Rated 5 out of 5 by Anonymous from Mini Pro 400 Nice compact unit

Rated 4 out of 5 by Originaldiscokid from Love this PC Solid mini computer perfect for most office tasks and light video editing/graphics work. Performance is good and I love the form factor, I install it under my desk for more desktop space. No fans so I have installed a $12 fan under my desk to cool it. This is my second Mini and I'm not sure I'll ever buy another desktop form factor again.

I have an older model HP pavilion touchscreen all-in-one and looking to upgrade (hp 24-b010); can I use the touch screen as my monitor with the HP Pro Mini 400 G9 PC?

Asked by: kcruz12553
Hello. Thanks for your question. Your HP Pavilion All-in-One - 24-b010 computer does not have an HDMI in port that would allow you to use the screen as an external monitor. The HDMI port on your computer can be used for a second monitor.
