  • Why video recording with 4K resolution is not that useful on your phone

    Why video recording with 4K resolution is not that useful on your phone

    With a barrage of phones releasing this year amidst the pandemic, we are starting to see a trend of smartphone brands integrating 4K resolution (3840 × 2160 pixels) video recording on entry-level and mid-range phones. A special feature that used to be exclusive to flagships, you can now see 4K video recording on devices like the Redmi Note 9Srealme 6, and the Samsung Galaxy M31. Having this feature on a budget device is pretty cool, but this begs the question - do you actually use it?

  • MHL 3.0 on Sony Xperia Z2 enables 4K video output and 10W charging

    MHL 3.0 on Sony Xperia Z2 enables 4K video output and 10W charging

    Both the Sony Xperia Z2 and Sony Xperia Z2 Tablet were recently revealed at the MWC 2014 but a little known fact remains that both devices are the first to offer MHL 3.0 micro-USB ports. Most smartphones today are just using MHL 2.0 micro-USB ports which are a lot slower. The new MHL 3.0 port allows for 4K video output thanks to a dedicated 75 Mbps data transfer rate (MHL 2.0 only offered 1 Mbps) while charging and providing data transfer as well. Granted, 75Mbps is rather slow compared to USB 3.0 whihc allows up to 600 Mbps data transfers but it is still much better than the current MHL 2.0 standard. Most people probably won't have a 4K HDTV but if you do, you should probably get an MHL 3.0 port enabled device like the Sony Xperia Z2 and Xperia Z2 Tablet as well.
