Asus ROG Swift PG258Q Monitor Review

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Gamma Response

The PG258Q’s default gamma tracking caused us some initial concerns. The small spike at 10% isn’t a big deal but the huge dive from 70-90% is. This will cause major detail loss through much of the brightness range, and it has a major impact on quality. Color will look bright and saturated, but many fine textures will simply look monochromatic. This is an area that needs to be right, especially when you’re talking about an FHD monitor.

The fix lies in the Contrast control. Our patterns showed us it was set too high by default. Dropping the value to 41 brings color detail back and smooths out the gamma trace. It still runs slightly above the line for the most part, but that’s a tiny issue. Gamma presets are spaced too far apart to achieve an ideal 2.2 average, but we’re satisfied with our result. You’ll see the impact on color in the next set of charts.

Comparisons

With calibration, the PG258Q posts a solid mid-pack result in our gamma tests. As we’ve stated in previous reviews, gamma is the key to everything important when judging image quality. Getting it right means maximizing perceived contrast and color detail no matter what the content. When it’s wrong, those crucial elements suffer.

    I just don't get it. How can you leave the contrast (arguably the most importante feature on a screen after the resolution) out of the first page of the article? I couldn't care less about the bezel width, but please, state the contrast!

    G-Sync, no thanks.

    No wonder this thing is $600.

    Have fun paying the Nvidia tax.

    1080P, *sigh* who wants this anymore! Get me a 4K monitor at 30-32" with good specs and G-Sync that isn't $4000.

    Because that's the reality of GPUs at the moment. GPUs can get you a solid 4K/60 or a solid 1080p/144. You're not going to get 4K/144 in any modern games on any PC at the moment (unless you're only playing 20-year-old games). So there's not a lot of sense in wanting to invest in a 4K/144 monitor now, only in anticipation of when GPUs can finally push that many pixels, because you'll be wasting the monitor while you wait, and when such GPUs finally do arrive, the monitors will be better and cheaper.

    Do we know if this monitor is 3dVision capable?

    I would assume so, but I've learned some very expensive lessons by making purchases based on assumptions. : /

    The reason you won't get it is because the GPU's won't do it, not because the games won't. Game developers want to make more realistic games but the GPU's are lagging way behind. Nvidia hasn't had any real competition for many years so there was no need for them to push to 4K gaming at 144Hz or higher. I am hoping AMD's cards will force Nvidia to get off their buts as it seems the consumers aren't going to pull their money from Nvidia until Nvidia gets back on the ball.

    I agree with AHNILATED! DSTARR3 says, "Because that's the reality of GPUs at the moment". I say let's have some serious change! Asus and Nvidia are "milking the cow" with these old relics. Everything is now going 4K, 6K and 8K. It's time to stop milking the cow and people's wallets and put out the new technology. It's 2017, not 1980. We all know the new tech is already here.

    Based on the performance bump we saw from the 1080 Ti, I don't think it's fair to say that nVidia's slouching when it comes to GPU performance. Pricing, sure, they could use more competition. But something like 4K/144 is a seriously enormous amount of processing to do. The DisplayPort and HDMI interfaces themselves had to be updated to transfer that much data. I'm amazed we got 4K/60 out of GPUs as quickly as we did. Give it another generation and we should be hovering around 4K/144. But you ask why there's no 4K/144 gaming monitors coming out yet, and this is why. There aren't any 4K/144 GPUs out yet, either. And it's not because any particular company is stagnating. It's because pushing that many pixels to a monitor is a huge, huge task.

    I use an Eizo EV 2336W. It has incredibly accurate and incredibly deep and vidid colors right out of the box. It also has a very deep picture and for an IPS screen very deep blacks. And to top it all off, it has extremely nice viewing angles, no color-shifts and it retains a ton of brightness at very steep angles. Motion performance is very OK for a 60 Hz screen.

    My current hardware isn't really capable of producing more than a reliable 1080p60. (GTX 970, i5-4590). So I see no reason to switch to a higher res screen or higher refresh rate screen.
