Well some 1080p screens that can resize the screen with a 1:1 ratio won’t have the issue. The problem is that not many devices can actually do that even though it’s a simple feature. A lot of people probably don’t even pay any attention to whether the lines are uniform, but I guess you’re like me, it just annoys me if they’re not. 😛
Edit: I’ll set up a 240p console on the LG, take a picture of it and share it.
Edit 2: 240p in 5x (1600×1200) with 320×240 optimised mode looks like this up really close:
It looks perfectly uniform to my eyes from viewing distance which is pretty close. Keep in mind that the image was taken extremely close up.
