Splitters seem to just want to duplicate the signal but I think that'd be problematic given two different resolutions. Switches seem to want multiple inputs into one output, while I want to do one input to two outputs (toggled, not shared). What do I need for this? | ||

I think if you only want one device on at once, a passive splitter should work. I've never tried it and don't know much about what goes on in terms of handshaking and signalling (if there's a problem if connected to a device that's also powered off, that kind of thing). http://www.monoprice.com/Category?c_id=101&cp_id=10113&cs_id=1011303 A push-button selector switcher I think should work too...? Even if labeled for two inputs and one output. AFAIK it's just connecting copper. If it's not, it probably doesn't work. | ||

Ideally I want some kind of one click / push where it both switches output device (monitor <--> tv) and resolution simultaneously. If it's something I could control through the PC I can probably program that myself, but I expect it mostly to be something you physically do on the switch itself. | ||

Does a PCI-E 3.0 card work on a PCI-E 2.0 slot? and if it does, are there any repercussions? And performance wise, is the GTX 770 worth shelling out extra $$ versus the GTX 760? My current rig: Intel i5-2500k 8GB RAM GTX 560 (not the TI) | ||

I don't expect the price/performance to be better on launch, though. If you always wait for the next big thing, you'll never get anything. Just be aware of what's coming. Even GTX 760 should be a significant upgrade now.

I've just recently found out that having it connected and using it as a duplicate display (even when the TV isn't on) significantly lowers the framerate of my primary monitor. I've used 2 different monitors and both of them have had their framerate lowered by having the TV connected. Is this just a shortcoming of my graphics card? Is there a way to keep the framerate of my primary monitor up while having the TV connected?

And you mean the actual refreshes per second and not say some game's fps? Yes, I'm referring to the refresh rate. Sorry about that. The refresh rates of my current monitor and the TV are 60Hz. My old monitor's refresh rate is 30Hz. I can visibly see the difference in the refresh rate, as everything becomes much choppier and not nearly as smooth as seeing 60Hz. It's not choppy to the point of being unplayable, but enough to make it more difficult to play something like Starcraft 2. I don't know exactly how much the refresh rate is lowered. Speaking of which, when I display the FPS in Starcraft 2 while playing under the lowered refresh rate, the FPS counter still displays 100+ FPS. However, it is not visibly so. | ||

http://www.testufo.com/#test=frameskipping How's it look on the desktop? In other games? It kind of sounds like cloning is forcing VSync, and that's just it. | ||

There is one last thing that I'm unsure on: There always multiple brands to a card: EVGA, Gigabyte, Zotac, Asus, etc. Zotac GTX 760 is cheaper than most of the other brands thats available to me by $50 but whats the differene? EDIT: The difference in core clock and boost core is 150MHz and 100MHz respectively. | ||

It kind of sounds like cloning is forcing VSync, and that's just it. Just tried it. It does skip frames on that link. It skips every other square. It does look just as bad on the desktop, like when I'm scrolling down a page, it's not as smooth as it when the TV isn't connected. I'm not sure if it's as bad in other games, but I would guess that it isn't. For Diablo 3, it isn't as noticeable. Counter-Strike still plays optimally, though I haven't played it on the new monitor. Now that you mention VSync, I've noticed so minor screen tearing when watching videos on Youtube or VLC when the TV is connected. It usually creates a horizontal divide on the bottom half of the monitor that flickers sometimes. On the TV, there is no screen tearing and the refresh rate is fine. If VSync is the issue, is there a way to disable it? Or should I even disable it? | ||

I think it has to do with avoiding potential hardware damage trying to send more than what a device can handle. | ||

My current rig: Intel i5-2500k 8GB RAM GTX 560 (not the TI) 770 and 760 are both gk104: gk104 without any parts disabled (680/770) has 8 smx, 32 ROP's and 256 bit memory bus 760 has 2 of those 8 smx disabled, but does not lose anything else aside from VRAM clocks (it has worse memory, so loses like 10% bandwidth) typically the gap is about 1.3x in favor of the 770, but it's in a more awkward place IMO as it can't really fall into the super high end segment due to being somewhat limited by memory bandwidth, memory amount and ROP's (the next step up, 780, has a 50% wider memory bus and 50% more ROP's, as well as 3gb RAM over 2gb which is a safer bet for maxing games in the future) x8 2.0 is fast enough, it's a marginal difference on high end cards, you can benchmark twice and have the 2.0 outperform 3.0 by raw chance. If you're using a single GPU in x16 slot, having 2.0 and not 3.0 is not really something to worry about. I'd hang and wait for midrange maxwell card though, to upgrade two gens (400/500, 600/700, 800+) instead of one, given that we've had this gen for like two years straight already and it's not the best time to buy Just tried it. It does skip frames on that link. It skips every other square. This is a major problem, worse than being vsynced @30hz. | ||

Could you run two unrelated cards in a non-bridged setup (i.e. NOT sli/crossfire) and use the additional card for running additional monitors. What about 2 bridged + 1 not? And what if these 2 bridge + 1 not were not the same vendor (i.e. 2 nvidia + 1 amd)? | ||

And what if these 2 bridge + 1 not were not the same vendor (i.e. 2 nvidia + 1 amd)? There's something about some sort of clock generator hardware that's needed for the signal for DVI and HDMI. The normal cards have two of those and that's where that two-monitor-limit comes from. If you build something with monitors that are identical, always show same resolution and Hz, two ports on the card can share the same clock. That way, you can get to three monitors without DisplayPort on a normal card. It seems to me, people often report problems getting this to run. + Show Spoiler + Regarding resolution and Hz needing to be equal, what's perhaps actually important is the kHz the clock for the signal has to run at for going from pixel to pixel, not the Hz and resolution end result on the whole frame. This can sabotage the set-up for you, two screens showing same resolution and refresh rate might run differently behind the scenes as there's a whole bunch of numbers involved, empty lines at the top and end of the frame, empty pixels at the start and end of the line. At least that's what I think where the problems people report probably come from. You can run multiple graphics card without problems nowadays. Windows can do that fine, and the Intel and AMD and NVIDIA drivers all don't murder each other. What you might have overlooked, if you have graphics through your CPU and your board, that is usually by default disabled if the BIOS finds a graphics card at boot. You have to manually enable the integrated graphics in that case, but it does run fine afterwards, you will be able to connect monitors to the ports on the motherboard. I don't think SLI or Crossfire improves anything. The second card has no connection to the outside, only the first card does things like that, so the limits about the clock signals is still there? | ||
