ensete I just checked the default ICC profile for the monitor, it is from BenQ. Not sure if that is making a difference for me. I can test it later by switching it to Dell.

Regarding the FPS, I just find out that older versions of chrome has a built in FPS counter. So I installed an old version chrome and turned on the FPS counter, most time it shows less than 10 FPS. Very often it is less than 5 (see attached picture). For watching online video, it is 24-30 FPS. What is more confusing is that these numbers are very different than what MSI afterburner gives me. MSI afterburner shows a stable number ranging from 45-50 while chrome FPS counter shows <10 at the same time.

    I would suspect the Chrome Frame Rate counter is counting how many frames needs to get drawn. It's only drawing a new frame when something changes, hence low FPS when you are just looking at text and flat images

    Try switching it to the Windows default (I think it is sRG😎 and see if that matters

      ensete Same thing with Windows aero display as well.

            JTL Not sure if I get this. So chrome FPS counter is counting the number of frames needed to generate chrome contents. What about the FPS from MSI afterburner? Both are on at the same time with the counter-strike game window minimized. Is the total number of frames rendered by the graphics card equal to the sum of FPS from chrome and MSI afterburner? Thanks.

                Jerry Pretty much, but Chrome and Windows aero are only rendering frames when needed, while the game is rendering frames constantly.

                    JTL I see. I noticed that in the game, the FPS is very stable ranging from 73-75. Even when I don't move in the game, the scene is still, nothing moves, the FPS is also between 73-75. The graphics card is constantly rendering frames even though it is not needed in the game. Not sure if there is a way to make the graphics render frames constantly in chrome or windows aero.

                        Jerry Like I said, it's PWM + response/image retention/etc i.e. motion. PWM is only half the equation.

                        I just picked up another Dell S2415H. 25% brightness and in a pitch black room my eyes feel as good as CCFL LCD monitor. Static text and motion. Intel graphics. You may want to look into the Dell S2715H if you need that size.

                            train44 Glad to hear that you find a solution. I may try the Dell monitors later. Looks like you are ok with intel graphics card. I found that integrated cards are no good for me. My HP desktop arrived a few days ago with AMD integrated graphics (the discrete NVidia has not been installed yet). It gave me instant headaches, the same feeling I had with intel graphics card. MUCH worse than my current XPS8910 desktop with discrete NVidia card. Now I tend to believe that my XPS8910 desktop with nvidia card and BenQ monitor is working well for me. The headaches I am getting is probably due to other reasons because I have to look at coworker's laptops during meetings from time to time and look at TV at home when my kids are watching. It is really difficult to control those things. I need more time to confirm that.

                              To come back to the topic...

                              Just came home from sinuses and nasal septum surgery. I'll give you all an update after my recovering process.

                                hey. I think its to early at the moment to give any feedback to you. I'm not fully revored yet. It will take some time till the mucosa will totrally heal.

                                    Harrison

                                    Hey, to give you an short update to come back to my theory. During the nasal septum surgery a chronical sinusitis was found and also removed. So this fact is maybe really a thing, cause some of you also mentionend problems in this area.

                                      I've had bad TMJ problems for years. There isn't much I can eat. After MRI last year it was found that my left TMJ is locked and the disc is slipped in the right TMJ. It needs surgery.

                                      When I open my mouth my mandible moves diagonally and deviates heavily to one side. It's pretty messed up. Caused me a lot of ear problems too.

                                      Hello again. Nearly two months ago I had my nasal septum surgery with additional removal of a chronical sinusitis. I'm still no fully recovered yet und moreover another small surgery is necessary to remove a synechia (Gewbebrücke?) in my right nose.
                                      Yesterday I've tested Samsung 4k 40 inch 6079. Still eyestrain (but not so heavy) and dizzyness. Didn't know if acclimatisation process or same problem as before.

                                      what's TMJ? I grind my teeth all the time. Dentist told me I was losing the sharp part of my fangs when I was a teenager.

                                        ctsai89 You're TMJ is the joint where your jaw meets your skull. Everyone has one (well, two actually)

                                        TMJ disorder is when the nerves in that area become pinched/inflamed and cause issues such as bruxism (grinindg teeth), referred facial pain, and other issues.

                                          I cant believe noone has commented on OP's statement that he is planning to get brain surgery to fix this!? amygdalectomy? is that done through the nose?

                                          Jerry at 30FPS, a game blacks out/erases the whole screen and redraws it 30x per second. web browsers/windows just change the colors of the individual pixels as needed.. plus pwm/temporal dithering

                                            add me to the teeth grinding list. interesting
