something rendered via game or browser they will raise until the processing power is no longer necessary. Maybe things are different with the 9xx series?

My clocks jump around quite often even on idle, especially when using a browser, but thats probably due to HW acceleration in certain cases. That and both of my monitors are in constant use.
