Market hasn't evolved towards higher PPI + refresh rate on desktop sized monitors due to hardware constraints / ignorance of people who don't know the pleasure of higher PPI.
The Q24G2A is probably gonna be the last 24" 1440p 165hz panel with the classic WLED backlight, unless someone decides to implement the new 24" 1440p 240hz panels from China with a custom backlight solution (WLED instead of KSF phosphor)
But from what I last read about, KSF phosphor is applied at LED levels (red fringing during strobing), so the panel itself (24" 1440p 240hz) should be sadly with those red peaks. Meaning it could be a potential eyestrain concern (for unknown reasons to me as of now, I've only seen speculations thrown around)
From what I've seen, most 4k 144hz panels are KSF phosphor or QDEF.
