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.

Acer Nitro XV273K

Added the Review by IT Hardware PL and Review by PRAD 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 HAVA 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.  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.


Nixeus NX-EDG27Sv2 & NX-EDG27v2

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.

Matte 2560x1440 144hz AUO AHVA panel with AMD Free-Sync (30-144hz over Displayport and HDMI), 2x Displayport, 2x HDMI2.0.  The non-S version, the NX-EDG27v2 does not come with a height adjustable stand.  The Nixues is very accurate, but is a bit too warm (5800k color temperature) or has a minor preset orange or red dominance.  It can be considered to be display free or to have negligible input lag (TFT Central measured <5ms with the SMT Tool), but has significantly slower pixel response times than some AHVA panel using competitors, however, it is important to remember that the Nixeus is one of the cheapest 144hz 1440p non-TN panels, and that the Innolux IPS panels are also slower than the best AHVA panels such as the Acer XF270HUA bmiidprzx.


Viewsonic VG2755-2K

Added the Review by PRAD to my Best Reviewed Flicker Free 27" 1440p AHVA/IPS/PLS buying guides.

Fully adjustable, matte 2560x1440 LG AH-IPS with Displayport, HDMI, USB-C and 3x USB 3.1.  It's fairly accurate but can't fully cover the SDR (HDTV/REC 709) color spaces (limited to 89%) which prevents it from being competitive.


Viewsonic XG240R

Added the Review by=DEAD= to my Best Reviewed Flicker Free 144hz 1080p Monitors buying guide.

Fully adjust-able matte 144hz 1920x1080 AUO TN panel with AMD Free-Sync (48-144hz), Displayport, 2x HDMI (48-120hz Free-Sync), 2x USB 3.0, and 3.5mm Audio Out. 

The XG240R has accurate 60hz color presets, but the XG240R PC Monitors tested suffered from a significant gamma drop (60hz 2.3 to 1.9 at 144hz), and loss of color and shade accuracy and vibrancy when set to 144hz.  Setting the Gamma to 2.6, and setting the Gaming Settings to Custom 1 and 2 (best) improve the 144hz gamma.  The XG240R can't fully cover the SDR (HDTV/REC 709 & sRGB) color spaces, and has slightly worse overdrive than the cheaper VX2458-mhd.  The VX2458-mhd's Ultra Fast Response Time setting offers superior overdrive to the XG240R PRAD tested: VX2458-mhd versus XG240R's best overdrive setting which is the Faster setting.

Yamakasi

Yamakasi Catleap Q270

The Yamakasi Catleap uses the same glossy, 8 Bit LG S-IPS panel as the MOTV M2700 I reviewed and offers nearly identical performance. I have tested both, and the MOTV had slightly better color presets and contrast, but this is a result of inter-panel variance. The MOTV M2700 is cheaper and is easier to VESA mount since the Yamakasi needs to be taken apart to remove the gray plastic piece on the black which blocks the VESA holes.

The single input 1440p Korean S-IPS panels all suffer from an obvious preset green tint, green over-saturation after calibration, lack menus with color controls and only work with PC's when connected with a Dual-Link DVI cable.

Doesn't the G2590PX suffer from ghosting\blurry when used with an nvidia GPU?

Where did you read that?  Read the Responsiveness section of PC Monitors review.  Unlocking the color controls (set Game Mode To Off) slows the pixel response times down slightly, however this is not important unless one is going to calibrate (requires a colorimeter) or play with the settings since the monitor is very accurate out of the box.

eyeing over the Iiyama G-Master GB2560HSU-B1 , haven't seen you mention that monitor anywhere

I'm not aware of any proper reviews for that model, both iiyama and 24.5" TN quality are inconsistent, and all TN panels look awful compared to the U2715H, regardless of how much they cost.  AHVA, IPS and PLS versus TN panel comparisons here.  Save up an extra 50$ for the Asus VG279Q (144hz AHVA panel) or look for the untested, but likely extremely similar Acer Nitro VG271 Pbmiipx which sometimes sells for less.  If these are not an option then consult the Best 24-27" 144hz 1080p Monitors with Free-Sync section of my buying guide which ranks the top tested 144hz 1080p monitors.

Which of the 24" 144hz TN monitors do you think has the best color/contrast in the <250 price segment?

I don't live in Europe or rank monitors based on pricing (it varies by +/- 50$ too often) unless the company has a history of significantly overcharging for non-professional monitors like Eizo does. 

I was about to buy the LG 24GM79G-B for 212.

I removed it from the top 10 after seeing these measurements from Belgium Hardware and factoring in the dark scene banding and gamma variance between the tested units.  Belgium Hardware AOC G2590PX measurements.

choose the Viewsonic VX2458-mhd or the XG240R?

