Screen tearing

Hi Guys,

I recently was messing around overclocking my ****** gfx card, it started to cause major screen tears so i reset everything back to default which seemed to have stopped the tearing. But it has been happening increasingly for the past few days.

any idea what the problem is or how to fix it? or did i **** up my gfx card? lol
 
Screen tearing occurs when your frame rate exceeds the refresh rate of you monitor.

The solutions - Use v-sync, use adaptive sync, or put a framerate cap in place (either in game or with 3rd party software).
 
thanks DazQ87, ive turned on Vsync but i'm still getting major screen tears. if that was it is? its happening even on desktop, big horizontal 1CM thick lines every so often.. cant take a screenshot unfortunately lol
 
If you are getting screen tears with vsync something is very weird because the entire point of vsync is that can't happen.

Having screen tears on the desktop also shouldn't happen because Windows automatically enables vsync as far as I know.

Have you tried another monitor? Another cable?
 
Big tear like artifacts could be memory being pushed too far.

What card do you have and what settings are you trying to run it on? e.g. core, memory, fan %, temps its running
 
Hi, thanks for the responses guys.

i dont have another monitor/wire to test it at the moment unfortunately.

Hi Andybird123,

my pc is pretty old now, so its embarrassing lol, but i have a HD 5850, its all running at the default so 725, gpu, 1000 memory and 30% fan speed. the temp is 50c average.

it was fine before i attempted to overclock it, i didn't really know what i was doing so i'm worried i messed it up.
 
I have a older viewsonic screen that screen tears in certain games unless i limit the frequency to 56Hz . Oddly this only tears on DVI-D on HDMI its fine I'd guess something is gotten old and weak in the monitor scaler and have learned to work around it
 
ive set the monitor to the highest HZ but it doesnt change anything..

Im not sure if it is screen tearing, let me try to explain lol.

I get a complete horizontal bar about 1cm thick of fuzzy grey shoot down part of the screen every now and then, in different places when it happens. it doesn't just happen in games, it happens on desktop aswell.
 
Doesn't sound like screen tearing so much as artefacting so possibly GPU memory as others have suggested - perhaps got damaged in the OC attempt, or going back to stock didn't correctly set memory speeds back or similar.

Also for reference tearing isnt limited to 'higher fps than refresh rate' - it can happen with lower or equal rates too as it's just the frame buffer getting rewritten part way through the display rendering. At higher fps vs refresh you can have multiple tears within a single frame while at low FPS/high refresh you'll only get one per frame or less, though the difference between frames may be larger thus the effect more noticeable. vsync forces extra buffering to avoid the problem (though this in turn adds lag)

Edit: Changed 'probably' to 'possibly' in reference to GPU memory - could be a few other things as other people have mentioned.

That sounds like some kind of artifact rather than screen tearing. What kind of cable are you using?

If you use some monitoring software, like MSI afterburner, what are the actual reported frequencies. I would make sure the memory is the right speed.
 
Definitely sounds like artifacting, and unfortunately there is a good chance you've done some damage with your overclock.

Well worth trying a different cable first off though.
 
Another thing you could try, is to reseat the graphics card in its current motherboard slot.

If no Joy, then try a different slot.
 
hmm, so i've tried reseating the graphics card, that didnt work :(

i use a DVI Cable by the way!

Its weird, because it seems to only happen ondesktop and not in games :S
