either dl-dvi or dp to dl-dvi active adapter is your only choice. hdmi to dvi adapters don't work. this is a 2560x1440 monitor with high bandwidth requirements. That's why it's dl-dvi on 27q which has no scaler like multi input version.

more indepth conversation about hdmi and this monitor already in the thread. just search the thread using button above/below

Anyway, HDMI to DVI max resolution is 1200p

I guess that answers it, I'm using a 7970, HDMI 1.4A supports up to 4k, is it just a limitation of the cables/adapter?

Just use DVI to DVI ??? headscratch.gif

DVI and HDMI compatibility

HDMI is a newer digital audio/video interface developed and promoted by the consumer electronics industry. DVI and HDMI have the same electrical specifications for their TMDS and VESA/DDC links. However, HDMI and DVI differ in several key ways.
HDMI lacks VGA compatibility. The necessary analog signals are absent from the HDMI connector.
DVI is limited to the RGB color space. HDMI supports RGB, but also supports YCbCr 4:4:4 and YCbCr 4:2:2. These spaces are widely used outside of computer graphics.
HDMI supports the transport of packets, needed for digital audio, in addition to digital video. An HDMI source differentiates between a legacy DVI display and an HDMI-capable display by reading the display's EDID block.

To promote interoperability between DVI and HDMI devices, HDMI source components and displays support DVI signalling. An HDMI display can be driven by a single-link DVI-D source, since HDMI and DVI-D define an overlapping minimum set of supported resolutions and frame buffer formats. In the reverse scenario, a DVI monitor that lacks optional support for HDCP might be unable to display protected content, even though it is otherwise compatible with the HDMI source.

Features specific to HDMI, such as remote-control, audio transport, xvYCC, and deep-color, are not usable in devices that only support DVI signalling. However, many devices can output HDMI over a DVI output (examples: ATI 3000-series and NVIDIA GTX 200-series video cards),[7] and some multimedia displays accept HDMI (including audio) over a DVI input. Exact capabilities vary from product to product.

The whole point of this is to use HDMI so I can set custom resolutions of up to 4K for downsampling which I can't do through DVI since the max resolution is 1600p.
post #4926 of 6483
the point is monitor requires dl-dvi.

Thanks, I got it running...... I have a Samsung also, & this has deeper colors than it. Crossover I would recommend to anyone.... Loving it a lot... thumb.gif

It's a limitation of the DVI spec - a dual link DVI signal is electrically different from an HDMI signal of the same bandwidth. This is a hard limit. HDMI 1.4 cannot be converted into DL-DVI without some fancy converters, which may or may not even exist.

And I doubt your monitor can handle HDMI 1.4A. But that's just my thoughts.

Errr... Get your video card to do it. It does downsampling better than the monitor ever could anyways. I don't know if drivers nowadays support it, but you're essentially talking about a super-sampling anti-aliasing mode. And it doesn't involve any fancy requirements on your cables.

I'm thinking about buying a Samsung or Dell emblem on eBay and putting it over the crossover logo. It's hideous. Thoughts?

»I'm thinking about buying a Samsung or Dell emblem on eBay and putting it over the crossover logo. It's hideous. Thoughts?«

I think this is a properly stupid idea. It's a Crossover, not a Samsung or Dell. Why make a fake of it? Are you a fashion victim or a brand name junkie? Why are you even asking other people's opinion about it? If you want to make that fake, just go ahead without bothering what others think … like men do. wink.gif
