What would this achieve? Everything is completely normal on my computer monitors

Don't confuse 'expensive' with 'good quality'. Any HDMI cable from monoprice.com is going to be v1.4, and you'll get a great deal on it. A rule of thumb is to simply steer clear of retail stores for cabling as this is the largest mark-up item they have. I think the average is somewhere around 1000% mark-up for cables at retail. (buying a cable for $2 and selling for $20)

I know it. I will try to find a v1.4 cable on Amazon or eBay sadly monoprice.com is US and I'm in UK! :)

Single GPU would elevate the micro-stutters you are experiencing.

That choppyness are the inconsistant frames being rendered by each card.
No card can operate 100% like the other, thus creating tiny micro-stutters.

Even running at 400FPS, stutters happen every few frames, making it seem like 10fps.

But with one card running at 60 or less without these stutters look MUCH better in comparison.

Food for thought - 400fps is the average overall calculated every few miliseconds,
the microstutters happen at an even smaller time than that, thus not effecting the FPS but effecting the consistency and fluidness of the frames

hope this helps :)

cause trying one card would rule out a possible SLI problem with output to a tv

its called trouble shooting

we think of possible solutions and provide them...its to rule out possible causes

if you use one card, and it works fine, then we would know its related directly to the SLI and output to the TV
if its still not ok, then it has nothing to do with SLI and we move on

however taking the card out is fairly quick and easy...


and i'm 99% sure you are probably using DVI to your monitors and not HDMI
if one of your monitors can

try the HDMI to a monitor instead
see if its still choppy

this is an older thread but the first thing I would think that would cause stutters is codec problems what I would have done is loaded the vid onto VLC and see if the stutter goes away or is better if it did or plays better then it would definitely be a codec problem

So does it flicker/stutter only on the HDTV? Not on the u2711?

If so then 10/1 it is going to be a cable issue.

as shadow pointed out. its an older thread. never noticed just saw it as "new" so replied

YOYOO! I MAY HAVE A SOLUTION!

If you are running a 120hz monitor you MAY experience frame drops/stutters every few seconds/miliseconds or what ever.

I JUST experienced this like 2 seconds ago. I dont know why, but i forced 60hz and no more stuttering.

Yes, first thing I would've thought to check would be refresh rate if I was OP. I don't see him mentioning that he checked that in here, however 10e who was the first to reply asked him to check this.
