After seeing an S2133 in person, I noticed two things.
First, the scaling on the S2133 might not be what people claim it is. 800×600 looked a little bit blurry, just like how it appears on my S2134. Most people probably wouldn’t notice or care, but if you’re sensitive to this kind of bilinear interpolation blur, it’s definitely there. My S2134 has the same slight softness in 800x600 stretched to full screen. I can confirm now that 800x600 is not integer scaled both on the S2133 and S2134.
A comment under this YouTube video confirms this as well:

Question:
Have you tried it without emulation on real retro hardware? Like 486 with DOS or Pentium with Windows 98?
I'm curios how 320x200 DOS games would look and what options you have in the OSD to adjust the picture, like stretch, 1:1 with black borders etc?
Also 640x480 and 800x600 games in Windows, thanks!
Answer:
I got lazy but I checked the screen size settings in the OSD. There's full screen, enlarged, and normal. I put the monitor in 800x600 resolution and in normal mode, it puts 800x600 right in the center of the screen with black borders all around. Full screen stretches it up to 1600x1200 and is a little blurry it seems like. Enlarged is the same way. Not sure if that helps but that's all that's in there in regards to picture adjustment. I use this for emulation and GOG games so it's always in 1600x1200 resolution
However, there is a workaround for this. You need to use an external scaler that's capable of scaling 800x600 to 1600x1200 and use that resolution on the S2133/S2134.
Second, the monitor accepts 70Hz in Text mode/VGA mode 13h but the output is triple-buffered. There’s actually no true 70Hz operation. That didn't surprise me, since 70Hz is usually beyond the technical limits of most IPS panels. I noticed it while playing Raptor where there was a slight judder.
Unfortunately, there is no solution/workaround for this. You can't overclock the pixel clock because the monitor's firmware doesn't allow you to do this.
Despite this limitation, the S2133 and S2134 are still among the best monitors you can own for DOS gaming and retro computing.
The S2134 has a slight edge (500 cd/m² and 1800:1 versus 420 cd/m² and 1500:1 on the S2133) but that's about it.
