CP311 1H C1FS  Date 2019 8/05
I bought 3 of these Spin 11
I used the USB C to HDMI converter to attach to my tv.
My small tv in the other room works fine with the chromebook, I tested this with 2 units with 2 converters in all directions and they work just fine, No problems.
When I attempt to connect to my larger 55 inch TCL tv it does not work, All i get is a blank screen or fuzzy lines when changing the resolution.
I tried a brand now hdmi cable. Also my chromebook 3 works just fine with the larger and smaller tv.
I have no clue why this is not working on the larger tv, yet works fine on the smaller tv.

    I tried all the settings and still got nothing.

    Other than that I have no clue as to why it does not work!

    That may be the difference. The CP311-1H doesn't support 1080p. Do you know if the TCL will auto-accept 720p input? Jack E/NJ

    The tv is a 54.6" TCL 55S401
    I tried a bunch of settings and turned hdmi 1.4 manual and 2.0 manual.
    I get a few settings that show fuzzy video, Nothing is clear. Unsure as to what other settings I can change.
    Maybe the tv model will help you!

    I have never changed the settings for the chromebook 3
    So I would not know what resolution i would need to set it at?

    >>>Extended display on chromebook 3 is 1920 1080 60h>>>

    What I meant was what happens to the TLC external display when you change the Chromebook 3 to 1280x720 instead of 1920x1080? Jack E/NJ
