Dual HDMI?

[The_wand_mirror]

So i heard a Full HD television could reduce your PC's performance when you connect it to your videocard.

So i was thinking could there be some dual HDMI option, for example when one TV has multiple HDMI inputs could i insert two HDMI cables into my videocard and both in the TV and configure it as a sort of SLI/Crossfire?

Why would you do that?
As far as I know, each HDMI-socket on the TV directs to each a channel, meaning the effect would simply be that you would have the same picture on both HDMI-1 and HDMI-2 for instance.

I don't know any details around it, and I haven't tried HDMI->TV (simply because nVidia GPUs generally don't come with HDMI-socket), but I'd assume it's just because of the resolution. A Full HD TV has a resolution of 1920x1080, it might even demand it. I don't think you will notice any difference if you move from a 24" screen, with 1920x1080/1200 resolution, to a Full HD TV.

I mean that the performance might be decreased as videocards are not designed to work with TV's. They will have to handle a bigger screen and thus my FPS might drop or something like that.

But the amount of the pixels is even less on Full HD TV with 1080 resoltion. It is not the size that matters it is the amount of pixels.
Simple example: a 24'' 1920*1200 works slower as a 42'' Full HD TV with 1920*1080.

A HDTV is the same as every other monitor you attach to your graphic card, the only difference is it generally is larger than a lot of cheap screens.

Basically, the resolution of HD TVs and any monitor with higher res is so much, that it can cause slowdowns in various games like crysis due to the extra GRAM demands and such. It just means you will need a better graphic card to run them as well as they run on smaller resolutions.

If you provide an HDTV with a small resolution like 1024*7xx it will perform as well as if you were providing that resolution to a display of just that size. In the end performance decreases as the number of pixels to render increases (which is x*y pixels) however this improves vsual details, so it is a trade off you have to consider.

If you notice performance problems, just do not run the TV at its full resolution and take a slightly smaller one (the TV should scale it up).
Most PS3 and 360 games are only 7xxp and people do not complain about their resolution.

As I said, it's the resolution, and not the real size, of the display that matters. If you are running 1920x1080 resolution on your computer, then there will be no difference when you connect to even a 101" screen as long as the resolution is Full HD (ie 1920x1080).

Oh okay, i guess that guy who told me doesn't know what he's talking about then.

Well, if he was talking about size, ie 24" compared to 32" etc, then he doesn't have a clue, no.
