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.

Those are very helpful workarounds you got there, please keep them coming as you find out what works better(or not).
Thanks!

So far the best thing to do is un-install the "Asus Splendid Utility". You will notice the lines go away pretty much immediately, I have to call the best buy kid tonight be for work so I can tell him so he is not going through all that crazy stuff like him and I initially did to get a fix. For some reason on the G750, that splendid utility starts up , changes the color saturation, and then poof, the lines come on, with out it, the lines do not come, and it looks and acts normal, the way it should. Do not return it, first try un-installing the "Asus Splendid utility". You should notice a drastic difference right away. Be sure and update win8 right away too. And after removing the "Asus Splendid utility", you can go and DL the other vga driver available too. Soon enough I imagine Nvidia will put up new drivers too, so either way we can count on this funny little quirk being taken care of. But I am very certain the Splendid utility is the culprit, since it's removal, my horizontal lines are gone, and I have been enjoying this laptop very much. At least it is something simple and nothing major, I am thankful for that.

Hi everyone.
I just got my G750 JX. I trusted the reviews on that model and the hardware seemed perfect for me.

But after the first minutes with the G750 I realized the quite common "vertical lines" on my screen. It's a pain to look at!
I am willing to return it, as I am so disappointed.

For the ones with similar issues I can post my specs, and what I've done to improve it a little bit (but still it's bad enough to return the G750):mad:

I have the G750JX with AU Optronics Display [Model: AUO219D]
You can use HWINFO64.exe portable to see what display you have

Long testing to improve finished with following results:
1.) increase the refresh rate from 60Hz to 70Hz - picture gets a bit smoother. Lines still there, but let's say more blurry now.
2.) Windows color calibration - increse the gamma - picture gets darker in general. Lines are less noticeable than before
3.) uninstalled Splendid - color temperatures changed, but no differences concerning the lines
4.) reduced brightness to ~75% - again everything is a bit darker, lines are less noticeable.

As mentioned the lines still exist, and I would love to see a solution for it.

A friend of mine got the G750 JH, and has exactly the same display (AU) and the same issues with the vertical lines.

The picture Pierre990429 posted shows it quite well:

Pierre990429 has replaced his screen 2-3x, and is back to the AUO, which I guess is least objectionable to him.

I have the G750JH, and play games, watch blu-rays, and stream video, and I don't have a problem with the screen - I don't see this line pattern. It seems to be a rendering issue that under certain circumstances shows up. I guess I am fortunate that I don't run anything that shows this problem like Skyrim.

chippo, one of the G750JH owners that never had Asus Splendid installed, and had no screen issues, had the screen issues after he installed Asus Splendid and then still had the problems after uninstalling Asus Splendid - Asus Splendid is doing something to the display config that it doesn't undo at uninstall.

chippo did another install of Windows 8.1 from Microsoft media and didn't install Asus Splendid, and chippo says his screen is back to normal - good normal 🙂

Bad screen is somehow software related...

If you are about to return the G750, I would try this and see if it gets rid of the offensive display for you. Don't forget to back up the Asus OEM recovery partitions using Asus Backtracker - you will want to restore to it for return or RMA in the future.

Let us know how it works for you.

Okay, the horizontal lines are gone from the regular displays, like say the menus and tabs, but still, when going into a game, like Skyrim, it is still horrendous. So there is still an issue with this. taking off the splendid utility helped, but in fact did not resolve the issue completely. The only way to get rid of the horizontal lines in Skyrim atm is to use an ENB mod and it's settings. While they are gone on most places in game, they will still show up when there is minimal lighting and the shaders are dark, this is getting on my nerves now, especially considering the amount of money I paid for this thing. So really, I am sitting here wondering what to do, this may not be a small thing after all, this is a gaming laptop, but things look so bad in game I cannot really use it as such till this line crap is dealt with and fixed. It may even be something with the gpu after all, since it only shows up under certain lighting and shading situations now after removing splendid utility. I know a couple other people that got these G750's as well, and they too have the same problem, and they are from other states, so I know it is not some silly isolated problem with a shipment over here. Time to report it to the technical support folks...

Your issue sounds similar to that reported in http://rog.asus.com/forum/showthread.php?20249-Weird-faint-screen-lines-over-everything-on-G75WV-BBK... and http://rog.asus.com/forum/showthread.php?11405-G74-Horizontal-lines-on-screen.

If you connect your laptop to an external monitor or HDTV, do you still observe the lines in the shaded areas of games? If not, it likely indicates a problem with the LVDS cable, its connection, or the laptop display, rather than the GPU, video driver, or Windows software.

What is the make and model# of your laptop display?

Unfortunately, the odds of ASUS Technical Support helping you to resolve this problem are extremely miniscule to nonexistent, judging from the referenced threads. My personal suspicion is the issue involves the LVDS cable in some way.

i think you should uninstall Splendid utility and try again.

Did that some time ago.

I did talk with tech support, and guess what they said to do. They said to "refresh" my system. I figured it couldn't hurt, it didn't but it was a waste of time. Did it do anything? No. I am at my wits end with this crap. And what blows me away, is that it is happening with G750's from stores miles away from each other, and two people I know 2 states over from here have the same issue. So it is not just me. And if I take a screen shot, the lines show up, dosnt that mean it is software related if it shows up in a screen shot?
