Adding a spectrum display to the TS-590SG is a trivial matter - just add an
SDRPlay SDR Receiver (connects via the DRV port on the back) and use a
simple software setup to configure the SDRPlay to track the radio, acting as
a Panadapter AND second receiver....
I am using a similar setup on my TS-590S (did require a minor "mod" in the
form of a flylead attached before the TX relay, not as simple as the
TS-590SG but not exactly complicated either) and it works EXTREMELY well....
I also have the SDRPlay working with N1MM+ and the Waterfall Bandmap
software - worked like a charm during CQ WW RTTY.
There is a lot of info on configuring an SDRPlay to work with a TS-590SG
available on the web - I use AA6YQ's DXLab Suite for my day-to-day
operation, and his Commander CAT package handles the SDRPlay very well. I
use either HDSDR or SDR-Console as the panadapter display software, but
there are other choices available too....

How many other currently-produced $1500 HF radios have a second antenna port
or RX antenna port? Yes, the Kenwood TS-590SG does, but it doesn't have a
spectrum display.
Icom apparently built the IC-7300 to a price point. Given the other features
included in the radio, there may not have been room within their price
constraints to provide a second or RX antenna port...or a video output for
an external monitor.
Rob Sherwood NC0B gave a talk at the Dayton Contest University about
"disruptive technologies" in which he discussed how SDRs have changed the HF
radio landscape. His presentation talks about the IC-7300 and he estimates
that Icom sold approximately 10,000 IC-7300s in the first year of
availability. Rob also discusses how he has used an IC-7300 in contests.
You can view Rob's presentation at: https://youtu.be/owaaT6u4XkY
As for viewing the spectrum scope on an external monitor, there are two
options:
1. Use Icom's RS-BA1 software (approximately $100). It's a Windows program
that provides full rig control of several Icom radios including the IC-7300.
RS-BA1 can display the spectrum scope on a computer monitor.
2. Use N1MM+. The authors have tapped into the CI-V commands for the
spectrum scope so they can, from what I understand, display the spectrum
scope as an extension of the N1MM+ band scope complete with worked stations
and highlighted spots indicated on the spectrum scope. See
