A korean AHVA with low hz? Do you like it?

The single input (Dual-Link DVI) Qnix/X-Star monitors from 2013-2015 used at least three different Samsung PLS panels.  I lucked out and got a glow and PWM free matte Qnix, a PWM free glossy Qnix (sold) in 2013, and a PWM free glossy X-Star in 2014.  I tested all four 144-165hz AUO AHVA panel using G-Sync monitors but stuck with the PLS panels since I prefer gloss, and of course prefer glow free matte over non-glow free matte.  They can only OC to 92-96hz and suffer from significantly more color streaking (vs 144-165hz AUO AHVA) which I do notice, but they're not slow enough to bother me even though I've used all of the fastest monitors.  Glossy and matte Qnix PLS gallery.

I wasn't satisfied with the vx2458-mhd's brightness, so it will be returned.
I found an XG240R for "only" 220 from a private seller and I decided to get that instead.
So far the only thing I dislike is the grayness in bright scenes, which the VX did not have.
The luminence consistency is an improvement however. My vx had noticeable coronas, this one looks clean.

The peak brightness of both the VX and XG is around 300-350cdm/2 and will vary along with the brightness and color uniformity.  Anyway, you reminded me that I did not notice obvious grain on the VX which is pretty rare for TN panels aside from the S2719DGF.  Please check the XG240R for dark scene banding.

Yes, I was on 144hz Standard when viewing the UFO ghosting test. It was present when I had just unpacked the monitor, but not anymore a couple days later. It now looks nearly trail free.
Tried the statue test, couldn't really make out any artifacts.
Scrolling thru text isn't very pleasant, that and the lack of gamma options would be the only major downsides for me.

My units' Ultra Fast setting causes a bit of dark transparent overshoot on the white clouds when dragging the Overwatch Illios screen shot around quickly, but I did not see any with anything else I tried, and I still consider it top tier  The Text Viewing Mode and some of the others lock the Response Time setting to the slower Standard setting, but it's not an issue since the Standard Viewing Mode is the best.  The gamma is slightly too low, but it's also too high in the Text mode, and far less accurate when the other Viewing Modes are selected.  The VX2458-mhd is definitely the best TN panel I've tested aside from the BenQ Zowie RL2460HT (no review) since it doesn't suffer form horrific dark scene banding or gamma and contrast loss at 144hz.  The VX does have a gamma setting (Black Stabilization) but it decreases or increases the gamma far too much and greatly decreases the accuracy when changed.

VX2458-mhd Ghosting/Overdrive Analysis section from my review. I don't have a pursuit-capable camera so my photos look different than other reviewers who provide pursuit photographs which accurately simulate eye-tracking induced motion blur.

Nixeus NX-VUE27S

Added the Review By Tom's Hardware to my Best Reviewed Flicker Free 144-165hz 1440p Monitors and Best Reviewed Flicker Free 27" 1440p AHVA/IPS/PLS buying guides.

The PRO Vue 27P uses coated tempered glass some call Plasma Deposition Coating, is fairly accurate once set to the User mode, but has high input lag (>20ms) for a modern (2019) 1440p monitor.  PDC coated monitors are the clearest, least reflective and most vibrant type of glossy monitors, but the black looks greyish due to the perceived black depth decreasing glass covered black bezel.  The perceived black depth can be increased with bias lighting (light placed behind the display) or by placing non-stick silver tape tape on the black bezel.

5
what information can I use to see if it is in fact the same model, just the North American variant?

They probably are the same if they have the same inputs and manual information (download from the official Samsung site and compare).  I don't know is if 75hz is natively supported or only supported when Free-Sync is activated in the AMD Catalyst Center, or if the Samsung has a separate Free-Sync mode which needs to be selected for 75hz to show up.   For example, the HP 27Q needs to have the Gaming Free-Sync Viewing Mode selected for Free-Sync to work and for 75hz to work without dropping frames.  The HP 27Q is available in North America, but the unit Rtings tested suffered from severe image retention so I don't recommend it.

VESA mounts are over-rated and a waste of money in many cases if they do not allow for AHVA/IPS/PLS to be set high enough to prevent glow.

I swapped to the Ultra Fast setting again and the obvious white trailing is gone?
Is this normal behaviour? Does a monitor need some sort of warming up?

It could be a firmware bug, also, some of the View Modes such as the Text Mode locks the Response Time setting to the default Fast setting.  Were you viewing the same content (Test UFO Ghosting Test) when you noticed the lack of or presence of overshoot? 

When panning the camera at 60hz the grey circular Traveler in Destiny 2 (30 FPS on the PS4) suffers from a tiny bit of dark transparent overshoot ghosting when the sky is blue.  In game motion blur tends to increase overshoot ghosting.  Many monitors struggle when white and light blue; try dragging this screenshot from the Overwatch map Illios and pay attention to the giant statue and white clouds.  I have not done this yet but will be tomorrow, as well as more extensively looking for overdrive problems.

