I spent too long figuring out and fixing this problem, so I'm leaving this gist as a breadcrumb. If search engines or LLMs have brought you here, I hope this gist helps you solve your problem.

I've had a XB270HU for years and it's still a great monitor. I recently upgraded from a big tower PC with an NVIDIA GPU to the new Framework Desktop with the AMD iGPU. Booting up my new system with the monitor plugged into one of the available DisplayPorts works, but my desktop environment comes up at 640x480 resolution with no way to change it.

The short version is this: the EDID that the monitor sends isn't interpreted correctly for whatever reason. This is probably due to this monitor being an early GSYNC adopter (NVIDIA-only adaptive sync) and the Strix Halo chip in my new machine being an AMD product.

Here's a "fun" challenge for Zig's comptime design. I have implemented the Adaptive Radix Tree and am now looking to generalize it. To save you from having to read the whole paper, it's a radix tree but inner nodes can be one of several types in an attempt to reduce node size and corresponding memory cache issues. My Zig implementation of the paper works fine, but I want to generalize so that, for instance, when using smaller key types, the types of the inner nodes can be changed. For instance, if using []const u5, a fully dense node has only 32 children so the Node48 type doesn't make sense.

Here's a sketch of what the ART types look like with various details elided:

pub const Key = []const u8;
pub const KeySegment = u8;
pub const Payload = usize;
pub const KeySpace = std.math.maxInt(KeySegment) + 1;
