The converter is basically pretending to be a DisplayPort display (from the perspective of the laptop) with the same specs / resolution / refresh rate as the HDMI 2.1 display which happens to be connecting to it.ĭoes a table exist somewhere that shows you what resolutions and frequencies you can get from DP1.4 over Thunderbolt? What matters is that the Thunderbolt can give DP1.4 signal which is enough for 4K 120Hz, and that can drive the Club3D converter to translate that into HDMI 2.1 outside of the laptop. Any adapters take a DP signal from the Thunderbolt and convert it to HDMI in the chip in the dongle. HDMI is incompatible with Thunderbolt, and the controller never emits a HDMI signal. I have no way to verify I can do HDMI2.1 through the Thunderbolt 3 connector without a lot of expensive purchases. Then the DP1.4 to HDMI 2.1 adapter will terminate the DP1.4 signal and translate it into HDMI 2.1 signal / protocol. The USB-C to DP connector is basically changing the connector, maybe amplifying the DP1.4 signal, but not changing it. Only a DP 1.4 signal is routed through the Thunderbolt connector. Do you happen to know if a passive cable like is capable of or would I need an active cable like your first link? It seems all the 43" monitors don't have HDMI 2.1 so that would somewhat limit my options.ĭoes a table exist somewhere that shows you what resolutions and frequencies you can get from DP1.4 over Thunderbolt? Does it match DP1.4 exactly? This stuff is amazingly hard to search which is why I am asking experts in the thunderbolt forum. I am really stuck deciding whether a 144hz screen is really necessary for me. I am now back figuring out which DP 1.4 monitor would work best for me.

However, I found out the TV has a glossy screen and that is a deal killer for me. The cables you linked might just do the trick. Regardless the laptop says it is limited to HDMI 2.0b on the HDMI connector, but the mobile rtx2070 specs indicate it can do HDMI 2.1. However, when I used a cheap USB C to HDMI adapter on a QHD monitor with HDMI it displayed a signal so perhaps I can do HDMI over Thunderbolt. That means the CX8 OLED TV I was looking at might not be the best fit. Thanks a lot for your advice! Since I posted this I found the schematic for my laptop and the bad news is that only a DP 1.4 signal is routed through the Thunderbolt connector. If you have a Thunderbolt 3 to DP1.4 powered dock then you no longer need the USB-C to DP1.4 adapter. Then there is the case of the Dell XPS 17 9700, where there is a BIOS option to switch which GPU is connected to the Thunderbolt, between the RTX2060M and the Intel graphics. You would either have to find this out the hard way, or ask the laptop manufacturer.

There's a small chance that the Intel iGPU is wired to the Thunderbolt controller, also. Your RTX2070M should support it, but we need to check that your Thunderbolt controller is Titan Ridge or later. Please tell me which laptop you have so I can check. Remember that both your GPU inside the laptop and the laptop Thunderbolt controller have to support DP1.4. Otherwise, here is your USB-C to DP1.4 female adapter:

And it will have the benefit of one-cable docking / charging your laptop, assuming your laptop implements Thunderbolt charging. Most GPUs nowadays which you can put in the eGPU enclosure should have HDMI 2.1. If you must do it, consider an external GPU. HDMI should be treated as a legacy compatibility mechanism for things which normally connect to TVs (like gaming consoles). DisplayPort can only be tunnelled over Thunderbolt because it consists of packets. Unless HDMI has been redesigned or overhauled in recent revisions, it is not packet-based, which severely limits its usability in a modern context. There are a lot of monitors with DisplayPort available. įor the computer to support it, you will needa) GPU which supports DP1.4 and is actually wired to the Thunderbolt controller directlyb) Titan Ridge or later Thunderbolt controller in the computerc) Thunderbolt dock (Titan Ridge or later) supporting DP1.4, or a USB-C to DP1.4 adapter (most are only DP 1.2)īasically every component in the chain must support DP1.4 and that is not a given as the vast majority are still DP1.2.īut for next time, I would avoid any reliance on HDMI. Here is DP1.4 to HDMI 2.1 adapter claiming 4K 120Hz support. HDMI 2.0 (which is common) will not support 4K 120Hz.

Search for Thunderbolt docks or dongles which mention HDMI 2.1. You will need something which converts from Thunderbolt to HDMI 2.1, if that exists.
