PS50C7700 @ 100Hz?

[feiercrack]

hi @all,

i like to drive my Samsung PS50C7700 Plasma TV (T-VALDEUC-3018.1) @100Hz via my ASUS FA17-FA707RRW Laptop (HDMI 2.0b) with an RTX3070. Certified HDMI-Cable attached. Nvidia GeForce Game Ready-Driver is current: 576.52. Windows 11 Pro 24H2 26100.4061 with Windows Feature Experience Pack 1000.26100.84.0

All i got since now is: 75,76Hz, with CRU 1.52 (Custom Resolution Ultility)...

But i always thought, that my TV supports 100Hz?! I am not sure, but i believe that i got 100Hz with my previous, older Rig somehow...
Maybe the TV firmware upgrade to 3018.1 changed some things?

Now that i am not so familiar with CRU, there could be some other settings, to get the 100Hz...

Any ideas? firmware downgrade the TV maybe, or give an USB-C with 1.4 miniDP to HDMI-Cable a chance? ...because I could swear, that there was an Samsung TV Windows driver, which supports 100Hz a long time ago, on Windows 10... But for now, i cant find it anymore -.-

Thanks,

cheers, fc^^
