Cheers.

Ok, yes please, let me know whether this worked for you or not. If you got it working, then it should be the same for my laptop. If it didn't work for you, then I don't think it would work for mine neither.

So please, keep me updated! Thans!

It will not work because HDMI have a max resolution up to 1920*1200.

But this resolution will butcher that card for any games imo.
Edit: Also Welcome to OCN!

You have the beta of CS:GO ?? You lucky bastard tongue.gif

I really want to play that game.

Can you please tell what frames per second you get on native resolution and with which hardware?
Thanks man!

HDMI 1.3 and 1.4 support 2560x1600, and even bigger resolutions:

http://en.wikipedia.org/wiki/HDMI#Version_1.3

Now, I think I just might have answered myself. I'll have to check whether the HDMI port I have is v1.3 or v1.4.

Now, if it is, how likely you guys think would it be that I would be able to have this resolution with an HDMI-DVI adapter?

Type A
Nineteen pins, with bandwidth to support all SDTV, EDTV and HDTV modes.[4] The plug (male) connector outside dimensions are 13.9 mm × 4.45 mm and the receptacle (female) connector inside dimensions are 14 mm × 4.55 mm.[54] Type A is electrically compatible with single-link DVI-D.[55]
Type B
This connector (21.2 mm × 4.45 mm) has 29 pins and can carry double the video bandwidth of type A, for use with very high-resolution future displays such as WQUXGA (3,840×2,400).[55][56] Type B is electrically compatible with dual-link DVI-D, but has not yet been used in any products.[55][57]

Electricaly not compatible means it needs an active adapter. The same way DP is not electricaly compatible with dual-link DVI and thus needs an active adapter like this :amazon

The problem here is that I don't think active HDMI type A to dvi adapter exists

edit : and type A and type B are not physically compatible (doh.gif), I think that's why type B are not really used.

Do all the shimians suffer from the buzzing? I have heard a few people who complained of this which kinda freaked me out. Has anyone gotten one that didn't buzz?

So... what does that mean??? You think it won't be possible?

I would say that if the HDMI standard supports 2560x1440 and bigger, there should be a pretty standard way of converting between HDMI and DVI... that's what seems most logic to me.

My graphics card does support this resolution. The bottleneck would be the HDMI port. But, if I have a HDMI 1.4 port, I understand that such a bottleneck wouldn't exist. This means that I will have to find an adaptor that converts from HDMI to dual-link DVI.

The thing is, I've been googling a bit, and I can't seem to find wether my Acer Aspire 7750G has HDMI 1.4 or not.

You guys know some way to check my HDMI port version?

You can check on the laptop's manual or in the specification of the ATI video card on ATI website

The HDMI port that supports 1440p requires a physically different port. HDMI 1.4 technically supports it, but without the right connector, it simply won't work.

Think of it this way... you need a DL-HDMI port, which is the Type B connector CharlesK referred to. If you can plug in a regular HDMI cable into your HDMI port, you do not have a DL-HDMI port... therefore, even if your video card supports HDMI 1.4, it doesn't have the physical connection required to output a DL-HDMI signal.

Hi, so will it even work with 1920*1080 from HDMI to DVI?

Thanks
