pi@raspiredNOOBS131 ~ $ tvservice -s
state 0x120016 [DVI DMT (16) RGB full 4:3], 1024x768 @ 60Hz, progressive

3-port HDMI Switch --> HDMI to VGA Converter --> 2-Port USB KVM Switch --> TV's VGA Input

Device Name is that of the 3-port HDMI Switch:

pi@raspiblueS8Gb ~ $ tvservice -n
device_name=LTM-LONTIUM

Again a reduced set of resolutions are available:

pi@raspiblueS8Gb ~ $ tvservice -m DMT
Group DMT has 3 modes:
           mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
           mode 9: 800x600 @ 60Hz 4:3, clock:40MHz progressive
           mode 16: 1024x768 @ 60Hz 4:3, clock:65MHz progressive

pi@raspiblueS8Gb ~ $ tvservice -m CEA
Group CEA has 9 modes:
           mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
           mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
           mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
  (native) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
  (prefer) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
           mode 17: 720x576 @ 50Hz 4:3, clock:27MHz progressive
           mode 18: 720x576 @ 50Hz 16:9, clock:27MHz progressive
           mode 19: 1280x720 @ 50Hz 16:9, clock:74MHz progressive
           mode 31: 1920x1080 @ 50Hz 16:9, clock:148MHz progressive

pi@raspiblueS8Gb ~ $ tvservice -s
state 0x12001a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60Hz, progressive

Again optimise by editing config.txt:

...
# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720
framebuffer_width=1024
framebuffer_height=768

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1
hdmi_group=2
hdmi_mode=16
...

pi@raspiblueS8Gb ~ $ tvservice -s
state 0x120016 [DVI DMT (16) RGB full 4:3], 1024x768 @ 60Hz, progressive

T.V. with Composite Video Input only

(Yellow RCA "AV" connection or SCART + Adapter)

Resolution is fixed ...

pi@raspiNOOBS132 ~ $ tvservice -s
state 0x80001 [PAL 4:3], 720x576 @ 50Hz, interlaced

... but overscan can be optimised by editing config.txt:

...
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
overscan_left=12
overscan_right=-12
overscan_top=8
overscan_bottom=8
...
# NOOBS Auto-generated Settings:
hdmi_ignore_hotplug=1
sdtv_mode=2
