You have sent those PCs that don't support Dolby Vision back to **** Leave the decision of whether or not the Dolby Vision mode switch is turned on to the user!

26100.4484（KB5060829）=26100.4482 (KB5060829，Release Preview channel)=26120.4250 (KB5060820)

OH NO ，What did you do? I understand why this happens - when HDR is enabled, it directly switches to Dolby Vision mode, but there is no Dolby Vision switch.Because I need to turn on the Dolby Vision PC switch in the LG C4 TV system. The Dolby Vision mode switch will appear in the Settings menu.

Now, not only have you snatched control of my LG C4 TV Dolby Vision PC, but you're also sending those TVs that don't support Dolby Vision back to ***. I would like to restate: The greening of those LG C2 TVs is not your fault due to the WIN update, but it is the fault of the LG OS. All you need to do is to prevent the device from automatically switching to Dolby Vision mode ! Leave the decision of whether or not the Dolby Vision mode switch is turned on to the user!

You guys turned on the Dolby Vision mode switch on TVs that don't support Dolby Vision PCs, and this is not a mistake, it's a surprise. Your mistake is to turn on automatically! It will automatically turn on every time you turn on your computer! There are a variety of devices that use Windows. You guys will never be able to take care of all the equipment!

Remove auto-open code. Keep the Dolby Vision mode switch for those that don't support TVs. Make it unturned on by default. This way, LGC2 users won't find the whole TV green to complain about the feedback center after the update. Even if the LGc2 user goes to HDR and turns on the Dolby Vision mode switch and turns green all of a sudden, he just needs to turn it off, because he knows what he turned on that causes it to turn green. It's all damn automatic switching, ruining everything!!!

Someone told me: It's not desirable to always enter the Dolby Vision mode every time the device is powered on. It should be based on the settings made during the last power-off. If the last shutdown was in HDR10 mode, then the next time the device is powered on, it should also remain in HDR10 mode. Let the user make the choice themselves. Because the manufacturer of his display device has not yet resolved the issues that arise when Dolby Vision is enabled on the PC, For example, the color-changing issue of the LG C2 TV。

Windows 11 24H2 Official Version 26100.4349 (KB5060842) = DV is opened. Oh，yeah(^-^) Thank the Microsoft graphics engineers for their efforts.

It is speculated that this Windows system update will introduce a Dolby Vision mode switch in the HDR settings, and this requires the display to have the Dolby Vision gaming certification. It is suggested to inquire about the Xbox engineers of the Xbox Series X and S gaming consoles.

Originally supported Dolby Vision on PC: All computer monitors with the "Dolby Vision" logo on the shopping page. LG OLED televisions from 2024 and beyond：

LG c4 g4 c5 g5 OLED TV

I already know that you can obtain Dolby Vision PC through Windows Update (please let me know if you succeed):

LG b3 c3 G3

LG C2 G2 TV color change （ If you are using the official version and want to fix the color change issue:

1，The graphics card outputs 12-bit ycbcr422.

2，If you don't have the 422 format. Please set it to: RGB, within a limited range. This will disable the transmission of Dolby Vision signals.

3，Uninstall and update in Windows settings. Windows update. update history. Scroll to the bottom. Uninstall update. Uninstall 26100.4349 （KB5060842）26100.4202 （ KB5058499）

The CX indicates Dolby Vision certification, but the TV will not enter the Dolby Vision mode.

 TCL Q10L 2025 TV, the screen logo shows Dolby Vision upon startup, and the TV picture adjustment mode is displayed as Dolby Vision Game. Everything is normal. TCL Q10G, Q10K: In the screen settings, Dolby Vision certification can be displayed, but the TV is still in HDR10 mode.

Xiaomi TV. s pro 2024, displaying the Dolby logo, but the TV is still in HDR mode. REDMI G Pro 27U display: (selecting the TV chip to enable Dolby Vision certification at a low price) Font with color border。

Sony X95K normal。Sony A95L TV turned green and purple after updating to the latest firmware, but it returned to normal after setting the graphics card to 12bit YCBCR 422.

Strange: Why can those people set the output format of their graphics card to YCbcr422? My graphics card can only output ycbcr 444 and 420, and there is no 422?

notice： When other TV manufacturers have not considered enabling Dolby Vision PC on the Windows desktop. There may be compatibility issues. It's not a problem with the Windows system itself.

LG C2 users should contact LG to request for a new firmware update.

26100.4202 = DV OFF (Release Preview channel。

Some people say it is usable, while others say it is not. The Dolby Vision mode switch has disappeared on my computer.)

26200.5603 = DV ON ( Dev channel) Because DEV is not easy to return. I will no longer conduct the test.

The HDR dolby vision mode switch in 26200.5581 was an epic genius update. Why did it disappear at 26200.5600

I had to uninstall 26200.5600. Finally, my TV could light up the Dolby Vision logo on the win desktop. I am willing to stay at 26200.5581 forever.

This is the feature I have been longing for on Windows. I loudly appeal to continue the attempt of this feature.

Nowadays, only a few monitors priced over $1,000 and LG oled TVS have specific switches that can enable Dolby Vision on the Windows desktop.

now，Turn on HDR dolby vision mode switch in 26200.5581. It seems that it can be enabled on all TVS with Dolby Vision certification! Yes, it's all the television. (Except Samsung)

This is a genius functional update. Don't bury this function. This is an epic advancement of the Windows HDR function.
