Acer XF270HU 1440 IPS 144 Hz Adaptive Sync Thread - Page 48

The XF270HU is a terrible monitor all around IMO.
which is a damn shame, because right now (IIRC) its the only existing 2560x1440 144hz IPS Freesync monitor that supports the full 40-144Hz Freesync range

both FS2735 & MG279Q are either 35-90 Freesync OR 56-144 Freesync


while for Gsync (same specs) you have the beauty that is XB271HU (30-165) .. and even the PG279Q, lottery that it is

Most of the issues come from the fact that it doesn't really support FreeSync natively within that range, you're better off using the MG279Q, you could then change the range to 56-144 FPS since the lower end of the freesync range doesn't really matter at all thanks to LFC.

Or you could go with one of the best of all the IPS monitors, the Eizo FS2735 which is a true 56-144Hz monitor, its got two modes on the VRR Scaler, G.Sync or FreeSync it doesn't get better than this monitor.

Im still stubborn in that I dont want to rely on LFC (or the Nvidia equivalent) and want a broader native Gsync/Freesync range


and I will start considering Eizo FS2735 as soon as it drops below $1200 / 1100EUR tongue.gif

The XF270HU is a terrible monitor all around IMO.

is there a HUGE difference with overdrive on vs off @ 144hz >?

Oh yes. The XB270HU uses the same panel, and it goes from 11.3 ms average response time (144 Hz with no overdrive) to 5.9 ms (144 Hz overdrive on normal). Source is TFTCentral.

At 144 Hz, response time needs to be under 6.94 ms otherwise it will be a blurry mess. Without overdrive, these 144 Hz IPS monitors will be far above that usually.

These flaws of the XF270HU are really bad enough to the point where it should be considered dysfunctional. Anyone considering it should just go with the BenQ XL2730z instead in my opinion.

To get 144hz with this monitor, do we have to use Freesync? In other words, is 144hz attainable by using an Nvidia cad with this display?
post #477 of 863
Yes, you will get 144 Hz with an Nvidia card. You just can't use FreeSync.

Thanks. I've had the Dell S2716DG which is G-sync but a TN panel for a week now and I'm considering returning it to buy this Acer IPS display.

If you have a NVIDIA card you should seriously stick with a G-SYNC/ULMB monitor to take advantage of those technologies. Also it's not like these IPS displays are a world apart from TN, unless you don't sit at a head-on angle.

Anyone running three of these in Eyefinity?  Been thinking about it for my sim rig.
