The Samsung Galaxy A55 has HDR10+ support while the Galaxy A35 does not due to a few key differences between the two models:
Display
- Both the A55 and A35 have 6.6" OLED displays with 1080p resolution and 120Hz refresh rates[1][2]- However, the A55's display is HDR10+ certified, while the A35's is not[4]
- HDR10+ is an advanced HDR format that provides improved contrast and color accuracy compared to standard HDR10
Chipset
- The A55 uses the newer Exynos 1480 chipset[1][2]- The A35 has the slightly older Exynos 1380 chip[1][2]
- The 1480 likely has better display processing capabilities to enable HDR10+ support
Price
- The A55 has a higher launch price of $439 compared to $380 for the A35[4]- The HDR10+ certification is likely one factor justifying the higher price of the A55
So in summary, the A55's more advanced display, newer chipset, and higher price point allow it to include HDR10+ support, while the A35 is limited to standard HDR10. However, the difference may not be noticeable for many users, especially when watching content like YouTube that doesn't utilize HDR[3].
