I am trying to get a recommendation on a tft screen to purchase. I read through a lot of the posts on the display forum and haven't seen anything. I purchased the nextion 4.3 screen about a year ago and never used it, I thought I would use it now but after browsing around I see that I am going to be getting more headaches than resolutions.
I am basically looking to get a tft screen that's at least 4.3" and I can add my menus from the code running on the Mega and not have to deal with a micro card to get my menu onto the screen.
If anyone is using a screen like what I am asking about can you please point me to it so I can purchase one. I am surprised that most of the nice screens that I see out there are for the PI and not arduino. Since I have zero experience dealing with the screens I need a lot of help on this.

I would not be surprised.
A large screen with many pixels is difficult for a lot of Arduinos to update at a reasonable speed.
This is a photo of the GPS that I am developing in my spare time, it uses a 3.5 "capacitive screen with an FT813 chip. It uses a teensy 4 but it could well install a teensy 4.1, since the size is quite tiny as using it in the part rear of PCB

I forgot that the newhaven displays looks like exactly what I need, the problem is I cant find any on amazon and I dont see any other displays that match them.
JohnRandalls,
I would recommend these intelligent displays that are becoming more popular, like Nextion.
The main reason is that they have a graphical controller that will manage the TFT a lot easier than a Mega. To control a simple TFT, you would need a graphical controller, graphic memory (GRAM) for TFT resfresh, ROM for the screens, high speed conections, interface logic, ...
I use Proculus displays because of the software.
You can find it at Alibaba. They have shields ready for Arduino.

I have a Nextion 4.3", but as I was about to start working with it I started to see a lot of negative info about it, like there they are not easy to work with and the lack of support is the problem. I really want to use something that I can find lots of examples for and is quite popular with people out there.
This is really my first time working with touch screens and I don't want it to be a nightmare from the start.
You can also use these screens on normal boards like the "blue pill" F103C8:
F103C8 + NHD FT813 3.5"
IDE: 1.8.13
STM32 Official core V1.9.0 or STM32 Danieleff Core
Library: GD23ZUTX
