Perfect Blend 4-4-2

[Shawana Messerli]

Hi
i have a question about Plugable DisplayPort to HDMI Active Adapter. i have connected my amd 390x to my lg tv 55UJ634V with this adapter and a 5 meter hdmi2.0 cable. it works with 4k@60hz 8bit but there is no option in the amd settings to choose chroma sampling. (the option is there when i use the hdmi cable without the adaptor). the tv has the advanced color settings on all hdmi ports. any thoughts on what i could do to enable 4:4:4?

When the Chroma Sub-sampling settings are not available in the Radeon software, the settings are being automatically negotiated by the system, DisplayPort to HDMI adapter, and monitor. This auto negotiation is based on the features requested as well as the quality of the signal. I recommend starting by testing with a shorter cable, no longer than two meters to eliminate problems often seen with longer cables and signal loss preventing 4:4:4 sub-sampling. To expand on this, the DisplayPort has to not only power the DisplayPort to HDMI adapter but also the HDMI signal along the cable, without the additional conversion to HDMI the 5m cable may work fine, however with some power used to convert the signal to HDMI the cable is susceptible to more interference and the resistance along the length of the cable can cause the automatic negotiation to increase compression.

Hey, I really appreciate the fast and comprehensive response! What you said makes perfect sense to me so I will try the 2m hdmi cable. I just thought I should let you know that I wont be able to test it until tomorrow. Until then I have a question, is there a way for me to check which Chroma Sub-sampling settings are being used at any given moment? I mean since the setting is not available in the Radeon software I have no way of knowing which setting is being used. For all I know 4:4:4 might already be in use!?
thanks again for the help, I will give feedback about the shorter cable tomorrow.

The lack of sub-sampling options indicates the Radeon software is correctly identifying the connection as DisplayPort output and is not attempting to compress the data, which is a good thing in this case as it preserves the image quality. To expand on this, HDMI was designed to be used with compressed video sources such as DVD which had already been sub-sampled down to 4:2:2 or 4:2:0 so applying the Chroma Sub-sampling does not reduce the picture quality, however DisplayPort was designed to send pixel perfect data to the monitor, the Radeon software may not allow for Chroma Sub-sampling on the DisplayPort for the optimal picture quality.

The Plugable DisplayPort to HDMI 2.0 Active Adapter supports up to HDMI 2.0 specifications allowing for 8 bits per color channel. HDR would require an adapter that supports HDMI 2.0b specification which added support for HDR10 ( the most common HDR implementation ).

At this point I think you are seeing the expected and optimal output. Chroma Sub-sampling is disabled on the Radeon software and negotiated to 4:4:4 between the television and the graphics adapter. The lack of HDR support is expected based on the specifications of the graphics adapter.

Did you mean I should view the image at its original size (720 from the specified site) or that I should zoom it until it fits the hole screen 100%?? because all the text is easily readable at full zoom but at its small original size the red/blue lines are completely unreadable while most of the rest of the text is still readable. The strange part is that at the original resolution of the image the text is still unreadable even with the hdmi cable without the adapter where amd settings show 4:4:4 (you can see that in the pictures I posted earlier)! Is that normal?

On a side note if I view the same image in its original size on my old 1080p monitor connected with dvi the image is as clear as it can get, even the bottom 2 lines are practically flawless and as easily readable as all the rest of the text.

The image should be viewed at 100%, so it will be quite small on your TV. The text will be very small, but if you can read the lines above the red/blue lines then they should be readable as well. The site I linked to early has some examples of 4:2:2 and 4:2:0 for reference. Please feel free to take an up-close picture of the screen showing the red/blue lines with the HDMI native connection and with our adapter so we can compare the picture quality.

I am attaching pictures that I took with my phone so that you can see what I see. the first two pictures are with the adaptor on and the third is with the HDMI native connection. basically I tried a lot of combinations of setting with and without the adaptor and there is no mode or setting that can make the last two lines readable! The 4th picture is from my old 1080p monitor with dvi connection where the text is perfectly readable. Even if I use 1080p on my tv instead of 4k that text is still unreadable. Any ideas on what else could be causing this on my tv?

