Edit: It’s 30-100Hz, not 23-100Hz. The article has now been corrected.
It has long been rumored what the refresh rate of the best gaming monitor 2015, the Acer X34, would be. Well, it’s 75Hz, but hold on just yet. With the G-SYNC feature enabled, you can have the display’s refresh rate vary from 30Hz to an impressive 100Hz. That’s a very large range and much better than we had expected. The large upper limit is due to the fact that this monitor has its G-SYNC feature overclocked.
In comparison, the Acer XR341CK, which is basically the FreeSync version of this monitor, has a FreeSync range of 30-75Hz, which is also quite nice. It has long been rumored that both monitors would have a variable refresh rate (Adaptive Sync) range of 30-75Hz, but that is not true according to Acer. The 30-100Hz range is the correct one.
Now you might think, is the DisplayPort 1.2 standard able to refresh such a large resolution at 100Hz? Yes it is and it’s actually able to do it at 109Hz with a quality cable. G-SYNC does not work with any other standard than DisplayPort 1.2, so DisplayPort 1.3 or HDMI 2.0 (MHL) is not an option.
You can already pre-order the XR341CK (FreeSync) model right now, but the XR341CKA model is not for sale at the moment and is scheduled to be released by the end of August or the beginning of September. The price tag is expected to be around $1249. We’re very excited about this monitor!
Here’s the answer from Acer in case you wanted to see it yourself. They specify the refresh rate with HDMI and MHL, but with DisplayPort, which is a requirement for G-SYNC, has a minimum refresh rate is 30Hz.
Acer also confirmed it on Twitter:
@x3sphere The X34 supports 100Hz on G-sync mode.
