If you want to connect the two displays to the same Thunderbolt port, then you need a Thunderbolt 3 to Dual DisplayPort adapter, or a Thunderbolt 3 dock or device with a downstream Thunderbolt port and a DisplayPort or HDMI port. So to prove you have Thunderbolt 4, you need to test with two displays (they don't have to be 4K - we just need to verify that there are two separate DisplayPort connections to the Thunderbolt controller). The review that pointed to ( ) shows that the "Thunderbolt 3" text is expected. Basically, like said, if the ports can do all that is expected of Thunderbolt 4, then they are Thunderbolt 4. If the manufacturer says you have Thunderbolt 4, then that means you should have a Thunderbolt port that can drive two 4K 60Hz displays and it can drive a 8K display (but not both of those at the same time), and can do 40 Gbps Thunderbolt with something like 24 Gbps of PCIe tunnelling, and it can do USB4 (but I don't know of any USB4 devices that are not actually just Thunderbolt/USB devices).
HP SPECTRE 15 THUNDERBOLT 3 DRIVER SOFTWARE
The fact that the Device Manager or Thunderbolt software or whatever says Thunderbolt 3 doesn't matter.
They might use a JHL8040R or JHL8010R retimer but retimers don't appear in Device Manager.ĭevice ID 9a1b is an indication of Thunderbolt 4 as that is what is supported by Tiger Lake. It has two downstream Thunderbolt ports and two DisplayPort inputs.ĬPUs with Integrated Thunderbolt (Tiger Lake, Ice Lake, or Apple Silicon) don't need a discrete Thunderbolt controller. JHL8540 (Maple Ridge) is for Thunderbolt hosts that don't already have integrated Thunderbolt controllers. JHL8440 (Goshen Ridge) is for Thunderbolt peripherals (have one upstream Thunderbolt port and three downstream Thunderbolt ports). As you can see: itsage`s build (featuring a Spectre as well) is supposed to have TB4 as well andreads out TB3 in Controll centre (first picture after the headline: Installaiton steps) -> ģ.) If it really is TB3 only - will you miss any of the TB4 features?! As far as I can see, they are somewhat specific and mostly seem linked to other features the device has to have in order to call get the TB4 certificate. Lenovo claimed that my c940 15" would feature charging through TB3 which is not the case.Ģ.) (and I guess, that`s the case) The Thunderbolt control centre might not recognize TB4 or read TB4 incorrectly. HP home page calims TB4 still some magazines describe the Ports as TB4. Still I have 3 ideas:ġ.) Your Laptop might not feature TB4. I do not know much about the supposed configuration of said Spectre.
