Which has the better screen?

The iMac M4. Its 24-inch 4.5K Retina panel is much sharper than the HP's 27-inch 1080p display, though the HP is physically larger.

Which is better for video editing?

The iMac M4. The M4 chip and 4.5K P3 display suit color work better, but 512 GB fills fast, so plan on external storage.

Is the HP worth the extra $70?

Only if you need 27 inches, 1 TB of storage, or Windows. On display and chip, the iMac is the stronger machine at $1,129.00 at eBay as of November 6, 2026.

Both should run for years. The iMac's unified memory cannot be upgraded, and the HP's 16 GB DDR5 can be, which helps the HP age better for Windows workloads.

Can I upgrade either one?

No for the iMac: memory and storage are fixed at purchase. The HP's desktop RAM and M.2 SSD are more serviceable, though HP's warranty terms apply.

Which is better for gaming?

Neither is a gaming PC. The M4 handles casual and indie titles; the HP's Radeon 840M is integrated and weak for modern games.
