I just want to know if it has issues with ghosting?

It doesn't, and the XG2401 is slightly slower than the AOC newer 144hz Viewsonic TN panels.  The VX245 has less overshoot and some faster transitions which makes it better overdrive wise.

Such minute pixel response time differences are irrelevant to 99.99% of users, but the VX245 is cheaper and more accurate and consistent preset color accuracy wise.  I know since I received one today and measured the color presets as well as checked for dark scene banding and ghosting with the Ultra Fast Response Time setting.  It does not suffer from horrific dark scene banding like the Dell S2417DG, S2716DG and XG2402 (expect the same from the XG2401), but there is a little bit which is normal for a TN.


The stand is very wobbly and it of course looks awful compared to AHVA/IPS/PLS, though it does not suffer from contrast, gamma and uniformity loss at 144hz unlike most 144hz TN panels including the XG monitors.  If you can afford the VG279Q get it, especially if upgrading from a 60hz monitor.  The VG279Q is fast enough, and faster pixel response times requires vastly sacrificing image quality.

I am upgrading from my XL2411T which got color lines after 5 years.

Hm, to be honest, now that you reassured me, I find myself struggling to justify double the price just for colors.
I now have a choice between
VX2458 for 170€ new, xg2401 for ~140€ 3 months used, xg2402 190€ like new

edit: just ordered the vx2458, lets see :)

The vx2458-mhd arrived. Good colors out of the box, coming from my placeholder IPS.
However, unlike the prad.de review and you suggest, it cannot be run in Ultra Fast response time, as this will add very obvious white trailing, just like with the XG2402 on Fastest:


That leaves Advanced, which is still decent.





EDIT:

So after a couple days use, 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?

I'm looking for a 27" monitor that is thin bezeled with the hopes of eventually buying a second. I plan to use it for general use, casual gaming, I will get back into development/programming, and watching movies. I'm thinking a 2560x1440 is ideal, and have narrowed the selection down to the following, in no particular order:

U2719D/U2719DC
S27H850QFN
VP2768

I've seen that NCX has recommended the S27H850QFU in this thread http://bestmonitorsbyncx.createaforum.com/general-discussion/best-27'-2560x1440-ahvaipspls/?message=278.

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.

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.

Greatly appreciate you taking the time to answer!!!!!! :)

I'm looking to have both monitors mounted to monitor arms at some point, so VESA is important. My apologies for not mentioning that earlier. Sadly, this means I would forego the Asus VZ27AQ. Regarding the Nixeus NX-EDG27Sv2, I am looking for a relatively thin bezel monitor to make dual use ideal, but I appreciate you offering it as a suggestion.

I'm sincerely considering pulling the trigger on the S27H850QFN instead of the U2717D(C). If/when it does arrive, 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.

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 trailfree.
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.

Qnix QX2710
A korean AHVA with low hz? Do you like it?

Anyway, 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 grainyness 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.

As for the AOC G2590PX, besides overall decent test results, Adam from Pcmonitors said he generally does not recommend it due to the clearly noticeable interlace patterns.
I guess there is always a tradeoff.

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.

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, the VX does not have any grainyness, in fact it looks pretty damn sharp, thanks I suppose in part to the tighter pixel density. On the 240 the grid is definitely noticeable.
I would say my XG240R is definitely brighter than the VX I had, maybe in part due to the higher gamma I set.

Dark scene banding: On the VX it was barely noticeable (but I think I had black stabilizer on 40%).
Running the XG240R at 100 brightness and 2.4 gamma as well as black stabilizer on 8 and there is barely noticeable banding: very gradual and not very noticeable imo, nothing like the 2402 you pictured.


 Disabling black stabilizer removes most of it and lowering gamma to 2.8 as you recommended for color accuracy removes the banding entirely.
It may be worth noting that despite my relatively high brightness settings, I can still see the fully distinguished palette on http://www.lagom.nl/lcd-test/contrast.php.

hi NCX,

first of all, let me thank you for all your work and effort to the monitor review community, I had followed you advice a lot back then when I was active on [H] forums. I was glad to find out about your site!

I have an advice request that might not really fit the bill of what you usually look for / review in monitors, but I guess it doesn't hurt to try.

I am looking for a display (computer monitor or small tv) that supports 1080p signals over hdmi at 24 Hz (and also 23.976), 25 Hz and 30 Hz (and also 29.97). Reason: it will be used as proofing monitor for a signal sent to a projector when screening movies. Same signal as the one sent to the projector will be sent to the monitor using an hdmi splitter. The projector supports all those signals, so the monitor needs to handle them as well. (in addition to regular 50 Hz and 60 Hz).

I found it hard to easily search for a monitor that supports those refresh rates, I guess several do, but it's not really advertised in specs, reviews or in monitor databases. The display should be as cheap as possible. Image quality, glow, etc. are not really concerns. My current only "cheap" options are to find used Eizos (CS240, CS230, CX241, CX240, CG246) which support those signals according to the manuals, mainly because I couldn't find any other monitor where I am sure it supports all those refresh rates.

A TV could be an option as long as it's cheap, wall mountable and small (under 24"). Size and wall mountability also apply to the monitor requirements.

Any other ideas? Thanks!

Only PRAD sometimes checks for judder free playback, and 24 and 50hz support do not guarantee judder free playback.  I went through all of the 24-27" 1080p IPS/PLS PRAD reviews in my buying guide to check, and none support 24hz.  The Dell U2417H supports judder free playback of 24hz content at 60hz:

https://www.prad.de/testberichte/test-monitor-dell-u2417h/6/

Then U2515H supports 1080p 24hz, but only supports judder free 60hz:

https://www.prad.de/testberichte/test-monitor-dell-u2515h/6/#DVD

MPC-HC with MAD VR for non-blu-ray & DVD and Cyberlink Power DVD work with ReClock and may help.  There are more 27" 1440p monitors which support 24hz @1080p.  Ctrl + F in my 27" 1440p AHVA/IPS/PLS buying guide, type in PRAD and check the DVD and Video section of their reviews and External Playback Rating; I went through the first page already and did not find anything.  If the Suitable for DVD/Video (external input) rating is 3/5 or less 24hz 1080p is not supported.
