Dual display affect GPU performance?

[-Slacker-]

I'm thinking of connecting my TV to my desktop, which I plan to only use when my crappy 17" inch is turned off (and vice verso). Will having two displays connected to the GPU hamper performance when one is off?

I have been using dual displays for years and have never noticed any problems at all. I usually just leave both on when gaming.

While probably not the best benchmark for the occasion I ran Furmark on 2 and 1 monitors. The score was 775 and 777 respectively.

In more realworld things such as games I noticed that my framerates did drop a little bit. Probably around 5% maybe? I am running an ancient 4890 though, so I'd imagine modern cards get affected even less.

Another thing is I generally use borderless windowed mode with multiple monitors so multitasking is absolutely instant. That affects framerates even more, and notice minimums drop quite drastically.

The good thing is it is completely effortless to switch between using both or only a single. Windows + P brings up a menu in which you can choose to use the main, duplicate, extend (the good one), or the secondary monitor.

There is probably a slight decrease with both monitors on. I turn off my second monitor in CCC while gaming, and I'm pretty sure that nullifies the slight performance decrease.

Basicly no difference. 2x2407fpw here.

Nice, so minimal to no performance hit.

Ok another quick question and then I'm done:

Can I connect any HDMI cable form my gtx 460 to a samsung UE32C6700 TV, like this one??

apologies for the n00b question, but I'm not exactly a HDMI expert, considering the monitor I still use

Should be fine.

The only time I notice a difference is when I run a game in windowed mode so I can quickly alt-tab into the web browser on another monitor.

This.

People don't understand why my laptop fans are always spinning so loudly... :biggrin:
