Just got a new Samsung SyncMaster P2370HD TV/MONITOR and wanted to plug it into my PC:

PC spec is:

WINDOWS 10 64BIT
CPU: AMD Sempron 145 (SOCKET AM3)
GPU: Nvidia Geforce GTX 260 (x16 EXPRESS 2.0)
Motherboard: * MSA78L M/USB3, (x16 EXPRESS 2.0)
RAM: * 8GB DDR3 1333MHZ RAM *TRI-CHANNEL* 4x2GB KINGSTON
DVD DISC: * 22x SATA DVDBRÆNDER +/- OG DVD-RAM
PSU: * 550W "GAMING" STRØMFORSYNING, SILENT, 17DB
Hard Disc: * 1000GB SAMSUNG HARDDISK, 7200RPM, 32MB CACHE (1TERABYTE)


After conecting and powering up I'm using a HDMI to HDMI cable. My videocard is a Geforce GTX 260 Gainward, with DVI-I, HDMI, 15-pin connector D-Sub, adapter HDMI-> DVI included .

The picture is very distorted and the colors are flattened a lot. The text itself is only just about readable. Around all the text, is some sort of white marking. No matter what resolution I set it at, it remains and so do the bad quality.

The TV resolution is set to 1920X1080 running at 60Hz.
I have tried running at different resolution and refresh rates but still the same quality.
 
do you have another HDMI cable that you can try? could be an issue with the cable for some odd reason. otherwise there might be an issue with the HDMI port on the monitor.
 
I don't think there is such a thing as a "poor quality" HDMI cable, unless it's so cheaply made that it falls apart when you connect it. I think if there's a problem with the cable or the port you'll see the picture drop out completely (I've had that problem before).

Maybe the TV is running in a different picture mode for HDMI compared to DVI - I know when I've connected my laptop to various TVs it doesn't look as sharp as a monitor when looking at small text. But from what you say it sounds like your problem is much worse than that.
 
Thanks for the reply's guys, I have just tried several hdmi cables, so pretty sure it's not the cable. Probably end up keeping the DVI to DVI as it is the same resolution and refresh rate, so not quit sure what would be the pro's with HDMI to HDMI tbh.
Will trey what efish suggested though.
 
I think unless you need to have sound from the HDMI, then you will be fine with DVI. The video signal through DVI should be exactly the same, including support for HDCP.
 
Some monitors apply some extra processing for HDMI inputs that isn't applied to DVI inputs. It should be configurable though, especially on a modern monitor.
 
Good point, sometimes I find my Nvidia drivers have changed my 4K RGB TV settings back to 'Limited' instead of 'full' - Usually happens when Windows 10 tech preview does a full update.

Surprised nobody has mentioned this yet, perhaps you should've posted in the monitor section. You need to correct the colour signal to Full Range RGB as detailed in this article - https://pcmonitors.info/articles/correcting-hdmi-colour-on-nvidia-and-amd-gpus/. Nowadays it's just a simple matter of selecting the correct option from a drop-down in the GPU driver.

Yep seems a pretty clear case, thought everyone would have run into this enough times for it to be the first suggestion!

Information overload. Thought the old fix may be better tried first as older drivers don't have the feature.

Did not want to add more in case it got confusing.

Yes, it's definitely worth ensuring the monitor is handling the signal as a PC rather than AV signal of some sort. The older drivers still allow you to set a custom resolution or you can use a simple utility to fix things up. The colour signal is the more likely culprit here unless the OP is specifically observing a black border around the image that isn't there under DVI - DVI.

Although 'Overscan' has only been an issue with AMD GPUs for a very long time over HDMI, not Nvidia ones. :) The older drivers still allow you to set a custom resolution or you can use a simple utility to fix things up.

People use the the term overscan in day to day use in a generic way. Its a useful search term to find working solutions that many nvidia owners 'feel' they have it would seem;).
