Solved One Monitor - Two DVI/HMDI Connections?

January 25, 2017 at 17:59:25
Specs: Windows 64, 6 GB
I have a new LG 29" monitor. I hooked it to my computer (HP Envy 700-210) via a DVI/HDMI cable. However, my graphics card will not display over 1920x1080 while the monitor's recommended setting is 2560x1080. This means that using the monitor wide-screen stretches the images and blurrs the text. Setting it to normal gives me 4" black spaces on each side. The Best Buy guy suggested connecting the monitor to the computer with a second DVI/HMDI cable so that I could actually use the slit screen feature and clear up the blurr. Before I get another cable, I'd like to know what the 'experts' think.

"I will not be able to take advantage of the 2560x1440 display?"

From what I could find, the max resolution supported by the Radeon HD 8670D graphics is 2560x1600, so you should be able to configure it for 2560x1440 with the latest driver.

EDIT: I think the problem is you're using DVI. If your system doesn't support HDMI or DisplayPort, you will need to install a graphics card that does. However, looking at the specs, the DVI port appears to be dual link (DVI-D) so it's possible all you will need is the proper adapter? But from what I've read, a passive adapter won't do it, it would have to be electronic converter. A new graphics card will be the better route to take.

What is Windows 64? Is that 7, 8 or 10? Do you have an actual graphics card or are you using the integrated graphics? Most likely you just need to update your graphics drivers. But can't help you with that without knowing the graphics or the OS.

Integrated graphics.
I would recommend getting a graphics card. Please specify your general uses (especially if they include gaming, Photoshop, Autocad 3D, Video editing, watching HD or 3D videos, etc) and possible budget so we can guide you.

You have to be a little bit crazy to keep you from going insane.

The guy at Best Buy is incorrect. Yes, theoretically you could split the signal between two outputs however the monitor will only accept 1 input at a time.

If riider's suggestion of updating the drivers doesn't work, then go with Finger's suggestion and get a video card.

To: riider
I am using Windows 10 Home, 64-bit with 8 MG of Ram. My Graphics card is an integrated AMD Radeon HD 8670D. I installed the driver dated 2/26/2016, version 15.301.1901.0 based on the link you gave me. I downloaded the “Radeon Software Crimson Edition Beta.” I then followed the second link to set the scaling mode. The content fills the screen. And the blurry edges of the text seem sharper.

Am I correct that unless I purchase a new graphics card, I will not be able to take advantage of the 2560x1440 display? I currently do not have another device connected to the second HMDI port on the monitor.

The theory behind two DVI/HMDI cables was that it would possibly draw strength from each input to power the display to the maximum. Do you think it’s worth a try?

Thank you for your assistance!

Hi SweenCat,

That makes no sense at all, the display doesn't draw power from the HDMI cable or input (actually I think you mean output). And it still wouldn't matter as it will only use one input at a time so it wouldn't make any difference how many connections went to the monitor.

Stick with riider & Traveler's suggestions, they are valid. The guy at Best Buy knows not what he is talking about.
