ASUS TUF 3080 (1) CTD (2) UEFI logo unable to be displayed on LG 27UL850

My PC

i7-9700K (no OC)
Gigabyte Z390 I AORUS PRO WIFI
G.Skill Trident Z DDR4 4266 19-19-19-39 8GBx2 (XMP)
ASUS TUF 3080 vanilla
LG 27UL850
Club3D HDMI 2.1 cable
Corsair SF750 PSU

(1) CTD

Yes. TUF 3080 has 60 MLCCs. But it does CTD.

I bought the TUF 3080 on release day.
It CTDs frequently when I play Dragon Quest XI on 4K resolution.
I updated GeForce driver to 456.55 and 456.71. But it still CTDs.

I temporarily resolved this CTD problem by downgrading my RAM to another pair of DDR4 4000 19-25-25-45.
If I OC the DDR4 4000 19-25-25-45 RAM to DDR4 4000 18-18-18-38, it CTDs again.
But if I don't use TUF 3080 but another RTX2080 graphic card, it doesn't CTD even I use DDR4 4266.

Can ASUS help me to improve it?

BTW, I used GPU-Z to monitor the TUF 3080's CTD behavior.
When I used DDR4 4000 19-25-25-45, GPU clock was never higher than 1950 MHz.
But when I used DDR4 4000 18-18-18-38 or DDR4 4266, GPU clock attempted to reach 2025 MHz randomly.
When it succeeded reaching 2025 MHz, CTD happened.

(2) UEFI logo unable to be displayed on LG 27UL850

Everytime when I connect to LG 27UL850, it can't display motherboard's UEFI logo.
But if I use the same cable to connect other monitors, it displays MB's UEFI logo properly.
If I use other graphic cards or Intel UHD630 to connect to LG 27UL850, it displays MB's UEFI logo properly too.
So I think it is just an exclusive issue between ASUS TUF 3080 and LG 27UL850.
LG doesn't provide any firmware update about it.
Will ASUS have a solution?

Just found that the LG 27UL850 UEFI logo issue still happened with the latest 0dB fix VBIOS.
