Need help sorting out brightness / PWM flicker on my QNIX QX2710 Monitor

post #1 of 9

Hi there,

Posted this in the club page, but not heard of anything - anyone could shed some light that would be great:

Hey guys,

I need some advice.
Recently I've noticed PWM flickering, which is causing me eye strain.
I read to eliminate this (without any hardware changing in the monitor), I should put the monitor on 100% brightness - I can confirm that at 100% I can't notice it.

However, the monitor is too bright - simple solution: Turn the brightness down via Nvidia settings.
Whilst I do this and it's possible to do, for some reason the Nvidia settings do not work when I enable colour sustainer (as it has a custom ICC profile).

Can someone help me out here as I'ma little confused as to what I should do.

Here are the NV settings:


Colour sustainer:


My colour profile: http://d-h.st/wqd
Name: "DUAL-DVI 2014-03-30 D6500 2.2 VF-S 3xCurve+MTX"

I would like to use the monitor at 5-6 clicks below max brightness, but use the colour profile linked.

Could someone help me out - help would be greatly appreciated! thumb.gif


EDIT: some pics of PWM:

The only solution is to use much brighter room lighting and/or use a bright bias light behind the monitor. Lowering the Nvidia control panel brightness raises the gamma which the ICC profiles for high hz are supposed to correct, which makes using both together 100% pointless if one manages to do so.

A 4000 lumen light used as a ceiling light or bias light should be bright enough to counteract a Qnix/X-Stars maximum brightness (250-300cdm2), but they only work properly with light sources capable of outputting 100w. Example:

That literally makes my room brighter - and I don't want that either.
Surely there's a way of:
1. Max brightness 100%
2. Reducing brightness via NV panel
3. Adjusting Gamma
4. Adding colour profile

Surely?

Or what about a new power adapter - heard that also eliminates PWM?

There are three easy options:

1.) Use brighter or more room lighting which will increase glare
2.) Use a single bright bias light behind the monitor which will eliminate all glare/reflections, increase the displays perceived black depth and negate the high display brightness.
3.) Sell the Qnix and buy a Crossover 2795 QHD (OCN Thread) which is better than the Qnix/X-Star PLS and does not use PWM.

The light I recommend is bright enough to be used with the Qnix at maximum brightness as a ceiling light or bias light. A bias light used by itself likely won't make your room much brighter compared to the light you are currently using. Read about bias lighting here. The monitors logic board controls the back-lighting, and it is not possible to source PWM free DVI boards for the ltm270dl02/06/07 panels since the source (Taobao) for these items only sells the panels and a multi-input board with PWM for an older Philips PLS panel.

I already use a light behind my monitor, as it's easier on my eyes. Sure I could use another type of light, but it's still more light in the room. I find it hard to believe I can't reduce the brightness via NV panel, whilst also wanting to use the colour profile. Or is it something you don't know about, as that's something else.
I can always ask the maker of colour sustainer too - could be something that I'm missing
