I wouldn't mind 1620x912 with black bars but it's stretched (more like squeezed from top to bottom) via HDMI which makes the LV via HDMI useless :/
Etiquette, expectations, entitlement...

Sorry for the late reply
For raw recording you either use mlv_rec or mlv_lite, you can't use them both.
mlv_lite supports lossless compression, so use of mlv_lite is advised. So best to not enable mlv_rec module.
The 1x3 presets are not supersharp, the reason, the data is not saved as 5496x1960 but as 1832x1960 resolution. The sensor does horizontal pixelbinning, 3 pixels become one.
So the sensor does really readout 5496x1960 in pixels, but passes this data on as (5496/3 pixelbinning)= 1832 horizontal pixels x 1960 vertical pixels.
In post, for example in MLV_App, these 1832 horizontal pixels are stretched to the original 5496 pixels for normal aspect ratio.
So 1x3 is not as sharp as you would expect from the resulting resolution, because some trickery is used that is available at hardware level of the Canon camera.
In my experience the free software, DaVinci Resolve from Blackmagic does a really good job for upscaling video. (for free, download the normal version, the studio version is the paid one)
It's not that intuitive to use, but there are a lot of tutorials availabe on youtube.

Unfortunately, this is normal
I couldn't get normal liveview to work in this mode, you could however use ML preview to see what the recording will be like.
You can choose different preview options in the 'RAW video' submenu. It's on the MOVIE tab of Magic lantern menu, highlight the 'RAW video' option and press Q button on camera.
Now the 4th option from above should show Preview, here you can set the option from 'real-time' to 'framing', whith the option framing selected, you should see a low resolution preview of your liveview (it's a little slow in FPS).
Another option, you could switch to 'framing' by doing a half press on the shutter button, while doing half press, you should see a preview.
I like this option, I use the half press to check the framing, and press record button, you can even do half press of the shutter button while filming, to check the framing.

2. Try "Topaz Video Enhance AI v2.0.0" for upscaling. But it takes a lot of time.

Hello
1- 5496x1960 in 1x3 isn't real "5496x1960" it's actually 1832x1960 de-squeezeed to 5496x1960 to get a correct aspect ratio (that's how 1x3 mode works).
You should compare 1832x654 3x3 vs 1832x1960 (5496x1960 after correction) 1x3, now you would notice the more details in 1x3 mode (in addition to no aliasing, less moire).
1x3 mode is the sweet spot between 1:1 and 3x3, if you want the absolute sharpness you need to use 1:1 modes, cropping 1x3 footage in post isn't a good idea, it's more like cropping 1080p footage.
2- Upscale it directly from MLVApp --> in Export settings --> resize. You need to take care of aspect ratio, if you have exactly 2560x1440 MLV and you want to upscale it to UHD, set 3840x2160 in "resize" settings, But if you have for example 2560x1280 footage, and you want to upscale it to UHD, putting 3840x2160 in "resize" would result in correct width, but the height would be stretched from 1280 to fit 2160 resolution (Taller aspect ratio which isn't correct)
You need to calculate the AR manually 2560x1280 upscaled to UHD would be 3840x1920. Not sure why MLVApp doesn't calculate AR automatically, it isn't implemented.
3- Provide a picture how LiveView look like, give a short Sample MLV (you can shorten it in MLVApp from "Cut in & Cut out" tab, 2 frames is enough).