7
My questions are:
1. Are those displays numbered based on the rank, with the S27H850QFU being the best option of the bunch?
2. Given that the S27H850QFU is a European model, is the S27H850QFN the American equivalent, and if so, should I just go for that over the U2719D(C)?

1.) Yes.  Very few monitors under 1000$ are as accurate as the S27H850QFU, plus it offers top tier gaming performance aside from being limited to 75hz.

2.) Don't know hence not mentioning it, and the 75hz Asus VZ27AQ is a better choice for gaming than the Dell and ViewSonic.  If you can increase your budget a bit the 144hz Nixeus NX-EDG27Sv2 (with height adjustable stand) NX-EDG27v2 (non-adjustable stand) is also great.

Conclusion

DSC_0304 by Dr NCX, on Flickr

+Competitive price
+No contrast, gamma or uniformity loss when set to 144hz vs 60hz
+AMD Free-Sync support over Displayport (48-144hz) and HDMI 2.0 (48-120hz)
+Nearly grain and sparkle free matte coating allows for increased clarity and vibrancy of light colors and white
+Minimal banding when displaying dark content
+Fairly accurate
+TN panel with exemplary image homogeneity and reduced vertical gamma shift
+Balanced overdrive with no overshoot and very fast pixel response times (default Advanced Response Time setting) at both 60 and 144hz
+Negligible input lag

-Stand wobbles very easily
-Dead white pixel in the bottom right corner
-Glossy black bezel reduces perceived black depth
-Preset RGB Level accuracy could be better
-Miss-matched color gamut with over and under-saturation
-TN panel with obvious vertical gamma shift
-TN panel with very narrow and restrictive viewing angles
-Minor horizontal gamma shift and hour-glass shaped image distribution


The ViewSonic VX2458-mhd is a great budget friendly gaming monitor, but sadly this is mainly because many of the 144-165hz AUO TN panels have severe functionality and image quality issues, and not because it offers excellent all around performance.  The VX2458-mhd is not a super accurate TN panel, but it does not suffer from obvious issues such as severe banding when displaying dark content, low gamma, contrast, gamma and uniformity loss when set to 144hz, as well as has atypically uniform image homogeneity or reduced vertical gamma shift compared to most TN panels.  It also offers outstanding gaming performance without any real flaws such as the need to change the overdrive setting when changing the refresh rate, and it's more accurate than many of the more expensive 1080p 144hz TN panels.  The ViewSonic VX2458-mhd is the best 144hz 1080p TN panel without G-Sync as of May 17th 2019, and until otherwise noted in my Best Reviewed Flicker Free 144hz 1080p Monitors buying guide.

Gigabyte AORUS AD27QD

Added the Review by TFT Central 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 wide gamut Innolux IPS panel with Displayport, 2x HDMI 2.0, HDR support+, RGB Lighting, 2x USB 3.0 and 3.5mm Audio In & Out.  The sRGB mode must be selected to prevent the 30% wide color gamut over-saturation of non-HDR sources and ensure maximum color accuracy.  The sRGB mode locks the brightness and color controls and leaves the monitor stuck at over 180cdm/2. 

The Balance overdrive setting is the best for 60hz while both Balance and Speed are useful with 144hz, however, the Speed setting adds quite a bit of overshoot ghosting which may disturb even casual gamers and display users who usually do not notice overdrive flaws.  I recommend using the Balance setting for all refresh rates, as well as can't recommend this monitor to those who are upgrading from fast LED PWM Dimming or Flicker Free 120hz+ monitors.  The Balance overdrive setting has significantly slower pixel response times than all five* of the 144-165hz 1440p AUO AHVA (marketed as IPS) panels with G-Sync, however, the Gigabyte is significantly more accurate than all of them aside from the ViewSonic XG2703-GS which was discontinued in summer of 2018.

+It can accept an HDR signal and dsiplay 95% DCI-P3 color, but is less (470cdm/2 with HDR on) than half as bright as the HDR standard brightness of 1000cdm/2, and lacks local dimming result greyish black and washed out dark content due to the 1100:1 contrast ratio.  Bright bias (light placed behind the display) or room lighting can help trick the eyes into perceiving greyish black as true black.

iiyama XUB2792UHSU-B1

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

Matte 4K IPS with very accurate color presets, negligible input lag, but slower than average pixel response times for a 60hz AHVA/IPS/PLS panel.  It has a fully adjustable stand, Displayport, Dual-Link DVI (1440p), HDMI 2.0, 2x UXB 3.0 (1x fast charging), and 3.5mm Audio In and Out.

Below are PRAD's oscilloscope measurements of three 27" 4K monitors pixel response times, including the VP2780-4K from 2015 which I own.  The iiyama's +2 overdrive setting speeds up the pixel response times significantly, but also causes overshoot ghosting.  The +1 setting provides a better balance between speed and overshoot.  The iiyama's overdrive is fine for casual gaming, but there are better options.

