You can see it on a thermal camera with a high resolution sensor from China (not the ITAR limited US tech).

Got a link? This sounds handy.

Thermal Master P3: 25fps, 256x192, manual focus

Looks like it's improved even further - I'm seeing that model listed with 512x384 resolution, and it's $300 on Amazon.

Pretty incredible! I felt like I was getting an amazing deal when I paid about $1000 15 years ago for a FLIR E4 that I could flash into an E8. I might finally retire that in favour of one of these.

That's the software upscaled size, not the real resolution. Typical distortions of East Asian marketing.

I would be amused if the actual reason for upscaling is that a 256x192 display is hard to source and that the firmware is partially shared between models with a display and models without one.

It connects to a cell phone for display so the image is scaled either way. The issue is how the chosen algorithm may be adding non-existent detail or not. If you disable the enhancement you get nearest-neighbor. The true sensor size is all that really matters. Flir has nothing in this segment that comes close to that.
