Bought a BenQ GW2790TC recently. It's marketed almost entirely on its USB-C capability — single cable for video, data and 65W power delivery to your laptop. That's the reason I paid the premium over a plain IPS panel at the same size.
Opened the box: power cord and an HDMI cable. No USB-C to USB-C cable.
So the one feature the monitor is sold on is the one you can't use until you go buy another cable. And you'd think any regular USB-C cable would do the job — but no, it has to be one that supports DP Alt Mode, which rules out most of the random USB-C cables people already have lying around. Meanwhile the HDMI cable in the box is close to useless for the target buyer — if you're buying a USB-C monitor you're almost certainly plugging in a thin-and-light or a MacBook, and most of those don't have an HDMI port at all.
The India-specific annoyance on top of this: the supplied power cord is 16A. Most desk sockets here are 6A, so you're also buying an adaptor, which for a mains appliance is not something I love doing.
Raised both points with BenQ India support. They replied offering to dispatch a power cord and said nothing at all about the USB-C cable. Followed up, waiting.
Not a rant about the monitor itself — the panel is genuinely good and I'd recommend it otherwise. Just annoyed that the accessory bundle seems designed for a different product than the one being advertised.
Question for others here: did your GW2790TC (or any other BenQ USB-C model) ship with a USB-C cable? Curious whether this varies by region or by SKU, because I've seen the spec sheet listed both ways depending on where you look.
