try the cables i used a 24hz 4k cable at first by accident and got a black flash on my screen every second then when i used the provided cable its been running fine for over a yearYeah so I'm still getting issues
I wondering a couple of things, windows 7 doesn't see my Sony TV as the monitor it sees the av reciever which makes sense as it's plugged into that first and in the windows resolutions bit it still says 1920 X 1080 is (Recommended) but why? Other resolutions about this are available so why does this one have recommended in brackets next to it.
The problem isn't quite the same as before, now when I select 4K res in windows the amp reports a steady signal but then the TV reports no signal where as before the amp was flickered it's HDMI status light suggesting the source signal was cutting in and out.
I'm starting to think it could be my cables, it's the only thing left to check before accepting it's not going to work with my setup.
I have IBRA High Speed Pro Gold cables, claim to do everything under the sun but perhaps don't, perhaps aren't that good quality, good enough to run a PC signal.
"- Smooth transmission of extreme HD resolutions up to 4096 x 2160 @24hz (Naturally lower resolutions are also supported)"
This is quoted in their description, why only 24hz?
Sorry for the long post but I'm at my wits end trying to get my media setup to start playing 4K, it's doing my head in now ha!
Make sure that your PC is plugged into a HDMI socket on the amp that supports 4k and HDMI 2. Some amps have inputs that don't support the necessary standards.
Good to know that worked! Amazon Basic cables are just fine. I use them myself with no issues.
The GT 1030 will give you 60Hz, hardware HEVC decode, and HDR (if your TV supports it). So still worth considering even if the on-board worked.
Are your cables up to spec both in and out of your amp?
Glad to hear you got it sorted and that my advice served you well. I also found that audio from the Nvidia card was much more reliable than using the onboard. With the onboard I would get the occasional pop, crackle or momentary drop out. The GT 1030 is a great little card for HTPC duties.
DXVA2 implementations come in two variants: native and copy-back.
With native implementation, the decoded video stays in GPU memory until it has been displayed. The video decoder must be connected to the video renderer with no intermediary processing filter. The video renderer must also support DXVA, which gives less freedom in the choice of renderers.
With copy-back implementation, the decoded video is copied from GPU memory back to the CPU's memory. This implementation doesn't have the limitations mentioned above and acts similar to a normal software decoder, however video stuttering will occur if the GPU is not fast enough to copy its memory back to the CPU's memory.
Native mode is advantageous unless there is a need for customized processing, as the additional copy-back operations will increase GPU memory load.
GPUs that should be fast enough are:
- AMD: Radeon HD 6xxx and newer
- Nvidia: Nvidia GeForce 500 Series and newer
- Intel: Intel HD Graphics 2000 and newer
