        BTW, @ vonvorter, since you have tested the G2724D – did you notice any interlace pattern artifacts at lower refresh rates (60 Hz – 100 Hz)?

        “On some monitors, particularly but not exclusively those with high refresh rates, interlace patterns can be seen during certain transitions. We refer to these as ‘interlace pattern artifacts’ but some users refer to them as ‘inversion artifacts’ and others as ‘scan lines’. They may appear as an interference pattern, mesh or interlaced lines which break up a given shade into a darker and lighter version of what is intended.”

        Thank you.

          No, I haven’t at all.

            Thought I would add a useful update in here:

            As stated, I’m coming from a U2417H. I received the G2724D, and unfortunately found the uniformity noticeably poor in comparison (dark sides, corners). My thinking is 27″ exaggerates this? Do Ultrasharps use more uniform panels? Also, the srgb preset on my Ultrasharp is noticeably better looking than the one on the G2724D. To be honest, I think 27″ is too large for me, yet I still want something like an Ultrasharp with fast response time (4 ms will do!) and 120 hz to match content better.

              As I always says, uniformity varies between individual units – and you may have got a poor sample of the G2724D. But some models are more prone to uniformity issues than others based on the panel used and monitor construction etc. In my experience larger models can be more likely to suffer in this regard as well – and Ultrasharps are by no means immune to such things and I wouldn’t say they’re particularly “special” in that respect. In fact I used to spend a lot of time recommending the U2719D to people and uniformity complaints were rife with that model.

              You may also be observing some ‘vignetting’ due to some viewing angle weaknesses, which won’t vary between units. Try observing the monitor from further back but keeping your head central to see if you can still observe the darker areas. If you can still see a problem it’s a uniformity issue, if not it’s viewing angle related. It could be a bit of both.

                Ah okay, I was just hoping the G2724D might overlap in the ways I was looking for.

                  @ Jarrett84, so you are returning that monitor?

                    Our review of the ViewSonic OMNI VX2728J-2K is now available. It’s a good budget option in my view – vibrant colour output, reasonable contrast performance, decent build quality, competent repsonsiveness with ‘single overdrive mode experience’. So a good all-rounder really. 🙂

                      The Dell G2724D seems to be on offer at the minute in the UK for a really cheap price. It is kind of tempting, but, I’d rather hold out for some proper in-depth reviews.

                      I believe the rtings review of the AW2724DM should be out soon too?

                        The RTINGS review of one of the AW2724DM “variants”. Should be able to see which one based on the screen surface. 😉 They’ll also be testing the G2724D.

                          Their review of the G2724D is now live. Impressive contrast for the panel type (~1400:1) and good all-round performance with well-calibrated sRGB setting and a native gamut which will please those wanting a bit of extra vibrancy beyond sRGB, but nothing too strong. Not a true single overdrive mode experience based on their testing, but it’s subjective because the ‘Fast’ setting appears to provide a decent experience throughout the range.

                            Cheers for the update. So, arguably, the G2724D is as good (Better in some cases) than the AW2724DM

                              OK, I sold the AOC 25G3ZM yesterday and I had to hook up my old trusty NEC E241N – which has terrible motion handling and tearing (60 Hz) but the colours, basically no obvious backlight bleed and just a slight IPS as well as pretty decent contrast ratio made me think of an IPS panel… And now:
                              I am seriously considering M27Q rev. 2.0 (quite a decent one, reasonable price and the KVM switch are the sellng points BUT I have found on a serious sale the IPS based Samsung Odyssey G5 (LS27AG520PPXEN) – I can have it for 295 USD (down from 390 USD) – 24% off. No info on this one in the forums. Is it worth something?

