Hi Jac,
looks pretty good. Much better resolution than my Radiola TV. On your TV I'm sure you can probably read menus e.g. of VLC very clearly. That is a very nice vintage TV you have I just found
this web site where yours is actually pictured.
My dream TV would be to get an
E1 441 Line "Einheitsfernseher" but as only about 50 of them were ever built they are like gold dust and priced accordingly...
Cheers
