what resolution is it that you can drive with "newer HDMI versions" but you cannot drive with DisplayPort 1.4 w/o DSC? The bandwidth difference is not really that much in practice, and "newer HDMI versions" also rely on DSC, or worse, chroma subsampling (objectively and subjectively worse). I mean, one has been able to drive 5K, 4K@120Hz, etc. for almost over a decade with DP1.4, for the same res you need literally the latest version of HDMI (the "non" TDMS one). It's no wonder that display screens _have_ to use the latest version of HDMI, because otherwise they cannot be driven from a single HDMI port at all. Having monitors that supported its native resolution through DP but not HDMI used to be a thing until very recently.

I understand that this is not a common case, but 7680x2160@240 (not to mention using hdr and to be fair, DP 2.1 also requires DSC then). You can use this to check: https://trychen.com/feature/video-bandwidth https://trychen.com/feature/video-bandwidth

On my computer, I cannot drive my 1440p240hz OLED display with HDR. HDR takes the requirement from 25 Gigabit to 30 Gigabits, just over DP1.4's capabilities: https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&H=2560&V=1440&F=240&bpc=10 https://linustechtips.com/topic/729232-guide-to-display-cabl... Like you say, not that much difference, but enough to make DP1.4 not an option
