Go on. You could have posted your schematic. A pencil drawing is fine.
Or you could have taken an accurate photo of your protoboard. e.g. showing the resistors and different coloured DuPont cables.
A photo of a "switched off" DMM is a bit pointless.
I would assume that someone with soldering skills probably knows how to use Ohm's and Kirchoff's Laws.
What is less obvious is Adafruit's trick of example constructors which omit the LCD_RST argument.
Your Red Display does not have a pullup on RST. Adafruit's Displays do have a pullup on RST.
I have suggested Bodmer's libraries for many TFTs.
But one of the most useful pages from Bodmer is this instructable
There are several Tutorials on wiring your SPI Display. Note that many Tutorials on the Internet are complete crap. e.g. no capacitors, no level shifters, ...
If you are following a Tutorial, please post a link to it. Readers might advise whether it is good or bad.
