Brightness & Contrast

DSC_0781 by Dr NCX, on Flickr

Acer EB321HQ awi B & C by Dr NCX, on Flickr


The Acer has a 64.7-292.7cdm/2 brightness range, and a 980:1 contrast ratio which is typical for AHVA, IPS, PLS and TN panels.  The Acer is dim (64.7cdm/2) enough for use in light-less rooms at 0% brightness (0/100 in the menu), and bright (292.7cdm/2) enough for use in open and brightly lit rooms as long as the monitor is not being hit by direct sunlight on a bright day.

Input Lag

DSC_0887 by Dr NCX, on Flickr

The Acer can be considered delay free or to have negligible input lag since it has a 2.5ms (top screen Leo Bodnar measurement) delay.  Most non-professionally oriented monitors have equally as low input lag while very few TV's have less than 10ms when tested with the Leo Bodnar device.

Ghosting/Overdrive Performance

Acer EB321HQ Overdrive Setting Comparisons

Acer EB321HQ Awi OD Normal VS Extreme by Dr NCX, on Flickr

^The above compilations are of photos of the Test UFO Ghosting Test on the monitors featured in the compilations.  The photos are slightly out of focus.  The transparent bright after image trailing the UFO in the OD Extreme photos is overshoot ghosting which appears in the form of transparent bright colored, black or white glow on color and shade transitions moving across the screen.  The OD Extreme setting is useless since it suffers from obvious overshoot ghosting.

The Acer is marginally slower than the fastest 60hz AHVA, IPS and PLS panels like the Acer XB321HK (>900$ 4K AHVA panel) and HP 25f (AH-IPS), but it is still fast enough for 60hz gaming and watching movies and TV shows.  The overdrive setting named OD is correctly preset to the Normal setting which provides a completely overshoot ghosting free gaming experience.  The slightly slower pixel response times cause some obvious color streaking, especially with yellows and whitew hen quickly panning the camera in games, especially while viewing the white clouds in the Overwatch map Illios's light blue sky. 

Multi-Monitor Test UFO Ghost Test Comparison

Acer EB321HQ vs BenQ RL2460 vs HP 25f vs Samsung 43NU7100 by Dr NCX, on Flickr

The BenQ Zowie RL2460 is one of the fastest 60hz TN panels while the HP 25f is one of the fastest IPS type panels.  The Samsung uses a VA panel with very slow pixel response times, and uses a low frequency LED PWM Dimming frequency which increases motion blur significantly.  The trailing, faint, secondary UFO after image is a bit more pronounced since the Acer has slightly slower pixel response times than the HP which is slightly slower than the BenQ.  I call the type of ghosting the Acer, BenQ and HP suffer from streaking, and call the far more pronounced and darker trailing or after image the Samsung VA panel suffers from smearing.

The overdrive flaws are minor and will not negatively impact casual 60hz gaming, or people who do not want, or can't afford equally sized 75-144hz monitors.  The Acer has faster pixel response times and less motion blur than most low-mid range TV's which use slower VA panels with low frequency LED PWM Dimming or flickering back-lights which increase motion blur.

Almost-Glossy/Low Haze Coating

DSC_0764 by Dr NCX, on Flickr

The EB321HQ Awi uses the same almost-glossy or low haze coating as the 25 & 27" HP 25 CW/er/es/f/XW, HP 32 Spectre monitors, and the Qnix UHD32R I reviewed.

The almost-glossy or low haze coating is equally as free from grain and sparkle, as equally as clear as a glossy coating, and is less reflective. The almost-glossy coating is also free from obvious white haze which semi-glossy coatings suffer from when displaying dark content in brightly lit rooms.  Reflections are not as transparent and clear as glossy coating reflections, but the reflections are slightly less pronounced.  The coating the Acer uses also does not look grainy when viewed off angle like the coating the Qnix UHD32R I tested used.

