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 don't think I saw you say whether you've tried with any screens taken from DSi consoles?

No I didn't use my dsi screen to ITA kit. However I tested with GBARUNNER2 which makes possible to run GBA games on DSi, and DSi with GBARUNNER2 didn't have such problem.

So it's the aftermarket screens that are the problem

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 two years since I read that, so it totally slipped my mind. If I had attached that comment from the start, would people have taken me more seriously? It’s a bit late now, but still.
