I'm happy to see that engineers keep pushing the limits of panel technologies. It's a shame that this monitor couldn't have ran at a higher resolution or used a better display technology. Subjectively, can you see the difference between 144Hz and 240Hz?
The last time I had a TN panel was 15 years ago. I should give them another shot, they probably look a lot better today than they did the last time I had one.
I'm using a Dell TN at home. After a little calibration, I think it looks great. Sometimes I notice the shoddy viewing angles and I sometimes wonder if it would look a little nicer with 8-bit color, but I'm satisfied otherwise. If you're in the market for a gaming monitor and you don't have bionic eyes that are sensitive to minor color inaccuracy, I'm sure this monitor would be great for you.