In brightly lit rooms the coating the Acer uses is less reflective and looks better than the semi-glossy coating almost all non-high end TV's use.  Compare the Acer to the Qnix UHD32R, Samsung 43NU7100 and Samsung 43X750F:

Flicker/PWM Dimming

DSC_0888 by Dr NCX, on Flickr

The Acer is advertised as Flicker Safe, which means it does not use back-light flicker or LED PWM Dimming (read about the side effects), regardless of high or low the brightness is set.  I checked for and did not see LED PWM Dimming with the Blur Busters Test UFO Blur Trail/PWM Test with 0-100% brightness settings in the Acer's menu. The lack of PWM is a good since PWM or Flicker ruins motion clarity (example), and makes some people suffer from health issues such as headaches, and/or eyestrain.

Menu & Set-Up

DSC_0873 by Dr NCX, on Flickr

There's no need to change any settings aside from the Black Level setting since the preset gamma is slightly too low.  Change the Black Level setting from 5 to 3 to increase the gamma, accuracy and vibrancy.

Correct Way To View AHVA/IPS/PLS & VA

Correct Monitor Viewing Height by Dr NCX, on Flickr

The top left image shows the correct way to view IPS type (AHVA, IPS, PLS) and VA panels, but most importantly IPS LCD panels.  Doing so vastly reduces white glow when viewing black and dark content, especially if the display brightness is not cranked in a dimly lit room.  IPS vs TN: Right & Wrong Ways To Use Or View; How To Vastly Reduce AHVA/IPS/PLS Glow & Vastly Increase The Perceived Black Depth

Features & Stand

Acer EB321HQ Awi Front 20s by Dr NCX, on Flickr

The Acer only has 1x HDMI and 1x VGA inputs, but it is VESA compliant.  The case is made of sturdy white plastic, and the stand is made of metal, and only allows for slight tilting.  I tested a returned unit without the original accessories or box; the official Acer website states that the Acer comes with a power cable and VGA cable.

Monitor Reviews by NCX / Acer EB321HQ Awi Review: Glossy* 1920x1080 IPS
« Last post by NCX on March 26, 2019, 03:35:12 am »

The EB321HQ Awi uses the same almost-glossy or low haze coating as the 25 & 27" HP 25 CW/er/es/f/XW and 4K HP 32 Spectre monitors, and the Qnix UHD32R I reviewed.  Asus (VA325H), LG (32MP68) and Philips (323E7QDAB) all sell EB321HQ Awi equivalents, but there are no reviews. 

*I'm not sure if it has an AHVA, IPS (Innolux or LG), or PLS panel, but suspect it has an AHVA panel since it suffers from vastly less glow than everything else aside from the 32" 4K AUO AHVA panels in monitors like the BenQ BL3201PH/PT, PD3200U and multiple 4K Qnix monitors (I reviewed the matte UHD3216R & almost-glossy/low haze coated UHD32R).  The 32" 4K AUO AHVA panels glow more than the Acer, but less than IPS panels ,smaller AHVA panels and PLS panels aside from the TLM270DL06 mentioned above.

Acer X27

Added the Review by TECHSPOT to my Best Reviewed Flicker Free 27" 4-5K AHVA/IPS/PLS buying guide.

Matte 4K AHVA panel with 98hz (8 Bit +FRC / 10 bit HDR 4:4:4), Nvidia G-Sync, height adjustable stand, 4x USB 3.0, local dimming and true HDR color.  Proper color (YcBcr 4:4:4) is only supported up to 98hz.  Image quality is degraded at 99-144hz.  Read my X27 versus PG27UQ comparison here.


Acer Nitro XV273K

Added the Review by Sweclockers and to my Best Reviewed Flicker Free 27" 4-5K AHVA/IPS/PLS buying guide.

The Acer XV273K has an accurate 144hz (achievable only when connected with 2x Displayport cables) 3840x2160 or 4K matte wide gamut AUO AHVA panel which can cover 97% of the DCI-P3 color space, and can fully cover the sRGB color space to prevent over-saturation when the sRGB mode is available, but doing so locks the color controls.  It has a fully adjustable stand, a monitor hood, 2x Displayport, 2x HDMI 2.0,4x USB 3.0 and a 3.5mm Audio Out


AOC AG273QCX

Added the Review by PC Monitors to my Best Reviewed Flicker Free 144hz 1440p Monitors buying guide.

