It works with Nvidia hardware (thanks to closed\u2011source drivers and firmware), but the open\u2011source drivers used for Radeon GPUs could not support it because the HDMI Forum did not allow HDMI 2.1 support in open\u2011source code. However, it looks like this problem may finally be coming to an end.<span id=\"more-277219\"\/><\/p>\n<p>The lack of HDMI 2.1 support for AMD GPUs on Linux has been a persistent issue ever since the Radeon RX 6000 series launched, and it continues with newer GPUs. The HDMI Forum, which develops and maintains HDMI, was unwilling to approve support in open\u2011source drivers (the specification itself is not open). AMD actually developed an implementation back in 2023 that the company believed could enable HDMI 2.1 features while complying with licensing requirements, but the solution was not accepted at the time.<\/p>\n<p>Until now, AMD GPU users on Linux could only use HDMI ports in HDMI 2.0 mode\u2014with lower maximum resolutions and refresh rates\u2014and they also lacked HDMI 2.1 variable refresh rate support. The only workaround was using active DisplayPort 2.1 adapters, which often do not work perfectly.<\/p>\n<p>But yesterday, Phoronix reported that the situation may be changing. AMD has begun publishing patches that add HDMI 2.1 implementation to Linux and the AMDGPU driver (the open\u2011source Radeon GPU driver).<\/p>\n<p>The first kernel patches add support for the FRL transmission mode, the faster communication mode used by HDMI 2.1. It enables bandwidth up to 48 Gb\/s and support for 8K displays. This is one of the key features that distinguishes HDMI 2.1 from HDMI 2.0.<\/p>\n<p>One of the patches adding HDMI 2.1 FRL mode support to the AMDGPU driver (source: Kernel.org)<\/p>\n<p>The HDMI 2.1 implementation may include more than just FRL \u2014 potentially it could offer full or nearly full support (except for HDCP content protection, which likely cannot be included in&#8230;<\/p>\n<p><a href=\"https:\/\/www.hwcooling.net\/en\/radeon-gpu-drivers-for-linux-will-finally-get-hdmi-2-1-support\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Radeon GPU drivers for Linux will finally get HDMI 2.1 support https:\/\/www.hwcooling.net\/en\/radeon-gpu-drivers-for-linux-will-finally-get-hdmi-2-1-support\/ Publish Date: 2026-05-05&#8230;<\/p>\n","protected":false},"author":1,"featured_media":241230,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/upoutavka-zaslepka-vystupy-graficka-karta-hdmi-displayport-gigabyte-rx-7900-gre-gaming-oc-16g-630px.jpg","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-241229","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/241229"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=241229"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/241229\/revisions"}],"predecessor-version":[{"id":241231,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/241229\/revisions\/241231"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/241230"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=241229"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=241229"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=241229"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
