I did have an Asus PA238Q and a Dell U2312HM earlier and if compare the blb on the three monitors i would say that the backlight bleed was:
- Worst on the PA238Q, there was a bright shining green halo around the whole screen
- The Dell U2312HM had a little fainter blb compared to the S24A850DW but on much larger area, 25% of the screen (lower left quadrant) was blbl
- The S24A850DW has a little stronger blb blob than the U2312HM but only on 5% of the screen (lower right)
