Case number 230415-002545

I want to buy blade 16 with 13950hx 32gb DDR 5600 ram and rtx 4090 175watt, I don't have it now so don't ask again and again for serial number. My current old gen aero 15 OLED with RTX 2070 max q and 9750h comes with hdmi 2.0 if connected on TV which on the other side is new and supports hdmi 2.1 and gsync 4K 120hz OLED (LG 55CX and LG 55C9 OLED both) is stuck at 60 FPS, I've read it's normal on old technology and won't go over 60 fps over hdmi but I wonder why, my laptop does not support hdmi 2.1 while gsync is activable but doesn't work, there is a problem turning off igp and laptop monitor stays always on no way to disable it  and connecting to external TV looses 20% performance, for example firestrike scores 17500 on laptop and only poor 12000 on TV, i heard because of the video signal passing first to igp and due to monitor, then TV, but loss should be only of 3%, not so high. Now i heard these problems are solved in new laptops thanks to some new Nvidia technologies, one is Nvidia Optimus but there are other 2 technologies for these problems which I don't remember the names now.
-Now i ask does blade 16 uses hdmi 2.1?
-More than 60 FPS over hdmi are guaranteed? Why other laptop are stuck at 60fps through hdmi 2.0 and previous gen hardware?
-do you confirm you have a blade 16 with those above cited specs?
-do you confirm rtx 4090 runs at full 175w?
-Can I use Full RGB colours abd 4K 120hz through hdmi 2.1 bandwidth?
-Direct link to GPU through hdmi 2.1?
-No loss of performance?
-Can i use g-sync? Real g-sync.
-can I disable laptop screen when connected to TV?
-i know of the type c port being a display port that has direct link to dgpu but TV doesn't have a display port. You confirm this?
-in this case would an adaptor display port to hdmi make me sure that when I connect to hdmi it works and I have a real direct dgpu link disable laptop monitor with no loss of performance and quality and can use full RGB colours with that badwithdh  and use 4k 120h g-sync?
