ASUS ROG SWIFT PG258Q, 25 Inch (24.5 Inch) FHD (1920 x 1080) eSport Gaming Monitor, 1 ms, Up to 240 Hz, DP, HDMI, USB 3.0, G-SYNC

From being a 60hz user for years and then jumping to 240hz monitor I noticed an enormous improvement in every aspect of this monitor. There's a common fallacy where people say the difference in 144hz to 240hz is very minimal. To me as I said the 60hz to 240hz jump was extremely noticeable but my when my brother came in to check out my new monitor (He's a 144hz user) he said the difference to him is too subtle. I do think a purchase like this is less worth it in you're already on 144hz but for someone like me who was on the low end for so many years then its definitely a worthwhile investment. Absolutely amazing for gaming and I would recommend. Only thing is if you're setting up this monitor by yourself it can be quite awkward to do so unless you have loads of space. Once the monitor is all set up it's nothing less than fantastic.No tearing, sharp colours and seriously smooth movement with the mouse.

This monitor is noticably fast. The refresh rate, response time and Gsync make it a very powerful asset for games like CS:GO, Battlefield etc making for an incredibly smooth experience. Do you need 240hz over 120Hz? Unless you only play CS:GO, probably not because most games won’t perform at that high frame rate consistently. But when you look at the market you’ll be lucky to get 120Hz gsync monitor much cheaper than this one at the moment. Only thing I don’t like Is the contrast ratio of TN panels but that’s nothing specific to this monitor in question, it’s 95% of “gaming” monitors. Seen some reports of “bad backlight bleed” but outside of the normal spill around the edges I’ve not had any issues there. Anything other than an OLED panel with have a certainly level of backlight bleed. The monitor it’s self is very robust and has a great build quality. So far I’d say worth the money.

240fps looks amazing. I was a 4k gamer before that and heard all the pros play with high refresh rate. I played 4k for over 2 years now but was curious what exactly 240fps looks like.It is amazing, even though I had a downgrade in resolution, the frame rate has quadrupled. Its like driving a car that goes 60mph and driving a car that goes 240mph.You will easily predict where your opponents go in matches. In gears of war 4 horde mode, playing as the sniper is so easy to hit headshots even when an enemy is running sideways far away from me which is near impossible on 60 fps.Mind you also need hardware to support the high refresh rate. I have a gtx 1060 and a i5 6600k. I have to be honest, my frames are usually around the 140-160 mark but it feels so smooth and responsive that I am going to upgrade to a gtx 1080 so I can get a consistent near 200fps or more. I play my games on full HD, low graphic settings to get the most out of the frame rate. If you are a pc gamer or looking to become one, from someone who has had a high res and a high refresh rate monitor, I 100% encourage you to go for a lower res with a high refresh rate monitor.

Motion clarity at 240Hz is a significant improvement over 144Hz for very fast paced games (in particular first-person-shooters). For a game like Overwatch, playing Tracer and blinking around at 240hz gives you less difficulty in keeping track of targets as you whizz about, moving the mouse very fast and not having to wait around as long for the image to clear up to see what's going on.However, that fluidity and speed comes at a cost (compared to my previous 144Hz 4ms IPS monitor): Vertical lines can appear on the screen during motion. I've read online that these lines are "pixel inversion artifacts". The effect can be quite distracting, especially if you're not used to seeing the lines. They also take away from the clarity at times.The effect is more pronounced the lower the refresh rate (and depending on what's being displayed). It's less apparent in say Cuphead, and very obvious in something like PUBG or Tekken 7. You can also see the issue at higher refresh rates, even up to 240hz, but they don't appear as frequently.For a £500 1080p TN monitor, the main thing this has going for it is the motion clarity, and that's been affected by this issue.I ordered a replacement monitor (both sold and delivered by Amazon) and it had the same issue unfortunately.No dead pixels that I've spotted on either monitor. Colours aren't as bad as I've heard elsewhere. It looks fine. If the reds are really strong you're probably in FPS mode.Both boxes also showed signs of having been opened before. One had a corner of the white protective plastic foam snapped on the opposite side from where I opened the box (it snaps pretty easy when you try to pull the monitor out as it's pretty tight - on the side your pulling it from anyway!).One order had both UK and US(?) power cables, another only had US cables.--UPDATE 19th Dec 2017-- I have to say I am rarely bothered or even notice the vertical lines while playing now - but I have only been playing Overwatch really, which runs at 200+ frames/s so I don't see the lines very often anyway. In fact I actually ended up forgetting about it, which I thought was impossible when I first got the monitor. Changing the score from 3* to 4*.240Hz does make a big difference in motion clarity when moving the mouse horizontally very fast, which I do quite often. TBH if they released a 300Hz monitor down the line I'd probably want to upgrade!Also, something I hadn't mentioned: the monitor stand actually takes quite a lot of space as the stand's feet point inward and the mouse cord even catches on it quite often. I bought a monitor arm to use with this and I highly recommend it: "Invision® PC Monitor Arm – Ergonomic Gas-Assisted Full Motion Single Arm Desktop Mount for 17–27" " On sale for £25ish instead of 60. The gas-assisted adjustment is fantastic and feels very high quality and sturdy. Surprising for the price. Very easy to install. Might have an issue with the cable management they give you the option of using (need long cables or a rather close PC). But it's very flexible and has made a great improvement to my setup and comfort.

EDIT: after owning this monitor for a week it now has quite a large dead pixel on the screen, very visible and distracting on white screens. After spending £500 this isn't really what i expectThe main issue with the other monitors seems to be backlight bleeding from IPS panels, but on this 24.5 inch TN panel right now it's perfect, 240hz as advertised. The only issue for me is the stand is a little big, a little bit unnecessary but I just need to buy a bigger desk really. You can turn the display light off underneath the monitor so not sure why I've seen people complaining about that. And that's about all really, colour quality is better than my 60hz benq monitor. Overall just a very nice monitor

Imagine quality is so bad but that is what you get with a TFT Panel. In games the picture quality is ok but its awful for everything else.
