Question USB-C to USB-A Adapter / HDMI to USB Adapter

[Brunck]

Need help to post the thread in the correct list. Please, apologies if it is in the wrong one.

I am looking for a very good USB-C to USB-A (preferably 3.2 or, at least 3.1/3.0) adapter. I understand that the transfer speed in USB-C is higher than USB-A (3.2), so it will low the transfer speed to adjust. Brand, manufacture and model suggestions?

I got an adapter (USB-C as male) that allows me to have 3 connections (female): HDMI (4K, but I do not know the speed or version support - 1.4 or 2.1), USB-A (3.2) and USB-C. All three simultaneously. The computer where I need to use this adapter has only USB-A (3.0) and I tried using and adapter USB-C to USB-A (do not have technical specifications from this adapter), but it did not work. I guess it is because of the transfer speed of the USB-C to USB-A adapter.

For the display, I already have an adapter HDMI to USB-A (3.0, I guess). It is not working well, and I need to replace it, that's why I bought the adapter above.

Syntax:

I'm looking for two things:

1. A very good (very well built, very well manufactured) USB-C to USB-A (preferably 3.2 or, at least 3.1/3.0) adapter.
2. HDMI to USB-A (preferable 4K 60fps, but can be, in worst scenario case, 1080p 60fps).

Both, I am looking for good products.

Guidance and suggestions are extremely welcome.

USB-C comes with a bunch of protocols not found in USB-A, allowing the use of programmable output voltages for charging laptops, video outputs or even Thunderbird.

I'm a bit confused by your description, but if you're connecting a 4K HDMI adapter terminated in a USB-C plug, to a passive USB-C to USB-A converter, then plugging this into a USB-A port on a computer, the PC will probably not speak the same "language" as the USB-C adapter, so the USB-C adapter will fail to respond. I doubt it has anything to do with speed differences.

I've used Inateck USB hubs and adapters in the past, but I'm not sure if they have what you want. Most of their adapters are USB-C these days.

I normally use price as a guide. If a device costs less than $10, it may not be as well built as something costing $40. Look for known good brands.

I'm not even sure if USB-A can support 4K on HDMI. The cheap USB-A to HDMI adapters I can see on Amazon only support 1080p.
