Did you manage to check if the 120hz is true 120hz with the UFO frame skipping tests? From one of the reviews I saw of the Songren model, there was frame skipping from his model, but that was at 144hz, and many reports saying that its a 'fake' 144/120hz monitor only able to run at 60hz.

Here is the test:

Massive conjob. I was one of those who actually pounced on the opportunity. Thought multiple EDID tables. If this was possible, companies like Asus, Acer will be selling their monitors for 3k+++. I think this is absolutely unethical marketing.

Got the monitor delivered, instantly tested with frame skipping from UFO site and flagged it as a conjob. Packed it, and sent it back instantly.

I managed to get a refund though, no questions asked. So perhaps it was error from their manufacturing side?

Anyhow this monitor can be found on a Chinese website. Exact same design, same stand, same panel. Same complaints about it being a fake 144/120hz too.
