ACER XF270HUA Review: A revision of the ACER XF270HU with a frameless panel design. A Gaming Monitor with an excellent price-performance ratio.

Both are very different monitors and it depends on the content and other factors like your environment (pitch black room or a brighter environment etc). The Acer has a better color stability and no color shift issues while the Samsung has. In dark image content (Sci-Fi or Horror titles or even darker areas in games like Witcher 3 in a cave for example) the Samsung usually wins because of the contrast ratio. The farther away you sit from the CHG70 away, the better the overall image quality and less VA glow. Same applies to the Acer (fewer IPS glow when increasing the distance to the panel). Personally, I still would prefer IPS simply because of the color stability and combined with it the viewing angles, which are usually much harsher than on a TV for example, where a VA panel mostly wins on a TV (also because good TVs have a stronger contrast ratio than current VA monitors). 

You should check out my IPS vs VA (Viewsonic vs LG) comparison, this maybe can help.

Thanks, mate :) Yes the Samsungs VA glow is better than on the CFG73 and far better than on the HP Omen X35 for example. But the VA Glow still is visible and depending on the "individual person" still an issue 

I am really wondering why HDMI 2.0 works better for you :X

I am using basICColor mostly as well as DisplayCAL. BUT, ICC profiles are not really important (while most games do not read ICC profiles and it would only change the color temperature as well as gamma settings). Gamma + Color temperature + Brightness can be easily set within the OSD, so you do not really need to "calibrate" with software. You can use Windows calibration if you want a different gamma setting than offered in the OSD (:

Good to know, thanks.  I just could not notice that the image is darker when using HDMI, you're the first person from that I hear of that "problem". Will try to ask some owner of the Acer

I just did test DP (no HDMI) and I did not have any Ghosting issues tbh. I bought an RX580 just to test Freesync monitors :X But if HDMI works for you without any issues, then it should be still good without suffering from your mentioned issues. 

Thanks for letting me know, will try to update the review asap

Maybe.. It would be really awesome to own more graphics cards as a reviewer T_T Unfortunately obviously I cannot afford all those graphics cards to test Freesync issues within a specific line :/

Sounds really weird... Just wondering why you have such issues. Did you have also tried some older driver versions?

Yes, it is the same just that Freesync doesn't work as great as G-Sync because of variable refresh rates (especially on lower fps it can occur that you also will see some ghosting). Otherwise, on 144Hz it is perfect.
