    Would screen tearing harm a display?

    Hey, all. I'm not very tech-savvy, so I was hoping someone a little more advanced with this sort of thing could help me out.

    I've been playing some semi-graphic intensive games on my Macbook Pro, and I've found my hardware is in that uncomfortable valley where it can easily push 60 FPS with VSYNC off, but there's some minor-to-moderate screen tear.

    With VYSNC enabled, however, it slows to an unbearable 30 FPS.

    The screen tearing, to me, is hardly noticeable and doesn't really bother me. At any rate, I prefer it to 30 FPS, so I keep VSYNC off, generally.

    That said, I want to make sure the screen tear isn't going to harm my display over time. This may be an absurd question, but I'm not really sure what makes this hardware tick, (though I've ascertained it isn't voodoo) so... Help a scrub out. :)

    Thanks in advance.

    Screen tearing won't break your LCD, tearing anything else might though.

    However, normally turning on Vsync lowers temps because the GPU isn't rendering frames your LCD won't even display since it waits to draw the entire screen and then outputs it instead of you getting half a frame here and half a frame there, and that might save your GPU in the long run.

    Screen tearing won't hurt your display, but tearing your display will hurt your screen. ;)

    Screen tearing is just the graphics card misaligning the image due to high framerate and most notable when there is alot moving across the screen. It's completely normal. The LCD is just displaying what the GPU is sending it.

    Screen tearing will harm your display. That's why you need to wipe all the tears before your display gets corroded by salt.

    Rubbish, tears are sweet just like Skittles. That's why kids always cry because they often crave for sweet sugary products, such as Skittles with Liquorice flavor.... hmm hmm... Skittles, Taste The Rainbow.

    To expand on this: There's a part of the memory that gets read and put on the screen to make a display. When that bit of memory is updated halfway through the process of putting it on the screen, so part of the image is in the previous state, and part of it is in the later state.

    When in that context, you can see why it's not harmful for your machine ;)

    get a program to force triple buffering. It gives you vsync without the drastic framerate drops.
