Analog vector display to HDMI

Category: Hardware
Product Number: AD7091R-2

I have an old oscilloscope that is equipped with a CRT screen. I am trying to replace this CRT display with an OLED one with HDMI input.
I noticed that the X/Y vector signals at the entrance to the video stage are +/- 13V. I chose AD7091R-2 for ADC, conditioning the signals with AD8606 OP (as in the CN-0335 example). For video processing I want to use R PI4 (because it has an integrated HDMI interface). Do you think this approach is ok or is there a simpler one?
