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.

Viewing Angles

The Gigabyte M27Q has typical IPS viewing angles with a greenish red tint visible at 45 degrees  to the sides. Light reduction is only about 20%, which is better than many monitors we’ve tested. From the top, things look a little blue with a 30% light falloff and a slight reduction in gamma. Overall, the M27Q’s performance in this test is very good.

Screen Uniformity

Our M27Q sample had slightly visible hotspots in the two lower corners. We could see them in a black field pattern with the lights turned off but not when there was some ambient light. Brighter patterns showed no issues. Color uniformity was excellent with no visible change from edge to edge.

Pixel Response & Input Lag

Click here to read up on our pixel response and input lag testing procedures.

The M27Q is a very fast monitor, even among its speedy competition. Its 6ms draw time is typical for a 165 or 170 Hz screen, although our 165 Hz examples from Pixio, Gigabyte and ViewSonic took 7ms.

But the big news is the low input lag. With a total time of just 22ms, the M27Q ranks as one of the fastest monitors we’ve tested. This puts the M27Q on par with a 240 Hz screen for total lag, though a 240 Hz monitor will produce visibly better motion resolution.

    The monitor stand is very flat. It's very easy to put things like your keyboard there if you need more deskspace in a moment.

    Specially because I need great versatile monitor. I don't game pretty much 10% of my pc usage mostly forums, reading texts, and yt..
    So i need monitor that is good in all of that,
    it seems to me that dell s27dgf is my choice?

    In the market for a new monitor used for gaming (PS5), reading, and photo editing. Been using an Eizo till now but want a larger more versatile screen. Been eyeing the M27Q for quite some time since it seem to strike a perfect blend of good performance and price. However, this test showed the cheaper G27QC better on all fronts but input lag (6 vs 7 ms). is there something i overlook or why would I get the M27 over the G27?