Assuming consistency (there's only one review) the VX2458 is significantly better, however, as stated in my buying guide I don't know if it suffers from dark scene banding.  The AOC G2590PX is the safest TN choice since it does not suffer from dark content banding and consistently comes with decent preset gamma. 

Or just get a VA?

If you want a VA panel consult the Best 24-27" 144hz 1080p Monitors with Free-Sync section of my buying guide.  They're fast enough if upgrading from a 60hz monitor and reviewers such as PC Monitors contain detailed analysis of their overdrive versus TN, and reviewers such as Belgium Hardware and PRAD provide pixel response time measurements which can be compared.  The PC Monitors AOC C24G1 review contains comparisons to 144hz TN panels and the Samsung FG series VA monitors.

Banding

Dawn Engine Banding by Dr NCX, on Flickr

AUO TN panels tend to suffer from very obvious and frankly horrific banding when viewing the above Dawn Engine image, as well as when viewing this 60fps Westworld trailer.  These three monitors all suffer from the same obvious banding when displaying the above image

The BenQ Zowie RL2460, Dell S2719DGF and ViewSonic VX2458-mhd (all tested by me) are free from very obvious banding when viewing both the Dawn Engine image and Westworld trailer both before and after calibration, but I did see minor banding and compression artifacts not present on my AHVA, IPS and PLS panels when viewing some dark content on the TN panels listed above.  The banding is caused by both the source and the monitors.  If I zoom in very closely to the Dawn Engine image on my ViewSonic VP2780-4K (8 bit +FRC 4K IPS with 14 3D LUT) a tiny bit of banding is preset.  Here are the BenQ Zowie RL2460 and ViewSonic VX2458-mhd

When the lights are off a bit of banding is visible, especially on the F2380MX which performs the worst despite using a true 8 bit panel, though the banding is only very obvious when viewing the monitor off angle.

Are 27" 1440p TN panels Better? No

I reviewed the Dell S2719DGF (144hz 2560x1440 8 bit AUO TN from 2018) which has better image quality than the S2716DG (144hz 2560x1440 8 bit AUO TN from 2015) , but has worse image quality than the BenQ Zowie RL2460 since it can properly cover SDR (HTDV/REC 709 & sRGB) color spaces while both Dell monitors over and under-saturate colors, as well as can come with low preset gamma (the S2719DGF I tested came with sub 2.0 preset gamma):

BenQ Zowie RL2460 vs Dell S2719DGF Calibrated Color Gamut Comparisons::

BenQ Zowie RL2460 vs Dell S2719DGF Color Gamut Comparison by Dr NCX, on Flickr

The BenQ Zowie (6 bit +FRC AUO TN panel) can fully cover both SDR color spaces (HDTV/REC709 & sRGB) without any under-saturation and only a bit of under-saturation while the Dell S2719DGF significantly over and under-saturates some colors compared to both the HDTV/REC 709 and sRGB color space, and does so significantly more when un-calibrated.  When un-calibrated it significantly over and under-saturates some colors compared to both the HDTV/REC 709 and sRGB color space.  The top left side of the triangle (HDTV/REC 709 color gamut) falls short resulting in the under-saturation of blue and medium to dark greens. Medium to light greens, yellows, oranges and some reds are all over-saturated, a phenomenon typical of AUO panels, including both their 27" 2560x1440 and 32" 3840x2160 AHVA (more balanced or pure) panels which also over-saturate the same colors resulting in green and yellow tints to browns, greys and whites, even after calibration.

Keep in mind that the S2719DGF is calibrated and has its gamma fixed in the below comparison versus being too low out-of-the-box and significantly more washed out.  Click here to see comparisons of the Dell pre-calibration or un-calibrated versus calibrated to see what a unit with low-preset gamma looks like.

AHVA - IPS - PLS VS TN

All TN panels have very restrictive viewing angles and suffer from vertical gamma shift, therefore all TN panels have bad image quality. AHVA/IPS/PLS panel glow is not a problem if viewed correctly, and not in the dark with the brightness cranked:



Since 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, though all LCD panel types look the worst when viewed from above, or looked down at.

It does not matter if one sits directly in front of their TN panel (correct way to view a TN), or how much one pays, especially since the majority (excluding Dell S2716DG & S2719DGF) of the most expensive 27" 1440p TN panels use grainier/sparklier matte coatings than AHVA/IPS/PLS panels. Calibration can vastly improve inaccurate TN panels, but a TN is a TN, and all TN suffer from obvious vertical gamma shift.

Gamma Shift

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, though all LCD panel types look the worst when viewed from above, or looked down at.

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.

So i want to know what you think i should get the XF270HUA or try XV272UP?

Acer XF270HUA bmiidprzx since there are no reviews of the XV272UP, and because it uses an Innolux IPS panel which tend to have signal loss or flickering issues.
