BloodyHell619 What model motherboard do you have? Try flashing the original release bios version to it and if the release bios doesnt fix it flash a version of the bios that has a release date as close as possible to the release date of the graphics card or the date of the vbios. If your motherboard model doesnt have a lot of bios version to select from then save a copy of your GPU's original vbios and use the GOP update tool to change the GOP version inside the vbios file and flash it to see if fixed the issue. Use "nvflash64.exe --version romnamehere.rom" to check which GOP version your vbios has and select one that is the same size as the original to add into the vbios file.

@JTL I do want to pickup a lossless capture card but the only model that seems to be lossless is the DVI2PCIe, i wanted to check if there are other lossless PCI-e capture cards available but if not i will pickup DVI2PCIe to get some actual captures of a bad setup and good setup.

      Jack One thing the DVI2PCIe card can do that others cannot (at least easily) is emulate arbitrary EDID data from another display. If different EDID data has bearing on what GPUs do is an open question but I certainly consider leaving the opportunity open for investigation a good thing.

      Only thing I dislike about it is it requires either a Windows driver, or a distribution specific Linux driver, so it isn't ideal. VideoDiff currently works best under Linux, but optimizations in the future could be done for Windows.

        Sunspark If one could demonstrate the same GPU rendering "good" or "bad" output just by virtue of firmware changes and empirically measure the differences between them I certainly consider that potential for research.

            JTL Only with the caveat that there are other systems that are safe to fall back on should something go wrong, as is currently happening with BloodyHell619 where they have alleged that whatever is touched turns into coal. They only have the one system. If Jack has multiple systems, then why not sure.

              JTL I think the problem is not the picture itself or its structure. The problem is how these frames are delivered to the monitor. According to my sensations in those configurations when there is discomfort of the eyes I start to feel flickering of the screen. But the funny thing is that this flickering is not confirmed by the pencil test or the camera. These tests as it seems to me exclude only the problem of flickering of the monitor backlight but not flickering of rendering.

                  CepheiHR8938 I haven't seen anyone with issues with newer NVIDIA cards attempt any lossless capture of the display output, so if anyone is able to do it, it will be an interesting test.

                    smilem The author of the topic just needs to read reviews on his monitor. It says that Dell UP2720Q is actually 8bit + FRC. Dithering (FRS) is forced to output 10bit. Even if there is a "True 10-bit" panel. There are no such problems on the cheaper BenQ EW2780U.

                    Based on the declared number of shades reproduced, it was possible to conclude that both monitors are capable of operating in 10-bit mode. But is that really the case? Not really.

                    Dell UP2720Q does this through the use of dithering (FRC) and, given the expanded color gamut of the device, this is a necessary measure.

                    The BenQ EW2780U monitor is much simpler: the 10-bit mode appeared in it only because of support for one of the HDR standards, but in reality, more than 8 bits are not required to provide high-quality color reproduction for its matrix with standard color gamut. This is exactly how the native mode of operation of the device is set and it is on it that you should stop. In other words, it makes no sense to use 10bit mode on the EW2780U.

                        Still testing some other motherboard platforms, but i was unable to get my RTX A4000 to work without strain on my Z490. I even tested it with a lossless capture card and the card itself doesnt dither in the BIOS. If i swap over to a Quadro RTX 4000 or K4200 the strain is gone.

                        Thats the first review ive seen mention the UP2720Q is 8bit+2bit FRC, several other reviews and Dell themselves claims its true 10bit. In my case though the monitor is not the problem since i have several configurations which i can use this monitor strain free. The EW2780U is 8bit+2bit FRC but that review is saying the +2bit FRC only comes into play when displaying HDR. Are they trying to say the UP2720Q is using FRC even at 8bit?

                              AlanSmith Wow thats crazy so both Dell and Eizo are lying about their "10-bit" panels being true 10-bit? I heard rumors that the UP2720Q uses the same panel as the CS2740 and the coincidence that both these "10-bit" panel use forced dithering in even in 8bit mode seems to confirm that. Eizo themselves claim its true 10bit though or do you think they really are lying?

                                So how to know what site is telling the truth then?

                                So the gigabyte m28u seems to meet the requirements of my good specs "list":

                                I am wondering if you could comment on whether or not the matte finish is light matte or strong matte with "haze".
                                I like the light matte or halfway solution talked about here: https://pcmonitors.info/articles/matte-vs-glossy-monitors/

                                However others are saying the m28u is bad? https://ledstrain.org/d/1928-recommendations-for-new-monitor/71
