tech questions.hdmi , dvi , 3d ,connections

[tresoldipaolo]

Hi there, thank you to drop in , as i am a newbie with monitor ,i will like to ask some question about monitor,that might be really silly but i will like to be clarified about.

1) What the use of a second hdmi connection , will be a better quality , or as the double dvi connection useful for 3d only. and if is better quality how i connect the 2 hdmi from my graphic card to a single hdmi in the monitor?

2) I have noticed most monitor as 1 dvi connection but often i heard for 3d as a example that a double connection dvi is needed , how you go to do that, there is a converter that take 2 dvi from the gpu to connect to the monitor ? or how?, sorry bit ignorant about.

3) at last is 3d really a thing to have now or after 15 min of gaming or watching you have a head hake , and better wait till the no glasses monitor will be out probably next year.but do take advantage of the 120 hz resolution of the monitors , for gaming.
my current resolution 1680x1050


thank you to all , for answering.
Paolo

1) A second HDMI connection allows you to connect an additional HDMI device to a monitor (eg Xbox 360, PS3, Blu-ray player, sky hd box, PC). If the monitor is 3D capable and the HDMI port is to the HDMI 1.4 spec then it can be used with 3D content via HDMI.

That said, due to the greater bandwidth available with dual-link DVI - this connection is better for 3D content compared to HDMI (v1.4). The HDMI 1.4 spec only allows 3D content at 720p@60Hz (per eye) or 1080p@24Hz (per eye) - in contrast dual link DVI allows full 1080p@60Hz (per eye). Since most of these monitors are 1080p native resolution, and 24Hz isn't really acceptable for gaming then with all else being equal dual link DVI is the better choice for connecting up a 3D monitor to a PC.

However, only PCs (and more specifically PCs with nvidia graphics cards) make use of 3D on 120Hz monitors with dual link DVI connections. Other devices (360, PS3, blu-ray 3D players, AMD's 3D tech) use HDMI 1.4 and require a 3D TV or monitor with this connection - dual link DVI is of no use for these devices and converters are no use.

2) Yes, for using nvidia 3D vision (currently the best tech for 3D PC gaming) you need a 120Hz monitor with a dual link DVI connection, see here.

If a monitor only has a single link DVI connection then it either isn't a 120Hz (3D capable) monitor or it uses HDMI for it's 3D technology. In either case a converter will be of no use for 3D.

3) Personally I would skip 3D tech for the time being (wait for them to nail down the technology) and in the mean time get a lovely IPS panel like the Dell U2311H.

Thank you for clarify a bit more for me , yes it is obvious now that i will not go for 3d gaming till will be good to do so , I am an amd graphic card do 9650) i think the most will be better to get a 120hz only to play at 2d 120 hz , if it is that the case so , i notice the dell does not have a hdmi connection , as the lg LG W2363D 23" TRUE 120Hz 3D Widescreen LCD Monitor - Black , does , using a 2d will be gaining to have a hdmi ? also notice a 50 pound difference is that any good?is probably not a ips panel , but , what you think?
thank you.

Thank you for clarify a bit more for me , yes it is obvious now that i will not go for 3d gaming till will be good to do so , I am an amd graphic card do 9650) i think the most will be better to get a 120hz only to play at 2d 120 hz ,

That is fair enough, fast paced games usually feel smoother when played on a 120Hz monitor which is nice. Also, most of these 120Hz monitors have very low or no input lag which is great to have if you are playing competitive multiplayer FPS games.

if it is that the case so , i notice the dell does not have a hdmi connection , as the lg LG W2363D 23" TRUE 120Hz 3D Widescreen LCD Monitor - Black , does , using a 2d will be gaining to have a hdmi ?

If your main use for the monitor is PC gaming then DVI is just as good as HDMI. The video signal is the same - so the image quality is identical (plus DVI doesn't have the issue with scaling that HDMI often presents). So please don't be put off the dell due to the lack of HDMI.

HDMI is really only required if you plan to plug in a HDMI device (console, blu-ray player, HD Digibox) or run 3D off an AMD graphics card (and the monitor supports 3D via HDMI).

also notice a 50 pound difference is that any good? what you think?
thank you

The Dell is only a 60Hz monitor and ~£60 more expensive but there is a good reason for the price difference. The Dell uses a high quality E-IPS panel (compared to the TN+ panel on the LG) which gives excellent colour accuracy and wide viewing angles (so when you move your head a bit the colours don't shift - which they do on TN). For this reason the U2311H has become a bit of a favourite here - even for playing FPS games. It isn't quite the fastest or most responsive monitor on the market - but it does well enough in these stakes. It is the high quality IPS panel that makes it all worth while and many people are using the U2311H on these forums and play games and they find it does rather well.

Here is an in-depth review of the Dell.

I see , that really interesting , thank you for all your knowledge on the field. I have to say that most of the time i am sitting on the front of my pc , right side of my monitor i have the pc case , left side a wall , so it is really a full frontal view, so no major angle movement . I have also to say that after been working for Dell here in Ireland i probably got a bad attitude toward them , but with this monitor does not seam the case, decision , decision , i will make them up soon, but in the mean time thank you , because you make it really more clear for me .
