G75VX screen flickering

I am building this thread upon the following:

http://rog.asus.com/forum/showthread.php?28571-Strange-flickering-pulsing-of-screen-on-low-brightnes...

But I am opening the new topic because it is model specific (G75VX).

This model comes with AUO B173HW02 V1 monitor panel (mate non-3D).

It works great except that I noticed weird flicker in one specific situation:



Owners of G75VX please reply to this thread and let me know whether your screen flickers on the image above as mine.

The flicker is present at native resolution 1920 X 1080 and at default 32bit color.

Thanks.

My question would be has anyone seen this flickering while actively involved in a game or while actively using video intensive software?

Hey man sorry you have the infamous flicker of doom, 2 things, one if your are still within a return period return it. If not RMA isn't going to solve anything typically because they have no idea what they are doing, or even care.
What I did to get rid of my flicker is raised my screen refresh rate in Nvidia control panel to 67 on a older DS72 g75. Its worth a try, it almost eliminated most of my flickering problem, if not try a few other refresh rates higher then 60 a shot. Hope this helps.

@compurocker
World of Tanks garage screen has darkish gray colour scheme, and it flickers slightly on my VX. And yes, the box on the first page of this thread flickers like hell 😞

I'm using my VX for work too, and the flicker is a nuisance. Takes its toll on my eyes, it's headache-inducing. In general the flicker is not there, and it can be reduced somewhat with lower gamma, but for the price I paid for the machine I would certainly have expected better. I hope there is a solution to this, but so far one has apparently not been presented by ASUS.

This is especially annoying because I'm otherwise very happy with my VX.

Guys, I've just tested it on my G75VW (the one with CHI MEI display) the test site with the patterns. http://www.lagom.nl/lcd-test/inversion.php#inversion-all.png. Guess what, even with the 67Hz trick I found out it still flickered.

So... I played around with the refresh rate and did create a 91Hz refresh rate. It's stable, no artefacts, no crosstalk and especially, NO MORE FLICKER. Tested on all of the backlight options: from low to bright.

The screen seems stable till around 100Hz, but only 91Hz does the trick! If you do see artefacts or rather weird coloured ghosting effects, just press ESC while testing the refresh rate.

Here is a simple walkthrough:

Open Nvidia Control Panel ->Adjust desktop size and position and select full screen.

Next, go to change resolution -> Customize -> Create Custom resolution -> Type 91 in refresh rate. Make sure Scan type is set to Progressive and hit test. If all works well, select yes.

* * * After this, there should be a Custom with you creation, above PC list. Select it, press the drop-down list and select 91 Hz with 32-bit Colour depth and hit apply.
Whatever way you manage to create that 66Hz, always do the "* * *" part.


Again, this is to tweak the ChiMei CMO panel, but try it on yours as well. Fingers crossed!

WOW

7a was flickering for me,... changed to 91Hz and they are all displayed with no flickers.

Only thing i notice is that whole picture(Screen) is little more brighter?

Thanks

Guys the monitor is rated as a 60Hz.

91Hz is very high overclock and is dangerous for its health.

Good luck since in either case you will end up RMA-ing.

I still see the flicker but since RMA where I live will last forever I am not sending it back.

You should try to ask of ASUS to change the screen on your laptop by RMAing.

The screen is rated 60 but it can display anything till 100 Hz (at least from my tests). Moreover, the screen doesn't get hot enough to show a problem (the screen's chip is on the bottom of the panel. Mine gets warm-ish, but it's pretty normal)

I have used mine for a day now and there is absolutely no problem. The refresh rate will just use a bit more power from the graphics card (because that is the one that pumps the Hz up).

Regarding the brightness, I didn't notice that, as I am normally using level 6/10 of brightness.

so, in conclusion.. in order to end the screen flicker

g74 owners should set their frequency to 67hz
g75 owners should set their frequency to 91hz

i can see the diffrents with 91hz almost no flicker on a gray wab page i used to check ... before it was big time flicker... also it seems all got this flicker pretty standard for asus monitors lol


EDIT: only problem on 91hz is that when u alt+tab from a game to desktop or from desktop to the game it takes way longer to respond... i mean on 60hz its like instant on 91hz it takes like 1-2sec in that time u will have a black screen in front of ya lol

anyone else seen this problem? kind of annoying isan`t it..?
