How do i run the deepstream sample: streaming stopped, reason not-negotiated (-4)

I just finished installing DeepStream.
When i run this order:

# deepstream-app -c source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

The system prompts as follows:

**PERF: FPS 0 (Avg)	FPS 1 (Avg)	FPS 2 (Avg)	FPS 3 (Avg)	
**PERF: 96.01 (96.01)	96.01 (96.01)	96.01 (96.01)	96.01 (96.01)

HI
Which GPU are you using? this config supposed you not modified it render output on screen, if you are using Tesla platform, you can follow https://elinux.org/Deepstream/FAQ 5A to setup virtual display
or you can choose use sink type 1 Fakesink or 3 File
