No problem.
Displays, resolutions, framrates, edids are all very complex. And marketing muddies the water!

I've encountered this issue before when using BlackMagic equipment.
What I was plugging into was described to me as "1080p".
Laptop directly into it would work, and it looked like 1080p in windows display management.
Going through BlackMagic SDI converters (SDI is a SMPTE standard protocol, so these boxes went hdmi->sdi, sdi cable, sdi->hdmi, and would only support SMPTE resolutions/timings), the display wouldn't work.
Because the display was VESA only.

I then read a lot about SMPTE, VESA, and EDIDs!
