monitor has stopped doing 144hz for some reason. its only 60hz now even though I have it set to 144hz and I have not changed anything since it was last working.

Do you have a 2nd monitor hooked up? It could be a game, some games don't seem to recognize higher than 60hz, though there are ways to work around that.

no just the one screen. yeah it seems some games only go to 60 fps with vsync on.

If you turn on stereoscopic 3D in the Nvidia control panel, then disable 3D when the game loads (ctrl-T), it will usually force the game to use 120hz when it doesn't normally support it. It is also how you get Lightboost enabled in 2D.

can someone with a 120/144 hz screen confirm that if you force vsync on from the cp for Dead Sapce 2 or 3 that it will only go to 60 fps?

The reason tearing occurs, is the video card is updating the screen during the refresh. If creating images at 25ms frame times (for 40 FPS), and the monitor is updating its image at 8ms, there will be 3 or 4 frames in a row that will not have a tear. You'll also find that the image that has a tear will be there half as long, as the monitor will update it with the new complete frame, 8ms later, rather than 16ms later.

The reality is, it is the half as much time with a visible tear that will probably matter the most.

Even if you were running 120fps on a 120Hz monitor you would have tearing if they weren't running in sync. The screen updating faster, or more often, just creates more frames that will have tears in them if you aren't using vsync.

You are confused. You are correct about getting screen tears regardless without v-sync. However, you only get tears when the video card updates an image. You'll get the same number tears with either system, because you still can only have 1 tear per frame. At 40 FPS, that is 40 tears, unless the tears lines up during a refresh, which isn't very often, and less often with a 60hz monitor.

On a 120hz monitor, those 40 tears get removed twice as fast as they will with a 60hz monitor, because it refreshes at a rate of 8ms instead of 16ms.

What you seem to be tripped up on, is thinking that a tear can occur twice from the same frame. It can't. Each frame can only produce 1 tear. Refreshing twice as fast gets rid of those tears quicker, and gets extra refreshes between frames.

Echos my thoughts precisely. Lightboost screens are good for gaming and gaming only - once you do anything on the desktop or outside of gaming, the poor colors and bad viewing angles are a complete eyesore and way too distracting. The difference compared to high end IPS panels is pretty dramatic.
Don't forget that LightBoost color quality varies a lot between monitors.

VG278H LightBoost has better colors than VG248QE non-LightBoost.

Also (especially on VG278H) don't forget to use these settings for LightBoost:
nVidia Control Panel Desktop Brightness=52%, Contrast=47%, Gamma=0.70, this fixes the LightBoost gamma bleaching effect and LightBoost looks good enough that I run it 24/7 even in the Desktop on VG278H. I can keep my monitor OSD to Contrast=90% with zero white/black clipping. Zero ugly purple tint, like VG248QE's (which forces you to adjust monitor OSD Contrast all the way down to about 45%, just to get rid of the purple LightBoost tinting problem).

also running adaptive half refresh rate seems to be the perfect setup for my needs. in games I dont get 72 fps then I will get little to no visible tearing anyway
72fps@144Hz still looks great and low-lag, though, and is superior motion-wise to a 60Hz monitor. So you're still getting 144Hz benefits. That said, that doesn't max out the potential of the monitor for motion blur sensitive people; wait till you see 120fps@120Hz strobed (especially on models with minimal LightBoost compromises). The main problem is the high GPU power needed to make LightBoost look good. LightBoost is a strobe mode, and strobed displays tend to look best during framerate-refreshrate matching. The difference between halfrate and fullrate animations become amplified when LightBoost is enabled, so of a sudden, it now becomes necessary to go full-framerate in order to get full LightBoost benefits. LightBoost doesn't really look good at half framerate for me. It is like owning a CRT that can only do 100-120Hz, so you suffer the half-framerate double-image effect of strobe displays (like 30fps@60Hz on CRT's and plasma's). It looks fine for some people, but some people dislike the double-image effect of 30fps@60Hz.

Plug the DVI cable into the other DVI port on your graphics card. Sometimes one of the DVI ports only does 60Hz.
as I said it was working fine so that would not be the issue. as already pointed out it appears some games dont go above 60 hz no matter what.

Most games can be forced into 120hz, with different work arounds, but v-sync sometimes cannot be raised above 60hz, like Dirt 2 or 3, Divinity 2 and others I forget.

btw I think I am just going to lower the refresh rate to 120. that way I can do adaptive half refresh for some games especially those games like Skyrim that have same issues above 60 fps.

and dark scenes on this screen look like complete garbage at least for movies. black is just crushed and even pixelated squares can be seen. also the top of the screen is quite a bit darker than the bottom.

lol I am really thinking a quality 2560x1440 screen might be a better choice.

You'll need to upgrade your GPU to push those pixels at the same framerate. Don't forget about that little bit too.

