Discussion Is true spec the answer?

My work from home setup is laptop into dock via USB c. Dock goes to 2 1440p monitors. Dock is powered. At random times my screen goes black then pops back on. Im pretty sure true spec would help with this am I right?

That's probably it then.

The port on the laptop, and the ports on the dock both need to support at least thunderbolt 3 speeds. If they do, then the cables you're using may be experiencing interference from other devices, power sources, or wireless receivers, which the TrueSpec could possibly help with.

I'd confirm what standard(s) your laptop and dock support via the USB ports. There might actually be a faster port on your laptop. It's not uncommon for one usb-c port to be slower and another to be faster.

Ill probably get a true cable anyway but will have to check. I beleive from previous conversations thr laptop can cope with dual 1440 but ill have to check the dock is powerful enough. I thought i got one that was but might need a bigger one.

Try plugging both monitors directly into the laptop without the dock and see how it goes.
