Hi,
I've been using an old Samsung SyncMaster 225MD to hook up to my PC, and until recently, I've been using VGA which worked perfectly. A couple days ago I switched to HDMI and the screen now looks bleached, like the colors are too deep, and the text is blurry and difficult to read. I've been looking everywhere and I tried messing with both the monitor and CCC options to no luck. I thought renaming the HDMI input to PC would work, as it did for other people, but nothing changed. I'm using a Radeon HD 7770 card.

Thanks

Hmm, that is interesting...Well if VGA works perfectly for you in 1080p, why even switch to HMDI?

I wish I could help you, but I'm rather baffled that HDMI looks bad compared to VGA...I'm racking my brain thinking of reasons why but I can't come up with anything. If your TV and GPU both support 1080p HDMI, there isn't a reason that it should look like that...

Well, I have the same problem with Samsung HDTV (2 different models) and after reading a lot of useless ideas I have found one interesting explanation. It says, that the audio on HDMI causes the problem as the TV thinks it is an video signal and applies filters to it. It says disabling the audio being sent through HDMI solved the problem. That explains also, why any connection (DVI, VGA) without audio works well and also why images and video works fine over HDMI, but not the text.

But the monitor/TV has built in speakers, so it supports audio. If it has probably decoding the Audio, then it might just be a problem with the monitor itself.

Well, just to support that explanation, I have connected 2 computers via HDMI into one SAMSUNG TV (HDMI port 1 and 2). The older computer has only DVI port, so I use DVI to HDMI cable, which differs from HDMI only by not transmitting audio. The new notebook has regular HDMI port. Older computer works fine and TV recognizes, that this is a PC connected (writes "PC" next to port name). The text from notebook through HDMI is blurred and TV does not write "PC" next to the port name. The same when I switched ports. As my notebook does not have DVI, I connected it through VGA cable and everything works just fine. Seems to me the explanation with the audio signal inside HDMI causing some TV sets thinking it is a video player and not a PC connection is closest to be correct and the only one really explaining these problems.

So you're saying that your laptop (notebook) connects to your TV or monitor via HDMI and looks blurry? Are you ABSOLUTELY 100% positive that:
A) You have it set to only display on the monitor. NOT "Duplicate screen"
B) It is set to the max resolution of the connected screen?

A) Yes, B) Yes
But I'm only talking about the TV, not the monitor, monitors expect the PC input and they are not trying to enhance the quality of the image (video). This computer works fine with an HD monitor, but not the TV. In the meantime I've found another solution at least for nvidia graphic adapter, there is a setting in section Display->Adjust desktop color settings part Apply the following enhancements called "Content type reported to the display" which is by default set to "Auto". I have changed it to "Desktop" and that solved the problem, TV now recognizes that this is a PC input and everything works fine now. Funny, that this took me over a year to find that solution.

what's funnier is that people who didn't know what the problem actually was were trying to help you. a simple overscan setting on the TV would have likely fixed this within minutes. this has nothing to do with audio over HDMI, it has to do with the HDMI connection to a TV and the communication between PC and TV that says "hey, that's a TV, we need to apply these special settings without telling you about them"

there's hundreds of threads on this "I connected to my TV using HDMI and it looks weird" step 1 is always overscan. step 2 is TV's own sharpening features. step 3 is the TV having a zoom function enabled.

I was trying to help because nobody else did. Any help is better than no help.
Furthermore, it's often a simple problem of resolution or them having duplicate display on. When you use a lower resolution, the screen looks blurry because there are less pixels. It's not like it's stupid to ask about resolution. I've seen tons of threads about blurry screen complaints, and the resolution is often the culprit. If it wasn't that, then I was curious because I've never had this problem and I've connected my laptops and PCs to TVs plenty of times and never had this result, everything always appeared as it should.

You don't have to be disrespectful about it. This is a place of learning for people of all levels. Not everyone is going to be able to help everyone with every problem. But that doesn't mean someone can't try to help.
