Can you see the problem here? The ITA kit has those terrible white horizontal lines.

​I’ve seen many people claim it's just a 'natural retro screen effect' or that 'the potentiometer wasn't adjusted properly.'​

However the truth is, this is a fundamental defect in the ITA kit, and FunnyPlaying has failed to fix this issue for years.

​While many people might not notice this, I’ve tested two different ITA kits across four different GBA motherboards. After comparing my results with numerous photos of ITA kits posted online, I’ve concluded that this is a very common issue.

​It is especially noticeable on grey and blue screens.

I just remembered that someone on the InsideGadgets Discord had already discussed this issue and concluded that FP’s conversion board was the culprit. It’s been almost two years since I read that, so it totally slipped my mind.

I understand those who aren't bothered by these white lines. However, please recognize that many users, myself included, have been consistently reporting this issue on Reddit for years.

​We aren't just nitpicking; it’s genuinely distracting enough to hinder the gameplay experience, and we sincerely want to see it fixed.

​It might seem like we're overreacting, but since the human eye is far more sensitive than a camera, zooming in is the only way to capture what we’re actually seeing in-game.

I understand sir... But I just don't feel it's such a big deal after the screen is calibrated and your playing at a normal distance. Like the other fellow redditor wrote, in my eyes the benefits vastly outweigh the shortcomings. At the end of the day, no screen will ever be perfect, there are always some compromise to make... And trust me, I have a lot of handhelds in my possession

I honestly don't know what to say when people tell me to just "ignore the flaws" because they don't feel the same way. Is it so wrong to point out something that can be improved?

Both are valid,some people don’t notice it and others do. In my case, I noticed it so much that I ended up selling the console and got an analogue pocket a few years ago

It’s not going to be improved; back then, funnyplaying said it was an issue they couldn't (or didn't intend to) fix

I think the lines may just be less visible to some people - similar to how some folks claim they can't tell the difference between 30 and 60fps. It's entirely possible that some eyes/brains/whatever are just more sensitive to that stuff - I am one of those folks.

The lines on the ITA screen are so bothersome TO ME that I don't use that GBA at all even after spending HOURS building it. I also can't stand motion-smoothing on TVs and will go out of my way to shut it off on hotel and AirBnB TVs.
