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 most 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 and/or Back-light strobing

#1 Acer XF252Q (48-240hz AMD Free-Sync & back-light strobing) TN
#2 Gigabyte Aorus KD25F (40-240hz AMD Free-Sync & Aim Stabilizer/back-light strobing) TN
#2 LG 27GK750F (48-240hz AMD Free-Sync & back-light strobing) TN
#3 BenQ XL2546 (DyAc=back-light strobing) TN
#4 HP OMEN X 25f (20-240hz AMD Free-Sync) TN
#5 Viewsonic XG2530 (30-240hz AMD Free-Sync) TN
#6 AOC AGON AG251FZ (48-240hz AMD Free-Sync) TN

There's only one review of the Acer which offers top tier pixel response times superior to some of the other tested models reviewed by the same reviewers while multiple Gigabyte (the KD25F tested by tested by Tom's Hardware tested came with low/2.00 preset gamma) and LG's were tested and proven to suffer from significant preset color accuracy variance.  It's possible that the Acer does as well, but I can't prove that it does at this point, and it one of the fastest which is why it is the highest rated model.

At 240hz 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 can vary significantly between the same models.  There are not enough reviews to know the if the BenQ XL2456 is consistent preset color accuracy wise, 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), but does suffer from some dark transparent overshoot ghosting (AMA High), or have slower pixel response times than the higher ranked competitors when the overdrive setting is lowered (AMA Off).

Best 240hz with Nvidia G-Sync

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

#1 AOC AG251FG (30-240hz Nvidia G-Sync) TN panel
#1 Acer XN253QX (30-240hz Nvidia G-Sync) TN panel
#1 MSI NXG251R (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 Acer XN253QX, AOC AG251FG and MSI NXG251R have vastly superior preset color accuracy compared to the rest, but there's only one review for each so I don't know how consistent they are.  All three also offer nearly identical gaming performance (low input lag and fast overshoot free pixel response times), so I can not pick a winner until more reviews come out.

 The Acer XB2522Q and Asus PG258Q 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 144hz Asus MG248Q and PG248Q.  The Alienware is also inconsistent preset color accuracy (gamma) and contrast wise, is inaccurate at best (preset gamma neither follows the sRGB or HDTV/REC 709 standard and causes black crush), 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:

Acer XB272Q

Review By Les Numeriqes


Acer Nitro XF252Q

Review by TFT Central

Matte 1920x1080 240hz AUO TN panel with a fully adjustable stand, VRB (back-light strobing), AMD Free-Sync (40-240hz), Displayport, 2x HDMI 2.0 (240hz), 4x USB 3.0 and 3.5mm Audio Out.  The Acer is fairly accurate but has high (2.5 average) gamma which causes black crush (loss of detail in dark scenes), though it can be reduced by setting the gamma to 1.8, but doing so sets the gamma slightly too low resulting in slightly washed out colors.  The XF252Q has negligible or extreme low input lag and the fastest pixel response times out of all the monitors TFT Central tested (oscilloscope measurements) which means it is one of the fastest LCD panels in existence, however it does suffer from a tiny bit of overshoot, especially at 60hz.


Acer XN253QX

Review by PC Monitors


Matte 1920x1080 240hz AUO TN panel with a fully adjustable stand, ULMB (back-light strobing), Nvidia G-Sync (40-240hz), Displayport, 2x HDMI 2.0 (240hz), 4x USB 3.0 and 3.5mm Audio Out.  The Acer is preset to the Standard Mode which is very accurate since it can cover 99% of the sRGB color space, however it does slightly over and under-saturate some colors like most 240hz TN panels, and has slightly flawed gamma since it is slightly too high (2.3 average), but not enough to cause black crush or loss of details in dark scenes.  The Acer has negligible input lag at 240hz (3.26ms measured by PC Monitors with the SMT Tool), as well as top tier and overshoot free overdrive with very fast pixel response times (preset Normal overdrive setting) and nearly as little color streaking and motion blur an LCD can provide without back-light strobing, which the Acer also supports (ULMB) at 120 and 144hz.  The ULMB feature does not work properly at 100hz since it drops back down to 90hz and causes stutter.

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).

Gigabyte

Gigabyte Aorus KD25F

Review by Belgium Hardware
Review by =DEAD=
Review by Tom's Hardware (low gamma)

Matte 1920x1080 240hz AUO TN panel with a fully adjustable stand, Aim Stablizer (back-light strobing), AMD Free-Sync (40-240hz), Displayport, 2x HDMI 2.0 (240hz), 2x USB 3.0 and 3.5mm Audio Out.  The KD25F's Belgium Hardware and =DEAD= tested are very accurate (preset Standard mode), can cover >93.5 of the sRGB color space (but fails to fully cover it as well as both over and under-saturates some colors), has good contrast for a 240hz TN panel (850:1-930:1), and has very fast pixel response times with no (Balance overdrive setting) or minimal overshoot and slightly faster pixel response times (Speed overdrive setting), but has high input lag at 60hz (240hz not measured; 19.8ms top screen Leo Bodnar device measurement).  The KD25F Tom's Hardware tested came with low preset gamma which averages around 2.0 resulting in washed out colors and shades, or image quality.  Tom's Hardware improved the gamma by changing the Gamma Preset from 3 to 4.
