I was hoping some people could guide me towards a KSF free monitor.
For the past 3 weeks I have been trying out AOC 24g4x and it has been absolutely killing my eyes and giving me a massive headache. I talked to some people and they said it might be the KSF Phosphor. I had the same issue a few years ago when I tried a monitor with PWM and also had to return that.

I’ve been recommended the AOC Q24G2A which PCMonitors has confirmed has no KSF phosphor or PWM.
However this is a 1440p monitor and I have a feeling it might get too small as I’m used to 24″ 1080p monitor and would like to stick with this.
I assume the 1440p monitor will look like s**t if I simply put it to 1080p so I reckon it’s probably better looking for a native 1080p monitor.

Is there anyone who has any recommendations for a good monitor of 144hz+ that fits these requirements? Price range should be around 150-200 euros.

Thanks a lot

Hi Cromwel,

An LCD monitor these days is pretty much always going to be using KSF phosphors unless it uses a QD backlight solution or has a standard colour gamut (~100-110% sRGB or below). The manufacturer will sometimes market ‘Quantum Dot’ because it sounds cool and MSI includes “QD” in their model codes, but It can be tricky to work out whether QD LED backlighting is used in some cases. Although it’s rare and in the price range you’re considering unheard of (certainly for IPS models).

How well QHD models handles FHD varies between different models and depends on the interpolation process used. The Q24G2A is very poor in that respect. Either way, if you’re happy to stick with the FHD resolution (and this suits your budget well) then there are quite a few standard gamut options. The best of which with is, in my opinion, the BenQ EX240. You might enjoy its well-configured Low Blue Light (LBL) settings as well. This doesn’t all guarantee you’ll find the monitor comfortable as there are many factors to consider. Hopefully the main issue for you is a spectral sensitivity to KSF, though, which will be resolved.

Thanks a lot for the answer PCM. A few people did mention that monitor to me.
Sadly the EX240 monitor doesn’t appear to be available in my region. Only the EX240N has availability, and from what I can tell it’s not at all the same monitor.

I also appreciate your input that it could be many factors, and that is very true. For now I just want to try a monitor without KSF to see if that is actually what’s causing it. I just don’t see it getting any better now that it has only gotten marginally better after 3 weeks.

Could you perhaps elaborate what I should be looking for in a monitor to make sure it isn’t KSF?
Is it just sRGB color gamut under 100%? Or if they specifically mention QD backlight?

[PCM2]

KSF phosphors are used to give a wide colour gamut on an LCD monitor, with QD LED backlights being an alternative method to achieve a wide colour gamut. So you avoid them with a QD LED backlight or if the monitor doesn’t have a wide gamut in the first place (sRGB gamut <110% sRGB should be standard WLED without any KSF enhancement).

KSF phosphors are used to give a wide colour gamut on an LCD monitor…

More like semi-wide.
KSF backlight panels like those from LG struggle to meet DCI-P3 in greens and fall clearly short of AdobeRGB in green and cyan.
Such ironical that LG has devolved from panels they made 10-15 years ago…

KSF phosphors of LG also had at least earlier different decay/fade speed for different colours, which causes artefacts with black frame insertion.
Hence most LG panel using monitors not using BFI.

Yes. Wide(rthansrgb) gamut and red fringe cringe. A winning combination. 😉
