How many of you use the Ditherig software from this website? https://kawamoto.no-ip.org/henteko/myapp_en.html I'm thinking of reaching out to the creator in the distant future and asking if he can make Ditherig work for the upcoming (2020 release) Intel discrete graphics cards. If we had a GoFundMe or similar to buy the guy a graphics card / pay for his time would anyone else be interested in contributing?

I never heard of this website before, thanks for sharing. I am in if there is to contribute!

AGI That's great, thanks. A bit of background on Ditherig, it turns off dithering functions for intel integrated graphics, newer chips only though. It really works too.

Seagull Actually I believe the developer tested it on earlier generations. I've used it on HD4000 and works. From the site: "This requires Windows XP or later. This requires Intel 6th generation graphics or later (e.g. Intel HD Graphics 3000, including Sandy Bridge, Ivy Bridge, Haswell, Silvermont, Broadwell, Airmont, Skylake, Kaby Lake, Goldmont, Coffee Lake, Goldmont Plus, Amber Lake and Whiskey Lake generations). I have checked behavior with the combinaion of Intel UHD Graphics 620 and NVIDIA GeForce MX150, Intel HD Graphics 515, Intel Iris Pro Graphics 5200 and Intel HD Graphics 4000."

Seagull A bit of background on Ditherig, it turns off dithering functions for intel integrated graphics, newer chips only though. It really works too. Would it work also with Intel HD Graphics 5000 1536 MB? But my laptop is a Mac. Is it correct the software works only on Windows? Thanks for "a bit of background". I saw some posts in the past about a dither software, but I could not catch up.

Count me in to help with funding. Intel Integrated Graphics is used in I would say at least two-thirds of most offices and consumer machines (unless using discreet graphics for gaming/CAD etc). If a proper dithering solution was achieved even just for Intel graphics it would 'unlock' a lot of machines to use. Also a Mac dithering tool would be a dream come true.

AGI AGI Would it work also with Intel HD Graphics 5000 1536 MB? But my laptop is a Mac. Is it correct the software works only on Windows? a) probably b) yes

I would gladly fund this. We should ask the one we fund to be open source.

All I can say is that if the Intel drivers are similar enough to the existing integrated GPUs (in terms of configuration) writing such a program should be trivial (for Windows and Linux)

JTL Why is Mac always out of the equation? Could you explain in a few words to a non-expert?

AGI Because it's harder (not impossible) to manipulate the driver code under OS X. If I worked for Apple, this would be easier, but alas I don't.

Ditherig Straw Poll

karut

Does this app work with Windows 11?

Edit: seems like: https://github.com/skawamoto0/ditherig/issues/4

Can someone confirm? My banding test image does not look all that different with it turned on.

asus389

I tried the most recent version in Windows 11 and it seemed to work. Not sure it completely solved my eye strain on windows but it did seem to change some effects of the GUI.

fisherking111

I installed this on windows 11, and it has destroyed my frame rate & my computer no longer detects my Dell S3422DWG monitor (says in Advanced display “Connected to Microsoft Basic Display Driver)

I just reinstalled the Dell Driver and still doesn’t work & I see no “uninstall” file in the Ditherig folder.

Please Help! 🙏

Ditherig does not install, you can simply delete de folder and reboot. Most likely in your case it is a coincidence.

even v2.2 does no work on win10 laptop with intel integrated graphics Acer V3-571G with 8bit IPS screen FHD 15.6" AUO B156HAN09.0

DisplaysShouldNotBeTVs

For the record, ditherig works on Lenovo IdeaPad Yoga 13" (2012 model, i7, HD 4000, Windows 8.1). After disabling dithering, color depth is surprisingly reduced effectively all the way to 6-bit and extremely heavy banding appears.

This computer was already very usable by default with only some slight eye strain, but after disabling dithering, there is near ZERO eye strain. It is now one of the most comfortable screens I've ever used.

DisplaysShouldNotBeTVs how about connected to a external monitor?

DisplaysShouldNotBeTVs

jordan It didn't seem to use dithering anyway when connected to an external monitor, regardless of the ditherig setting. Changing the setting wouldn't changing anything about my external monitor output, it always remained an 8-bit RGB signal.

All of the monitors I own have FRC so it's hard to tell, but I could only notice the monitor's own FRC pattern when moving my head. Usually when a HDMI signal uses temporal dithering (like on M1 Macs by default), I can see the two dither patterns clashing with each other on certain shades of color. However, the Lenovo's output looks just as clean (as an FRC monitor will allow you to get) as the clean signal you would get from a modified "Stillcolor-dither-disabled" M1 Mac.

I can confirm Ditherig works for me on a 13th gen Intel HP laptop. Effect is direct perceivable for me.

Hunter20 I can confirm Ditherig works for me on a 13th gen Intel HP laptop. Effect is direct perceivable for me.

it works, but dont eliminate flickering? what OS build you use?

Hunter20

simplex

Windows 11 22H2 build number 1702 (Laptop = HP Elitebook 860 G10 16inch)

Without Ditherig.exe the first image on this page flickers like crazy: http://www.lagom.nl/lcd-test/gradient.php

With Ditherig.exe installed flicker goes away. (difference is very visible with naked eye)

The Ditherig program didn't automatically detect my 13th gen intel iGPU, I had to choose "Identify GPU by questions.." to make it work.
