hi V.
The Murideo is a great value.
You can also try your current TPG and add a HD Integrator box (this will add HDR).
Yes, the QD is the reference unit, but pricing starts at around $7500.
PS: we sell the Murideo and the QD.
For meters: FYI, JETI has not been supporting the 1201 for video displays for more than 2 years.
I would not be worrying about more than 1000 nits for now, but need to consider in the future and or if doing pro grading on the Sony OLED or DV monitors.
