Asus G74 screen flicker (dark backgrounds and low brightness)

[380mcn]

Hello everybody.
I have an asus g74 and it seems that the screen flickers with a dark background.
If i put the maximum brightness it won't be visible but as it goes down to the minimum the screen starts to flickers. It is a little annoying since i paid 1600eur (2200$).
I have seen other 3 with the same problem. The place where i got it told me it was the inverter. Is yours the same?:confused:

Regarding this issue i don't have any complaint so far (1week of use)

Best wishes

(i don't know the model in question but mine is the one with the i7 2870, 16gb ram, 2hd 500gb, gtx560m 3gb ddr5, no 3D, full hd)

It may be the dimmer board. It seems to be caused by the way the leds are dimmed, unless there's something wrong with the leds themselves.

i have serious doubts this is an software issue..
i use windows, but i also use the express gate cloud from asus (which is a linux distro) and the flickers is still present.
if they are going to 'correct this with a bios update' IMHO i think they will only increase the minimum brightness level in such a way the flicker will disappear.

I'm sorry but i don't believe asus support regarding this issue!

My latest theory is low grade leds that flicker below a certain voltage. I had a cheap led flashlight start doing that yesterday. Lol Really!

You don't think it's possible that the store lighting affected your perception, of both the brightness and the flicker? I think you have to sit them side-by-side to compare in the same environment.

I'm not dismissing your recollection....I don't think any of us can trust our auditory and visual memory enough to make a precise comparison between sounds or images we see at different times.

(If there are still display models in stores that are running BIOS v201, couldn't you go in and (sneakily) make a copy? 😉 I think either WinFlash or Live Update lets you make a back up of the BIOS....)

You should send yours in and tell them to stop being cheapo with their premium laptops. I hope repair costs cost them 10x what they saved by being cheap in their manufacturing practices and lack of qa/qc. 😛

At least their lack of quality is giving employment to a lot of RMA techs.

I have the exact same issue.. I sent it in for repair, now a month later they send it back to me, say it's fixed and that they have replaced some parts that was faulty.

but when I start it up the FIRST thing I notice is that it still flickers.. I'm calling the place where I bought it from
tomorrow to get my money back.

and I was going to take the computer home to my parents for christmas.
I guess I can scratch those plans now.

Hi Andre.

As you can see from @mrtopaz's #112 post immediately above yours, sending your laptop to ASUS is unlikely to resolve your issue.

@Vulkon's #107 post indicates the issue may be resolved in a future BIOS update:

So I have recieved the e-mail from Asus Support, translanting and quoting:

Such issue has been reported. Please, wait for the next BIOS update.
