Re: Opinion: 240hz displays are blurry, pixel inversion
Posted: 05 Jan 2018, 13:33
Forgot to upload these, but if anyone's interested in looking, here are the two displays when I did some comparisons on testufo. The setup was done using duplicate display option in Windows, which locked the 240hz at 240hz and the 165hz at 165hz (confirmed via OSD "current resolution" info on both displays that shows current resoliton + refresh rate). The testufo locked to 165fps, so we have 240hz at 165fps and 165hz at 165fps:
Alienware 240hz
AOC 165hz (Downscaled 1440p to 1080p also to match the resolution of the 240hz. The AOC would look 5X sharper if I left at native resolution and didn't show downscaling interpolation. 123.41 PPI on the AOC vs 89.91 PPI on the 240hz panels also adds to how blurry things look on 240hz panel, so I made my AOC blurry on purpouse to have a somewhat fair comparison to the 1080p @ 24.5".) Native 1440p comparison below:
Here is both side by side, AOC @ 165hz/1440p , Alienware at 240hz/1080p (no downscaling on AOC)
Here is both side by side, AOC @ 165hz/1080p (downscaling on the AOC)
It's very clear to see the 240hz has some odd blurring as I've been arguing the entire thread with people saying I'm delusional. The best spot to look is the white dots in the red ship. On the 240hz you can see they all blur together, whereas the 165hz display they are more separated and pronounced. Look at the little black lines in the red ship are missing on 240hz because they're blurred badly. Look at how the legs are more pronounced on the AOC, on the 240hz smeared and light. Evyerything on the 240hz looks smeared in comparison, even when compared to when the native 1440p is downscaled 1080p.
I don't need any advanced testing on other displays to spot the flaw, when the flaw strains my eyes. All I had to do was look at the Acer for 1 minute and I feel the same strain, and I see the same blurring. I can confirm I've seen the issue on both the Alienware and the Acer, so the thought of having a faulty panel can be eliminated. Unless, I saw 2 faulty panels? I would have really bad luck.
So now you can argue with the proof I've posted above. At the end of the day, they're all the same panel and I think they're all flawed, personally. Call me delusional all you want, I now have proof with the photos above, and there are multiple complaints around the web that share the same details I've been describing word for word,including the Acer. There are complaints about this issue on BenQ, Asus, Acer, Alienware, etc. Anyone can go to the original post and click the links and read them all.
I just think the issue is very subtle and blends in with motion blur and a lot of people don't notice.
