You're referring to the LCD inversion artifacts that are commonly found in TN panels (single-pixel checkerboard / vertical / horizontal lines artifacts). It is an issue of many fast TN LCDs, it doesn't bother me if I am viewing from far enough away, but I understand that many are sensitive to this.nanashi31 wrote:After my 3 month adventure in search for a good 240hz monitor these are my findings and i hope they can help . I started with Asus xg258q and noticed some strange vertical lines that appear when i was doing fast movements in Battlefield. After replacing cable/gfx card and did some research i found out that it was a common problem and it was more pronounced the lower the hz used, witch was true in my case since GTA on PS4 was much worse .It was so bad that i almost felt like i was behind prison bars whenever i moved. So after that i went for the 25 inch 240hz Acer counterpart kg251 with.......same results. Switched to Alienware aw2518h and the same problem , no matter the cable or Amd/Nvidia card. They seem to use a panel from the same manufacturer if i am not mistaken .The only monitor i tested without the issue was LG 27gk750f-b.
I only have one question . Does this problem not bother people that like those 25 inch panels? For me it was a dealbraker for sure and was taking away from my experience.
Also, this issue was present in other recent 144 hz TN monitors . And the only 100% way to avoid it was to go IPS . For me IPS isn't an option since the response time gives me a headache .
It does bother many people -- just not all.
This is indeed a pro of the LG monitor, it's a little bit less prone to inversion artifacts. If you prefer less strobe crosstalk with strobed 240Hz, one may prefer the XL2546 but one prefer less inversion artifact in 240Hz, one may prefer the LG 27GK750-B. This is however, by anecdote only, not from official tests.
Some people are sensitive to flicker. Some people are sensitive to motion blur. Some people are sensitive to low-contrast/color quality. Some people are sensitive to brightness. Some people prefer to sit further away from the monitor (which eliminates their ability to see the inversion artifact). Some people are color blind (12% of population). Etc Etc Etc. Not all humans see exactly the same way.
Very hard to have cake and eat it too, when it comes to image quality attributes of 240Hz. Tradeoffs abound.
