Can't get Samsung UHD TV to work with Intel UHD Graphics 630.

Have UHD Graphics 630 (on Win 10) that worked fine with my old Panasonic HD TV over HDMI cable. Trying to get my Samsung UHD TV to work over same setup but keep getting 'no signal'.  Strangely I see my duplicated screen flicker on randomly for a few seconds at a time on the TV. When I try to detect the second monitor I get "Didn't detect another display" yet under Advanced Display Settings It shows a 'Samsung' Display. See attached image. I'm at a loss.

Sorry about the delay.

 

Samsung UN55MU6290

Latest firmware: T-KTMAKUC-1270.3

 

Here's the Amazon description for the HDMI cable I'm using: Mediabridge ULTRA Series HDMI Cable (35 Feet) - High-Speed Supports 4K, Ethernet, 3D and Audio Return

 

Keep in mind that this exact cable/setup works with my Panasonic Plasma HD TV. I'm only sending HD resolutions (1920x1080) across the cable on the Samsung TV, not UHD.

It is not unexpected that the device may appear to be present yet will still not connect. This is typically the result of having a HDMI cable of insufficient capability/quality. I would try a better cable (you need one that is of type Premium High Speed HDMI Cable).

 

Hope this helps,

Hello AGadg

 

Thank you for the details.

 

I am noticing that you have currently two displays on the system, have you tried testing the SAMSUNG* TV on the with the other video cable that connected to the DELL™ display?

Have you tested using a different video port output on the motherboard (swapping the current set up)?

 

Can you provide me with the Intel® graphics report following these steps:

 

1. Right-click on the Desktop, and click on Graphics Properties.

2. Click Options and Support, and then click Information Center.

3. Click on Save (save it in your desktop).

4. To attach a file, you must click the “Attach” option on the bottom left-hand corner of the response box.

I have the the Dell on the DVI port and the Samsung TV on the HDMI port. Haven't tested the Samsung TV on the DVI port since I don't have a DVI to HDMI adaptor. Graphics report attached.

Hello AGadg

 

Thank you for the system details, after reviewing the graphics report is am noticing that the system did not find the SAMSUNG* display, in this case for testing we recommend connecting the SAMSUNG* TV on the HDMI® port with a different HDMI® cable as N. Scott Pearson has advised previously.

New HDMI cable is in the mail. Will let you know how the test goes once I have it.

Turns out the problem is the distance of the cable itself (49 feet). The distance worked fine for my old TV which was HD but does not work for this UHD TV. I assume this is because of the additional data that is transferred over the cable.

Followup: I had reduced the cable length down to 40 feet and it seemed to work fine at first but started to get the problem again where the TV would drop out to a blank screen and say no signal. I ended up changing the Active Resolution to 60hz and that really did solve the problem. I have been using it fine for hours now.

 

For others that want to try this go to display properties -> advanced display properties select -> select display adapter properties for the display -> List all modes.

 

You might need to do this as administrator. Play around with the different resolution/modes to match your display.
