Flat!
Donny's wonderful CRT "imperfect" recreations on the older bridges suit the designs of those monitors very well, and in no way detract from their aesthetic to my eyes.
Or to put it bluntly, the CRT imperfections on the older bridges don't look like errors, whereas they do very much look like mistakes with this era of LCARS.
It's because the TNG LCARS aesthetic has thick, matching, intentionally aligned linear bits.
This is exactly how I feel as well. The CRTs of my TWOK and TUC-era efforts fit aesthetically with those sets and I had no qualms employing them in those cases. However, it just feels....
off in the TNG-era to still use them, as greater efforts were taken in TNG onward to conceal the fact that they were indeed using CRTs. As stated before, many of those insert or close-up shots of the monitors were replaced with flat-panel graphics either on set or in-post. So it feels more correct to abandon the CRTs in favor of flat-panels here.
It depends on your goal - are you replicating the sets or modelling the ship? I've always understood it to be the latter.
My goal was always to "model the ship" but I've historically treated on-screen accuracy as canon in regards to my sets. So, in my head-canon, if there was a CRT used on-set, in-universe they were using a 23rd century analogy to a CRT monitor, for whatever reason.
But here, as I venture into the TNG-era, I want to go with what was aesthetically intended, especially wanting to preserve the flow of the brushed gold details into the monitor displays. As an artist who knows that Okuda and Co were probably bothered that the intended flow was broken by the constraints of the time, it just feels
good to see that intended flow fully realized here.
While the nostalgic part of me loves the CRT look, doing it flat panel seems like it will make your life somewhat easier, so let's go with that.
It's really no harder to depict them as CRTs now that I've done the preliminary material setup and modeled the mesh. I was going to make some additional refinements to the CRTs if I went forward with them, but the bulk of the work has already been done to employ them.
There is a
third option here, as
@Lt. Washburn suggested:
do both. I could set up a toggle that allows me (or an eventual end-user

) to switch between displaying the monitors as flat or CRTs. And that would just require a small bit of data setup on my end.
