Windows 10: Intel UHD Graphics 620 not supporting

I recently bought dell laptop. But when I am enabling intel uhd graphics 620 unable to play videos(specifically youtube) and also unable to wake laptop from sleep. After disabling intel graphics driver in device manager those things are working fine. Any idea what's happening. Model - Dell 5370

intel UHD graphics no HDR

can someone help me solve the problem with the HDR option connected to intel uhd graphics 630 last drivers

my processor intel i7 8700k motherboard Fatal1ty Z370 Professional Gaming i7 nvidia 1080ti

the problem is that the HDR option is not available in windows 10 vers1709 bulid 16299.125 when connected is to intel graphics

if the connection to the nvidia card HDR is available .

as it is connected to nvidia dxdiag shows DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020, that indicates
that this is for HDR10 and the connection is displaying advanced color.

when to intel show DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709,that
indicates this is sRGB and not advanced color.

intel support claims that this is the fault of windows

please help thanks

intel(r) uhd graphics card 620 43 error

So of course windows had to do another update and now I have "intel(r) uhd graphics card 620 43 error" this problem. I was running games like Overwatch and League just fine but since the update I get terrible FPS and my games are unplayable. I have tried
troubleshooting and it says we have no solution for you. How is that possible there is obviously an error and needs to be fixed.

I need a solution please because this "gaming laptop" can't play any games.

Thank you.

 

I received notice "Application firefox.exe has been blocked from accessing graphics hardware"

I don't have any of the graphics cards you list - I have Intel UHD Graphics 620.

What do I do now?
