Faint vertical lines in some grey shades : do you see it too ?

Hello all,
I know there have already been topics concerning the G750's screen. I'd just want to know if others are also seeing a pattern of dark vertical lines in some shades of grey or sometimes other dark colors.
It's only visible when you look close to the screen. I have a G750JH (so a 780M) and I am using the stock 311.83 drivers (which are working well otherwise and have never crashed).
I got an AUO matte screen (non-3D).

I tried the 326.80 and 327.23 drivers : with these, the effect seemed different : not really vertical lines, but more a "grid" effect. So I reverted.
Again, it's only visible on some specific colors/shades.
It has, I think, nothing to do with the "other" line problem (horizontal "waves") where people just created a custom refresh rate for the monitor. (for example, I'm at 70 Hz)

Yeah, I have sensitive eyes.

So, is it the screen, the GPU, or the drivers ?

It's a pity I like the screen of my 2005 Dell XPS M170 much more...

Waiting for your feedback.

311.83 : you can see vertical lines if you look closely.


311.83 : "zoom" on a wall. Ok, no vertical lines here.



326.80 : weird "Pixellated" effect.


326.80 : "wall zoom" again : WTF ???? Looks "pixellated", like a 16 bit color palette ???

THAT'S WHY I reverted to 311.83.
327.XX did the same ("pixel thing"), by the way.

Pierre990429, in the extreme magnification I can see the vertical and horizontal screen elements that for all of us blend together when viewed unmagnified..They stand out when magnified, I see that. But, Pierre990429, you are magnifying it way beyond what I would normally even consider - unless I was playing around with my DSLR and a telephoto lens 🙂

I don't have a camera to do the same with my screen right now, but I would be surprised to *not* find something to complain about when magnified that much. Pixel color groups are gonna start showing if you magnify any further 🙂

I went to the page you magnified, and it looks clean at 100% non-magnified size. I tried all 3 ICC profiles to see if changing that would cause anything to pop out, but I see nothing but a clean background image.

Does anyone else see anything odd on their screens at that URL at normal 100% view, or magnified - and how much magnification did it take to make the screen elements stand out?

Sorry it bothers you Pierre99049.... did you check around for a repair shop that can swap screens for you?

With my cheap JW chowmein (or whatever chinese it is) panel, i cant see any of the lines Pierre is talking about. And my vision is beyond great.

Ah, and yes, I have some "banding" in the gradient test, in the "dark greys".

Maybe these lines are only visible on the AUO screen. You all seem to have the Chi Mei ?

Could an AUO screen owner tell what he sees ? (maybe it's geforce 780M related, but I doubt it)

Except for those who "see" the lines. (even without "magnifying" : just looking at the screen)


I just marked the bottom of some lines in red. It has nothing to do with the "space" between physical pixel elements of the screen.

Yes, I'm about to search for a place who could swap screens.
What bothers me, is that there is no official ASUS comment about this.
And I was able to replace MYSELF the screens of 2 Dell laptops, but not this one :
Could anyone tell me HOW I open the bezel? As I said, the back and front plastic parts seem really put tight together.

What did you find wrong with the Dell screens, and what make model were they replaced with?

Do you notice a particular spec in common with screens you don't like (other than the visual one), and something in common with the spec's in the screens you do like?

Please do come back and let us know what you end up doing to fix/replace the screen.

Thanks Pierre990429!

Nothing wrong with the Dell screens, but my Dell laptops are from 2005 and 2008, and one recently got several vertical lines of stuck pixels - common issue with laptop screens, at least LG models - , so I had to replace it (twice, because the first replacement - pre-owned screen - was also faulty - well, much better : had only 1 vertical pink line) .




Dell used very specific screens with each its "inverter". For example a screen of a M1710 won't fit a M170, even though they are very similar models and the connectors are the same. You have to find old pieces on Ebay... These are old screens (16/10 ratio, CCFL back-light, not LED - I wonder if it wasn't better) with a different connector as the actual ones. And there is a power connector.
(yeah, many sellers offer "compatible" screens, but you don't know what you get)
Dell used to ship their models with Samsung or LG-Philips screens. Most people liked the LG ones better. Both were glossy and "TrueLife".
Of course, many sellers offer "compatible" screens, but you never know what you get finally.

But for my desktop (I7 2700K, Win 7 64), I got a Samsung , glossy , SA23A700D, 120 Hz, 3D capable (with DVI-D cable), but I'm only using it at 60 Hz. It's really great. (couldn't find a glossy LG model)

I like glossy screens (otherwise it's like looking through a muddy glass), with sharp and vibrant colors, no flicker, no waves, no weird pattern "in the pixels".


I still didn't change the G750 screen, as I'm not using it much now. (typing this with the old Dell - WinXP)

The http://www.samsung.com/us/computer/monitors/LS23A700DS/ZA monitor looks great, but if you back up to 3D monitors in that site, it looks like Samsung doesn't offer any right now? 0 matches for 3D on US site http://www.samsung.com/us/computer/3d

I wonder what is up with that? New models coming?

Have you tried running 2d at 120hz instead of 60hz? Seems like a big win is waiting for you to unleash...

Please come back and let us know what glossy screen you find for the G750 that ends up fitting/working.

Hmmm, the only 120 Hz (3D) Samsung monitor on the French site is the S27A950D : http://www.samsung.com/fr/consumer/it/monitors/led/LS27A950DS/EN

Available on Amazon.com : http://www.amazon.com/Samsung-S27A950D-27-Inch-Class-Monitor/dp/B004Z75LX0/ref=sr_1_1?ie=UTF8&qid=13...

A bit expensive and too big for me (23" is the ideal size)

My S23A700D is on Amazon US too, but through third party sellers/offers :

http://www.amazon.com/Samsung-S23A700D-23-Inch-LED-Lit-Monitor/dp/B006WAGLGO/ref=sr_1_1?ie=UTF8&qid=...

Or this one : (750D) :

I haven't tried 120 Hz in 2D (but I must have the DVI-Dual cable because few programs - mostly "demos" from scene.org - choose automatically the highest refresh rate declared by the monitor , and with a normal DVI cable, it doesn't work : black screen) : I always have Vsync ON , and I guess it will stress the graphics card less (Geforce 580 GTX - I bought this in November 2011, for Skyrim).
I'm not sure if I would see a difference. And some games (like Skyrim) have something like a stuttering bug if the refresh rate is too high (64 Hz for Skyrim).

Pierre990429, your GTX580 should drive it fine at 120hz in 2D. As for game support, you can limit the FPS for those specific games with high fps/hz issues, but for 99.9% of the games the GTX580 should run many at 120+ FPS. And, like you said your DVI-D seems to be working ok at 120hz 2D, so give it a try 🙂

It may be that Samsung is switching over to new 3D models coming up, and that is why there aren't any listed:
