Might also need to check what the ports on your monitor support. A high quality DisplayPort cable will probably solve the issue, but make check the spec on the HDMI and DisplayPorts on your monitor to make sure they can support higher the higher bandwidth needed for high refresh rate/high resolution monitors. If your HDMI is only v1.4, but DP is 1.2 or 1.4, definitely use DisplayPort instead.

If you just used an old cable that came with something for free, I would buy a proper cable that supports the newer DP or HDMI specs from someone like KableDirekt.

For bloatware to be a meaningful term, I think it needs to go beyond just some arbitrary percent of users don’t need or use it. For an OS, having baseline apps which are useful across a wide variety of hardware setups and use cases is reasonable, even if they don’t apply in your particular situation. Bloat would be superfluous apps that replicate baseline features or baseline apps that have grown in scope beyond what’s strictly necessary.

Ah yes, going to court, a famously simple and cheap process for getting people to do what you want without torching a valuable business relationship.
