The Korean monitor renaissance has started again? Also check out the 2795 QHD which over-clocks to at least 96hz. The 2795 QHD has brightness controls, but does not have a menu system and only works with PC's via Dual-Link DVI.
Update: Crossover has replaced the 27S with the 27V which appears to have the same features (40-60hz AMD Free-Sync or Native 75hz with Nvidia) but a different case. The Crossover 27 Fast 144 seems to be an Asus MG279Q equivalent with a 144hz native refresh rate, 30-90hz AMD Free-Sync but slightly slower pixel response times and lower contrast than the Asus MG279Q.
Update 2: Crossover replaced the 27V with the 27VV which appears to have the same features (40-60hz AMD Free-Sync or Native 75hz with Nvidia), and the same casing.
Crossover 27VV: 75hz (Nvidia) or 40-75hz AMD Free-Sync
The 27S (the 27V & 27VV likely offer the same performance), 27100Q and 27 Fast 144 are Flicker Free, can be considered delay free (3-5ms delay measured with the SMT Tool by Playwares), use AHVA panels (AUO's version of IPS) and AH-IPS panels (2700Q), have fast pixel response times, excellent color presets and support AMD Free-Sync (assume 40-75hz or 30-90hz with the 27 Fast 144) or 75 (27S, 27V & 27VV), 100hz (27100Q) or 144hz (27 Fast 144) when connected to Nvidia cards. It might be possible to increase the Free-Sync range with the mod mentioned in this thread.
INPUT LAG:
Left - Crossover 27S Freedom (via DP), Right - BenQ XL2420T (via HDMI).
I really surprised, that my gaming TN monitor slower in this case. I can't even expect this result!
75hz:
Maybe I'm doing somethig wrong, but I create custom resolution with 75hz, split test area in 13 blocks (1000/75)... and there is no frame skipping at all.
Chroma 4:4:4:
Only one strange thing. After running input lag test for ~3 minutes and closing window with this test, at the place where they were digits I notice blinking artifact overplayed over main picture (ghosting blinking afterimage). This artifact disappears after 2 minutes on normal working and do not affect any normal behavior with this monitor.
Actually with only one connected monitor with native resolution i'm unable to reproduce this issue.
What could it be?
I understood the reason of the problem with the residual flickering image that I mentioned. It happens only if you setup resolution with less than 75hz.
The stop watch timer is not accurate, image retention is normal when displaying content which flashes rapidly for a few minutes and the monitor is supposed to be set to 75hz with Nvidia.

This or the 2795 QHD? I had a Qnix 2710 but got broken.
There are a lot of korean monitors out there that have decent bezels, compared to the ugly ones that 2710 and 2795 QHD have. But I care more about image quality.
2795=96hz overclock with no color controls versus 27S with 60hz Free-Sync or 75hz overclock, color controls and the ability to connect to other devices.

The Cobol is now finally up on ebay, "real 75Hz", and 120Hz overclock. Both the Cobol and Freedom or 27a/27s probably use AOU M270DAN01.0 or 1.2 60Hz panels so I guess we could at least assume 75-96Hz stable, 120Hz possible if lucky.
TennoJim can you help clarify about the OSD options, or take pictures for us? Translating playwares can be lacking, and the options are unclear. It sounds like stuff like brightness and rgb cannot be changed in standard mode? Only in one of the "ECO" modes?
Also did you get a remote with yours? And if so what functions does it control?
The Freedom is better since AHVA panels have more neutral and accurate color presets than Korean IPS which are almost always too green, and because the Freedom has color controls.

Okay so I ordered a 2795 from Dream seller is it possible to cancel it before shipment to order the Crossover 27S instead? Is dream seller that cooperative?
Also wanted to ask about the 27ACOBOL which is overclockable to 120hz, should I get this one over the 27S?

I would personally yes. The 2795 as NCX has said is still good, and a bit cheaper. Both probably have the same chance to overclock. I doubt that the Cobol has any more chance to reach 120Hz than the 2795 does, perhaps.
But it has a nice stand, nice osd, remote ect.
Thanks man! Looks great, nice pics too! Appreciate it. So can you control the R G B and Brightness/Contrast ect with the remote?

The thing is I already ordered the 2795 but it's not shipped yet, you think I can get dream seller to cancel it and get the 27A instead? Also the 27A is not pixel perfect, should I be worried about that?
No, they use different display boards with different inputs and the 27A has not been tested. If you think it's a good idea to buy a monitor from a company which has released many monitors advertised as being able to overclock but skip frames to save 17$, go for it. Or, you buy a monitor (27S & 2795 QHD) proven to work as advertised.

I just got my refund for the 2795, I guess I should wait then? So far what I'm seeing is 27S is the one to go for compared to 2795QHD, and the extra 15hz is a nice, imo definitely noticeable bonus.
Does overclocking the 2795 QHD to 96hz affect the backlight and colors like the 2710 so it needs calibration? And is the 27S not at all overclockable?
? is there proof somewhere of frame skipping on the 27a?
Bah, doesn't matter anyway, it's not like i wouldn't find out for sure with actual proof before i purchased one or else i wouldn't buy it. Standard procedure. Been buying and selling high dollar 2-5k dollar vintage instruments and electronic gear across the globe on ebay for over 10 years. I'm not an idiot. Should go without saying that you should get all info before you purchase anything.
But enough speculation. I'll find out for sure, or forget about it. I'm not set on it myself anyway, still looking at options. However if it does 75-96Hz, that's fine. Like i already said that's all i think we could figure it does reliably anyway, so that's all i expected in the first place.
Wait for what? I can't figure out why an informed person would buy the 27A over the 27S given the tiny price difference and fact we know the 27S is good.

It does affect the gamma according to my measurements, but only a tiny amount and not in a perceivable way. The same applies to the extinct overclock-able glossy 1440p IPS.

I'm awaiting reply on it. I emailed crossover directly. The ebay page says it uses a bypass board. Anyway, to assume that it does or doesn't without really knowing and then arguing about being "informed" while no one really is, is silly. I'll generally take NCX words into great consideration on these Korean panels, even though his attitude is kinda pissy sometimes..
So with the mod linked in theory is it possible to overclock to 75hz on a amd card and then bump up the max free sync range to go up to that? If so then I think for me it'd edge out the 2795 assuming same price.
