whenever i stream movies that says BRrip or 1080p its often very lousy quality.. was curious if its because of my hardware that im running on my pc to hdmi to my 1080p 55inch. i added a SS of the specs of my rig its pretty old but runs decent. i have a 70inch 4k vizio being delivered tomorrow so im trying to figure out everything i need to know to receive that 4k quality. debating if i should spend like 800$ and get a nice home theater/gaming rig for the new tv.

 

also seems if i download the movies say in 1080p the picture is definitely better but still not like if i were to buy a 1080p dvd and pop it in my ps4.. any info would be greatly appreciated

Drivers are updated, hdmi cable is good quality and 5ft long... If I upgraded my gpu wouldn't that help the quality of the picture on the 4k TV? And also upgrading the cpu or not so much

These are NVIDIA drivers.  You need to uninstall the old drivers first, then install the new driver.  Did you do this?

I think it's more likely the quality of the source material. The more compression used the worse the quality.  How does it work with an original BluRay as opposed to a streamed "rip".  High quality 1080p Blu Ray video may be around 20 mbps (approx 8.4 gigabytes per hour of video).  If you compress it to 10-20% of it's original size (quite possible) it's going to lose detail and quality.

 

If your computer cannot cope with playing HD video (and it should cope OK), that will normally show up as regular skipping on the video, rather than a reduction in quality.

That makes alot of sense.. If someone were to download a 9 gig 1080p movie and play it on there TV there shouldn't be any graphical issues ur saying. true 1080p quality.

I'd say it's worth investigating yes.  From further reading I've seen BluRay can have bit rates of 40 mbps+ although often a large percentage of that is taken up by lossless audio (e.g DTS-HD Master audio).  But clearly there's going to be a quality difference between that and something which has been compressed down to 1 or 2 gigabytes.

 

You might also try different software for viewing video.  Enthusiasts often use things like Media Player Classic HC rather than Windows Media Player, because it has a lot of options for tweaking (like using different video renderers).  I use the K-Lite Codec Pack which comes with MPC-HC and various tweaks..

 

Certainly these are things I would look at before considering changing hardware as that may result in disappointment if video quality is the only reason for upgrading :)

hooked the computer up to my sony soundbar through one of the 3 hmdi out ports and it turned on fine on the 70 inch.. any one know why that could be? the internal amplifier/receiver in the soundbar gave it enough juice to go work or no
