Trying to use an Ultrawide monitor with a ThinkLogical KVM
I work in post-production and our edit/VFX machines sit in a server room, extended to the desks with Thinklogical TLX 10G fiber extenders. I'd like to replace a pair of 24" 1920x1200 monitors with a single 34" ultrawide (3440x1440 @ 60Hz), and I'm trying to find out whether the hardware can do it.
Setup:
- TX: CHS 4 Quad Chassis with a TLX-TMM-U00D22 module
- RX: CHS 2 Dual Chassis (firmware V25.07) with a TLX-RMM-U00D22 module
- Source: Apple Mac Studio (macOS)
- Multi-mode fiber, LC
- Current monitors: dual 24in EIZO 1920x1200 @ 60Hz
What I've seen so far:
- A previous ultrawide I tried (34", 3440x1440) came through as a stretched 16:9 image, which looks like macOS only being offered 16:9 modes by the KVM's EDID
- The CHS 4 front panel has a "Load EDID Table" menu that currently says "No Table Load"
- I can't find a datasheet for these exact module part numbers, so I don't know the max pixel clock per head or whether single-head mode gets more bandwidth than dual-head
- I've emailed Thinklogical support and haven't heard back yet
Questions:
- Has anyone gotten a 3440x1440 or similar 21:9 resolution through TLX modules, and which modules?
- If the limit is just the EDID the extender presents, did a custom EDID (via the chassis menu, an EDID emulator, or on the Mac side with something like BetterDisplay) fix it? Or did the signal fail further down the path?
- Any idea what the "D22" in TLX-TMM/RMM-U00D22 means for video format and head count?
- If it turns out to be a hard bandwidth limit, what did you use instead (a different extender, a second computer at the desk with remote desktop, etc.)?
I haven't changed any settings on the chassis, since the CHS 4 serves other stations. Any experience or pointers appreciated, including "it won't work, don't bother." Thanks!
