Any Archer with 2560x1440 monitors out there?

graysky · 2013-07-16 01:21:04

Started using a new 27" Asus PB278Q this evening @ 2560x1440. Gotta say, it's a pretty big jump from my old 24" 1920x1080. I'm finding it tough to acclimate to the higher resolution and am wondering if I need to create a custom /etc/X11/xorg.conf.d/90-monitor.conf or something to make it look less far away. Do these numbers look right?

% xdpyinfo | grep -B2 resolution
screen #0:
  dimensions:    2560x1440 pixels (677x381 millimeters)
  resolution:    96x96 dots per inch

% xrandr --query | grep 2560
Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 32767 x 32767
DP2 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
   2560x1440      60.0*+

I am no expert, but perhaps you can try increasing the dpi.

@x33a - I'd like to but the using the following as my /etc/X11/xorg.conf.d/90-monitor.conf has no effect on the dpi:

Section "Monitor"
  Identifier "Monitor0"
  Option  "DPI" "100x100"
EndSection

After restarting X:

% xdpyinfo | grep -B1 dot
  dimensions:    2560x1440 pixels (677x381 millimeters)
  resolution:    96x96 dots per inch

I have 2560x1440 too (and also a 1080x1920, yes vertical). I also use have 96x96 dots per inch and for me it's lovely. However it could be that I'd prefer a different amount of DPI, I never thought to experiment. I'm happy with this level of DPI and won't experiment yet at least. However you're of course free to configure your system as you like.

@SidK - Would be nice to try, but from what I'm finding on our own wiki, it isn't possible. Seems as though X is set to 96x96 with no overrides.

https://wiki.archlinux.org/index.php/Xo … ze_and_DPI

See my post #3 above wherein I attempted to modify the dpi per the next section in the wiki but to no avail.

x33a · 2013-07-16 16:21:09

I read somewhere that you can pass the dpi option to startx. Try something like:

startx /usr/bin/<WM> -- :1 -dpi 100

Note: This will start another X server so you can experiment around.

Thanks, I actually just now discovered:

% xrandr --dpi 100x100

Logout/backin and now

% xdpyinfo | grep -B1 dot
  dimensions:    2560x1440 pixels (677x381 millimeters)
  resolution:    100x100 dots per inch

Dunno how to make it permanent ... 100x100 looks really bad

2560x1440@27=108.79 PPI

Correct... does that mean that I need to manually adjust the output to 109x109 dpi? Is a PPI = DPI?

cybertorture · 2013-07-16 16:51:03

@graysky yes in theory, in practice find what suits you most

P.P. Point per inch and dot per inch is the same yes

Since I am running xfce4, I found that Settings>Appearance>Fonts allows me a custom DPI setting which seems to be 'permanent' compared to the `xrandr --dpi 109x109` but 109 DPI looks pretty darn odd!

x33a · 2013-07-16 16:56:35

Keep experimenting around until you find what really suits you.

2560x1440 here on my debian system with XFCE and I use the Settings>Appearance>Fonts DPI at 109. I always like to match PPI=DPI, then adjust the font & point size. You might as well let the all the actual pixels fire to form your fonts. Looks a lot sharper in my opinion.

Another benefit is that applications with physical distance measurements, (i.e. gimp, libreoffice), display exactly spacially. Just hold up an 8.5" x 11" sheet of paper to Libreoffice Writer at 100% zoom when PPI=DPI, and you'll see it's 1:1

On my Arch laptop with i3wm, I add to my ~/.xinitrc:

xrandr --dpi 140

as it's 1440x900 and 12.1". I typically use 6pt and 7pt fonts on that system. As others have said, whatever looks good to you is what matters.

I found it best to set the display size in xorg and let it automatically set the DPI.

graysky · 2013-07-18 19:13:54

Thanks for the replies all. Using the native setting of 108 set in Settings>Appearance>Fonts. Guess it'll take some time.
@boast - Xorg will default to 96x96 for everything according to the wiki I linked above.
