I got HP Omen 15 2021 version with 3070 (G-Sync, the cheaper 3060 variety does not support G-sync). It came with AUO82ED panel, not LG (there is panel lottery unfortunately, even 2020 version has this option). The panel itself is unpleasant, an issue that I believe is separate from OS/GPU temporal dithering issue based on my subjective experience. I have some dithering laptops which does not feel like this screen.

Strain is reduced in Windows 10 1507, but so far unable to get Nvidia adapter working (OS requirements, ini mod may help, but so far latest success stories with notebook were only with 20xx and Win 7, but it’s also possible to add in a newer adapter in an older driver, apparently. I have to do more experimentation).

The take away for me is that this laptop did not disable modern Windows 10 strain for me.

It’s hard for me to evaluate the Nvidia adapter with this modern Windows 10 complication, and frankly I dislike the panel.

Edit: Actually I will compare discrete vs hybrid modes anyway and compare intensity of strain

Edit2: On Reddit someone reported strain with this panel on the Omen 15 2020. Really too bad about the panel lottery.

Answering my own question. I found the model number as AUO82ED which is from a company called AU Optronics, and not LG (LGD05C0) that some people have with HP Omen 15-dc1058. Should I be concerned? (Bought refurbished) Been getting eye strain everyday. Can someone with HP Omen 15 confirm their display type?

    After final testing, the HP Omen 15 is not good for me. There is strong pain inside of known good OS, and occurring in both Hybrid and Discrete modes. Whatever is going on here must be fairly strong for me to experience such a terrible migraine after testing. The dud panel hypothesis just doesn't sit well with me; there is something else here. The MUX switch and G-SYNC are not my cure. I am heading to a full e-ink solution now, as I see any other hardware solution is a dead end for me, and the situation is only getting worse.

        NedLud I am a software programmer (i.e. tech savvy) and i can tell you that that pdf does give you steps to disable temporal dithering on macs. However, i don't know whether they work - i don't have a mac so i can't test them. Sorry if this isn't helpful.

            logixoul I would love to know if this works on current MacBooks. Their video output gives me near instant discomfort.

              NedLud A question - for PCs, does disabling/uninstalling the the integrated GPU in the Device Manager help stop the Dithering by forcing the OS to use the outboard GPU?

              On almost all laptops the discrete GPU (ie Nvidia / AMD) always passes its output to the integrated GPU (ie Intel / Ryzen) to be displayed on screen. So the integrated GPU has the final say on what dithering or processing takes place.

              When you disable the integrated graphics card in device manager, Windows reverts to a basic driver to do this task, which often looks easier on the eyews, but lacks any power saving features or anything like the power that the GPU would have with the correct driver activated.

              Sorry to hear that. Don't suppose you have tried the exact model that I did? I've honestly not used a computer like it in terms of comfort: HP Omen 15-ek0005na

              Surely that's worth trying before going to the e-ink route?

                  highradio I’ve just bought a Alienware m15 r6 laptop with gsync. Please advise what I need to do to make it usable. Do I need to disable the intel graphics in device manager?

                      JonnyT Hi @JonnyT - the laptop you have bought has Nvidia Advanced Optimus which allows you to connect the laptop display directly to the discrete GPU. Follow the steps here to use the Nvidia GPU Only:

                      NVIDIA Advanced Optimus Overview | NVIDIA (custhelp.com)

                      This is probably your best shot at making it comfortable to use. Remember symptoms can take a few days to settle back down for most people on here. Good luck!

                          si_edgey thanks so much. Is the Optimus feature good to allow me to do this or have I made a mistake? I specifically went for a gsync one based on previous comments.

                          It also says the following. Would the following be the case even if I’ve selected the discrete mode only? Ie will this disabling only work if my laptop is plugged in? If I disable intel in device manager would that help things or be unnecessary?

                          ‘The display will not switch to discrete GPU in the following scenarios -

                          • The display will not switch to discrete GPU if the application in allow list is a DirectX9 application.

                          • The display will not switch to discrete GPU if there is a DirectX9 application already running.

                          • The display will not switch to discrete GPU if the system is running in battery mode (DC)

                          • The display will not switch to discrete GPU if there are any external monitors connected to the system

                          • The display will not switch to discrete GPU if an external-GPU (eGPU) is connected to the system.

                              Edit: This was incorrect information.

                              You will know the laptop is in Discrete GPU (Nvidia-only) mode because the Intel graphics will not be present in the device manager. There will be nothing to disable if it’s set up correctly.

                              Those conditions you posted are only valid when in the Automatically Select mode. When in “Nvidia GPU only” mode, the Nvidia GPU is always used.

                              Go into the Nvidia Control panel, then to Manage Display Modes, then select “NVIDIA GPU only”. If you do this the Intel graphics will not appear in the device manager.

                                  Just to confirm, is this 100% accurate for Advanced Optimus? It is for a standard MUX switcher but I was wondering if because AO allows you to switch without restarting perhaps the Intel would still show?

                                  Either way, it definitely bypasses the Intel graphics altogether @JonnyT.

                                      degen thanks so much guys. Praying this makes the machine usable for me and solves everything. Somehow I can’t believe it will be this simple after everything I’ve tried- but I’ll keep positive!

                                          That is my memory of using the Lenovo Legion 5, that using the Nvidia control panel to discrete mode was like using the switch in BIOS. You’re right though, I can’t be 100% sure. I hope I didn’t give bad advice.

                                          @JonnyT

                                          I am wondering how you set up your display mode settings in the Nvidia control panel, and what is the result in the device manager. Did you change to Nvidia GPU only in the Nvidia Control Panel? Are both Intel and Nvidia present in the device manager, or just Nvidia?

                                              degen the laptop is arriving on Wednesday so I’ll let you know!

                                                  So it has arrived!

                                                  I managed to set it as Nvadia GPU only in the Nvadia display settings. However, in control panel it still has the Intel UHD graphics listed and enabled. With it like this I can change brightness still.

                                                  Do I need to disable the Intel UHD there as well? Doing so means I can't change brightness . Is it necessary for me to disable it in device manager as well or can I trust that selecting is in nvadia will do the job ?

                                                          JonnyT My statement about it being removed from the device manager is incorrect!

                                                          If you want to make 100% sure you are using the Nvidia graphics, you can boot into the BIOS and set it there. I read your machine has the option to do that (hopefully I’m not wrong on that count!).

                                                          Turn this off. According to Dell manual it’s in the Display subsection.

                                                              degen thank you so much for looking into this for me.
                                                              I’ll do that in the bios.
                                                              Do I have to disable it in device manager as well or leave it enabled there?

                                                                  JonnyT You can leave it enabled in the device manager. This setting in the BIOS should actually remove Intel graphics from the device manager (for real this time, lol).

                                                                      JonnyT

                                                                      degen app I went into bios and turned off the hybrid option you explained. The only difference I notice compared with turning it off through nvadia direct is that the machine is noisier (fan comes on and off- won’t go onto quiet mode). It’s still enabled in device manager. I can disable it for what it’s worth but then I can’t adjust brightness.
