It uses a matte 2560x1440 LG LM270WQ1-SLC1 AH-IPS panel (proof).

The Crossover 2795QHD uses a 27" 2560x1440 resolution 8 Bit matte LG AH-IPS panel and can be overclocked.  The Crossover 2795 does not use LED PWM Dimming unlike the Qnix/X-Star monitors, has excellent colour presets, high contrast and fast pixel response times.  Its main downside is the use of a glossy black bezel which ruins the perceived black depth (Microsoft Paint Example & Monitor Example). Unfortunately, most Korean monitors use glossy black bezels, as do expensive monitors like the Acer XB270HU

Most versions (there are at least 3 for both the glossy and matte PLS versions) of the Qnix/X-Star use LED PWM Dimming which ruins motion clarity (example) and cause some people to suffer from health issues like headaches and eyestrain.  PWM Side Effects.  Blur Busters 60hz vs. 120hz.  The 2795 QHD has more accurate colours than all glossy Qnix/X-Stars (especially the new 07 glossy panel which uses PWM) and faster pixel response times/less ghosting than all PLS Qnix/X-Stars.

The 27S IPS DP Freedom can be considered delay free, uses an AH-VA panel (AUO's version of IPS), has excellent color presets and supports AMD Free-Sync (40-60hz).

Crossover 27100Q Review by Playwares
Crossover 27100Q Product Page

The 27V, 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), 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 (27V), 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.

The Crossover 27 Fast 144 uses a 27" 2560x1440 resolution 8 Bit AUO AHVA panel, a nearly grain free matte coating, has excellent colour presets, a matte black and silver bezel, fast pixel response times and a 144hz refresh rate. Free-Sync (AMD GPU required) works from 30-90fps, eliminates tearing and lag.


Discontinued glossy 2012 IPS.

The Crossover 2720MDP uses a glossy, 8 bit+FRC LG S-IPS panel.  The pixel response times are slightly faster than the Asus PB278Q, Crossover AMG and 27QW series, Dell U2713HM, Samsung S27A850D, and Qnix QX2710/X-Star DP2710, and it is free from overshoot ghosting. 

I've tested two 2720MDP's and the second one (purchased March 2014) I tested only has 1 HDMI input and much better colors than the original from 2012 (it has 2 HDMI inputs) since it has higher average gamma so the colors do not look slightly washed out and are on par with the best semi-glossy options.  The 2720MDP is the glossy, multi-input monitor to buy.

Discontinued glossy 2013 IPS.

The Crossover 2730MD is essentially the same as the 2720MDP except it has less inputs.  Both options have at least a 1 frame delay.

Discontinued 2013-2014 IPS panels with Plasma Deposition Coating

These Crossover monitors use Plasma Deposition Coating or PDC ; read about PDC here.

Read the Brightness Control section (most other multi-input Korean monitors do not have proper brightness controls, including the 27QW HDMI).

The new Crossover 27QW Sakwa (Product Page; 2015 model) has proper brightness controls and is also PWM/Flicker Free, and should be purchased over the 27QW (2014 model) and 2735AMG since Crossover usually improves their monitors each year.  Best Price.

Playerwares measured the 2755AMG's pixel response times with an oscilloscope, as well as the Crossover 2720MDP's and the 2755AMG is a bit slower than the 2720MDP but is free from overshoot ghosting.

The single input models (2735AMG, 27QW and 27QW Sakwa) can be considered delay free while the multi-input models (2755AMG, 2763AMG, and 27QWDP)  have slightly more than a frame (16.7ms) of input lag (+/- 20ms).  The QW series monitors (2014 & 2015) have better build quality than the AMG series monitors (2013)

The Crossover 27QW DP reviewe by =DEAD= has better build quality and slightly better contrast than the multi-input AMG series monitors.  The Crossover 27QW HDMI does not have proper brightness controls, but it can be considered delay free and has identical image quality.
