Monitor talk is crazy. In this modern era we have a choice between 4K panels, cheap Korean 1440p monitors, panels that cover wide gamuts those that refresh at 30 Hz, 60 Hz, 120 Hz and 144 Hz, as well as TN/VA/IPS panels with all the variants therein. The issue comes when putting as many of these features together - typically IPS panels at higher refresh rates are hard to come by, whereas TN panels can lack the wide viewing angles and color reproduction. So by saying that ASUS are paring a 27” 2560x1440 display with a high refresh rate and NVIDIA G-Sync, we open our arms to this kind of evolution.
Anand reviewed G-Sync last year, and while it is the closest adaptive refresh technology to market, it does have its competitors. The ROG Swift PG278Q is going to be available from July, and should bring more G-Sync into the market. While other specifications are thin on the ground from the press release, we are inquiring into a more detailed list of data points for the monitor. The PG278Q also comes with a dedicated Turbo Key to allow users to adjust refresh rates on the fly from 60 Hz to 120 Hz to 144 Hz with one button, rather than adjusting the on-screen display. ASUS is quoting a 1ms GTG response time, with a 6mm bezel, VESA wall mount, a large range of stand adjustment, 1 DP port, two USB 3.0 ports and a 5-way joystick for the OSD.
ASUS expects the PG278Q to be in the $800 region, with a full release in late July.
Why is the display TN rather than IPS/PVA/MVA, etc?
Not all TN’s are made the same: the premium panel used in the PG278Q is of very high quality. IPS panels (and their derivatives like PVA/MVA etc) are not suitable for a multitude of reasons: 1) the response rate is simply not fast enough to react to the active change in refresh rate and 2) Current panels available cannot reliably achieve >60Hz without significantly affecting the quality of the image. IGZO technology (and LTPS – low temperature polysilicon – likewise) – yields 100′s of times faster electron mobility versus standard amorphous silicon panels – and thus can provide a response rate comparable to TN (up to 60Hz currently), but, however desirable this technology is, it is still currently cost prohibitively for many PC gaming enthusiasts at this moment, which is why ROG has used a better priceerformance, high quality TN panel.
