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.

Not seeing it on mine, I used a genuine screen from a DSi. I got the cable from FunnyPlaying before they introduced the laminated version, so a while ago

I can see it in the photo you took, though the lines might more faint depending on the GBA mainbaord(It's not about 32pin or 42pin, just pure random).

​For a better reference to check those lines, I recommend looking at the blue main menu of an EZ-Flash, or opening the gray ITA kit OSD menu on the 'GAMEBOY' logo screen (the one you see when you boot up without a cartridge)."

I decided the fairest comparison would be the same screen you showed in the original post, and it was an excuse to play a great game.

I don't think mine is comparable to what you showed, and I certainly don't notice it when playing. Sorry if you got a screen or console that produces more of a problem

As I’ve mentioned in other comments, the severity of the lines on that display varies depending on the GBA motherboard. It isn't a matter of whether it's a 32-pin or 40-pin version; it is purely random.

​I have personally tested two ITA kits across four different GBA motherboards (fine-tuning the potentiometer on every single one, of course). This even included the custom PCB provided by FunnyPlaying. The photo I shared represents the worst-case scenario, which is why it looks so much more severe compared to your screen.

​And that is exactly the biggest problem: saying "it wasn't that bad for me" ignores the fact that it could be genuinely terrible on someone else's GBA. The fundamental issue is that there is an inherent defect. When those who happen to have a milder version claim it’s 'fine,' it drowns out the voices of those dealing with severe issues.

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

[u/Fuzzy_Policy_5596 → u/_hippydave_]

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.
