Hello,

I plan to buy the Samsung C49RG90, and would like to know if Shadow support the native resolution 5120x1440@60hz ?

Thanks.

I am running Shadow with a Odyessy G9 (5120 x 1440) and can comfirm it does work, although it wants the default res to be 3840 x 1080@120Hz).

 

You enable 5120 x 1440@60Hz by enabling H.265 in the Shadow menu.

 

I do get some pulsing in the image though.

I get the same “pulsing” on higher resolutions as well. Have you found the cause/resolution?

These estimated calculations might help:

Hey @Chaos_Supreme  @villo1988,

try limiting the FPS to 60 in your shadow launcher-settings and in the game you are playing. Make sure it is set to the correct solution and Hz (60) in your nvidia control panel on shadow.

Thanks @Phobos for the suggestion, although it didn’t make a difference. I think the problem is my iGPU which isn’t powerful enough to decode 4K @ 60Hz. 
 

Hey @Gelgoog - this is a very useful list - how do define “supported hardware”? Does that mean that Intel ≥6000 is capable of decoding 4K @ 60Hz?

@villo1988 

Pushing 4k 60 for most intigrated graphics is possible as native decode of h264 is supported by the intigrated intel or amd gpu. But as their is no buffer in the stream and you will experience dropped frames or as you put it earlier the “pulsing” issue when at higher resolution. You can allways scale down your resolution to alleviate strain on the igpu or when funding permits grab a gpu for your system. If you have a laptop with thunderbolt then your options would be a gpu enclosure with thunderbolt interface. -Gelgoog
