Doubble adapter setup (HDMI 1.4a > Display port > DVI dual link)

[Kristoffer_10]

I recently bought a acer GN276HL(144hz) monitor to use with my laptop (Acer aspire VN7-591g)

My laptop has a 1.4a HDMI output, and the monitor a VGA port, HDMI port (1.2 as far as i can tel.) and DVI dual link port.

I realize i wont be able to achieve greater than 120 hz at 1980*1080 but thats fine, the problem is right now im limited by the monitors inferior HDMI port which bottlenecks me at 60 hz.


As there are no active HDMI - DVI dual link adapters on the market as far as i can tell i was hoping i could first use a HDMI > Display port and then one of the numerous active Display port > DVI dual link adapters.


Does anyone have any experience with this, or know if it is even possible in the first place (regarding compatibility etc.)

thank you in advance

(sorry for the poor english, its my second language)

why not just plug in HDMI from laptop to monitor ? I mean HDMI and DVI have same resolutions easier to find hdmi> display port but since HDMI is limited anyways you wont get a "better" video output from HDMI > Display port... doesn't work that way

Hey the paladin - i am a little confused, could you elaborate?

Surely my bottleneck right now is the HDMI 1.3 input on the screens end? - the HDMI 1.4a can output the needed pixel clock rate, the HDMI 1.3 on the screens end just cant recieve it - while a DVI dual link can.

thanks

your laptop cannot convert HDMI or DVI converter to display port to "increase quality" of signal, it does not work that way
i.e.: take 1080p @ 60hz and push it out to @144hz... not unless you have serious hardware.

sorry but you have what you have, and that is limited by the video output of the laptop

The maximum pixel clock rate for HDMI 1.0 was 165 MHz, which was sufficient to allow 1080p and WUXGA (1920×1200) at 60 Hz. HDMI 1.3 increased that to 340 MHz, which allows for higher resolution (such as WQXGA, 2560×1600) across a single digital link, HDMI 1.3 can achieve 120hz @ 1080p and HDMI 2.0 can do 4K @ 60hz

Best is to just go with DisplayPort whenever possible, it can do 240hz @ 1080p

When it comes to brands the only thing that matters is whether it's HDMI 1.0, HDMI 1.1, HDMI 1.2, etc.

an HDMI 1.3 cable that costs $20 is going to be just as good as an HDMI 1.3 cable that costs $80, even if the fancy one has gold contacts, the reason is that HDMI cables send data in packets, so either the signal gets there, or it doesn't.

Just use any 1.3 or newer HDMI cable.

Though if it doesn't have 1.3 or higher, than your only option is to use a straight dual-link cable.

Return it and get a monitor with hdmi 2.0.

1.4 was common for a long time, so it's surprising it's only 1.2.

Hey, i have allready taken the monitor in use for a week or so and the return policy is expired.

I was quite confident the cable was only 1.2 or lower, sadly i didnt read the manual carefulyl enough to read the max bandwith of the screen (which i must correct myself on, it has to bed 1.2 or lower)

I find ti super frustrating they even sell a 144 hz with a outdated HDMI standard that is incompatible for the refresh rate(without clearly disclaiming it), but nevermind that.

Si basically, there is no way to use

First HDMI to DP converter
Then active DP to Dual link DVI converter?

Thank you for your response¨

Well, it's more you should have done your research first. And not tried to do it with a laptop. A laptop with only a 960m, is gonna have trouble reaching 144hz in many games.

I mean the only way to find the information is through the manual that ships with the product or to download this manual form a thrid party online.


either way, i only play CS:GO and am reaching a reasonable FPS level for it to make sense.

But back to my question - still remains unanswered.

Wether it is possible to daisy chain
HDMI 1.4a to DP

Then get an adapter from DP to Dual link DVI


Thank

Maybe.
It's not cheap, in fact its prohibitively expensive.

The cheap ones you find are single link only.

yeah i know.

thanks for your time good sir, and have a lovely weekend.
