Are they over clocking last year's Samsung panels?

LTM340YP03 -> 1800R -> M340CLZ
LTM340YP04? -> 1500R -> C34F791?
If it is indeed a LTM340YP03 panel model, then 100 Hz is within the part's specifications.

This seems to indicate you are correct.

That model is the only 34" model that has a 1800R curvature.

Yeah, it fits all the info on Tftcentral and that's often directly from the roadmaps.
It says 60Hz on the panel exchange but their datasheet contains only the preliminary spec (P0.0).
It is full of placeholder and TBD values and also the interface timing parameters (including refresh rate) are missing the min and max values. Microboard probably has the approval spec sheet.

Hey Guys, not sure if this is helpful but i came across this forum site which had a few pics and pieces of relevant info on the monitor. Although not in English I just translated using my browser and found it somewhat interesting.

http://quasarzone.co.kr/bbs/board.php?bo_table=qc_user&wr_id=5517

I have been looking closely at this monitor and looking out for any extra info. I currently have a Qnix at 100hz but wouldn't mid an upgrade.

Gotta love the auto translations

Original Text:
지금까지 나온 이정도 스펙의 모니터를 생가하면 충분히 가성비?를 논할수 있지 않을까

Google Translation 1:
The birthplace of the monitor specification yijeongdo out so far would not be enough to talk about the non-singing voice?

Google Translation 2:
If you have a monitor of this specification that has been released so far, you might be able to discuss the caustic rain.

Bing Translation:
Until now, if you have enough this specification came out of the monitor's birthplace might argue that sex ratio?

The million dollar question is :

Is this a 60hz native, overclocked to 100hz by these Korean bandits?
Or is it native 100hz?

If it's native 100, then you should be able to overclock it to 110hz without skipping frames.

If however it's native 60hz, then there should be skipped frames at 100hz.

Surely it wouldn't be skipping frames at 100hz as they have it advertised everywhere. They also claim that it can run 144hz at 2560x1080 so hopefully when people from the other thread get it in, they can test over clocks and hopefully get 110hz without skipping frames. I'm also concerned about the difference from a pls (ips) panel compared to this sva panel and if the colours and blacks will be really noticeably different.

It doesn't appear to skip frames at 100Hz:

In the Tftcentral panel database and articles panel is listed as 100Hz native. But unless the approval datasheet has replaced the 60Hz typ. with 100Hz typ. there's still a possibility it is a native 60Hz boosted to 100Hz (i.e. running at or close to the max. input timing specifications)

Does it over clock past 100hz? (If so any dropped frames with over clock?
