Hey,
I'm the perfect person to answer your question because I got my Asus XG279Q about a week ago and I got it as an upgrade from my PG279Q (the PG279Q is basically identical to the VG27AQ).
First, let me say that I love my PG279Q. The picture quality of my PG279Q is simply amazing. Whether it's the brightness, contrast, colors, refresh rate, build quality and aestetics of the monitor, all of the boxes are checked and get an A+....except for one thing. That one thing is the response time.
The response time of the PG279Q is actually pretty good, comparatively speaking, but it's not quite good enough for me. I only noticed the blurring when I was really really looking for it, particularly only in competitive fist person shooters. But the slower response time was noticeable.
The 1ms advertised response time on the XG279Q was the main selling point for me because I loved everything about my PG279Q except for the slightly slower response time. Well, the XG279Q hits it out of the park because it plays and feels like a TN panel in terms of the responsiveness but maintains the amazing picture quality of my PG279Q.
And I didn't think it would be possible but the picture quality on my new XG279Q actually surpasses that of my PG279Q. The colors are richer and the contrast has improved too, in my opinion.
Hopefully this helps. I think that the XG279Q is about to become one of the most popular and highly rated monitors on the market once more people get their hands on it
I'm so glad I found this forum, first of all, you must be stacking to go from the PG279Q to the XG279Q. I started PC gaming in 2017, I didn't even have a regular PC, my household wasn't too wealthy. When I was first researching monitors the PG279Q was the 1 I wanted because of the 1440p 144hz IPS G-Sync. I don't know the details, or really care about colors and brightness, I haven't advanced to that level yet.
Anyway, the price at the time was around £700, and I couldn't bring my self to get it, and I liked the idea of having 3 monitors instead, so I got 3 of the Samsung 1080p 60hz IPS which were £200 each. For 3 years of Black Fridays the cheapest I saw that monitor for was £550. For the last week I've been trying to buy it, but it's not in stock anywhere, some sites say its the end of life. So I reached new monitors which had the specs, (I only wanted Samsung or Asus).
I also only just found out about G-Sync Compatible, I still dont fully understand the difference, I researched it and it has apparently been out for years, but only last year, Asus did the test, so I'm hella confused. So I'm left with a choice of the XG279Q and the VG27AQ.
I glanced at the VG27AQ the specs seem fine for me. I looked up why it's much cheaper and people say 'TUF' is 'entry-level' even though the specs were good I didn't want to take a chance with it in case there's something bad happens in the future
So after years of waiting, I finally brought myself a gaming monitor, the XG279Q. On Youtube though, I can't find any reviews of it, just a couple of foreign videos. Luckily I found you. Comparing the XG279Q to the PG279Q. The PG279Q is true G-sync, however, the XG279Q has HDR, Slimmer bezels, 1ms response and can reach 170hz. With your XG279Q, what G-sync differences do you notice from the PG279Q, and are there any other differences you know/ noticed between them.
Many Thanks
