Screen Tearing Help (@144Hz)

[bleach]

Heya guys,

So I recently got the ASUS VG248QE monitor to fix my screen tearing problem, but I'm still getting some pretty noticeable tearing in TF2. I've gone into the nvidia control panel and desktop screen resolution tab and set my refresh rate to 144 Hz, I've tried capping my fps well below 144 (it even tears at 60), and I even put on vsync just to see (I could never use it full time), and its... still tearing... like almost worse than with vsync off. Does anyone have any suggestions to try and help me fix it?? Oh, and I've cloned my display onto my 1 monitor... that didn't work either, not very familiar with that concept though.

Video Card: EVGA GeForce GTX 550Ti
Video Card to Monitor Connection: DVI
(maybe its a video card or connectivity issue?)


Thanks so much for any help!

Did you try using adaptive vsync in Nvidia Control Panel? I think 120/144hz is for people with 2-4 780s in SLI etc. It takes high fps to vsync that high. Most graphics cards can only handle 60hz.

with adaptive vsync
if the fps is above the refresh rate itll be on
if its below the refresh rate itll be off

with a 120-140+hz monitor the fps will never be high enough to turn on vsync

Ah okay, somebody else actually mentioned a DVI-D cable and I'm using the standard one the monitor came with, I'm not sure if its DVI-D or not

You're right. I wasn't really thinking about that & just threw it out there. I told him he needs to SLI 3 or 4 780s/Titans to use that monitor. He made the screen tearing problem much worse by buying that monitor. His 550 would struggle with even 60hz.

The only real option is to turn off vsync & deal with the tearing. He can also reduce his refresh rate to 30 or 50 to vsync with that graphics card. Another option is to get a 580, 660 or 760 and set the refresh rate at 75 or 60.

Reason why you get screen tearing is that your graphics card is too weak to use 144 Mhz monitor. You need graphics card that can run your games at 144 fps, not some 60 fps like for normal monitors.
Your graphics card is weak for even normal monitor.
I would say GTX 770 minimum.

my friend has a 144hz monitor on a gts450.
it is his cord or powersupply confirmed by another screen owner.
if his cord is not good enough it will induce screentearing sme with PSU issues

the cord and psu will not caues screen tearing
no matter how bad they are

you get screen tearing if vsync is off
with vsync on (not adaptive) and the gpu cant hold 144hz, itll just display what full frames it can

But it should still synchronise the frames with the monitor to reduce tearing right? I have a 60Hz LG HDTV and my PC is powered by an A10 so I definitely don't get 60 fps on almost all games, yet v-sync is usually essential to reduce tearing (and it works)

yeah but vsync has that input lag that I don't really mind on 1p games, but I can't use it on multiplayer. I might also try different connections to see if it makes it any better. I'm not expecting to totally make it go away, especially because a higher frame rate is more important than graphics quality in tf2, but just making it less noticeable would be great

Undervoltge does cause problems with the display and or driver stability ect Bad Power is never good it can mess with the whole system.
and yes the cord can make a diferance.
so by your post if the monitor can use a HDMI or DVI or a RGB/VGA cable they will work the same with the same resolutions?.thats laughable

[rotNdude]

Screen tearing is caused by your video card sending partial frames to the monitor because the monitor can't keep up or the monitor is refreshing faster than the video card can update the input. It generally only shows up with games since those are the most video intensive.

When you enable v-sync, you ensure that each and every frame is synchronized with the monitor until the frame rate of the video card drops below the frame rate of the monitor.

I give up.good luck with your card hope you get it resolved

BS , sub par cables are known to interfere with signals , no matter if it's a DVI or HDMI cable , often enough i see people buy cheapo HDMI / DVI cables , and have problems..even some cables supplied with monitors are laughable and just barely meet specs , when you use them in a high performance setting , ie games etc they will start acting up.

there's a good reason a good HDMI or DVI cable is expensive...

thanks so much guys, I'll try HDMI next, cause I've got a cable, but I lost the adapter to my card, so I'll have to borrow my friends. but anyways, about vsync, it causes super noticeable input lag and really throws your aim off, so I know thats the fix to make tf2 look nice, but thats not really important

I have the same monitor and have been using it for over a year. I have my setup listed on my profile page. I get no screen tearing. Using x2 680 cards in SLI. Even when using x1 card I get no tearing and Vsync is always off for me. I would bet you have card that is in the early stages of failing. Even though those temps are not dangerous by any means, they are still rather high. Especially for idle. My cards idle at 35 (bottom) and 37 (top). HDMI isn't going to help in my opinion. If I'm not mistaking, HDMI cables can not produce 120Hz.
