Jerry Thanks on your feedback and on this note

Jerry It will be the best if there is a HDMI 2.0 port on your laptop to use Dasung. Otherwise you will need a converter which may not give you full performance.

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?

Jerry I am also thinking about getting a yotaphone you mentioned in your other posts. It is pretty expensive on ebay (~$800).

Are you thinking of buying Yotaphone 2 or 3? I contacted Yotaphone via the form on their website a few times to know more about the best channels to buy but never heard back...

          "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.

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

            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

                    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.

                        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?

                                                      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?”

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.
