    Hello PC Monitors,

    I set brightness to 100% just now, but also if i drop down digital brightness VIA NVIDIA panel to 0%, the monitor is still too much bright.

    The LG W2442PA does not suffer of PWM problem? it’s WLED like this no?


    The LG W2242PA has a CCFL backlight so doesn’t use PWM in the same way. If you are still having discomfort with the monitor set to 100% brightness and reducing brightness in Nvidia CP then it must be something else causing the discomfort. What settings are you using on the monitor?


    Yes i already dropped down brightness by NVIDIA CP to 0% but it’s still too much bright.

    The disconfort is now, i think, only about brightness because the nausea seems absent after 5 hours full immersion on PC, and i feel a pain that is lower and much different than before, it seems more like “exaust” than “burning”.

    My settings are, now:


    Brightness: 100
    Contrast: 80

    Color: User R: 96 G: 94 B:88
    SmartView: DEACTIVE
    Trace Free: 0 (dunno why)

    Splendid: off
    Eco: Off


    Color Channel: All Channels

    Light: 15%
    Contrast: 0%
    Gamma: 1.00

    Digital Brillancy: 40%
    Tone: 0


    In that case it could still be sensitivity to PWM but also brightness. Even making the sort of adjustments you have (including in the Nvidia Control Panel) the residual brightness will be rather high. You either use full monitor brightness to prevent PWM being used (gives discomfort) or you lower monitor brightness and introduce PWM (more discomfort). One thing I would suggest trying before moving onto a new monitor would be to download F.lux . If you find this more comfortable in the evening (when it activates) it could be partly due to sensitivity to blue light. There is a secondary effect here in that f.lux will reduce overall brightness somewhat as well. Would be interesting to test out anyway.


    That effects you are talking about, was not given by the other LG monitor?

    Because with that, i had never any sort of problem, nor eye fatigue, and i never calibrated it so everything runned as out-of-the-box from first to last day, without any issue.

    I received OK for RMA with full refund, but now the problem is: which monitor can I buy to be safe again, and get back the comfort with good gaming prestations?

    The BenQ PWM-free is also a valuable choise? or you think my problem can be something else?

    I used also a TV, while waiting for this monitor, without any problem (like the LG monitor): LG 32LG5700-ZF (model, readed from tag).

    There are some correlations?


    The CCFL backlights of the LG monitor and TV don’t have the same kind of PWM issue and it has a lower native white point (warmer look, less blue light). I feel PWM is an issue for you but I am also curious whether you are sensitive to other elements of the LED backlights. A model without PWM like the new revision XL2411T is the best option really. The upcoming XL2411Z and XL2420Z also use a flicker-free backlight as nd have ‘low blue light’ presets that may be of interest to you. I know waiting for those may not be an option for you though. Hopefully the flicker-free backlight across a good dimming range on the new XL2411T will be enough.


    I think also, PWM is an issue for me, but this BenQ (XL2411T) is rewieved as “Response time (G2G): 1ms (5ms AMA disabled)”

    AMA is?

    Also, the color quality is less, equal or more than my actual monitor?

    There are some IPS monitors that reach 144 refresh rate (also 120 i think it’s fine), 2ms response time (max) and PWM-free?


    AMA (Advanced Motion Acceleration) is just BenQ’s grey to grey acceleration method, which is explained in the review. ASUS uses ‘TraceFree’. The responsiveness of both monitors is very similar and the image quality is slightly better after tweaking on the BenQ – there is a full comparison between the two here.

    There are no 120Hz IPS or 144Hz IPS models available from the mainstream manufacturers, no.


    So, i shall move on BenQ for better quality, i don’t think reverse ghosting whould be significant enought for stuck me with asus at 100% brightness.

    How can I verify that i’m buying the flicker-free version?

    And, does i need some hack for 144hz? or you suggest me to keep 120hz with lightboost?


    Hi Guys,

    Merry Xmas, by the way ..