Curved (1800R) matte 2560x1440 144hz semi-wide gamut fake bezel/frame-less VA panel with back-light strobing (120hz MBR), 2x Displayport, Free-Sync (48-144hz range over Displayport & HDMI) 2x HDMI 2.0, VGA, 4x USB 3.0, 3.255 Audio In and a fully adjustable stand.  The AOC has low preset gamma (1.9 average) resulting in washed out image quality which can be vastly improved by setting the gamma to 3 which increases the gamma to 2.2 which provides proper saturation of colors and shades.  The AOC has an sRGB mode to prevent the wide gamut over-saturation of non HDR (DCI-P3) content, but suffers form a present green tint and has locked color controls.  The Medium overdrive setting is best for 60hz while Strong is the best for 144hz.  The Strong overdrive setting suffers from a bit more smearing than the faster Samsung C27HG70 which has a perceived black depth increasing matte grey bezel.  The AOC is G-Sync compatible, but it flickers and the overdrive setting is locked to Off which reduces the pixel response times and causes very obvious smearing.


Asus PG27UQ

Added the Review by Sweclockers and the Review by TECHSPOT to my Best Reviewed Flicker Free 27" 4-5K AHVA/IPS/PLS buying guide.

Matte 4K AHVA panel with 98hz (8 Bit +FRC / 10 bit HDR 4:4:4), Nvidia G-Sync, height adjustable stand, 4x USB 3.0, local dimming and true HDR color.  Proper color (YcBcr 4:4:4) is only supported up to 98hz.  Image quality is degraded at 99-144hz.  Read my X27 versus PG27UQ comparison here.


Gigabyte AORUS AD27QD

Added the Review by =DEAD= to my Best Reviewed Flicker Free 144-165hz 1440p Monitors and Best Reviewed Flicker Free 27" 1440p AHVA/IPS/PLS buying guides.

Very accurate and fully adjustable matte 2560x1440 144hz semi-wide gamut Innolux IPS with Displayport, 2x HDMI 2.0. RGB Lighting, 2x USB 3.0 and 3.5mm Audio In & Out.


MSI Optix MPG27CQ

Added the Review by Playwares to my Best Reviewed Flicker Free 144hz 1440p Monitors buying guide.

Curved semi-wide gamut matte 2560x1440 144hz VA panel with AMD Free-Sync (48-144hz range) 2x USB 3.0, Displayport, 2x HDMI 2.0, 2x USB 3.0, a height adjustable stand and a fake frame-less casing with a perceived black depth reducing inner black bezel.  It's pretty accurate aside from the gamma which is a bit high in the 0-10% white range resulting in a bit of black crush.  The Pro mode is the most accurate color preset.  The MPG27CQ is worth paying more for to those who do not own accurate colorimeters since the MPG27CQ offers good preset color accuracy while the MAG27CQ is awful.


MSI Optix MAG271C

Added the Review by Playwares to my Best Reviewed Flicker Free 144hz 1080p Monitors buying guides.

Very accurate, curved, matte, 144hz  1920x1080 semi-wide gamut VA panel with Displayport (144hz), Free-Sync (48-144hz) 2x HDMI (120hz) and 2x USB 2.0 ports.  The MAG271C is pretty much the same as the AOC C27G1.


Samsung C32HG70QQ

Added the Review by Sweclockers to my Best Reviewed Flicker Free 144hz 1440p Monitors buying guide.

Curved matte 2560x1440 144hz VA panel with AMD Free-Sync, back-light strobing and a perceived black depth increasing matte grey bezel.  It uses LED PWM Dimming or Flicker when the brightness is set below 70/100 which TFT Central measured to be a very bright 250cdm/2. Back-light strobing is activated when the Response Time setting is switched from Standard to Faster, and Fastest.  The Samsung is fairly accurate, but Sweclockers unit came with high preset gamma which averages around 2.36 which causes black crush or loss of detail in dark scenes.  Changing the gamma to mode 2 brings the gamma closer to averaging around 2.2 and increases the accuracy, as well as reduces black crush.
