Very slight ripples on 24" Acer when running in 120hz When first switching the monitor on.
Hello,

For the most part my monitor is awesome and works really well in 3d I just have an annoying problem.

Whenever I havn't used it for a while and switch it on and it's set to refresh at 120hz, there is a slight rippling effect (It's like black bands going from top to bottom but not full distrotion of the borders etc).

It gradually dies down after 20 mins until I can't see it, but it used to do that in only 10 mins.

I'm thinking that it could also be affecting my 3d vision preformance.

I don't understand why it gets better over time and not worse; I'm thinking it could be a heat issue?

Any Ideas?

Quick annotation: When I set the refresh rate to 110hz it is instantly better and doesn't ripple.

Thats how an LCD draws the screen from upside down 120/ 1hz / 1 picture .

Still its not good enough (upside down) cause there are some artifacts to combat , and they use the glasses to do this, the glasses arent working like 50/50 opaque / transparent , but some 80 / 20 opaque / transparent / frame.


A DLP projector on the other hand is 50/50 and , gives still frames instead of drawing, but different colors, so 1 hz = 3 picture ( R G B ).

So the advantage here is two fold, 50/50 shuttering, and still frames. Superior technology. Even 720p resolution is something that has more advantages than disadvantages (better fps, looks just as sharp).

I'm not talking about viewing the screen with glasses, I'm talking about the LCD screen itself rippling slightly when looking at it with naked eyes :)

I think you've replied to the wrong thread :P

thats an artifact , cause 120hz TN LCD is a fairy tale.

Thanks for advice MD.

I may as well after I've tested a few things and take a video of the effect so they don't send it back and charge me 50 squid. Might be my video card causing it ...:(

@tritosine
"Are you talking to me?! Are you talking to me?! Taxi driver 1986" - Yes, you are reminding me of the Bing advert. :P

Either that or there's forum cross thread interference going on.

So much to test,

It'd be better\faster to find someone who has a similar PC that I could just connect it into, prob try my mate Mike if he's not feeling too lazy.

Yes , Im absolutely sure about LCD hurting your 3dv perf!

shut up, thats not what he is complaining about at all
nothing is perfect, and this is the best you can do with a small display (not DLP projector or DLP/plasma tv)
what he is complaining about seems like a hardware defect in the backlight invertor/the backlight itself
he should get it RMA'd

The monitor in the first youtube link i doubt are really 3D monitors , if you look at the screen they're 4:3 and not widescreen while rules out all 120hz monitors.

OCB LCD-s would be as good as DLP / plasma for 3d.

TN LCD = "not good"

...I had a 2233rz. I couldnt use that monitor for 20 min, gave it to my parents before I sold it.

Check this out:

[quote]Conventionally,
120Hz LCD driving is not suitable for a 3D display using LC
shutter glasses because of crosstalk due to progressive scanning.
With the 240Hz LCD-TV, however, it is possible to minimize the
crosstalk between the left eye and right eye images by image
processing using twice as many frames as the 120Hz driving
scheme. Therefore, the 240Hz LCD-TV has many attractive
points for the consumer, as it not only provides superior motion
picture image quality, but it can also provide an uncompromised
3D experience using LC shutter glasses.[/quote]


ha!!! Maybe what he sees is one of the progressive scanning artifacts. Similar to the samsung LCD TV's uneven backlight bleed, then the service man comes out, verifies it "normal" gives you a sticker and leaves :D .

that technology is far from being consumer accessible, you have to deal with what you've got.
actually, all they need to do right now for a ghostless experience is to perfect overdrive so that it doesn't overshoot, and maybe uses the next frame as reference as well on how much overdrive to apply, then make that into an ASIC and every display can have near perfect 120hz...
too bad we are still in the experimental stages of 120hz overdrive though, it will take a few monitor releases in order to perfect it
