USB-A ports do not carry DisplayPort Alt Mode video, and plugging a USB-A to USB-C adapter into a USB-C port does not change that. If you are daisy-chaining a USB-A to USB-C adapter and a USB-C to HDMI adapter, this is why you are seeing no video signal.
I believe that what you need is

If you are trying to connect a 4K monitor, you may want to look for an adapter whose description says that it supports 4K resolution and a 60 Hz refresh rate. That might require an "active" adapter and a separate HDMI to HDMI cable.
