So, I have an Acer Aspire 5542. It's not an amazing laptop, but it works for what I need it to do.

I occasionally get things telling me that its graphics drivers are out of date (usually games). The problem with this is, from what I can find online, the "ATI Mobility Radeon HD 4200" doesn't actually exist. There's "Radeon HD 4200" and there's "Mobility Radeon HD 4000", but no "Mobility Radeon HD 4200".

My DirectX Diagnostic Tool assures me that's what kind of graphics card it is, as does, well, basically everything on my computer. Did they discontinue it? Did it unleash some horrid evil unto the world and denying its existence is the only way to stop it? Or am I just stupid, and, say, "ATI Radeon HD 4200" is an equally-sufficient driver?

Thanks.

None of the above. You go here > http://support.amd.com/us/gpudownload/Pages/index.aspx and go thru steps 1-4 choosing 4xxx series.

edit: or you could go to acer and download what they have http://us.acer.com/ac/en/US/content/drivers  ...either way, you won't see any improvement as you really don't need to update.