Meanwhile, you owe it to yourself to try out ToastyX's free Strobelight Utility. That way you can hit a keypress to switch between 144Hz non-LightBoost versus 120Hz LightBoost. Make sure you also test it with some older games that can run at full framerate locking (120fps@120Hz) for the maximum effect. You can also turn on/off LightBoost while viewing www.testufo.com/#test=photo and see the sudden ability to be able to count the windows in the castle at the top (whenever LightBoost is enabled). Being able to get that clarity in turning/panning/strafing in games.

That said, the better color of 1440p IPS may be the right fit for you, if you're only able to play at 72fps@144Hz anyway.
IPS color quality versus LightBoost motion quality; we still can't get the best-of-both-worlds in the same monitor yet.

another thing bothering me about this monitor is there is obvious banding in spots.

So, did you ignore my post? Because I clearly addressed the fact that some games are capped at 60fps by default, sometimes with or without v-sync. :p But if your issues extend beyond that, I am unsure what is causing that.

And the VG248QE simply does not excel at image quality from any standpoint. I've got mine "good enough" with ICC profiles (for with and without LB, because that does matter) and some minor tweaking using the monitor's menu itself. I don't need the best image quality to browse the internet, and smooth, blur-free motion is infinitely more beneficial to me in games than picture accuracy (again, monitor is "good enough" in that regard). Without smooth, blur-free motion, I easily get tired eyes, a headache, motion sickness, etc. Better picture quality doesn't actually produce tangible benefits for me other than "it looks better."

I also don't exactly have room on my desk for a 27" monitor, as my current 24" monitor is sitting quite snug between my two desktop speakers. And some games I can barely push at 100fps at 1080p. I'm not sacrificing picture settings (to an extent) to go to a higher resolution with much greater motion blur and a potentially lower refresh rate. 1080p works very well for me with my GTX 780 and 2500K @4.5GHz, even with a good portion of new, demanding games.

I'm confused. What else could better picture quality do? :confused:

I understand that you have some kind of condition or ailment that makes you ill/tired/have headaches unless you have very high framerates. That's your own personal situation, though. You can't really expect that to apply to anyone else.

The difference is that the distance of the tears is half that of a 60hz monitor making it all but impossible for most people to see. I use 120hz with no Vsync and I can't see tearing at all.

The motion blur of sample-and-hold hides tearing quite well.

When I turn on LightBoost, I can easily see tearing even at 300fps+ @ 120Hz, since the motion blur of regular 120Hz no longer masks tearing. So LightBoost motion looks much better with Adaptive VSYNC (less lag) or VSYNC ON (more lag). For a long time in the past, it was well known that tearing is much easier to see on CRT than on LCD.

(Sample-and-hold motion blur is the blur you see at www.testufo.com/#test=eyetracking ...)

yeah the in game vsync for all Dead Space games will use half refresh rate.

You can't use ingame vsync in any of the dead space games, you *must* use control panel or adaptive vsync or you will get a 30 fps framerate limit.

Pretty stupid that the game was designed that way, but it doesn't detract from the series. Dead Space 1-3 are some of my all time favorite games, definitely loved the entire series.

no it actually goes to half refresh rate. most people have 60 hz so it goes to 30 fps.

Uh, it only goes to half refresh rate if you use vsync in game. You must disable vsync in game and use the control panel vsync. It works, i've played through all of the DS games many times. Unless there is something wonky involving 120hz panels and Dead Space that i'm not aware of.

Summary:

Disable vsync in game
Enable vsync or use adaptive vsync in the NV control panel
Enjoy Dead Space at full refresh rate

um did you even read what you said to me first? you said the in game vsync goes to 30 fps. it goes to half refresh rate. I played Dead Space 1 at 42-43 fps with the in game vsync on on my 85 hz crt.

for some reason though Dead Space 3 will go to 30 fps with the in game vsync no matter what refresh rate I use.

EDIT: but yes Dead Space 3 can be played at 120 fps with vsync by seltecing 120 hz with in the game and using control panel vsync. earlier in this thread I did not notice that Dead Space 3 had select-able refresh rates.

EDIT 2: and I need to go back and edit my comment about jitter. I was testing in Dead Space 2 and 3 but was only at 60hz. at 120 hz there is basically no jitter at all.

okay after playing a few non demanding games at 144hz, I cant stand 60 hz any longer. even 40-50 fps without vsync used to feel smooth now it feels choppy and sluggish. I feel like I need at least 70 to 80 fps for games to feel smooth now and anything over a 100 feels great. I am so glad that there is hardly any tearing because maintaining 144 fps with vsync on with many games would be impossible on decent settings no matter how much gpu power you throw at it. Dead Space 3 with 144 hz and vsync is so damn smooth looking that is feels eerie.

Ha, I didn't say it would apply to anyone else. The OP mentioned jittering and such, which I am particularly sensitive to. Just mentioned what worked best for me in these situations and never said it would necessarily apply to others. I know I'm often in the minority when it comes to my preferences of smooth motion, v-sync, input lag, etc. :)
