If you’re buying a high definition 4K gaming monitor right now, the 27-inch category is by far the best investment category. 4K monitors of this size offer the best performance and are the most affordable, making them great purchases for a wide variety of use cases. But it’s also important to get something out of this current generation of 4K panels, or you’ll be missing out on key features.
One of the key features is HDMI 2.1. Only the latest 4K monitors include HDMI 2.1, and to be honest, I wouldn’t buy something that doesn’t have it. HDMI 2.1 is required for 4K with refresh rates above 60Hz, so if you have a computer that you want to connect via HDMI, or more importantly, a current generation game console, then HDMI 2.1 is essential. We didn’t look at a lot of older 4K monitors because they didn’t pass this basic test.
The best 27 ” 4K monitor is actually 28 ” in size and it is Gigabyte M28U… The M28U is usually available for between $ 600 and $ 650, making it one of the most affordable 4K 144Hz displays you can buy. This monitor supports HDMI 2.1, but crucially, it is not your run-of-the-mill 4K contender with mid-range performance; The Innolux M28U panel is one of the best we have ever seen in this category.
The Gigabyte M28U has a very good response time with an average transition of 4ms at 144Hz. It also has good performance over the entire refresh range. For those using adaptive sync’s variable refresh rate, you don’t need to tweak overload settings to get the best experience. This IPS monitor delivers speeds in the ideal range for the latest generation of IPS panels, so there’s nothing fun about motion performance, and it’s complemented by a great strobe backlight that works in conjunction with adaptive sync. This is a better package than you get with some of our previous 4K recommendations like the LG 27GN950 and 27GP950.
Thanks to the IPS panel, the color quality is high, as well as the viewing angles – a wide color gamut, although not as wide as that of the best modern monitors. The factory calibration is above average, there is a good sRGB mode for everyday use, and the contrast is typical of an IPS panel, there are no particular problems there. To top it off, Gigabyte includes a KVM switch and a height-adjustable stand, which are great additions.
Also consider …
For those buying a 4K monitor for use with the PlayStation 5, we recommend the Asus TUF Gaming VG28UQL1A. Asus is very similar to the M28U, it is not that good and tends to be more expensive (around $ 800), however it has more HDMI 2.1 bandwidth, which is more compatible with PS5, which gives it an edge.
Plus, if you need full DCI-P3 coverage for content creation, the Gigabyte M28U doesn’t have the best P3 coverage, even though it’s a wide gamut monitor. In this case, the more expensive LG 27GP950 will suit you.
There are several other options that are very similar to the Gigabyte M28U because they use the same 28-inch Innolux 4K 144Hz IPS panel, some of which might be worth considering depending on prices in your area. Also, note that the M28U has terrible HDR performance – it’s not an HDR monitor at all – so if you want the right HDR, this isn’t the monitor for you. Keep in mind that getting true HDR will cost you 2-3x the manufacturer’s suggested retail price for this monitor. Don’t be fooled by fake HDR monitors that add this capability to their specs without the required hardware.
