Darn, I finally can see the flickering on my screen, it's ever so slight and mostly on black or shady surfaces. I forgot, there's supposed to be something you turn off in NVidia but I forgot what it was..

Also does anyone have a link to the latest driver for Windows 8 64 bit?

It's kind of really bad..

Hmm, lowered to 40hz then back up to 60hz.. and it's gone. Weird. Maybe I cannot see it anymore.. not sure.

Nope, lowered back to 40. I actually can see the difference. 40hz doesn't flicker. Oh well, I don't think 40hz would affect me in any way, right? Would make my laptop last longer on battery too.

Or is there something about using 40hz that I should know about?

40 hz is the refresh rate and it may affect video performance, but more so in gaming than anything else, and that's really only if you're maintaining 40+ FPS in games.

I don't understand completely, though I think you mean if my FPS is ABOVE 40 I'll see a difference. It usually is, yes.. but I'm used to 20fps.

Any other downside? And will there be a fix?

Do you mean the vertical banding? If so sounds like you saw the same thing as me recently, lines appeared i changed my refresh rate then reverted back and they stayed gone?

Long known problem on Chi Mei screens, predates the G750 series, the solution is to set the refresh to 85hz or above - when I had one I set mine to 100hz - some are stable at 100hz, but if not 85hz is fine.

Here is a test page to view to see the flicker, on image 4a/4b, and then you can see it go away when you set the custom resolution profile with 85hz-100hz refresh.

When I move the picture all around, the only flickers that happen is 2a 4a and 2b 4b. ( On 40hz. Still no flicker ingame which is good)

Should I just send the laptop in and get a new screen or something? How would I stick it to 85 hz when 40 and 60 are my only option?

Stop saying 40hz :)

Customize - under the Nvidia pre-set resolutions

If you have a Chi Mei screen, try 100hz first, if it looks good under Test, OK, then Ok, then Apply the Custom setting, OK. Ok? :)

I have an AUO screen so I set it to the AUO recommended 70hz at 1920x1080