    I have been following this thread and was going to send a separate email but my problem may be of interest to others.
    I work from home and we have 2 pcs in my home office that I use mostly for reading / writing documents and web browsing. I am not a gamer, as such. I have been using IIYama LS902UT 19 inch CRTs for ever and they are now aging … Set to 85 Hz refresh and warm colour – all comfortable. I could not run at less than 75 because it gave me nausea and headaches.
    So, last week I bought 2 Viewsonic 23 inch LED VX 2370SMH – LED IPS 6 ms monitors which run only at 60 Hz. After 3 hours I had a bad headache and wanted to throw up. I cannot use them. It took 2 days for me to recover. I am now back onto my CRT and all is OK.
    Reading this thread, it seems that I may be getting a severe reaction to either:
    – IPS
    – 60 Hz refresh
    – PWM
    – Too much blue

    Benq seems to have an answer to some of these issues. I looked at the Benq BL 912 size 19 inch 4:3 model (Good size for word docs etc. since I don’t use wide gaming). It seems to be flicker free (What actually does that mean ??? Is it just PWM free, or what ??), but set to 60 Hz. The next possible option is the
    2411T / TE which runs at 144 Hz which covers the 60 Hz issue and can be set to 4:3. ( I guess it has black bars each side on 4:3, but, OK, sort of. Not ideal, but a solution). It does not seem to have the low blue setting. Then, the 2411Z which has the low blue light setting and 144 Hz and gaming features that I don’t need .. and, then, the 2420Z that seems to be the same as the 2411Zc – as far as I can see ..

    So, based on your experiences, what would you guess could be my issue? My preference would be for the 4:3 Benq BL 912 but the 60 Hz concerns me.
    I haven’t checked where these may be available from but – since I am so desperate, I can ship them from anywhere. (I am in UK on 240 v. a/c ..)
    (Looked at the new OLED but at over £ 5000, I think not …)

    I just hope I can solve this before these CRTs die. Otherwise I shall have no option but to check junk shops for old CRTs again ……………..




    As a further comment – the viewsonic was too bright so ran at 40%. Running at 100% to check PWM effect did not help because I could not look at it that way either …


    @ thesharing

    The new 11T models have a different P/N (printed on the label on the back of the monitor) – see this thread or the review. Have you tried your ASUS monitor using LightBoost? You should also see 144Hz listed as a useable resolution straight off on your ASUS – it’s the same with BenQ. If you are going to be using LightBoost then there is no use for a ‘flicker free’ backlight as the two can’t be combined. As explained in this article making the backlight strobe as LightBoost does introduces its own form of ‘flicker’ but it’s different in nature to PWM. If this troubles you on the ASUS it won’t be different in nature (the flickering) on the BenQ models. I’d recommend sticking to 144Hz or 120Hz without LightBoost if you do get the BenQ for optimal visual comfort without any flicker.

    @ Kamares

    Thanks for posting your problem here, it’s always nice to have these sorts of contributions to the forum and have things answered publically so others in the ‘community’ can benefit. It won’t have anything to do with the panel type (IPS) but there are several differences with the ViewSonic LCDs that could be bugging you. As noted in this article on responsiveness CRTs and LCDs ‘sample’ differently and therefore the refresh rate has a different effect on the image. Specifically typical LCDs like the ViewSonics are not constantly refreshing and use a ‘sample and hold’ approaching – so unlike CRTs there isn’t any ‘flicker’ tied specifically to their refresh rate. As mentioned earlier in this thread some users are sensitive to motion blur and can get a feeling of ‘nausea’ when viewing motion on 60Hz LCDs. Do you feel your symptoms coming on more when watching moving objects on the LCD (could be when scrolling a lot on a web page, moving a window about or playing a game) or could you be reading static text and having the same feelings?


    Thank you PCM2,

    The LightBoost was only a question, i think i’ll never use it.

    So, do you think that BenQ XL2411T have better, worse or same color quality than this monitor? It’s not pretty clear in the comparison.

    Also, how can I be sure that i’m going to buy the reviewed, flicker-free version and not the old one?
    Can you link me a trusted one? I’m from Italy, EU.

    Does standards still differ or i can buy an american monitor without problems?

    Thank you


    Hi thesharing, I’m from Italy too. Flicker free product number for Benq XL2411T is 9H.L9SLB.DBE.


    I found the comparison (you mean this one?) very clear. If you look at the colour quality section and the comments in the conclusion it is clear that things go in the Benq’s favour. That comparison and the reviews really helped me make my mind up. Got a flicker free XL2411T from Amazon back in Nov and have no probs with it. Yeh colour is not great out of the box but using the guidance in the reviews you can make it look nice. I too am sensitive to brightness and flicker but don’t have issues with this Benq.

    Keep up the great work guys and happy near year!
