Hello !
I have a Siglent SDS1104X-E , no issue with it, but this DHO with Android inside and this user interface seems to be really great

But I have a question about the 256 level intensity grading.
I have seen some reviews, starting by Dave one's

and it seems to me that the grading is not very good, compare with my Siglent.
Most of the time, I see big yellow color on waveform, without any grading

Here are some pictures I have made with my Siglent, compared to the Dave's opening video of this topic

What do you think ? Is there a kind of bug on the graphical output display of the Rigol ?
Also, while I was making the screenshots, I have found that the Rigol has only 10 divisions on the time axes , whereas the Siglent shows 14.
So on the 2 first screenshot, we can see more of the signal on the Siglent than on the Rigol
