If you laptop has a AMD APU processor with Integrated Graphics then you must install the driver for the Integrated Graphics which will install the driver also for your HD7400M GPU card.
Your HD74xxM GPU card is not supported with driver updates anymore. The last two that you can install are from 2015 & 2016 but only if you have a laptop with a Intel APU Processor and not a AMD APU processor: https://www.amd.com/en/support/graphics/amd-radeon-hd/amd-radeon-hd-7000m-series/amd-radeon-hd-7490m
The above driver is the same for all HD74xxM series GPU cards.
If your laptop has a AMD APU Processor that uses an older driver than the ones posted above then you must use the older APU driver since it will be compatible with both GPUs in your laptop.
But if you have an Intel APU Processor then the link above is the correct driver to install for your AMD Laptop GPU card.
