Different refresh rates with monitor + TV possible?

[skeedo]

Have my VG248QE @144Hz (DVI link) and HDMI out going to Sony Bravia @60Hz with extended desktop. Anytime I play a game it freezes within about 5 seconds and I have to close it. If I try playing a video through Wmp Win 7 just starts completely flaking out and I'm not able to play the video fullscreen on either my monitor or TV. Setting both to 60Hz naturally solves the issue. Will it be possible to keep my monitor @144Hz? TV can't do more than 60hz. I've tried setting the scaling on both displays to GPU but this didn't make a difference (though I'm not sure that it should).

I have a similar dilemma: 144 Hz-capable monitor (new BenQ). HDTV hooked up to that machine as well as another @ 60 Hz. Well -- to be honest -- before installing the new monitor, I had to troubleshoot only getting 60 Hz with it. It had to have a DVI-D connection, and I disconnected the HDTV temporarily. So I -- myself -- am going to find out more specifically what I'm trying to only suggest here.

The other machine is no problem; the new monitor only allows 60 Hz for an HDMI connection, and that's the only option left after connecting the first machine to DVI.

But I had encountered this issue before with a KVM switch and several computers connected to the same monitor. You could switch between one configured at 60 Hz to another @ 75 Hz. Similarly here, I can switch my new monitor from a 120Hz setup to another computer configured at 60Hz.

The refresh rate is specific to the monitor and the computer connected to it. So I can't see why you can't have a monitor @ 120 and the HDTV connected to the same machine @60.

There may be "quirks," but you may be able to live with them. Just as likely -- no quirks whatsoever.

It won't hurt anything to find out, Bro!

If this is giving you trouble -- running one monitor at 144 and an HDTV at 60Hz -- and you are experiencing lockups, freezes, "flakey" behavior, I've determined on my end -- with my computer -- that I don't have a problem moving my Media Center window to the HDTV from a monitor configured as 120 Hz (HDTV @ 60). Doesn't miss a lick.

I can also try some games. But game settings can sometimes be specific to the monitor and the refresh rate, and may need to be changed or they would cause the same problem you've experienced.

I know this, because the problem emerged when I was playing this or that game on my new BenQ HD monitor @ 144 or 120 Hz refresh rate. Changing settings within the particular game made the problem disappear.

This is something you'll have to sort out yourself if it's a software problem such as that I experienced before getting wise about it. Somebody else may have different ideas, and I call on them to provide more advice if you need it.

But otherwise, running two displays off the same machine and graphics card with different refresh rates is apparently as easy and trouble-free as running different machines off the same monitor through a KVM switch with different refresh rate settings for each computer.

Again -- sometimes refresh rates, v-sync and other settings affecting the monitor behavior may be found within game settings. I'd look more carefully at that if I were having the same experience.

Welp, it looks like it's freakin Evga Precision that was causing all this crap! What a crock, I can't even begin to understand it at all. Games run flawlessly but I play a video and Win 7 acts like it just inhaled half a pound of bath salts. What tipped me off is this was happening even after unplugging TV from the HDMI out. I've switched to MSI Afterburner for the time being. Would be nice to not have to use any software at all but the fans just don't cool down GPU enough without.

At first I was clueless about what you meant by EVGA Precision -- too early and I'm still getting my coffee. Then I remembered my search for graphics-overclocking guides, and realized that was a "software" option to AfterBurner.

OK -- the fan control. I had concluded with regard to my ASUS motherboard that once you'd created a "fan-curve" with AI Suite, it was implemented in BIOS. But I never uninstalled AI Suite: I just don't run it in my system tray when I don't have to do so.

I'm facing another problem while I wait for NV tech support to get back after upgrading my support ticket to "second level." And I'm wondering if the power-consumption bug I'd noticed for myself and another member who "verified" it for his 980 cards (mine are 970) might not be a result of running AfterBurner. But the AfterBurner isn't a startup program, so I'm still clueless.

At least you've put to rest the issue of multi-monitor configurations with different resolutions, though.
