Well then, if you suspect XFX to be sneaky bitches, I should refer you to t=
he
page of the actual reseller that I bought my XFX RX 460 from:
https://www.caseking.de/en/xfx-radeon-rx=
-460-passive-heatsink-edition-2048-mb-gddr5-gcxf-148.html
which clearly states: "The 2.0b HDMI port carries a 4K/UHD resolution =
signal at
60 Hz and permits the sending and receiving of encrypted signals using the =
HDCP
2.2 protocol (4K streaming, 4K Blu-Rays)."
And that corresponds well to the many reports of Windows users you find on =
the
Internet that confirm XFX RX460 cards do in fact drive HDMI displays at 4k =
60Hz
also under Windows - or should we assume the Windows drivers to be broken a=
nd
all those users just being "lucky"?
> HDMI 2.0b does not imply 4K@60.
Support of 4k @ 60Hz was the first and foremost feature advertised by t=
he HDMI
licensors as being the main reason for introducing HDMI 2.0! - Here's their
press release from back then:=20
https:=
//www.hdmi.org/press/press_release.aspx?prid=3D133
and a clear statement on HDMI 2.0b supporting 4k@60Hz:

Yes, the GPU board cannot guarantee anything with regards to cabling or
monitors - but how is that a reason for a driver software to keep users from
even trying to use this fundamentally important, reseller-promised,
broadly-reported-to-be-working-under-Windows feature?
Should audio drivers discard LFE channels because some sound card vendor ca=

validate that the user connected a capable sub-woofer to his amplifier...?<=
