120hz + 60hz monitor

[Big WigglyStyle]

I was wondering if I decided to get a 120hz monitor @ 1920x1080 and paired it next to my current 1920x1080 60hz monitor if I would get any weird issues. I won't be using them both for gaming just the 120hz monitor and the 60hz one will be a temp/youtube/web browser thing on the side. I was wondering if A. the 120hz would default to 60hz and if B. I will get any other odd issues I may be unaware of. If I won't have any problems can someone recommend some 23-24" 120hz monitors to me for under 250 USD. I'm willing to push up to 300 if need be.

I'll break out my 60Hz monitor tomorrow evening and check for ya mate. Never thought about it to tell ya the truth.

I had one monitor at 120hz and another at 60hz for about 10 minutes before I just about threw them out the window. I don't know if it's the same with all monitors, but the combo didn't work at all. I would drag a window from 120 to 60 and it would stutter. WMP would freeze. Artifacts appeared during rendering, modelling, editing etc. It was visually disturbing to see how smooth the 120hz was and look over at this stuttering POS at 60hz. If I could have had them working together properly it wouldn't be as bad.

I have a VG278H and a Samsung 22" something or other. My GPU is a GTX 590. If anyone else has this monitor and has the same issues, please advise me on what I may be doing wrong.

I'm sure it confuses the driver, the V-Sync on both monitors is different. If your desktop is Video synced at 30Hz on the 120Hz, that is ratio of 1/4. That same 1/4 on the 60Hz monitor put's it at 15Hz(=studder)

I guess it's like how Nvidia cards don't like running muli-monitors where they are different resolutions, it forces the card te render the image at each resolution, but with Hz instead.

Ohhh. So two different resolution monitors at different refresh rates on an Nvidia GPU won't work?

I don't think it's Nvidia cards fault, I was just using that as an example. I know when you add a second monitor at a differnt resolution to a Nvidia card It doesn't know what to do, so it renders the same thing in both resolutions, and you take a huge hit in performance.

I never owned an AMD card, but I read they don't take as big of a hit when running different resolutions.

Like S_I_N said, I never really thought about running 2 differnt refreash rates before, but I'm sure it causes the grapgics cards a whole lot of confusion. Like you having 2 cell phones, one on each ear, trying to talk to 2 people at the same time.

If each one took turns talking you would be fine, but they wouldn't know when the other was talking, and they would both talk over each other, confusing you. I'm sure there would be alot of awkward pauses in there where no one was talking and times where some one would studder as they started talking after a pause, only to realise someone else starting to talk also.

well I've run two different resolutions on my GTX 570 both via DVI and I didn't have any issues other than one was very ugly and had terrible color accuracy compared to the other one was a 1280x720 other is my current 1920x1080 which is why I was wondering if a 120hz would cause issues

You would have to lower the 120hz monitor down to 60hz. The GPU is only able to process one or the other.

well that sucks guess I will go with my original plan and grab a pair of denon ahd 2000's instead of the monitor thanks guys

I'm sure you'd have to set the refresh rates equal for decent performance. But putting a 120Hz monitor into 60Hz mode is like blasphemy.

I JUST found out how to get 120hz and 60hz to work properly with cards in SLI or cards with dual GPUs!

You have to disable SLI in dual gpu cards to allow them to render two monitors independently.

well I only have a single GTX 570
