Display is much smaller than screen

[Paula Bekker]

Hello,

I bought an industrial 42" PC screen recently and a new computer as well. Unfortunately when I turn on the computer it only displays as a 15" screen rather than 42" as it should

I have a HDMI cable plugged in and bought a graphics card but neither have solved the problem. The screen is made by Winmate and was purchased off ebay. The seller assured me that it worked "fine" for him and showed a full screen and was very unhelpful.

I can provide screenshots once I get home.

Thank you so much in advance.

What is the link to the screen you bought?

Did you install the video card driver?

Does the screen have a driver?

I just installed a new 24" monitor and at 1080 res the desktop was smaller than screen and blury​

I tried updating drivers etc.. but couldnt figure it out at first?
It turned out to be a 'scaling options' setting in the control centre for my radeon gpu!!
Dont know if this helps?​
