Have you ever ever questioned why 60Hz is the usual refresh price for shows? It began with analog TVs, then their CRT tubes have been repurposed into laptop displays. Then LCD displays arrived, however their gradual response instances meant that they could not actually go above 60Hz. Plus, 60Hz was ok, proper?
As PCs obtained extra highly effective they began enjoying movies – movies shot and edited utilizing TV gear, so 60Hz (interlaced, however let’s keep out of that rabbit gap). Quick-forwarding to right this moment, 60Hz continues to be seen because the “regular” refresh price, nevertheless, excessive refresh price (HRR) shows have gotten increasingly widespread on smartphones to the purpose the place they’re anticipated on something above the entry-level.
So right this moment’s story begins in 2017 with the Razer Phone. The purveyors of RGB-laden gaming {hardware} had acquired Nextbit a couple of months earlier. For many who do not keep in mind, the corporate was recognized for the Nextbit Robin, a “cloud-first” smartphone, which got here with solely 32GB of built-in storage and no microSD slot – you have been anticipated to make use of the 100GB cloud storage for information. If we’re being type we are able to say that the thought was forward of its time for 2015. Fortunately the Razer Cellphone did away with the cloud-first strategy – it had 64GB storage and a microSD slot, it was cutting-edge in different methods.
Razer Cellphone
The Razer Cellphone was outfitted with a 5.7″ IGZO IPS LCD that was fairly a sight once we first laid eyes on it in late 2017. This Sharp-made panel ran at 120Hz, double the refresh price of different telephones on the time.
Even higher, the panel obtained it proper out of the gate and supported variable refresh price (VRR). This allowed the show to adapt to the refresh price that the GPU might deal with, leading to a easy, tear-free expertise. As highly effective because the Adreno 540 contained in the Snapdragon 835 was, it could not actually preserve the FPS pegged at 120. And it did not must.
This was a 1440p show, by the way in which, sharper than some flagship shows right this moment. And it supported a large colour gamut, one thing that was simply beginning to achieve traction again then. The cherry on prime have been the front-facing stereo audio system that flanked the show – this was cellphone for gaming and multimedia and it let everybody know.
As is commonly the case, Sharp was an early adopter of latest tech (its personal tech on this case). The Sharp Aquos R Compact was introduced in October 2017 with a 4.9″ 1080p 120Hz display. Sharp had been delivery HRR shows to different producers even earlier than that, however none have been as well-known because the Razer.
The next 12 months Razer got here out with the second technology handset, the Razor Phone 2, although it looks like it used the identical panel, simply switching from Gorilla Glass 3 to GG5. The Razer brand on the again now had RGB lighting, although, which issues to that specific fan base.
Asus joined the sport with the unique Asus ROG Phone, nevertheless it had a special strategy. It opted for an AMOLED panel with a 90Hz refresh price – not a variable refresh price, although. And it had a decrease decision, 1080p (which was most likely extra sensible given the capabilities of the Snapdragon 845 GPU).

2019 is when excessive refresh price shows went mainstream – the Pixel 4 sequence had it, the OnePlus 7 sequence had it, as did the Oppo Reno3 Professional, Realme X2 Professional, Redmi K30, a Lenovo Z6 to call a couple of. A comparatively recent gaming cellphone sequence from ZTE, Pink Magic, additionally launched its first HRR telephones that 12 months.

Xiaomi Redmi K30 5G • Lenovo Z6 • ZTE nubia Pink Magic 3 • Asus ROG Cellphone II ZS660KL
Most of those telephones used AMOLED shows, although the Redmi K30 did have an LCD. And so they had one thing in widespread – they lacked variable refresh price help. This was one thing solely telephones outfitted with IGZO panels might do on the time and seeing how Razer had given up on the cellphone enterprise, that meant solely the occasional Sharp Aquos.
It took some time for VRR to return to smartphones and that got here as LTPO AMOLED panels began popping out of the manufacturing facility. These have been featured on a number of 2021 fashions from the standard suspects – Google, OnePlus, Oppo and Xiaomi, plus some vivo fashions.

Xiaomi 12 Professional • vivo iQOO 8 Professional • Apple iPhone 13 Professional Max
It is attainable to do VRR on non-LTPO shows, it is simply not environment friendly. In truth, that was the unique use case for the know-how (Apple used it on the Apple Watch Collection 4). Apple lastly joined the HRR social gathering with the iPhone 13 sequence final 12 months too, regardless of providing iPads with ProMotion shows (beginning with the second gen iPad Professional).
As we mentioned earlier, a HRR show is one thing taken with no consideration on trendy mid-rangers and particularly for flagships with 120Hz being the most typical quantity, although there are a couple of 90Hz fashions on the market too.
For essentially the most half it’s gaming telephones which are pushing greater. The Red Magic 5G was the primary to hit 144Hz in March 2020, then the Red Magic 6 obtained to 165Hz a 12 months later and that’s as excessive as smartphones have gotten for now.

Gaming displays and laptops now provide 240Hz, 300Hz, 360Hz and so forth, so we’ve little doubt that some gaming cellphone will go above 165Hz in the end. Whether or not that is truly helpful with a battery-powered GPU is one other query.
On the subject of refresh price, the cellphone’s interface is noticeably smoother at 90Hz, extra so on 120Hz after which issues begin to taper off. Gaming telephones need the bottom latency attainable to provide gamers higher response instances, so for them it is sensible to go for greater refresh charges.
For normal smartphone use, nevertheless, we guess that 120Hz would be the norm for a number of years. We expect that the main target can be on different enhancements, e.g. a wider adoption of variable refresh price panels (which actually assist with At all times On Shows, however with gaming too).
