Steam Machine is getting a meaningful boost from the software side, and that change could make it far more practical as a living-room PC. AMD has started adding HDMI FRL, or Fixed Rate Link, to the amdgpu driver on Linux, and that pushes HDMI 2.1 support for SteamOS-based hardware much closer to reality.
That matters because Steam Machine was always positioned as a console-style PC meant to feel natural on a TV. Until now, HDMI 2.1 has been one of the most visible weaknesses in its audio and video setup, even though the necessary hardware was said to already be present.
The key obstacle was never just the port itself. Valve previously explained that newer HDMI formats could not simply be added at will, pointing to limits in open-source Linux driver support and implementation hurdles from the HDMI Forum.
The situation now looks more promising. According to Phoronix, as cited by Ars Technica, the latest amdgpu patch notes show the new HDMI FRL work, and Harry Wentland, SMTS Software Engineer at AMD, said the company has added HDMI FRL to the Linux display driver.
FRL is important because it opens the door to higher bandwidth over compatible 48Gbps cables. With more data available, devices can support higher resolutions and refresh rates, while also enabling features that HDMI 2.0 does not offer, including VRR, or variable refresh rate.
For Steam Machine, the practical benefit is easy to understand. HDMI 2.1 is needed for setups such as 4K at 120fps with HDR and VRR on a TV, which is difficult to achieve if the device relies only on HDMI 2.0.
That does not mean every game will reach 4K/120fps. But for lighter titles, including indie games, that target becomes more realistic, and VRR can help keep motion smooth when frame rates fluctuate.
Why TV compatibility still matters most
Steam Machine also includes DisplayPort 1.4, which offers more bandwidth and can handle output up to 4K/240Hz. But that advantage does not fully solve the device’s main real-world challenge, because most TVs do not support DisplayPort.
For people planning to place Steam Machine in a living room, HDMI remains the connection that matters most. That is why HDMI 2.1 support carries more weight than the raw numbers of DisplayPort on paper.
The technical picture is still not fully settled
Even with AMD’s latest driver changes, full HDMI 2.1 support is not completely confirmed yet. Details such as VRR and Display Stream Compression, or DSC, are still described as unclear.
There is also still an open question about whether the broader conflict between Linux’s open-source implementation and the HDMI Forum has been fully resolved. That uncertainty leaves room for doubt over whether Valve will eventually be able to market Steam Machine with official HDMI 2.1 support.
Still, the direction is clearly favorable. If FRL implementation continues and full HDMI 2.1 support lands, Steam Machine will be much better suited to modern TVs and the features players expect from current gaming displays.
Release timing remains another unknown
Video connectivity is not the only unresolved issue. Steam Machine still has no confirmed release date, and its price has not been announced either.
Valve has confirmed that the Steam Controller will arrive on 4 May with a $100 price tag, but no similar confirmation has been given for Steam Machine. Valve also delayed Steam Machine in February amid an ongoing memory crisis, and when the device eventually ships, its cost is expected to be much higher than Valve’s original plan.
For now, the addition of HDMI FRL to the amdgpu driver is the most encouraging technical step for Steam Machine’s future in the living room. If the work continues through to full HDMI 2.1 support, the device will be in a much stronger position for modern TV setups.
