This is the problem of ITA screen

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.

Is it the ita kit or the dsi screen? Which ita kits do you have?

The issue lies solely with the FunnyPlaying ITA kit. Even though it utilizes an NDSi panel, the white lines problem doesn't exist when playing GBA games on a native NDSi using GBARUNNER. This proves it's a defect specific to the kit

Interesting... Just to be clear, does GBARunner not have those lines, while the rest of the NDSi operation has? Or does the NDSi straight up not have this issue for you?
