In plain language
VESA defines the display modes computers use. The names are abbreviations rather than resolutions: QFHD is 3840 x 2160, WQUXGA is 3840 x 2400, QUXGA and WQSXGA are other high-resolution variants. Anything within the available bandwidth can in principle be carried.
Why it matters in your setup
PC modes behave differently from television modes in a chain. A device happy with 4K60 may not pass an unusual monitor timing, and a television may refuse a mode a monitor accepts without complaint.
Whether the mode is offered at all depends on the capability data and the preferred timing in it — which is why a graphics card sometimes shows a shorter list of resolutions than the display can actually handle.
What the DR HDMI 8K does with it
The DR HDMI 8K supports all VESA video modes within its 1500MHz bandwidth, including WQSXGA, QUXGA, QFHD, WQUXGA and 4K/8K. Its DTD retention matters here: keeping the display's preferred timing intact is what stops a PC from falling back to a generic mode.
