Inspiron 16 7610, via Thunderbolt 4 on the monitor, charging and transmitting image and sound - feasible?
Hallo, ich besitze ein Dell Inspiron 16 7610 Notebook. Ich möchte einen externen Monitor über Thunderbolt 4 an das Notebook anschließen. Ist es möglich, das Notebook über Thunderbolt 4 am Monitor aufzuladen und Bild und Ton zu übertragen? Hat jemand schon Erfahrungen damit gemacht?

The system ships with a 90W or 130 W AC adapter -- if your system has the former, it can charge and run with a 90W input to the Thunderbolt port. If it has the 130W adapter, it needs more than a single Thunderbolt port can supply. The system may still run on a 90W input but won't run at full speed -- full speed operation requires using the Dell power supply connector and the 130 W adapter.
The overall answer is yes, one Thunderbolt port can both charge the system AND connect for video at the same time -- it's the power input that will be the limiting factor.

Hi ejn63, thanks for your quick reply. My laptop came with a 130 W AC adapter. If I understand you correctly, I will still be able to charge via Thunderbolt 4, but at a lower power (90W). So it will take longer to fully charge my laptop?

Yes, that will be the case. Also note that you'll likely see an error referring to an underpowered DC input, and that the system will not be able to run at full speed on a 90W input.

OK, thank you ejn63 for your support. If it is likely that an error message will appear and the system will not be able to run at full speed on a 90W input, I will consider whether using the Thunderbold port makes sense for me at all.

For charging, it makes sense for systems that need less than the 90W such a port can supply. That's the limit for Thunderbolt 4.
Thunderbolt 5 should arrive soon, so new systems will have a 240W charge power limit -- which will open the possibility of charging higher-performance systems over Thunderbolt much wider.
