can you have 1 60hz monitor and 1 120hz monitor on the same comp?

adamknox · 7 Apr 2011 at 18:41

JUst recived my 120hz monitor today

is it possible to have one running at 102hz and the other at 60hz?? I dont know if its just me but im not really seeing any diff between 120 and 60 at mo (ive changed them in the control panel etc)

bee · 7 Apr 2011 at 22:06

yes, no problem at all

adamknox · 7 Apr 2011 at 22:08

hmm -_- then theres something wrong here... lol My 120hz monitor.. is the same as my 60hz monitor lol watching blue rays, gaming, moving windows about etc

ive changed it to 120hz in nvida panel as well.. -_-

Maybe you just simply can't tell the difference, some people find it hard to tell the difference between refresh rates, so long as it's above 40 to some people it doesn't matter if it's 60fps, 90fps or 120fps, it all looks fluid.

Yeah, it's all subjective, in the same way some people just can't hear the difference between 120kb/s mp3s or CD quality audio.

Of course there could be another underlying problem. What kind of FPS are you getting in games?

Well i unplugged the 60hz monitor and it did seem smoother

not that great in bluerays still though. Ive seen tv in the shops that are 120/100hz showing bluerays and they look very smooth compared to a normal 60hz tv.

I guess it is just me, i was expecting too much. most games i get 60fps altho some of the old ones i do get a lot higher.

if you look in the monitor control panel it should tell you what refresh rate it is currently operating at

Surveyor · 9 Apr 2011 at 12:09

Isn't Blu-ray typically 24fps?

Presumably it makes no difference if you watch on a 60Hz or 120Hz display.

when you see things like '600hz' on a tv, they are using processing to double/tripple/times by 10, then frame rate of the video its being fed.

pc monitors do not do this. that's why bluray is unaffected.

...

One is not going to see any difference between 60 and 120 Hz watching bluerays. Try and look at a game that is constantly running over 60+ FPS [Even if that means turning down your settings] to see the real difference.

When you see things like 600hz on a tv...its marketting bullsh*t.

Bubo · 11 Apr 2011 at 09:48

One thing which *may* affect you is your graphics card will never run at power saving 2D clocks when it should, i.e. on the desktop. I have a 120Hz with a 60Hz and have never been able to get a 280gtx or a 580gtx to run in 2D clock mode, it stays permanently at 3D clocks. When I was researching why this should be it suggested it was to do with running two monitors at different rates. It may also have been just running two monitors regardless but I'm pretty sure the refresh rate was also a factor.

yes this is true for dual monitors and also for a single monitor at 120hz but you can run the monitor at 110hz for desktop (no noticable difference at all) then force max refresh rate i.e 120 for games, using nvidia inspector and it will properly downclock to 2D clocks

Hi,

I am in a similar situation:

I will have the following on SLI 580s:

----60----
120-120-120

Is it possible to run the bottom 3 in 120hz while the top in 60?

Hi and welcome to the forum.

I didn't think you could run more than three monitors off SLI'd Nvidia cards.

I'm sure someone will correct me if I'm wrong.

JosephH · 29 Jul 2011 at 01:27

Cheers thank you

I hadn't considered that problem also, I'm not sure what the story is - whether I can run 4 monitors from SLI 580s

The other issue is the different Hz's

I'd appreciate if someone could shed some light

Saitex · 29 Jul 2011 at 09:59

Ok i haven't used 2/3 monitor setup myself, but after doing a bit of research i found that theres pretty much no answer on how to run 1x 120Hz and 2x 60Hz monitors in one set up, the only solution i found is to drop the Hz on the 120Hz monitor to match the 60Hz ones then it is possible, but as far for the set up which you said i don't think its possible, though who knows lets see what others got to say on this one, maybe there is a way xD

Ok after reading a bit more i noticed that ur aiming for ----60---- 120-120-120 i dont think that possible unless u put the 120hz monitors @ 60Hz then i think it would work. But like i said b4 there might be a way u never know xD

Akagi · 30 Jul 2011 at 14:11

they will definately work

i am unsure as to whether they will both run at 60hz because of the one slower monitor or not though :/

maybe the top monitor is a clone of the image on the center monitor, or maybe it runs from seperate graphics... but i dont know... guys..? can you run 4 screens on 580 sli or not?

The difference between 60Hz and 120Hz when working with 24p content is that 24p fits perfectly inside a 120Hz at 5Hz per frame. With a 60Hz setting, you can't divide it evenly by 24 and so the playback rate suffers from frame pulldown (perceived as a slightly jumpy experience). It is VERY noticable, and not one of these "my eyes are faster than 60Hz" things.

If you can set the monitor specifically to 24Hz or 120Hz then this problem goes away and you get a much more noticably smooth playback.

If the monitors are setup in 3d surround (and not just extra monitors you plugin and extend your desktop onto) then they'd all need to work at the lowest common denominator.

If you just plug them in as external monitors and configure them all separately, they can run at disparate frame rates just fine (I can have my primary monitor @ 120Hz and my TV @ 24Hz and drag windows back and forth, you can certainly 'feel' the refresh rate wall when the window starts to wrap onto the TV at such a low rate, but bluray playback is awesome).
