Running on TV woes

I am having trouble getting my Pi4 to run on an HDMI TV, I have tried two separate TVs, multiple HDMI cables and 2 different HDMI to micro converters. It has worked in the past but only inconsistently, I can sometimes make it work by removing and reinserting but inconsistently, until I give up for a month and try again. But it's not useful if I can only get it running after futzing with it for 45 minutes first.

Relevant info:

Group CEA has 4 modes:
           mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
  (prefer) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
           mode 95: 3840x2160 @ 30Hz 16:9, clock:297MHz progressive
           mode 97: 3840x2160 @ 60Hz 16:9, clock:594MHz progressive
Group DMT has 1 modes:
           mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive

/boot/config.txt

hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16
hdmi_drive=2

Anything else I'm missing? hdmi_safe=1 I've tried both on and off, OFF (commented out) seems to work sometimes. Other inconsistent problems I've had is the screen is black rather than "no signal" and a scratching sound comes out. Or Retropie's menus are up but there's lots of vertical green lines.
