    CAN MY PC SUPPORT 4K?

    I’m wondering if my Intel Core i3-6100 with onboard graphics is capable of running an Ultra HD monitor?

    Dafydd Lewis

    Most Intel Core processors from 2010 on support 4K displays – for basic usage at least. The Core i3-6100 has onboard Intel HD Graphics 530, which can display 4K images and play certain video formats, but will perform poorly when it comes to games. We contacted Dafydd to find out which motherboard was powering his PC – this is critical because the HDMI output may not support 4K at the recommended refresh rate of 60 Hz. Sure enough, his Asus Z170-A only supported 4K output via HDMI at 24Hz. Its DisplayPort connector does, however, support 60Hz, which means he needs to source a 4K monitor with a DisplayPort input to ensure the best possible picture without having to invest in a dedicated graphics card.

    I replaced the internal Fusion Drive in my iMac with an SSD. It has now fallen behind with firmware updates. How can I bring it up to date?
