    Does my my laptop (VN7-791G-78Y8) support 2560 x 1440 at 60hz?


    Hello,

    I posted this at Acer community, but didn't receive much help so I thought I'd post here as well, hopefully I posted in the right category. Anyway, I have been looking to buy a 4k monitor for my laptop, however, I soon found out that it doesn't support 4k at 60hz, only at 30hz since my HDMI port is probably 1.4. I found that out when browsing for similar posts. I looked at the specifications and found out that my VN7-791G-78Y8 has a i7-4720HQ (Intel HD Graphics 4600) which supports a Max Resolution (HDMI 1.4) up to 3840x2160@30Hz (this is the information I got from the Intel website). Full specs of my laptop is here. So 4k monitor is no longer an option. The next best alternative would be a 2k monitor (2560 x 1440). However, I couldn't find a full list of supported resolutions by Intel HD Graphics 4600.

    So my question is: can my laptop (VN7-791G-78Y8) display 2560 x 1440 at 60hz (or perhaps even higher resolution at 60hz)?

    Also, is there a list of all supported resolutions by my graphics card somewhere? Since going to display adapter properties on Windows 10 and looking at "List All Modes" only shows a list of valid modes for current laptop's monitor.

    Any help is appreciated.

    There's not much you can do with Notebooks/Laptops. Right-click a blank area of the screen, click Display Settings and see what is offered, choose the Recommended setting. I've not worked with one yet but there are some available that have choices one or another adapter, usually an option on some models. This page shows the maximum at 1920 x 1080 which is pretty much normal but suggests higher can be gained using an HDMI connection to a larger monitor. Maybe getting a unit designed for Gaming [costlier]?

    I started to think that I might have to stick with a 1080p monitor after all if 1440p at 60hz is not possible. Oh well, thank you anyway.

    HDMI 1.4 supports 1440p at 60 Hz, and above.HDMI - Wikipedia

    I'm not sure what the graphics controller in your laptop is capable of, but I wouldn't be surprised if it could do 1440p.

    It may not be ideal for gaming, though.

    Too bad that you don't have an easy means of testing. (Locally purchased monitor, from a store with a liberal returns policy?)