                                That’s a very specific regional designation for the Samsung – and the “L” at the start just means “LCD”. The preferred shorthand for the series is simply S27AG5x (includes S27AG50, S27AG52). So try searching ‘S27AG50’ instead and you may get some more details. I can confirm that Samsung does use a few different panels within the series and some of the S27AG52s seem to have switched to using a newer panel (originally Nano IPS with relatively weak contrast but excellent DCI-P3 coverage was used). The specific one you’re looking at uses the BOE MV270QHM-NF2. That’s a slightly older variant of the panel used in the VX2728J-2K, I’d expect some similar performance characteristics. I don’t know how much you usually pay but even on sale that strikes me as expensive for that model.

                                  You’re a walking monitor encyclopedia! Respect 🙂 Thank you very much.

                                  OK, clear then. Never been fond of anything Samsung anyway. Don’t own any of their products.

                                  Well, after reading this at RTINGS (about the M27Q ver. 2.0):
                                  “Ordered this monitor 3 weeks ago and specially V2 version. Very disappointed! Month ago bought AOC AG275QXN and wanted to compare VA panel with “good” IPS panel but this m27q v2 is not good ips panel at all! Maybe my unit was really bad but omg ips glow at right corners was so bad that watching movie I could notice it easily, then I found at least 1 dead pixel and what is strangest that ufo test on this m27q was worse then AG275QXN with VA panel, yes I tried all overdrive settings and still AOC VA panel was much better. Blacks on AOC is very deep, only good thing m27q has is little sharper colors. I was really surprised how good AOC AG275QXN is and cant understand why RTINGS don’t have review about this monitor or AG275QZN… Today I’m sending back M27Q, happy that seller accepted return.”

                                  I ordered the AG275QXN. Will get it tomorrow, we’ll see how it turns out.

                                    are you sure, the Samsung ones uses the BOE MV270QHM-NF2? Didn´t this one has a 8-Zone (or 10?) Backlight which would imply a BOE Panel with Custom Backlight? –> its one of the modells were i didn´t find much information, so i was assume it would be the ME270QHB-NF0….

                                    @ radosuaf –> because the M27Q Rev. 2.0 should use the “old” Innolux K7B-Panel, which isn´t as fast, as newer FAST IPS ones…especially if its not that good tuned….also its relatively cheap. But i can´t believe it would perform worse than one of these budget-VAs like in AG275QXN. Especially in terms of Dark Level Smearing.

                                    Sadly many of these “tech” YouTubers still do recommend the M27Q, because they never even heard of the M27Q Rev. 2.0….. 🙁 It´s a shame.

                                      Yes, see for yourself. It’s the panel listed for that model with official part number BN07-01724B. Some other S27AG52 models use the LG Display LM270WQA-SSA2, so it’s pretty confusing.

                                        @ MarzoK: I don’t expect a 165 Hz VA panel to handle motion better than an average IPS – but I do expect it to have significantly better blacks, contrast ratio and lower glow 🙂 .

                                          MarzoK said that in response to the user from RTINGS you quoted claiming this about the M27Q Rev 2.0: “what is strangest that ufo test on this m27q was worse then AG275QXN with VA panel, yes I tried all overdrive settings and still AOC VA panel was much better.” Which I agree, makes very little sense. If I’m not mistaken Tim from Monitors Unboxed should be reviewing the M27Q Rev 2.0 shortly. I’d also add that the M27Q Rev 1.0 falls short of many modern fast IPS models, but it’s significantly above the vast majority of VA panels in terms of pixel responsiveness. And it’s at a level most are comfortable with – this is based on a huge volume of feedback I’ve received directly and people have posted elsewhere. It’s why I like to use it as a reference in reviews when discussing pixel responsiveness.

                                            I’m not referring to the quote at all – motion handling is very subjective and some people are sensitive to it, some now. So that opinion does not really matter to me. I’ll see how it looks when I unpack the monitor. I have 14 days for return if it’s bad.
                                            For me the worst thing about LCD is backlight bleed. With the current state of quality control it’s more often that not that mainstream/budget IPS panels exhibit at least some of it. I’m pretty sure I would love Eizo ColorEdge ones, but they’re 60 Hz and out of my budget :).
