A thorough & informative review, as always. Before upgrading to my Asus PG35VQ 200Hz in November 2020, I was an early 1440 adapter with a Dell U2711 27" monitor,10 years earlier which was IPS & 60Hz. The new OLED monitors are a fantastic development for gamers and I wish I could have bought a much cheaper OLED Alienware Ultrawide instead of my VA panel PG35VQ which was incredibly expensive in November 2020 even after a hefty Black Friday discount. These new Asus & Corsair OLEDs are also very expensive but if you can wait until this November's Black Friday sales then worthwhile savings are bound to be available. I have an Asus Zenbook OLED 16" laptop & upgraded my TV this week to a LG G2 55" so I'm a complete OLED convert. Note your comments re office work and OLEDs but for gamers & TVs, can you beat an OLED screen nowadays?

I think a 240Hz OLED monitor is pretty much holy grail for a high refresh rate G-Sync/FreeSync monitor right now, as the OLED quick pixel response makes this the same as like 360Hz or maybe even 500Hz TN (maybe not quite 500Hz TN), but you don't get the same image fidelity in terms of colour depth/contrast/viewing angle & colour width as you do with a good OLED panel - so a gaming OLED is almost like photographers dream married with gaming dream in terms of image fidelity. If you're gonna bother spending this much on a monitor then you do have to choose carefully, and you'd either buy one that you know was factory calibrated to a very good standard or you'd buy also a colourimeter device so you could measure you screen & optimise & balance the greyscale & colours through the OSD (on screen controls of the monitor), and then you'd perhaps use the included software of the colourimeter (eg SpyderX, etc) to apply an ICC profile on top of those optimised OSD controls to eek out the last remaining accuracy of the monitor. If you're gonna be spending a lot on your monitor, don't do it by halfs! Until that point I think a quality fast IPS monitor is the next best thing for a gaming monitor whilst still having general good image fidelity.

Well there are articles explaining the Pros & Cons of IPS v VA v OLED but I think the new OLEDs are best for 'most' gamers. If you reckon a 240Hz OLED equates to a 360Hz due to the OLED's quick pixel response then I guess e-sporters would be happy with that 240Hz OLED? My Asus PG35VQ has a 200Hz refresh, HDR1000, GSynch Ultimate & a VA screen, it's therefore much better at dark images than a IPS when gaming so personally I won't go for an IPS screen when I upgrade one day. I upgraded my TV from a 6 year old Sony 4K VA to a LG G2 55" last week and although I use an OLED laptop, I'm blown away with the fantastic OLED screen. Re calibrating, yes it's best to use a colourimeter but I used the screen settings recommended by TFT Central when they reviewed my PG35VQ and I'm very happy with those recommended settings but I just know the Alienware OLED Ultrawide would blow my PG35VQ out of the water (at a much cheaper price) but it wasn't anywhere near being available in 2020.

That's a little bit too much for a non-4KUHD monitor. Can manufacturers please stop using old panels with old resolutions please? As an aside, I have no problems upscaling to 4KUHD on any games using a simple calculation for a spreadsheet which goes a little bit like this: A Column = Display Width B Column = Display Height C Column = Aspect Ratio D Column = Pixel Count E Column = nK (what the 'K' number is) Enter the width and height into (a) and (b) and the following formulas into your spreadsheet for C, D and E C = "=(A2/B2)& ":"&(B2/B2)" D = "=A2*B2" E = "=A2/1024" Then simply drag down to make as many rows as you personally need so the calculations tally accordingly. This monitor gives me this: Aspect Ratio = 1.7777777778:1 (you can round this number down in your cell settings) Pixel Count = 3,686,400 (this number is important for calculating the VRAM usage) nK = 2.5K So, if you got a game which you want to run at a lower resolution, then you can easily calculate the correct aspect ratio for the monitor you are using to make the best use of the upscaling. In short, I use a 1080P/1440P/900P resolution in-game, and I know that it will upscale correctly when displayed on my 3840x2160 monitor. Why I am mentioning this? Simple: the argument that 'no one can run games at 4KUHD' is utter nonsense, and, I do not mention this for my fellow gurus, I mention this anyone reading this from an outside source who may have this ancient and fragmented opinion from the 1990's... Enjoy your spreadsheets and, buy some shares in Microsoft, because they are releasing AI into Microsoft Office 365 and it will change the whole godamn planet. ♥

In terms of 240Hz OLED vs 360Hz TN and it's suitability for high refresh rate gaming, then my point of reference for my earlier statement that 240Hz OLED matched or exceeded 360Hz TN was due to a post by Mark from Blurbusters (the founder of Blurbusters): "....the new 240Hz OLEDs is clearer than a 360Hz LCDs (smaller refresh rate difference multiple). This is because the LCD GtG can overwhelm smaller refresh rate difference multiples." https://forums.guru3d.com/threads/a-500hz-refresh-rate-nvidia-g-sync-compatible-gaming-lcd-is-in-the-works.443155/page-3#post-6020961 So in terms of motion blur (image clarity during motion) a 240Hz OLED is better than a 360Hz TN. Of course with the 360Hz TN assuming you're running at 360fps then the input lag is less for your mouse, so that's one advantage of running 360fps vs 240fps. But I'm talking about motion blur (image clarity during motion).

I think that on page 8 the Power Consumption In Watt table for White 100% Brightness was shown twice by accident i.s.o the one for Black 100%. Also I think that the RTX 4070; 2560x2440 table on page 9 was also not intended to be shown.

don't know about 360hz TN but they sure can't beat a working 120hz BFI TN I know I sent my asus 240hz oled back at 240fps it's close but as soon as you drop around 100 it becomes blurry, and it's nowhere near as sharp as BFI in motion https://www.testufo.com/framerates#count=3&background=stars&pps=1920 I see all 3 individuals one black pixels of the eyes at that speed BFI > all (because the problem isn't the monitor it's the human brain you need something to reset it to remove the blur we create) also not only is it still picture sharp but running 1440p@240fps is not something you want, your pc becomes noticeably hot and uses more watts raising fps is not the way and testufo site hinted at a future "bfi" oled I didn't read the article but you can't have it on oled because there's no backlight to strobe meanwhile there's a new BFI in the works by nvidia https://blurbusters.com/nvidia-announces-ulmb-2-improved-motion-blur-reduction/ if they can make BFI work without the ugly inverse ghosting (which I don't have by random luck or because I have I quote "ULMB 2 resurrects an algorithm that was originally used for LightBoost over ten years ago" my monitor is 11 years old) gaming oleds are done, except for the black, but blurry perfect black I learned isn't worth losing BFI nothing is
