Framework laptop 16 144hz external monitor support

Which expansion port should I use to add 2x 144hz external monitor?

The rear USB-C port on the RX 7700S Expansion Bag Module supports DisplayPort Alt Mode that can probably drive 4K 144 Hz. (The GPU itself is probably not fast enough to drive 4K 144 Hz in modern games, as it’s around as fast as an RTX 4060.)

HDMI, DisplayPort, and USB-C expansion cards on the rear two ports and the left middle port of the main laptop body will support 4K 144 Hz display output from the integrated Radeon 780M graphics. (HDMI may be limited to 4K 120 Hz. AMD’s spec sheet for the 7840HS/7940HS did not specify HDMI bandwidth besides “HDMI 2.1”.)

I’m looking to support up to four external display with the internal monitor turned off. Is this possible using the Framework Laptop 16 (AMD Ryzen 7040 series)? 1080p resolution for all external monitors are good enough for myself doing office work.

This is a good ask. I’m looking to connect 3 1440p 165hz displays to mine. Will it support this?

7840HS/7940HS supports four displays, including the internal one. AMD did not specify the maximum resolution for each when three are involved, but they did specify these as the maximum DisplayPort output.

  • 7680x4320 @ 60Hz
  • 3840x2160 @ 240Hz
  • 3440x1440 @ 360Hz
  • 2560x1440 @ 480Hz
  • 1920x1080 @ 600Hz

The frame rate at which a game is rendered has nothing to do with the refresh rate of the display. The GPU will output 4k144hz just as well in game as on the desktop

The latest HDMI card (3rd gen) only supports 4k60hz (HDMI 2.0b), but supports higher refresh rates at lower resolution

My Steam Deck, which also uses DP alt over usb-c also caps 4k@60, whether it be type-c to dp or hdmi. I wouldn’t be surprised if the FW 16 had the same limitations.

Granted, the dGPU expansion has it’s own video output options that don’t go through usb-c and should be capable of 4k higher than 60hz.

The display output port on the RX 7700S Expansion Bay Module is USB-C.

Welp. RIP

As there is no native HDMI output, that does not matter at all. That only depends on whatever DP-to-HDMI adapter you use.

It’s primarily there as the most compact form of a DisplayPort output. The USB-C format doesn’t hobble the capabilities.

Most likely the iGPU in the Steam Deck that limiting the resolution support, there’s no way it can push enough pixels to game in 4K @ 120Hz.


This makes sense. It’s just a shame because even at lower framerates, higher refresh can be beneficial to reduce ghosting and frame-time/refresh deltas on certain display technologies like VA.

We’ll see what the FW supports when it comes out, I’m glad it’s not a limitation of the standard :slight_smile:

So it’s not working as a DP alt mode, but a direct DP output?

It’s DP Alt mode. The port does USB as well, but only USB 2.0.
