Still not sure what to make of this because I know I've been using this output color format before without getting a signal during the boot process so the only things I can think of that could have changed are:Ģ. Amazed by this fact I did another restart and pressed 'DEL' to enter setup and what do you know.UEFI showed up on my 4K TV Looking at the 'Output color format' under the 'Change Resolution' section in Nvidia Control Panel I noticed it was set to 'RGB' rather than 'YCbCr444' and after changing this next time I restarted my computer I noticed how I didn't get the 'No signal detected' message on my TV. Happy to let you know I found a fix for this issue by chance. In the end it's always us (the people spending lots of money) that will decide in what direction things will go. Oh well.let's see what the future brings. Looking at how much you'll have to pay to get a monitor in the same size as a TV of course they don't like to loose that source of income. Maybe the main reason that didn't already happen is lots of the TV manufacturers not only manufacturs TVs but also monitors and now when today's TVs are as good as they are resulting in lots of people start using them as monitors if they would also fix this kind of issue they wouldn't sell that many monitors anymore. I honestly don't think it would be very hard to address this issue if the manufacturers sat down together and looked into the issue and what's causing it. Regardless how you choose to look at it it's in everyone's interest I think that the manufacturers work together to solve these kind of issues since that would boost the business both for the TV market when more people start buying TVs but also for graphic cards manufacturers since more people would be going for a card that can handle 4K. 'Ok, so you think the TV is the problem but what happens if you go into Windows? I bet your TV will work just fine then so obviously the graphics card doesn't send the correct signal to the TV without help from the Nvidia drivers.' You could just as easily put it like this Then if that points in the direction of the TV or the graphics card all depends on how you look at it. I believe I already mentioned this in my initial post.
If I connect the cable to my 1080p monitor I do get a picture outside Windows. Should also add that my motherboard is an MSI Z170A Gaming M7, my graphics card an MSI GTX 980Ti Gaming 6G and my TV is a Samsung UE48JU6675.
Wouldn't it somehow be possible to have UEFI send out the same signal the Nvidia drivers send?Ĭonsidering more and more people are running 4K screens I think this problem will only become bigger in a near future. I know this is not a problem specific to MSI because I had the same issue with my previous system and I also read lots of other people are having the same problem but I still wanted to ask in here, isn't there anything that could be done to fix this problem? To me it looks like the Nvidia drivers need to be loaded before the graphics card sends a signal that is recognized by a 4K TV.
And should I need to enter UEFI for whatever reason I first need to move the HDMI cable to a second 1080 monitor I have next to my main PC.
Normally this isn't a big issue considering you spend most of your time in Windows but it's still very annoying not being able to follow on the screen what is happening during boot and before Windows has loaded. Once Windows has finished loading the TV comes alive and all is good.
As the topic says, I have a problem where I don't get a picture on my 4K TV connected to my 980 Ti Gaming graphics card during boot.
