Is it possible to get a full 16:9 ratio over the HDMI output without the black vertical sidebars at any resolution? I mean straight out of the camera without processing. I know the T5i can't do a full-screen 1080i, but stretching or cropping with OBS software introduces some lag that is awkward on Zoom calls.
Note: I tried Canon's EOS WebCam software that uses USB instead of HDMI but the frame rate was way too low for reasonable Zoom calls.
Unfortunately clean HDMI output (without the black bars on both sides) from 700D/T5i isn't possible, I was doing some experiments regarding these black bars, I got promising results, you can see here (first post, the HDMI experiment):
https://www.magiclantern.fm/forum/index.php?topic=25287.0So I think implementing clean HDMI output on T5i is possible and we know where to start, but currently I am unable to continue experimenting, lack of time, sorry.

You're welcome!
When I mentioned 1600x2040 preset, I think here:
There is 1x3 Mode which use full width sensor (1.61 Crop) which is 1736x2214 @ 23.976 FPS 2.35:1 AR you can achieve it by crop_new on 700D, however this mode isn't continuous even with the 240 MHz overclock and 10-bit lossless, you may lower the resolution to 1600x2040 @ 23.976 FPS 2.35:1 AR with 1.74 Crop to get continuous recording ..
To achieve continuous recording you need to use 10-bit lossless, and you need the 240 MHz overclock (with Sandisk Extreme PRO 170 MB/s card)
In RAW video I selected 1600, but when I go to Crop mode V2, I didn't change X resolution, but it says 1736.
Yes, This seems correct, keeping X value to zero will give the default X resolution which is 1736 in grey color.
What bit depth should I select in Crop Mode V2? Or should it be off?
For continuous recording, you need to select 10-bit from "Crop mode V2" , and keep it 14-bit lossless from "RAW video".
At the bottom, it says in yellow that it will record at 64MB/s, 0x5.4MB, 23.982 (49%). Expect around 0 frames at 56.3MB/s.
You will need to use 10-bit from "Crop mode V2" to lower the data rate, also you will need 240 MHz overclock which gives up to 68 MB/s write speed in video mode, 192 MHz is limited to ~55 MB/s maybe a little more which won't give continuous recording in this mode . .
Pressing Menu button twice, the resolution of Crop mode V2 shows 1736x2040 1x3, RAW video shows 1600x2040 1.74x
Yes, this seems correct too, recording at this stage (after pressing Menu button twice) would allow you to record some seconds without corrupted frames, right?
I did low level format in the original canon menu when formatting.
What am I doing wrong? Sorry for the trouble.
P.S.: Would the Sandisk Extreme Pro 170MB/s V30 be a better choice by allowing 240MHz?
P.P.S.: In Benchmark, with SD Overclock at 192MHz I'm getting write speeds of about 54 MB/s...it's on the low side, no?
Everything you are doing is correct actually, but you will need the 240 MHz overclock with 170 MB/s Sandisk Extreme Pro and 10-bit depth from "Crop mode V2" for continuous recording, the 192 MHz benchmarks looks okay too if you did the benchmark in video mode, try running benchmark in PLAY mode, run benchmark and press PLAY button; this should give you ~80 MB/s write and read speeds.
Have you managed to get some clips without corrupted frames in this mode?
