Yeah, but it won't be about video cards (thankfully).
(FWIW, the issues I am having driving two 4K monitors with an RX 550 exist in both Windows and Linux, suggesting that it's not capable of driving both monitors at full spec. Either I need to dial down the frequency as Russell suggests, or I need a new horsepower card...)
Hmmmmmmmmmmm - - - the card isn't current so finding specs isn't straightforward - - - but - - - - https://www.cnet.com/products/xfx-radeon-rx-550-graphics-card-radeon-rx-550-... gives a possible reason for the problem - - - - (one sales agency lists a 'Resolution and refresh rate' and for an RX6900XT said space is 7680x4320 or an 8k space) the gpu just isn't rated for a 7680x2180 space. Here I have a 7680x3000 space - - - but - - - - I'm running 2 gpus - - - that has its own 'problems'! If I had to rebuild my system (not retaining any monitors) I would likely go to 3 - 4k monitors and maybe 3 moderate gpus or if finances were available - - - seldom are - - - 3 mid-upper end - - - - just checked and even an nvidiia 3090 (brand I will no longer consider) where there are 5 ports yet only 4 monitors are supported and a space of 7680x4320@60Hz - - - so a multi-gpu system is what I would need - - - and it works.
