Question about Samsung QE50QN90A

For gamers, the QN90 offers HDMI 2.1 with 4K@120Hz, VRR (Variable Refresh Rate) and HFR (High Refresh Rate).
GQ-50QN90A: With support for AMD's Free-Sync technology, HDMI 2.1 and a refresh rate of 100Hz, your next gaming session is sure to be one to remember.

The web page https://www.samsung.com/de... does not give any direct information, but one can interpret it:
QE: Q = QLED (more precisely NeoQLED, as the QN further back in the name reveals), E = developed for the European market.
GQ: G = Germany, Q = analogue above.
I can recommend the QE50QN90A without reservation.
