The HDMI Forum is adding to the new HDMI 2.1a specification, in the form of Cable Power.This function should make it easier to use longer active HDMI cables.Cables are supplied with power directly from the HDMI connection.HDMI Forum introduces HDMI Power Cable in an amendment of the HDMI 2.1a specification.With this feature, active HDMI cables can be powered directly from the HDMI connection, without having to connect a separate power cable.This should simplify the use of active HDMI cables, argues the HDMI Forum.The feature allows cables to draw up to 300mA at 5V from the HDMI connection.To use the feature, both a cable and a 'source device' that support HDMI Power Cable are required.HDMI Power Cable cables also receive a separate power connector for use with devices that are not compatible with the feature.According to the HDMI Forum, these will be USB-C or USB-Micro-B connections.Active HDMI cables are mainly used to allow for longer cable lengths.With passive cables from certain lengths stability problems can occur due to signal loss.HDMI Power Cable should make using active HDMI cables as easy as connecting passive cables.What about the HDMI 2.1 bug?[Comment edited by Vaal on June 7, 2022 16:32][Comment edited by himlims_ on Jun 7, 2022 6:51 PM][Comment edited by Jan VP on June 7, 2022 16:16][Comment edited by Dazenet on June 7, 2022 21:19][Comment edited by Martinspire on June 7, 2022 5:42 PM][Comment edited by CyBeR on June 7, 2022 20:18]This item can not be responded to.Nintendo Switch (OLED model) Apple iPhone SE (2022) LG G1 Google Pixel 6 Call of Duty: Vanguard Samsung Galaxy S22 Garmin fēnix 7 Nintendo Switch LiteTweakers together with Hardware Info, AutoTrack, Gasmetaal.nl, Nationale Vacaturebank, Intermediair and Independer forms DPG Online Services BV All rights reserved © 1998 - 2022 • Hosting by TrueTweakers places functional and analytical cookies for the functioning of the website and to improve the website experience.These cookies are necessary.In order to show more relevant advertisements on Tweakers and to show embedded content from third parties (for example videos), we ask for your permission.Embedded content allows third parties to provide and improve services, track visitor statistics, display personalized content, display targeted advertisements, and build user profiles.For this purpose, device data, IP address, geolocation and surfing behavior are recorded.More information can be found in our cookie policy.Below you can give or withdraw permission for each purpose or party.More information can be found in our cookie policy.These cookies are necessary for the website to function and to improve the website experience.Click on the information icon for more information.More detailThis limits the number of times the same advertisement is shown (frequency capping) and makes it possible to show contextual advertisements within Tweakers based on pages you have visited.More detailTweakers generates a random unique code as an identifier.This data is not shared with advertisers or other third parties and you cannot be tracked outside of Tweakers.If you are logged in, this identifier is linked to your account.If you are not logged in, this identifier will be linked to your session, which will remain active for a maximum of 4 months.You can revoke this consent at any time.These cookies may be placed by third parties through embedded content.Click on the information icon for more information about the processing purposes.More detail
