Aspect ratio of oscilloscope displays

But the Hantek scope I have has a GUI out of the 1990's (and it's not in Sigrok.)
So I'm working on writing my own.
Yes, it has popup dialogs, but it also has enough hot keys and everything works with the scroll wheel too.
Shown: why you should use pullups on I²C. :P

Interesting! - what model Hantek do you use?

Renate:
It's the HT6052BE, which is entirely different than the more common 6022.

There are so many big cheap 4K displays out there you shouldn't have any difficulty finding one. Even Walmart has quite a selection of them.

It's silly to have a nice 12 bit ADC but not the screen resolution to display it. Especially when there are multiple channels on at once and you don't want to overlap them.

Are you on USB scopes as well?

I like the idea but not the implementations that currently exist. PCIe would probably be a better idea if you want to turn a PC into a scope.

What I'm thinking of is a dedicated appliance that has the front ends, ADCs, and processing logic, but no built in display. Instead, it has HDMI output to connect an external display. Or now that COVID-19 has greatly increased the demand for working from home, stream the display over a network with hardware encoding. (Currently using some Tektronix scopes at work, the remote access feature is very useful but a bit slower than I like, not to mention the web UI for reconfiguring the scope is quite clunky.)
