Re: Acer announces 144hz IPS 1440p G-SYNC! [XB270HU, XG270HU

I got a question about 144hz ips monitor.
Ips monitors have usually a response time of 5-8ms. I thought that is why we didn't see any 120hz ips monitors up today. Is this new kind of ips panel with low response time? Otherwise it is not a good idea to force standard ips panels to higher refresh ...

Re: Acer XB270HA 27" 1080p 144hz

I made a mistake and it seems there are RGB sliders so I made a recalibration for 6500K kelvin white point. I'm posting all settings

Brightness 6 (for 40nt luminance)
Contrast 50
Gamma 2.2
Color temp - User - Red 46, Green 41, Blue 50

Re: Acer XB270HA 27" 1080p 144hz

Yes, contrast is 50 for that profile.
Since there is no RGB sliders for this monitor, calibrated white point is also 6900K-7000K for that profile.
But I found a way to manipulate white point by increasing contrast to 56-57 which makes white point 6500K. But it also increases average color accuracy ...

Re: Acer XB270HA 27" 1080p 144hz

I'm not a photographer or color expert but everyone needs a colorimeter for decent colors on their monitors. Especially for multi monitor setups because color differences become apparent. These colorimeters make colors look good for even oldest cheapest monitors.
Especially when people compare TN ...

Re: Acer XB270HA 27" 1080p 144hz

I just recently bought this monitor. I would like to share my findings.
I already have multi-monitor setup for work (not for gaming). These monitor's are Dell U2913WM and old Samsung 226BW. I also have a Spyder 4 elite colorimeter to keep these monitor's colors consistent across them

I calibrated ...
