Bad displays, horizontal lines issue

[C_Geigner]

I bought a G750J last night, went through the motions of setting up and doing all the installs. And when all was done, on all black, grey, and all the shades in between and even some of the darker colors, There are very noticeable horizontal lines. I took it back this morning exchanged it out for another one, and it has the same issue. Very noticeable horizontal lines, I am about to go back again and do another exchange, so I will be on number 3 in less than 24 hours of purchase. Not a good sign, makes me wonder if they all are like this. Even with the nvidia drivers updated, it is still there even more noticeable actually. So, lets see what this next exchange will bring, I wager it will have the same problem.

I can confirm that running a custom 67hz or 91hz best takes care of the "flicker" problem. That doesn't fix the clarity issue many are citing. It is annoying that I need a custom refresh and that the sparkle (graininess) is as pronounced as it is.

I have a ThinkPad x220 with a Matte Screen that is not FHD and it is clear and crisp, so I know nice matte screens exist.

Uninstall the "ASUS Splendid Video Enhancement Technology" helped me, so try give it a go 🙂

G750 JW 765M here- that`s how i solved the problem
When editing some photos in lightroom, i saw some horizontal lines in the shadow areas. Started to search for a solution on this forum, and, doing a clean install of older nvidia driver (had 331,now 326.80), worked for me. It`s not a panel fault,because the lines appeared in screenshots and on external monitor.
Also tested in Metro last light, lines are gone, shadows are more on grainy side,but, on full hd display you need to sit really close to see the dots.
Until new drivers will be released, this is a good solution: try older nvidia drivers

What I have while watching movie or playing Mechwarrior online is straight horizontale line toward the middle of my screen. I tried uninstalling Splendid, upgrading to win 8.1 and getting the latest drivers for nvidia experience, nothing helped. I don't have this problem while on facebook and other stuff like that. only when playing games and wathching movies. Really annoyed witht this, I paid good money to get top quality and I feel like my old 300$ computer is better then this laptop.

Its not like the flickering I saw from a post here. Its really like 1 or 2 lines in the middle. I tried it connected on my flat screen and same thing so I don't think its my screen causing this.

I contacted nvidia tech support and the guy told me to download those drivers : http://www.nvidia.com/download/driverResults.aspx/70740/en-us those are the 331.93 BETA. he told me that it would solve the issue.

Thing I just read here that the 331.93 won't solve it. Damn I am starting to really hate this computer and feel like I should have got the MSi .

Also I get around 35 to 46 FPS while playing MWO. I expected this computer to get more fps than this but I might be wrong.

It could be tearing artifacts. If you don't see the lines except in certain games, try setting vsync on for the game / and in the Nvidia 3d settings for that game (or globally). Tearing artifacts happen when you exceed the 60 hz refresh rate of the screen - like FPS greater than 60.

If you have a Chi Mei screen you can also try setting the refresh to 85-100hz as a custom resolution/refresh rate in the Nvidia Control panel - you can set the Nvida vsync on for the game, but some games are fixed at 60hz vsync.

Try one step at a time and let us know if it helps.

Thanks for the info I will try that tonight.

But while playing the game, I see my FPS are at around 35 to 45 FPS max. not greater than 60

Ah, also uninstall Asus Splendid, and go into the control panel Display, and set your desktop size to 100% on Windows 8.0 or earlier, or move the slider all the way to smaller on 8.1.

If you are only getting 35-45fps, turn off some eye candy, like anti-aliasing - etc - and get your frame rate up above 60 fps. I was thinking you were over 60 fps - you want to run near the refresh rate of the screen - if you raise the refresh of the screen try to raise your fps too.

it is ridiculous... buying a 1800 euros laptop and having those bad lines everytime some dark spots are on screen!!!! Asus should verify the problem and fix it, whatever it is and if it is fixable!! For now I will try the updates that they put out here on this thread but if it doesn't work I will start going through all the RMA ****.... I can't believe this is happening!! And then somebody from ASUS comes to this post just to say that there are many happy users???? Is that it??? Is that how the problem will be treated like????

G750JX 16 Gigs ram with the GTX770m video with 3 gigs ram.
Got it thru Tiger Direct from the US into Canada to get the latest CPU, GPU and hardware.
So far no problems to report.

Running Window 8.1
All the latest drivers and bios update done.
Splendid utility is running.
Video drivers updates directly from NVidia using NVidia GeForce Experience, running 331.82

Stable good screen resolution, colours are good, no flickering and no lines.
Works extremely well with 3D solid modeling software, video applications and my games.

The only hardware change I did was adding an 256 Gigs SSD drive and moving over the operating system to it.
Other than getting used to Windows 8 and how to do my setting.
Good networking capabilities, boot fast and deliver a solid performance for my needs.:):D
