Tft display for Rasberry Pi

Hi fellow makers,

I’m trying to get a 5.6 TFT diplay to work with me Rasberry Pi. I dont have a lot of experience with this sort of tech so reaching out here for some advice. The screen dosent have an HDMI input so I’ve purchased a couple of boards to see if I can get it working.

The screen in question is this one:-

The manufacturer says that it will work with a Pi. I’ve got a 4B. Ive also purchased the following boards at the recomendation of a few people but havent had any luck putting it together…

If anybody has any experience with this sort of setup and could provide some advice it would be greatly appreciated!

Thanks for reading
