G75VX screen flickering

[gokica]

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.

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..?

Yes, it does take a while because the games still use the 60 HZ. As it's not a standard refresh rate (40 or 60 for those screens), the game switches only to what it reads as standard. If you manage to make 91Hz as a standard resolution then it won't take that much.

To see that I am right, take a normal monitor on a PC and select a refresh rate for desktop and another in the game (GTA IV has this option). You will see that it takes a while (1-2 sec) to adapt.
Another way to see this is if you use the same refresh rate but different resolutions in the game vs. desktop. It takes the same amount of time (1-2 sec) until the screen adjusts to the set resolution.

Cheers!

well i cant live with 1-2sec black out since i alt tab all the time from my games...

The "fix" for the flicker is 67.08 refresh rate for the "horizontal refresh rate."
(this is the "native resolution")
If it's not already set to this rate, you should change it!
should look like screenshot below!



Hope this helps guys?

I would try 75Hz refresh rate then!
I have the "Chi Mei 173HGE" panel, and I don't have any of the problems you guys are experiencing.
You guys must have defective panels, sorry to say!
Time to RMA!

No, it's not. Please test with all screen brightness settings (fn+f5/f6) on this site. http://www.lagom.nl/lcd-test/inversion.php#inversion-all.png
As you can see, it still flickers pretty bad. The only manageable refresh rate is the 91Hz fix, which is far from perfect, but it works the best.

The 91Hz fix is only for ChiMei CMO1720 matte LCD screen. Each and every ChiMei 1720 panel has this problem. I had a G74 before. Guess what. Changing the refresh-rate helped. I RMA-d my G74 three times until getting a refund and buying my G75. I had 2 G74's in RMA with mine with the same flicker issue and same LCD panel. The refresh rate trick fixed the issue. (a cousin of mine works at ASUS RMA in Romania and I asked him to do that. He confirmed)

Well if you guys properly calibrate the panel, this is not a issue!
I use "DVE HD BASICS" to calibrate all my LED/LCD panels, and don't have this problem (I'm in native resolution 60Hz).
Thats one of the first things I do when I get a new system!
That site you guys are using is showing what calibrated, and uncalibrated panels look like.
Have you all tried to properly calibrate your panels?

You guys need to try this below!

I realize this is kind of an old thread from 2013. Its 2015 now. I was just looking up more information about my LCD technology and came across this thread.
So I decided to post information about my G75VX if it might help someone...
