Replacing OLED screen on an Agilent U1253A Multimeter
wraper:
As I said it has the wrong controller - SSD1305 instead of required SSD1303 https://aliexpress.com/item/3256801202021227.html So you can spare the effort of soldering it uselessly.

I solder some of the most demanding prototype 200Gbaud data circuits at work, soldering this display on will take about 1 minute, then with a short 15 sec video I will get my money back, otherwise I dont get my $25 back, worth it for a minute of my time.
I am pretty sure you are correct, its the wrong display. Nowhere in my link does it say what model number this display has, but it says its compatible with my meter, so I should be covered for a refund.
--Oz--:
@wraper, you were correct, haha. Refund in process. I do like the blue color over the yellow/green. Next to get/build the flip board. Anyone selling them? Or I will just order and build a couple, anyone else need one?

Weird, I have tried twice to post pictures of the pcb adapter I plan on using and the post does not show up,,,,,?

Actually with this version of the display I think it is enough to flip it and it will be "pixel perfect" only the other display requires the pixel shift.
So you can use this really simple fix with an eeprom only:
