    HDR does not work at all on macOS when using the adapter, and it defaults to YCbCr with no way to change to RGB without an EDID override.

    Burn-in is a non-issue. I used a B7 on the desktop with HDR always enabled at ~140 nits for years and didn't take a single protective measure. I left it on with static browser icons and taskbar for thousands of hours without any visible burn-in.

    I believe the GPU under macOS cannot handle tightened non-standard timings like 1440p 144 Hz and 8-bit RGB 4K 120 Hz over DisplayPort 1.4. 1440p monitors like the PG278Q are limited to 120 Hz. I filed a bug report and one of the engineers responded that it's not supported by the "hardware"...

    No, macOS doesn't support the 4K 120 Hz timings on this adapter, though you can see it in the EDID on macOS. Others have reported that it works fine in Boot Camp with the Radeon drivers. I have the exact adapter you linked. I have a 2019 MBP 16" running Big Sur.

    I have this adapter for my MacBook, but have no way of testing it on my 3090 without a DisplayPort to female USB-C adapter.

    Just received OTA firmware update 03.21.18 on my CX. The installation failed with "Software update cannot be applied to this TV". Now it doesn't detect the update anymore. It has a "Fine Tune Dark Areas" feature to partially correct raised blacks in VRR...

    Mind bending problem - Random restarts

    You need to repeatedly start and stop the test, not run the test continuously. Use different combinations of the AVX settings in Prime95.

    A pcie 3.0 M2 drive should work in a 4.0 slot right?

    The Gen 4 M.2 slot on your board is wired directly to the CPU and not the chipset. The 11th gen CPUs have 20 PCIe lanes, while 10th gen CPUs have only 16 PCIe lanes. So, the slot is not connected to your 10th gen CPU at all. Higher end motherboards may have a PCIe switch chip to share 16 lanes...

    Mind bending problem - Random restarts

    Spontaneous restarts without a BSOD could be the CPU crashing due to voltage changes between high & low load. It's possible the motherboard has default settings that don't follow Intel specifications and degraded the CPU, or has AVX ratios too high. You can test this in Prime95 with Small FFTs...

    GDDR5X vs. HBM vs. HBM2

    That's because Big Navi uses slower GDDR than Ampere, and Infinity Cache makes up for it. If the VRAM had the same performance as Ampere's, Infinity Cache would probably deliver a bigger performance uplift.

    BEWARE: WD Red Pro in desktop Use - Replacement suggestions?

    It could also be vibration. I had a particular PC case which killed a desktop class drive every few months in my 6x drive RAID array. The WD Red Pro has firmware optimized for high drive counts in a single chassis, but you never know. The desktop drives will definitely fail fast if stacked in a...

    GDDR5X vs. HBM vs. HBM2

    The performance difference is negligible compared to a bigger GPU with more shaders. Infinity Cache on Big Navi makes a bigger difference than HBM vs GDDR, at least in gaming. The difference in power and heat is a few watts - negligible compared to the GPU. Any GPU will be painfully slow in 4...

    My CX gets mild image retention after a few weeks if I use the Blank Screen screensaver rather than letting it power off. It clears up after powering it off.

    I use the CX 48" at a desk and ~4 feet is the minimum distance where it's not uncomfortable to my eyes & neck. It's equivalent to my 27" 4K Predator X27 at arm's length.

    150% scaling is the only real solution for text sharpness. It's the best compromise. At native resolution (3840x2160), Sharpness 10 seems to do nothing while higher values do sharpen the image. At 1080p, it pretty clear Sharpness 10 performs anti-aliasing and Sharpness 0 is neutral. This video...

    This is the correct appearance. The brightness is controlled with the HDR / SDR brightness balance slider in Windows, not OLED Light which must always be 100.

    The curves are arbitrarily decided by LG and don't follow a standard roll-off. There does exist the BT.2390 standard for tone mapping which madVR supports (when using HGIG mode). LG's 1000-nit curve is accurate up to 560 nits, and squeezes 560 - 1000 nits into 560 - 800 nits. LG's 4000-nit...

    Use the new AviSynth beta filter in SVP Pro in the installer, and uninstall ffdshow. It works with HDR in MPC-BE. You can also use mpv from the installer. Here is my mpv.conf. Exclusive mode audio must be disabled for Dolby Atmos for headphones to work in Windows. # # THIS FILE WILL BE...

    The 4000-nit curve results in reduced clipping, not more clipping, by reducing peak brightness and rolling off above 480 nits. Washed out colours are due to a broken decoder chain not reporting BT.2020 PQ - that has nothing to do with HDR.

    Passthrough of HDR metadata does not work in any player, period. You must use a HDR-aware renderer like madVR with MPC-BE to output BT.2020 PQ and manually set the HDMI signal parameters on the TV based on the content you're watching or the TV will use the wrong tone mapping curve. Alternatively...

    HDR metadata passthrough to the TV does not and has never worked on PC. When HDR mode is activated, the TV is permanently in the 4000 nit tone-mapping curve if DTM is off. You have to use the HDMI Signalling Override menu to set Mastering Peak to 1000 nits manually. Or just use HGIG mode if you...

    One of the filters in the playback chain is not reporting the metadata correctly. That's what it means when you see "best guess" in madVR. It could be a decoder, or intermediate video processing filter. MPC-HC is obsolete - use MPC-BE.

    Looking for 4TB SSD for games...not NVME.

    I wouldn't pay the same price as NVMe for an obsolete 4 TB SATA drive. The 4 TB Samsung SATA drives cost even more than NVMe. Upcoming games will be designed for 5000 MiB/s read and write speeds because of the consoles and your PC will fall behind. I would run the GPU at x8 and use a PCIe to...

    Use only NVCP to initially setup the cloned displays. Windows Display settings can result in software cloning with a performance hit. Once you've setup cloning with NVCP, you can use Win + P to toggle it without losing hardware cloning. You also need to match the refresh rates exactly down to...

    I posted the formula for it earlier. 0 is 80 nits and 10 is 120 nits. These are absolute values and are constant for any display that is calibrated correctly.

    Anyone still running an X99 Broadwell-E system?

    I had a 4820K at 4.6 GHz all-core. It's just too slow even for games like Dota 2. I got 50% more fps when upgrading to a 9900X with the same GTX 1080.

    It sounds like you're using fullscreen exclusive mode, or changing refreshing rates between 120 Hz and 119.8 Hz or something. I don't have any display resets with Alt + Tab or overlays in games, or in MPC-BE + madVR, unless I specifically use exclusive mode.

    The HDR / SDR brightness balance slider outputs absolute values in nits which does not change if the display tracks PQ accurately, which it should in HGIG mode at least. The peak brightness could have changed, but the slider maxes out at 480 nits. What you describe sounds like the entire PQ...
