Hey guys I am noticing a strange artifact on my Asus 1080p LED-LCD

it is like a screen door effect, but it is more like a diamond crosshatch pattern, and it only reveals itself when there is either slight motion of the element on screen, or

and this is the strange part...

when I move my head from side to side in front of my monitor at a distance of about 12 inches, I can clearly see a diagonal crosshatch grid pattern.

what am I seeing, is it a problem with my monitor or something inherant to LED-LCD's?

it seems to be connected to some kind of motion blur, for example when I play Diablo 3, like if there is some gold on the ground and the screen is panning, the "150 gold" or whatever becomes very blurry, its not like traditional ghosting, it's more like a distortion, and its coming from the same diamond crosshatch pattern.

Does anybody have any idea what this could be?

It is a very hard problem to describe. Here are the only other examples of people describing similar problem I could find on the internet >

I can also very faintly detect the pattern when I shift my eyes focus from one side of the screen to the other especially looking at light blue's and grey's.

This is the weirdest visual artifact ever. I know im not going crazy because im sitting here waving my head infront of my laptop and that screen does not exhibit the same faint crosshatch screen door effect pattern thing.

Get a magnifying glass and take a look at your screen close up.

Look like this >>>>>>>>>>>>>? IPS panel. Chevrons instead of blocks. IPS = Goods.

another thing I notice is text isnt really as sharp as i feel like it should be.

For example, on Youtube, the text on my laptops 15" 1280 x 800 screen only uses 1 pixel width for like the letter "i"

But on the 1080p monitor like the 'i' spills over into 2 or 3 pixels even, it isnt like clearly limited to 1 pixel width like it is on the 1280 laptop screen.

Is it because at 1920x1080 the pixels are too small so they make the lines of the letters fill 2 pixels instead of one?

Please let me know if this makes sense. I am not sure if I need to return this monitor or not. Please help guys thanks.

How do you have the monitor hooked up?

What is the exact model?

Are you running native reslution?

Yep cleartype is enabled

guys I think what I am seeing might be something with the way my eyes react to LED-LCD

I am going to go to an actual computer store and look at their screens and see if I can reproduce the phenomenon

hopefully they dont think i am crazy when I stand in front of their LED's and start shaking my head from side to side

Guys - try this for me

Grab the scrollbar to the right, and drag it up and down. When I do that, the scrollbar turns blue, and the diamond crosshatch pattern becomes clearly visible while the scrollbar moves, even around the scrollbar the crosshatch pattern becomes visible.

When I stop scrolling the scrollbar, diamond crosshatch pattern goes away.

Anytime an element on the screen is in motion, a faint diamond crosshatch pattern appears?

I need to know if this is inherant to LED-LCD monitors or if there is something wrong with my monitor. Please help!

So upset. My 2005 Dell 1905FP Ultrasharp looks leagues better and its only 1280 x 1024.

The color reproduction on that monitor is much more pleasant. The screen doesn't produce any diamond crosshatch patterns when in motion. I can stare at it for hours and my eyes dont hurt. Text looks sharp and is clearly defined in sharp pixels, with no blurry edge pixels (very faint blurry edge pixels on the 1080p i assume due to the fact that the pixels are so smallt that text rendering effectivfely takes up 2 pixels instead of just 1 which even effectly halves the resolution of the screen if you think about it, if every element that should be taking up a single pixel is now taking up 2 pixels you dont gave 1920 pixels to work with anymore, you have half that.)

actually im starting to think this is how the monitor tries to handle the motion blur problem

because i plugged my Dell Ultrasharp back in and it was not what i remembered, perhaps I was remembering it better than it was but one thing is for sure the Asus monitor retains sharpness during motion much better than the Dell

it seems to be a trade-off, you can either have a little more motion blur or you can have a bit more screen-door type effect but the image as a whole has less blur too it

I have until October for the return policy so i am going to see if my eyes can adjust to the new monitor

It may be due to dithering (Hi-FRC?). It may only be a 6-bit panel, and dithers alternating frames, and when you scroll or move your head, you can see the dither patterns.

after doing some research it looks like you are right, I am seeing the very faint dithering patterns.

kind of sucks because I already ordered an exchange for the same model monitor and Amazon already shipped it. oh well.

Does anybody know of any sub $200 panels 1080p that don't use 6 bit dithering teechnique that this does?
