How to change to lower screen resolution of different monitor? (Solved)

I've been using one of my old PC with an Acer X213W monitor (22 inch).
ASUS M4A78LT-M LE motherboard with onboard VGA/DVI (ATI Radeon 3000).
Code: Select all
Screen 0: minimum 640 x 400, current 1400 x 1050, maximum 1400 x 1050
xrandr: Failed to get size of gamma for output default
default connected 1400x1050+0+0 0mm x 0mm
1400x1050 0.00*
640x480 0.00
720x400 0.00
I want to swap monitor with a Phillips 241S (24 in).
Got resolutions choice of
Code: Select all
Screen 0: minimum 640 x 400, current 640 x 480, maximum 720 x 480
xrandr: Failed to get size of gamma for output default
default connected 640x480+0+0 0mm x 0mm
640x480 0.00*
720x400 0.00
720x480 0.00
Am I stuck with the Acer with this Radeon?
Buster DDOG, Bullseye DDOG, Bookworm DDOG - same result.
I know both the Acer or Phillips have more choices when connected to a better GPU.
Eg. this is the Phillips when connected to GTX-670.
Code: Select all

I installed Stretch DDOG, to see any difference.
Got these choices on the Phillips.

It turns out the Acer get even better resolution when using Stretch.
But I can live with 1280 x 1024 for what I need from this old PC with Phillips.
So, for now I will use Stretch until I figure out more.
BTW - Someone changed the topic title of initial post. I can't tell who did, no note.
I changed it to 'back' here, since I don't think I was trying to 'change to lower screen resolution'.
Trying to get better 'max resolution' on the Phillips monitor is more what I am after.
On paper (specs) - Phillips 241S is better than Acer X213W.

A little background of what I'm doing this for.
I have many SCSI U320 HDDs, 300GB-500GB each, salvaged from servers (boat anchors) long ago.
It's not like I'm short of storage, but I don't feel like sending them for landfill yet.
And this mid-tower old PC have 12 bays. So, I have been using this to archive more junk.
I'm moving the PC from where the Acer monitor is to where the Phillips monitor is, hence I encountered this issue.
But it looks like, I can 'downgrade' to Stretch and 'close' this thread.
A little side-track (FYI) while I was doing this.
I tested EasyOS (v541) on this PC (with Phillips monitor). And it gives the 'best' resolution choices so far.
Unfortunately for me, EasyOS has no Adaptec SCSI support OOTB (?).
DDOG has it - all I did was to stick in the Adaptec card and the disks are accessible.
I'll ask in EasyOS forum section if I feel like tinkering further.

Apparently, I was not done tinkering with this. 
I'm glad that I tried @rcrsn51 starter kit.
DebLive_daedalus-6109-amd64.iso
It's closest to Fred's DDOG, so less learning curve for me.
And it took care of the screen resolution issue that I'm having.

The difference may be that the starter-kit has xserver-xorg-input-libinput installed (probably a regular mklive build hasn't, it has xserver-xorg-input-evdev).
(edit: now you mention the starter-kit, I remember a discussion from years ago where @rcrsn51 plead for including libinput)
(good chance this is the reason for your resolution issue and installing it on DDog will fix it, not really sure though)

Ah...thank you for this info Fred.
I was wondering why and what was the diff.
I did test your minimum DE builds (XFCE4, JWM), but X did not start.
After reading https://wiki.debian.org/AtiHowTo
then I added xserver-xorg-video-radeon, xserver-xorg-video-r128 one by one, but no joy.
I will try again later and report.

I tested with fresh bullseye DDOG and bookworm DDOG, installed xserver-xorg-input-libinput
No change, with or without removing xserver-xorg-input-evdev, so that was not it.
I looked at the starter kit mklive build log.
Found firmware-amd-graphics.
Tested DDOG again from fresh installed, added firmware-amd-graphics.
Happy days!