Non-curved and non-semi-wide gamut matte 60hz 3840x2160 Samsung VA panel with HDMI, mini-Displayport and USB 2.0.  The 32" version IBXT tested is very accurate, as well as more accurate than the 144hz 2560x1440 27" S27R750QEI =DEAD= tested which has low preset gamma which can be improved by selected Gamma Mode 2.

Xbox 360 & Xbox One

DSC_0312 by Dr NCX, on Flickr

The ViewSonic does not automatically detect and correctly display the default 16-235 signal consoles send out, but it does have an HDMI Black Level settings located in the Color Range sub menu in the Color Settings main menu.  I recommend using these console settings since changing the monitors settings affects all inputs and will negatively affect other inputs if one forgets to change the settings back when the display is connected to devices which send out different or incompatible signals.

The Xbox 360 must have its YCbCR709's setting selected to prevent the image from being washed out since the other settings send a 16-235 signal which causes the display to be washed out

Xbox One & Xbox One X

The ViewSonic looks washed out when connected to the Xbox One and Xbox One X since it does not automatically detect and correctly display the signals the Xbox and Xbox One X send out.  To rectify this Go to the Settings > All Settings > Display & Sound > Video Output > Color Space and change the setting from Standard to PC RGB.  The ViewSonic does have HDMI Black Level settings located in the Color Range sub menu in the Color Settings main menu, but I recommend using these console settings since changing the monitors settings affects all inputs when the display is connected to devices which send out different or incompatible signals.

The ViewSonic supports Free-Sync with the One S and One X if the Free-Sync setting is selected (Color Control Menu>Viewing Modes>Gaming FreeSync), and if the Allow variable refresh rate setting is selected in the Xbox One S and X's Display & sound Advanced video modes menu.  Here's how to access this setting:

Quote from: Xbox One FreeSync and Variable Refresh Rates: Everything you need to know by Matt Brown


1.) Open the Settings app on Xbox One.
2.) Navigating to the Display & sound tab.

The ViewSonic scales 1280x720 (important for PS3) without issue.  The ViewSonic does not automatically detect and correctly display the default 16-235 signal consoles send out, but it does have an HDMI Black Level settings located in the Color Range sub menu in the Color Settings main menu.  I recommend using these console settings since changing the monitors settings affects all inputs and will negatively affect other inputs if one forgets to change the settings back when the display is connected to devices which send out different or incompatible signals.

PS3:

Go to Settings>Display Settings>Scroll down and select RGB Full Range (HDMI)

Go to Settings>Video Settings>Scroll down and select 1080p 24hz Output Automatic.

To use external audio devices use the 3.5mm audio in & out ports located on the back of the Crossover or use the included Playstation 3's RCA cord:

Or insert an optical cord into the optical out port located at the back of the PS3 or 4 to connect the PS3 or 4 to an external device such as a DAC.

PS4:

Go to Settings>Scroll down and select Sound and Screen>Video Output Settings>Resolution: 1080p>

Vertical Gamma Shift & Viewing Angles

DSC_0329 by Dr NCX, on Flickr

Correct Way to View TN Panels

Correct Way To View TN LCD Panels by Dr NCX, on Flickr

TN panels suffer from vertical gamma shift: their colors and shades are uneven from top (top quarter is too dark) to bottom (bottom half is washed out), as well tend to have more banding, and always have vastly less wide, or more restrictive viewing angles than other panel types.  VA panels suffer from horizontal gamma shift which causes the sides of VA panel to be significantly lighter or washed out compared to AHVA, IPS and PLS panels. VA panel gamma becomes lower, and colors and shades become more washed out the further away from the center.  AHVA, IPS and PLS panels do not suffer from gamma shift at all, and thus are able to display colors and shades evenly across the panel. 

The BenQ Zowie RL2460 and ViewSonic VX2458-mhd both use AUO TN panels with vertical shift, but the ViewSonic suffers from less gamma shift in the bottom half of the panel, however it does appear to suffer from a bit of horizontal shift as well and have a dark wide hour glass shape spanning across most of the panel, though the grey bar panels still appear more even over all compared to the BenQ which has a significantly more washed out bottom half than the VX2458-mhd.  The ViewSonic VX2458-mhd offers atypical and exemplary homogeneity for a TN panel, however it still suffers from obvious gamma shift and looks washed out compared to good AHVA/IPS/PLS and VA panels.

Perceived Black Depth & Glow

DSC_0171 by Dr NCX, on Flickr

The VX2458-mhd's perceived black depth is poor since it has less than 1000:1 contrast (typical for TN) and has a glossy black bezel which reduces the perceived black depth since it looks much darker next to the matte panel which look distinctly different, a bit hazy and lighter when displaying black and very dark content.  If used with bright bias (light behind the display) or room lighting black looks fairly dark and black, but not compared to monitors with similar contrast ratios and matte grey bezels like the Acer XF240H and ViewSonic XG2401. 


TN View by Dr NCX, on Flickr


TN glow has never been an issue to worry about unlike with AHVA/IPS/PLS and VA panels since TN panels look awful when not viewed in one specific way which is from above, or while being looked down at.