I tried to compensate by adjusting brightness and contrast settings but then I end up with two extremes. I can ether have the red line perfectly readable from more than 2 meters but with the blue one unreadable and the hole screen way too dark OR I can make the blue line perfect but with the red one unreadable and the screen way too bright.

That is great, it sounds like the monitor is now working at 4:4:4 ( uncompressed mode )! I am glad that worked, it is just one of those odd settings. I would expect those lines to be VERY hard to read on a 4K television ( the pixels are generally smaller and this makes small text like this hard to read ) as they are blue text on red and red text on blue, the colors will tend to blend to a violet/purple color. The best tests for color quality is to look at photos, for instance searching for color calibration pictures on your preferred search engine should bring up a number of example pictures and you can compare these to real world images ( or connect the 1080P display to compare the color quality ).

So I just tested it with the hdmi cable alone and the results are very similar. I can make only one of the lines visible from a reasonable distance. Only the blue line is clearly visible and the red just sort of blends together. if I also enable hdr with the native HDMI then only the red line is visible and the blue one blends together. to my eyes it looks like a color/contrast problem.

sorry i posted my last answer before I saw yours. its great news that im at 4:4:4: thought, thanks for that! just let me try a couple of more things first and I will get back to you with my final results!

That said I did do extensive experiments with the tv settings you mentioned and with radeon settings and I did manage to improve the image quite a bit! I want to stay in game mode on the tv picture settings. Under game mode most advance settings were grayed out but changing black level to high and gamma to low did help a bit.

The problem is that this changes how the colors look and the red line is now a more pinkish red and the text still looks worse than my 1080p monitor (especially when viewed from a distance). All other images, texts, vids and games actually look normal to me. Its just those last two lines in this test that never look good enough (especially when compared to my 1080p monitor).

There's arguably no position more important in football than central midfield. It's extremely tough to win matches without controlling the middle of the pitch; therefore, it's imperative that your midfielders perform the correct duties to suit your tactic and dominate the opposition.

A common way to do that is with the 'double pivot', a term used to describe two central players who sit at the base of the midfield to offer protection for the defence. Choosing the right roles to use in your double pivot will depend on what you want them to achieve, but there are several ways to use them successfully. On The Break FM explains how to get the most from a double pivot in FM22.

The 4-2-3-1 is one of the most frequently used shapes in modern football and is perfect for making the most of a hard-working double-pivot. This setup allows the more attacking players (the number 10 in particular) to focus on making match-winning contributions with their creativity while worrying less about their defensive responsibility. It also provides security to the full-backs, who can join the attack knowing they have additional cover dropping in behind them.

In the above example, a Ball-Winning Midfielder is partnered with a Central Midfielder, both on Defend duty. The natures of these rules should ensure a good level of pressing from the duo while also maintaining our positioning. In this system, the double-pivot is there to break up opposition attacks before laying the ball off to the more creative teammates. This double-pivot pairing should also work well in a 5-2-3 or a 4-4-2 where the full-backs instinctively look to bomb on and overlap their wingers.

One benefit of using a double pivot is the ability of the players to work in tandem, with one joining up with the attacks while one covers defensively. A great option to perform this task is the Box-to-Box Midfielder; their runs from deep when in possession can break the lines of the opposition while also offering a goalscoring threat. However, they also work hard to ensure that they get back into position quickly to maintain the solidity of the double pivot.

By pairing the Box-to-Box Midfielder with a Deep-Lying Playmaker on Defend duty, we have the combination of a runner and cover that we require. When in possession in the 4-4-2, the Deep-Lying Playmaker will hold their position and play the ball out to the wingers or use the passing angles to find their midfield partner, who in turn will aim to link up with the strikers. Out of possession, the Box-to-Box Midfielder will track back, returning to their position alongside the DLP, while the wingers will also retreat to create two lines of four in the defensive block. Using a runner as part of the midfield pivot works well in most formations, providing they have the engine to get up and down effectively.
