Try lopping off a pixel or two in the x-direction. There is a problem with bounds checking since you can't fill a pixel partially (x length should be dividable by 3)
This is very early software from when I was prototyping.
Good afternoon, today I received this 10.1-inch screen with a resolution of 8K, and I started studying.
The screen connected to the Nvidia RTX 3060 video card via HDMI without any problems.
I set up a resolution of 2560 X 4320, 23 hertz, CVT with reduced flashing (there was a screenshot of the settings here, I did everything the same way)
I used your converter. The test table is 6919 X 4320 in size, the converted size is 2306 X 4320.
Then I opened the converted image on the screen in full-screen mode and please see what happened.
On the left side is the original template before conversion, on the right side is the final result on the screen.
In this topic there is a photo of a screen with the same table - everything is high-quality and smooth there. I have a different result.
I have prepared an image according to the PNG instructions of 8 bits in grayscale.
I managed to take a screenshot of the converter's operation - please take a look.
It is written in Cyrillic:
Unhandled exception, System.Runtime.....: A general error occurred in GDI+,
......\Program.cs:line 67
......\Program.cs:line 167
I also tried to output a photo that was in the archive (it has already been converted) - the result is the same as with the table.
Please tell me - what could be wrong?

Yes, I have now downloaded the converter again, tried it, and I got the same result, the images are converted, but in the same way.I've uploaded a new version of the utility. Can you try downloading again? I didn't include the shortcut, just drop the image you want to convert on the exe file. If it's working you can make your own shortcut.
Full screen mode is not enough. You have to make sure the pixels are displaying at 100%. It has to be exactly pixel for pixel.
Hello
i just would like to ask why a 16K Display does not work?
should i still buy a 8K Display or is there any news about altering the Resolutions.
Can i send the coverted pictures over an Raspberry and Linux to the driver board ?
Thanx
Maurizio
You can contact them on aliexpress and ask for a spec sheet, or just if it is 8 bit. Keep in mind it has rectangular pixels, so you are going to have to do a factored resize on the image in addition to the bitmapping. It's not quite 300dpi but the 16x20 prints I have made with the 8k lcd look fine.I’ve been following this thread and I’m considering making something to use in my Durst 8x10 enlarger.
Given there is a 12k display now available fairly cheap from sumopai - will your code work with that, or is it also 3bit like the 16k one?
Asking because the 12k looks like it would handle a bordered print on 16x20 paper which is my largest usual print size.
Thanks for the quick reply, maybe I’ll start with an 8k screen to get it working and understand the tech/code - then I’ll upsize if I need it. I have coded in the past but it’s a long time since I wrote anything that directly addresses device driversYou can contact them on aliexpress and ask for a spec sheet, or just if it is 8 bit.

You can download the exposure software here...Hi, I am so happy I found this post. I have being working with similar approach for over an year now, first using my mobile and later considering a similar display. I was about to order one from aliexpress. I have developed a program, with calibration capabilities. I think I'm exposing each tone on a slightly different manner, using only black/white pixels. I later saw that another guy was using a very similar approach as well and he used the monochromatic lcd with contact print, his project is also mentioned in this topic by another member. The generated tonal sequence on this program have many steps, and limited the exposure total time a lot due to refresh rate of the screen I was using. I wrote the software in java and on android environment so a google laptop or pc should be used. I wonder if now I just go the rp4 route if the software here is available for trial. I would gladly share my code as well if that is desired.
these microcontrollers
It's worth noting that the driving device only needs to be capable of 4k video output, not greater, because these mono displays use a bit of a hardware hack where colour channels are assigned to full pixels, so there is 3 times less data being transferred over the cable than the resolution of the display might suggest.

I found this card locally, is this the one you are using @avandesande ?
Fantastic!Making some small steps with '16k' lcd. For starters, it's not really 16k. its resolution is 11,154x6,230 adjusting for the rectangular pixels which is really slightly under 12k. However, that is enough to fully resolve the GFX50r output or a 60mp full frame camera. Still a ton of work to do to get this in the darkroom... I am going to incorporate resize into the application itself (a complex subject) and look into GPU acceleration. Probably several months out. The photo is a image that has been bitmapped to 3 bit. Dimensions are 11203 x 6192 and 1400 x 6192 after the mapping. I promised myself I wouldn't work on this but like the story of the scorpion and the frog I can't resist, not sure if I am the scorpion or the frog!
