This is a TN panel and I came from a PVA panel that delivered somewhat better colors by default. However, I will say that as far as TN panels go, this one delivers decent enough colors after making some monitor tweaks. Another setting that I strongly recommend for this particular monitor is to go into the OSD menu and turn off the "deep power sleep" option that apparently caused lots of trouble for some people. The monitor will still go into low power mode and deactivate the backlight when I suspend the computer, so I guess that deep sleep isn't overly necessary.
First of all: WOW. I had heard about the advantages of higher refresh rates beyond 60 Hz, but you have to see it to believe it. The present windows & desktop wall effects that looked OK on my old 60Hz display now look incredibly smooth, and it's almost hard to go back to lower refresh rate displays now. The funny thing is that I've increased the pixel count on my display by 60% but I think the most noticeable improvement is to the temporal resolution with the higher refresh rates vs. the spatial resolution improvements.
Second of all: G-sync works under Linux. It's got a few rough edges compared to Windows since games have to be run in fullscreen (which I do anyway) and you need to suspend desktop compositing, but I've already run the Talos Principle and Borderlands 2 with the G-sync visual indicator showing up in the upper right hand corner for confirmation. I honestly don't know how much it helps, but its nice to know that there is support for this technology under Linux.
Oh, and I'm not even at 144Hz quite yet. It turns out my GTX-770 will drive 120 Hz just fine, but can't quite push 2560x1440 at the full 144Hz ( https://forums.geforce.com/default/topi ... -s2716dg-/ )
So uh yeah. Since my poor old GTX-770 won't do the full 144Hz I think it's TOTALLY time for an upgrade. How about a GTX-1080? Yeah, that'll push those extra 24 Hz ok. Upgrade Justified!
Linux handles the high refresh rates relatively well. For the physical GPU configuration, I just selected the refresh rate using nvidia-settings and then saved a custom X.org config file so that the correct refresh rate is used every time that I login. I use KDE Plasma 5, and it needs a little manual tweaking to get the desktop compositor rendering running at higher than 60 FPS, which is its normal default. You need to add two entries to the ~/.config/kwinrc file that I show below. After that, restart kwin and you *will* notice the difference.
Here are the settings for the ~/.config/kwinrc file. There will likely be additional entries under the [Compositing] header, just add these two extra entries, and modify based on your actual refresh rate:
Code: Select all
[Compositing]
MaxFPS=144
RefreshRate=120 # I can't go higher than 120 now, but this will go up to 144 when the video card can handle the higher refresh rate
