Wide samsung monitor

[mrForce]

I'm using an ultra-wide samsung monitor (https://www.samsung.com/ca/monitors/ultra-wide/ultra-wqhd-monitor-with-21-9-wide-screen-34-inch-ls34j552wqnxza/), which is 3440x1440. That's an aspect ratio of 7x4 (or 21x9 as Samsung puts it, which is an odd way of writing a ratio). Anyways, I'm trying to get it to work on my Ubuntu machine, and I'm using your tool. It generates this code: 3440x1440_60.00.S.txt When I try to compile the generated code, I get this error:

edid.S:175: Error: invalid operands (UND and ABS sections) for `<<'

This appears to be because the ratio isn't defined as one of the XY_RATIO* definitions at the top of edid.S. I looked in the EDID specifications, and it looks like only those 4 (16x10, 4x3, 5x4 and 16x9) are supported by EDID. I feel like EDID should support these sorts of weird aspect ratios, but at a quick glance it doesn't appear to. What am I missing here?
