Best Reviewed Flicker Free
240hz TN Panels

Always purchase from retailers with hassle free return and exchange policies.  Read retailers return and exchange policies before buying.[/center]

My recommendations are based off of testing more than 60 monitors and reading in-depth reviews from over fifteen reviewers across the realm.

Best Monitor Review Sites: Monitor Review Resource Center

Many monitors not found in this thread likely perform well, but it makes more sense to buy well reviewed monitors, and I like having sources to refer to, even though I do not always agree with them.

If a monitor is not mentioned it is because it has not been reviewed properly, been reviewed at all or is mediocre.  All monitors suffer from regular quality control issues: back-light bleeding and pixel issues (dead and stuck pixels).

Recommendations are PWM or Flicker Free:

I do not recommend monitors which use low LED PWM Dimming frequencies since they ruin motion clarity and cause some people to suffer from health issues like head aches and eyestrain.  LED PWM Dimming Side Effects.

Abnormalities & Quality Control Warnings

Warning: The 27" 1440p TN panels use very grainy matte coatings which reduces sharpness and clarity, and make content with white and light colours look obviously sparkly/grainy. They, along with the 24" models suffer from pixel inversion artifacts and suffer from poor quality control (especially the PG278Q).

Warning: The 27" 1440p AHVA panels used by the 1440p AHVA G-Sync monitors tend to suffer from poor quality control including back-light bleed and brown or yellow stains, and may come with dust or dirt stuck under the matte coating which is non-remove-able.

Warning: 144-240hz TN panels tend to suffer from pixel inversion artifacts which are shimmering mesh patterns which appears during motion on certain colors.

Warning: The color accuracy and contrast of the 240hz TN panels can vary significantly between the same monitors, and they are limited to 89-93% sRGB color space coverage which prevents them from being as accurate and vibrant as the best 144hz TN panels.

Best 240hz with AMD Free-Sync

#1 LG 27GK750F (48-240hz AMD Free-Sync & back-light strobing) TN
#2 Viewsonic XG2530 (48-240hz AMD Free-Sync) TN
#3 BenQ XL2456 (30-240hz AMD Free-Sync) TN
#4 AOC AGON AG251Z (48-240hz AMD Free-Sync) TN
#5 BenQ XL2450 (30-240hz AMD Free-Sync) TN
#10 BenQ XL2740 (30-240hz AMD Free-Sync) TN

So far the LG is the best as well as most consistent based on the two reviews available, plus it is the only monitor which comes with both AMD Free-Sync and 144hz back-light strobing.  All of these monitors offer low input lag and very fast pixel response times or extremely similar gaming performance, but their contrast and preset color accuracy or image quality varies significantly between the same units, and all are easily bested by the LG 27GK750F currently.  There are not enough reviews to know how consistent the BenQ XL2456, and it has abysmal out-of-the-box image quality, but it can be greatly improved by switching to the Standard Picture Mode (applies to all BenQ GL/RL/XL series monitors).

Best 240hz with Nvidia G-Sync

Blur Busters G-Sync Input Lag Testing & Optimal Lag Reducing Game Settings

#1 AOC AG251G (30-240hz Nvidia G-Sync) TN panel
#2 Acer XB2522Q bmiprz (30-240hz Nvidia G-Sync) TN panel
#3 Alienware AW2518H (48-240hz Nvidia G-Sync) TN
#4 Asus PG258Q (30-240hz Nvidia G-Sync) TN panel


The AOC seems to be the best by a considerable margin preset color accuracy or image quality while the Acer and Asus are inconsistent and can come with mediocre or low preset gamma which results in washed out colors. The Asus comes with intentionally over-saturated colors which results in detail loss while the Acer does not. This also applies to the Asus MG248Q and PG248Q.  The Alienware is also inconsistent preset color accuracy (gamma) and contrast wise, is inaccurate at best, but is not intentionally over-saturated and is cheaper than the Asus.

Example of Asus PG258Q (left) over-saturation resulting in detail loss and weird colors vs normal monitor (IPS panel on the right) by SweClockers:

AOC

AOC AG251FZ

Measurements and Review by Belgium Hardware
Review By IT Hardware Poland
Review By Les Numeriqes (terrible contrast and preset gamma)
Review By Sweclockers
Review By Tomís Hardware

The AOC uses a 240hz matte 6 bit +FRC AUO TN panel with AMD Free-Sync, suffers from the typical contrast and gamma lottery (TFT Central set the gamma from Mode 1 to 3), but has accurate preset RGB levels, especially the unit tested by Belgium Hardware. The AOC has very fast pixel response times with zero overshoot ghosting when the overdrive setting is set to Medium.

The AOC has mediocre image quality due to its low preset gamma and sRGB color space coverage (89% out of the box and 91.1% after calibration).


AOC AG251G

Review By PC Monitors

Very accurate matte 240hz 6 bit +FRC AUO TN panel with Nvidia G-Sync.

Asus

Asus PG258Q

The Asus PG258Q has a fully adjustable stand, a fake frame-less casing with a perceived black depth reducing inner black bezel, Displayport (240hz, G-Sync and ULMB), HDMI (60hz) and 2x USB 3.0 ports. The PG258Q is preset to the Racing mode which suffers from inteionally over-saturated colors (reduce Saturation setting to fix) preset color accuracy (gamma) variance (low preset gamma averaging around 1.8 or 2.1-2.2), though units with low gamma can be improved by switching the gamma setting from 2.2 to 2.4 on units with low preset gamma. The PG258Q's sRGB color space coverage is also below average in the 90-93% range.

BenQ

BenQ Zowie XL2450

Matte 240hz TN panel with back-light strobing.  The BenQ XL2450 has horrible color presets and can only be improved to the point where it is passable by switching it from the horrible FPS Picture Mode to the Standard mode and by changing the Gamma to Mode 3.

BenQ Zowie XL2456

Matte 240hz TN panel with back-light strobing.  The XL2456 has the worst preset color accuracy I've seen in a review aside from the first 2560x1440 AH-IPS panel with Plasma Deposition Coating from Monoprice in 2013 thanks to the BenQ's FPS modes very low gamma (<1.6) and contrast (300:1). Fortunately the BenQ can be improved by switching from the abysmal preset FPS Mode to the Standard Mode to provide decent results for a TN panel, as is the case for all of their gaming monitors. Choose between some overshoot ghosting (preset AMA High overdrive setting) or slow pixel response times versus competitors (AMA Off), this also sadly applies to most BenQ gaming monitors.
