In regards to your monitor, future upgrades and such.......
You have an UHDTV or monitor but does it have the installed HDMI 2.0 hardware to accommodate 4K data/bandwidth transfer?
If you're looking down the road at 4K video editing/viewing, your monitor or TV is going to need HDMI 2.0 ports or DisplayPorts both of which are found on 4K video cards.
Anything less than a HDMI 2.0 or DisplayPorts on the monitor/TV won't give you the data transfer to have the 4K experience even thou you may have a 4K video card in your computer. The HDMI 2.0/DisplayPorts provide the 18Gpbs needed for the deep colors and refresh rate of the video. More color = more bits = higher data rate = required more bandwidth.
If you have the earlier HDMI 1.4 ports on your monitor/TV your transfer rate/bandwidth is 10.2Gpbs.
Without the ability to transfer more data, your on screen visuals will basically be the same as it is now without a 4K video card. Simply put, your applications have to match; monitor/TV to the video card.
As for the refresh rate, your probably experiencing 30fps at 60hz if your method of transfer is HDMI 1.4. I believe this will stay the same if your applications don't match otherwise you can get the 60fps or higher but how much I don't know.
This is my understanding. I may be be thinking wrong at which point I would love to be corrected.
Niels, if you recall from my
4K Video and Computer Requirements thread I tried to sort out my needs for viewing and processing 4K video from my Pani FZ1000.
I left that thread, got quotes on machines and monitors to satisfy that 4k quest; all were around the 3500 dollar range. That's for 4K video/gpu card, SSD and HDD drive, optical drive, OS W10, 750W power supply, 16G RAM, lots of USB ports, and a 4K monitor. An over kill for my limited desire to mess with 4K Pani video.
The take away from that thread, may be better suited to your needs, is what
Scotview and
etudiant suggested to me. Click on their names it will get you to their post.
I still want all the 4K goodies but I'm going after it in a different way. I'm a desk top guy so I'm scrounging all the For Sales from ebay, graigslist, and local pawnshops for gaming computers. There's lots out there, from kids wanting to upgrade to kids needing money for college and other stuff. I will adventually find one to my needs for a couple hundred bucks; upgrade the GPU, power supply and I should get in under 1000. After that I'll shop for a monitor.
Niels, I wish you luck my friend......just making the choice is work, I know..!!
