Without further information on your computer setup it will be difficult to find out why your R7-350 was identified as a laptop GPU and not a Desktop GPU.
It is possible you installed the incorrect driver.
Here is the latest AMD Driver for the R7-350 (Desktop) from AMD Download page: AMD Radeon™ R7 350 Drivers & Support | AMD
If you have a laptop need to know the EXACT Full MAKE & MODEL name.
EDIT: Download and run GPU-Z to see what information it gives on your GPU Card. If possible post an image of the results. Also was this a Used or New GPU card?
Thx for the answer. I ll run GPU-Z. I used open hardware monitor and detect it like r9 -m375.
The driver is the same I used. And reading the info it can be used for both GPU. The graphics manufacturer is Sapphir.
What I think is that they used the chipset of the r9. Im not having any issue, works fine, but is the first time its happen to me
