"No promises but I might have something similar for AMD graphics under Windows/OSX/Linux in the future. I've been busy but be rest assured I'm still working on it 😉"

This makes me very excited. Let us know if crowdsourcing some cash would help for prototyping and testing time.

    AGI I had never used a Mac before and I wonder...is Belkin 4K Mini DisplayPort to HDMI Cable what I need?

    I have never used Mac either. So I don't have the answer to your question.

    AGI Are you thinking of buying Yotaphone 2 or 3?

    I want to get a yotaphone 3, but a yotaphone 2 in good condition is also fine. Yotaphone is available on Ebay. https://www.ebay.com/itm/new-Yota-3-YotaPhone-3-64GB-Unlocked-Android-7-1-1-Mobile-cellphone-Ch-Versio-/163000905485?_trksid=p2385738.m4383.l4275.c10

            AGI I intend to connect to the Dasung the laptop I was given at work. It is a MacBook Air (13-inch, Early 2014). I had never used a Mac before and I wonder...is Belkin 4K Mini DisplayPort to HDMI Cable what I need?

            I think you might have some issues given intel GPU dithering and how the Dasung makes it visible. but I believe this is the right cable.

            Good luck!

                Aaaaarghhhhh, really? I wish my eyes were not so strained and I could go thru all the dithering-related posts on this site...I glanced on a thread where you, if I recall, show that for Nvidia cards it is possible to switch dithering off. Is that a feature only of a limited number of cards? Or not all computers use dithering? I use shared facilities and hence shared PCs. In my previous job I checked and all the monitors which I could tolerate were connected to PCs with non-Intel graphic cards. Coincidence?

                Thanks on the cable. Maybe it is not a bad idea to hear what Dasung has to comment on the likelihood of dithering...are not those our potential saviors? I trust they are among the few to be interested in hearing about our pain, not certainly Google or Intel.

                    It has no effect in some 9xx and all 10xx cards.

                    To be honest with you. I'm not sure if the dithering option under Linux ever did anything since I remember using older Nvidia cards just fine under Windows without needing to change anything.

                    Not a coincidence.

                        Thanks. After what happened between me and Android two weeks ago I am skeptic about being able to use the AMOLED side (which may also be employing PWM), so I do not see the point of investing 800 bucks for half phone :-(
                        Unfortunately Yotaphone 2 was on sale for USD 100 a couple of months ago and is now out of stock. That I would have considered buying at that price.
                        I hope someone will soon come up with a full e-ink phone at a reasonable price.

                            AGI yeah, agree. 800 bucks is a high price. I will just use the e-ink side of the phone.

                                Gurm i think it's like 'dither-rig' i.e. the thing you use to control your dithering

                                  Laptops probably used dithering for many years? Why is it suddenly a problem and only on new models for some people?

                                        reaganry is it easy to install? I can try, but it seems different than yotaphone.

                                              maybe because LED's have faster and more abrupt response times than CCFL's

                                                The backlight has ZERO to do with the dithering (unless it's an OLED), the dithering is a product of the panel and/or video card.

                                                    JTL yes, you are right. I confused it. The context was „Laptops probably used dithering for many years? Why is it suddenly a problem and only on new models for some people?”

                                                        AGI Did you ever get an answer to your resolution question? I recall that the only LED backlit laptop I used before this was a 2011 MBP 17" antiglare and run in a reduced resolution as I just wanted things larger. I never used it in native resolution. I don't have it anymore but recently tried a 15" version on native resolution and got terrible strain.

                                                        • AGI replied to this.

                                                            Lowering the resolution did not solve eye strain for me on desktops. Except when the low resolution was the result of using a generic video driver (Windows: "Standard VGA", Linux: "VESA"). Keep in mind that some (most?) modern graphics cards always output the display's native resolution by default, doing all the upscaling themselves instead of letting the desktop monitor handle it. They completely bypass the desktop monitor's scaling function this way. I am not sure how this is usually done in laptops.
