HDMI 2.1 can do 4k240 with DSC. The fact is that there's only ONE monitor even capable of 4k240, and there's some issue preventing that specific monitor from doing it over HDMI. The only way that's a Nvidia problem is if it's not enabled at the driver level. Otherwise, that's a Samsung problem.
If the 4090 doesn't have the power to push 4k240 now, it sure as hell won't going forward once games become even more demanding. HDMI 2.1 can handle everything the 4090 is capable of. Should it have had DP 2.1? Yes. But acting like it's holding back the 4090 is ridiculous. People are acting like that one monitor thats having issues is representative of every 4k240 monitor going forward, and coming to the false conclusion that the 4090 isnt capable of it. Once the issue with that specific Samsung monitor gets fixed, this all becomes a non-issue.
Going back to the power issue, it can't even do 4k240 without a shit ton of upscaling and Frame Gen except on older games anyway. The whole issue is ridiculously overblown IMO.
The almost perfect crime fumbled by a bone headed mistake. I love it. You can't make this shit up.
Hope he enjoys what comes next. Bubba won't be so gentle.
