Hello nas777.

As banhien EXPERT Level 20 informed you in his reply, you can definitely have dual 4k monitors connected. According to the datasheet you linked to, 840 g10s have 2 Thunderbolt™4 ports that support DisplayPort™1.4 and 1 HDMI 2.1 port. Documentation on Thunderbolt4 informs us that "One Thunderbolt 4 port can connect up to two 4K 60hz DisplayPort or HDMI monitors through a compatible dock or an adapter. Thunderbolt designated monitors can be connected directly." Since the datasheet shows that you can have 3 external displays on this laptop with the use of a docking station, a triple monitor config will also be possible by using the TB and HDMI ports. Therefore, you can connect 3 external displays without a docking station. These docks are optional (for more efficient and tidy computing).
