| Linux: using xrandr to display only a segment of the screen |

Since I moved pretty much all my retrogaming/emulation activity to linux, I see and learn new things every day...
Yesterday I came across this post:
https://www.reddit.com/r/crtgaming/comme..._on_a_pvm/
I had no idea xrandr was able to feed a predefined segment of a video-output to a monitor.
Code: xrandr --output VGA1 --scale-from 320x240 --pos 1x1
With my intel GPU I'm using Super Resolutions (mostly 2560x240) and often times I see the output-image is scaled out of proportions when running apps like desktops, emulationstation gui, scummvm etc.
What I did is switching to a super resolution and then run the proposed code to correct the issue.
I was excited to realize that it worked out of the box and the image on my crt looked great.
Now I guess there has to be a drawback using this method - there's got to be, because nobody would use super resolutions instead, right?
Could it be that this method may cause vsync and/or tearing issues?
Since I only tested it with mostly static scenarios like scummvm, maldita castilla for linux and the lxde desktop I haven't seen any issues.
So, let me rephrase the question...
If I was able to create a perfect 320x240@60Hz (or ANY other!) output on my crt with this method, why would I bother to use super resolutions?
I think a super resolution is only needed in the first place to prepare the canvas in terms of height.. Using the segmented output I could create any width I could think of. I have to admit, I have no idea how refresh rates are handled within this concept.
Maybe I'm wrong about this - could somebody please enlighten me?

My employer (a newspaper company) upgraded their office PC's and is selling off their old hardware.
It's a HP Elite 8000 ultra small formfactor:
- Core2Duo 3,16 GHz, E8500
- 4 GB DDR3 Ram
- 250 GB HDD, 7200 RPM
- Intel GMA-4 GPU
- 6 * USB 2.0, 1 * VGA, 1 * LAN, 1 * Audio, 2 * PS/2, 1 * Displayport
- Dimensions: 25 x 25 x 7 cm, Weight: 3 KG
The System is pretty much ideal for a PC-to-CRT setup.
They are selling these off for 30€, if anybody wants to get one I can arrange shipping etc.
I'm located near Bielefeld, DE.

| N64 cores won't change resolution |

Hi, @alphanu
neither of N64 cores (parallel, mupen64plus and mupen64plus-next) are switching to native resolutions. They render only at the desktop resolution, 640x480 in my case. I'm on windows 10 using CRTEmudriver and NATIVE 15khz settings on mm4crt. Also, I have these modelines installed with vmmaker for n64:
384 x 288 @ 60.000000 n64
480 x 360 @ 60.000000 n64
640 x 222 @ 60.000000 n64
400 x 440 @ 60.000000 n64
When using the regular ReatroArch build, they switch only to 320x240, no matter the game.

I have an issue on windows 7 using retroarch 1.7.6 where when i launch a game and exit from it, the desktop resolution is not restored
Is that a setting i have to enable somewhere?
My desktop is on 640x480 @ 60hz
Also i notice that i have what sound like crackled sound in most games and emulators in tetrarch, using FBalpha latest, game libretto latest and also in genesis fx plus
My machine should be able to handle the audio i believe :
windows 7
core i7 with 8GB ram
HD5450 radeon with emu driver
SSD disk
Mame 0.206 with groovymame is also installed on this same machine and works great (it's a version with portaudio using d3d9ex)
I attached my current retroarch.cfg file
