    Glenwing got a reaction from Hackentosher in Ultra Accurate Alarm Clock   
    It's only about $20 for a clock that synchronizes to atomic standards. Obviously I don't mean buying an actual atomic frequency standard.
     
    Quartz crystals are viable, although cheap 32K crystals generally have tolerance of around 20–50 ppm, which is a deviation of up to about 10 to 25 minutes per year. The utility frequency that you advise against is typically more accurate than this over the long term. You can of course find lower, the first clock I made was based on a 0.5 ppm (15 seconds per year deviation at most) quartz crystal, but you have to know what to shop for. And if you're not into electronics it will be easier and more effective to buy a $20 atomic alarm clock.

    Glenwing reacted to Quackers101 in which is best in oled, amoled and qled?   
    That is why I have some hatred in buying of electronics, generic terms while hiding the "real tech" used. From monitors to others, like how they sometimes hide TN panels since they know some people don't want to buy into it or looking down on it.
     
    When I tried to buy something OLED, they said AMOLED so I asked what is the difference, aren't they the same? And they said it was not OLED... like what?
    Sure some people and stores might not know it themselves, but this is what they encourage and make the experience for consumers worse like the naming schemes for most electronics. Like that is the same monitor? oh... it has a K in it, completely different, but then you buy the same monitor without the K and now they have changed the quality on it, to the K version.

    No, AMOLED means active-matrix, which is the method used to connect all the pixels to the controller (active-matrix TFT).
     
    It doesn't have anything to do with the OLED technology itself (active-matrix TFT is also used for addressing LCD displays). Yes they are separate so you could technically have OLEDs without an active matrix, for like lighting strips or basic 7-segment readout panels, but in the context of computer-type bitmap displays, all OLED displays are active-matrix-TFT as there are simply no other methods of connecting that many pixels to the controller. Whether they say "AMOLED" or just "OLED", they are all active-matrix. So it is effectively redundant terminology. You don't need to specify that a display is "active-matrix OLED"... They're all active-matrix in this context.
     
    Samsung just started saying "AMOLED" instead of "OLED" as a marketing trick to make it seem like their OLED displays had some type of advancement over other competing OLED displays. It would be like if Intel started saying "silicon CPU" instead of "CPU" to make it sound like there's something extra. The only difference is that everyone already knows CPUs are made from silicon, so it wouldn't work there. But not everyone knows that all OLED displays are active-matrix, so adding the useless prefix did work in this case.

    AMOLED is just another term for OLED.

    Glenwing got a reaction from Stahlmann in Can't get XFX RX580 to display at 4k 144hz or 4k 120hz   
    For 10 bpc color this is true, but 4K 120 Hz RGB should be achievable with 8 bpc color depth.

    Glenwing got a reaction from p0tat0stix in Will the upcoming HDMI 2.1 gaming monitors support 4k at 144hz on PC with the HDMI 2.1 port?   
    To clear things up, the short version is this: the highest Supported Format for 4K in the HDMI Specification is 120 Hz. People often misinterpret this to believe that HDMI 2.1 therefore doesn't allow higher than 120 Hz at 4K, because they don't understand what a Supported Format is in the context of the HDMI Specification. I explain in more detail here: https://www.reddit.com/r/Monitors/comments/eipp4h/why_doesnt_hdmi_21_support_refresh_rates_above/?utm_medium=android_app&utm_source=share
     
    The exact same debate happened with HDMI 1.4, with people adamantly insisting that HDMI was not capable of 1080p 144 Hz, because "even though it has enough bandwidth, look the HDMI Specification only lists support for 1080p 120 Hz". But this was demonstrably wrong, and is just a misunderstanding of the HDMI Specification. HDMI is limited by bandwidth only; any arbitrary format is allowed as long as it falls within the bamdwisth limit. This is stated in the first sentence of the video section of the HDMI Specification.

    Glenwing got a reaction from tarsius in G-Sync vs. G-Sync Compatible actual difference   
    Yes. Native G-Sync module monitors use this too, NVIDIA just doesn't like to talk about it. The "1 Hz" is using LFC, though for Compatible they don't include the LFC as part of the range, which is inconsistent but that's how it is ¯\_(ツ)_/¯

    Glenwing got a reaction from Oddvar Ashborn in G-Sync vs. G-Sync Compatible actual difference   
    Both native G-Sync and G-Sync Compatible only work above a certain refresh rate, usually around 30–50 Hz or so due to limitations of LCDs (otherwise flickering is caused). To allow variable refresh rate to continue working below this limit, frames are shown twice, so that for example 25 FPS will simply show each frame twice (50 Hz) but your eye will see 25 frames per second and the G-Sync effect can be maintained down to 0 Hz. This is true for both native G-Sync and G-Sync compatible.
