2018 Acer Swift 1 SF114-32 HDMI 2.0 4K60Hz output

Mateo620Mateo620 Posts: 97Member Fixer
My SF114-32 is not able to display 4K60Hz even though the Gemini Lake Intel Pentium Silver N5000 fully supports it. If the hardware supports it, can this be enabled via software such as a firmware or BIOS update? or even a graphics driver update? Why would Acer purposely limit the display output?

The max I am able to display to my 4K TCL 43S517 TV using my new Certified Premium HDMI cable is 4096 x 2160 @ 30 Hz. However, at 3840 x 2160p @ 30Hz everything looks much more crisp and sharp especially text. It will not display at 60Hz as supported by the Intel N5000 so mouse movement and motion is not as fluid as it can be.

    Sorry, the graphics card/HDMI port specs, not the CPU specs, are limited to  3840x2160 @ 30Hz. Your system actually surpassed that HDMI spec. Jack E/NJ

    Yes I realize that. Therefore it was a nice surprise sure but 60Hz is supported by the 4K panel and the 1080p panel as is the N5000 SoC.

    I do not understand why this was done intentionally. At what cost savings, pennies? This is such a great computer why would Acer do this to their customers? The hardware fully supports it yet they decided to limit it at the HDMI port? Artificially, why?! If Asus can do it surely Acer can. This is completely separate from the USB-C display output issue altogether.

    This thread was moved and it was intentionally meant as a REQUEST or suggestion idea. I may have worded it incorrectly but I stand by my findings. I am not trying to make duplicate threads as we have already discussed this in my previous thread.

    If you need to delete this thread I fully understand. I am just frustrated about this issue but if its not a useful thread do as you want, I understand.

    This is more like a suggestion to improve HDMI similar to what ASUS does. If you can be more specific on what ASUS model and price point you're comparing to the SF114-32, then maybe you could get more attention by the ACER design team by posting your ideas in the ideas section. https://community.acer.com/en/categories/ideas

    Dear Friends from Acer Community,

    I need a confirmation that this laptop (Acer Swift 1, model SF114-32) is capable to drive a 4k monitor ( resolution of 3840x2160 pixels) at 60Hz through its USB-C port using a cable (USB-C >>> Displayport) like this: https://www.bhphotovideo.com/c/product/1478023-REG/iogear_g2lu3cdp22_usb_c_to_displayport_5k.html

    Did someone find a solution to revert the Acer´s limitation of the HDMI port maximum resolution of 3840 x 2160 @30Hz?

    Thanks in advance.

    Neither the graphics adapter, HDMI port nor  C port support 3840x2160 resolution. Max allowed by the graphics adapter is 1080P. The C port is Gen1 and doesn't support video output. Jack E/NJ

    First of all, thank you for answering my question.
    But as least part of the information you provided is kind of weird!
    As far as I know, the laptop Acer Swift 1 (model SF114-32) is offered with a variety of different CPU/GPU(integrated graphics).
    It may come with processors N4000, N4100, N5000 etc., and some of them are advertised by Intel as being capable of [email protected] output.
    Please check: https://ark.intel.com/content/www/us/en/ark/products/128990/intel-pentium-silver-n5000-processor-4m-cache-up-to-2-70-ghz.html
    So, when you say that even "the graphics adapter ... can't support 3840x2160 resolution", it appears to be kind of misleading; or not!
    Maybe it depends of which processor a specific unit has and not only which version of the hardware ports (HDMI 1.4?, USB-C) were attached (built into) to the notebook.
    Can you confirm that even the model with the Intel N5000 processor can't handle the mentioned resolution (not through HDMI, but over USB-C)?
    I am sorry to come up with a similar question.

    Adding some info to my previous post, according the website NOTEBOOKCHECK (https://www.notebookcheck.net/Acer-Swift-1-Series.214020.0.html) the Acer Swift 1 model has already been produced with Intel Celeron N3060, Intel Celeron N3350, Intel Pentium N3710, Intel Pentium N4200, Intel Pentium N5000.
    And as far as I researched, only the processors N3060 and N3710 were not capable of [email protected]

    I understand what you meant.
    Usually my first resources are also official user guides/manuals or specsheets, but my main goal here was to reach someone who owns one of newer models of the Acer Swift 1 to test its video out capabilities.
    Thanks anyway.
