Hi, i need help...

I have an Alienware 17r3 notebook with Nvidia gtx 970m. When connected to a TV LG OLED 55EF9500 by HDMI and select YCbCr444 4k/60hz, YCbCr422 4k/60hz or RGB 4k/60hz mode on the Nvidia control panel, it looks good but after a while, it loses the connection for a second and back, and is repeated every few minutes.
If I select YCbCr420 mode this does not happen.
TV connection is HDMI 2.0a and HDMI cable (supposedly) is 2.0. Anyone know why this happens? is a cable HDMI problem?
supposedly nvidia gtx 970m and LG 55EF9500 support [email protected] RGB/YCbCr444...

thks!

Yes, you will probably need to try a better HDMI cable.

My E43-D2 shows 444 in the nVidia display applet..........650Ti card @ 1080px60.... It also shows higher resolution choices; but, 1080p provides the best text readability for me. I have a GTX 950 card coming today, so I can test if the text will improve with a true 4K card and higher resolution. I am not a gamer; but have multiple apps open at the same time for genealogy.... I changed from a 3 monitor setup.....

With my Vizio, I liked RBG much better.. As I am not a gamer on this PC......... Text was superior with RBG and creating a custom resolution: 3160 x 2132 @60 - Limited..

It's dynamic, in that, you can leave open a windowed version of your favorite app and try your choices and see almost instantly.

Can't speak to gaming..

Also, note, many say the Vizio's are NOT properly supporting 444. Which may be why I like RBG....... Which, I understand is the gaming default mode?

I've been trying to get up to speed on this thread but I could use a little help.

I am hoping to use a Sony 55inch 850D as a wall mounted monitor for doing AutoCAD. We just purchased new DELL computers and I need a new video card as the ones we had installed do not support HDMI 2.0 as my partner planned on me using two 40" desk mounted monitors. So with that said it appears that the GeForce GTX 970 is the card to buy?

Please let me know if this would be the correct card or is there something else I should be looking at.

Thanks

Dear Forum Veterans,

We plan to buy your models in US and India and have a few questions:

- How many of the HDMI ports are HDMI 2.0 and support 4k @ 60hz?

- Can you please check & specify whether screens support Croma 4:4:4 sub sampling -

- Are the models in US and India the same? If not, what are the technical differences?

We are planning to buy in both places via Amazon Prime.

Please clarify. Thanks

4K UHD TV 4:4:4 60 Hz

If I buy a 4K UHD(3840×2160) 4:4:4 60Hz capable TV and want to use it as a monitor. And for some reason I want to reduce the resolution to say 1920x1080 60Hz. Will it still support 4:4:4? I only remember that for monitors 4:4:4 is a must or the text looks washed out. So want to make sure 4:4:4 still holds for lower resolution. Thanks in advance.

I can’t figure why a display would be 4:4:4 at 4k60 but not 1080. Should work fine.
