DL DVI display 3440 x 1440 at 60hz ?

[Harjan]

Hello,

I know that DL-DVI can support up to 1440p at 60Hz, but i was wondering if it could display 3440 x 1440 at 60hz aswell ?
I hope someone can answer that question.

I got a backorder on a LG 34UM95, but might put up the wait and go for the AOC u3477Pqu if the DVI port can display that resolution at 60hz

Edit :
Ohw and it will support 30Hz right ? considering that's only half the bandwith.
As i'm going to connect 2 PC's to that monitor (1 for gaming and one for webbrowsing and such, when i'm gaming on my triple monitor setup), so it wouldn't be that big of a deal to run at 30Hz at one input. Still 60Hz would be prefered though.
But yeah then i might aswell go for the LG as it has 2 HDMI ports, which should (each) be able to handle 3440 x 1440 at 30hz right ?

I think you need to use DP for 3440 x 1440 60hz

I'm basing this on the shady memory that 2,5k at 60hz was near dl dvi limits

[Harjan]

Max. resolution on DVI for 60 Hz ofc is 2560x1600... which is 4096000 pixels

That one you want is 4953600 pixels, you are pushing it a bit... it'd handle it but I'd go DP.

Thanks for the info!

So your saying/thinking it wil run at 60Hz, but wont be optimal?

The problem is that both of the monitors only have 1DP input for some odd reason...

[Harjan]

?

1 dp is enough for that resolution (up to 4K @ 60 Hz...)

I know, but it wont be enough for "2" PC's

And switching the cables everytime is no option.

Maybe if i find a decent DP switch with 2 input's to 1 output. Maybe that will be an option if it doesn't degrade the quality.

You are probably right there. I thought maybe if you would use an el cheapo switch, as it also will be a fairly long cable. And i know back in the days with HDMI, if you had an cheap cable that 10meters (or longer). It could degrade the quality.

Ofc i know DP is far superior, but im (by far) no expert in this area, so that's why i'm asking

But yeah, so it will only add one extra point of failure .

If the other one is just for web browsing then HDMI will handle that resolution at 50Hz.

HDMI 1.4 that is.

If it really will run at 50Hz, then will be fine for the secondairy display

That's if it will. I'm left a bit unsure now.

If HDMI 1.4 runs 4k at 30hz, that makes 3840 * 2160 = 8,294,400 pixels per frame * 30hz refresh rate = 248,832,000 pixel refreshes per second at maximum bandwidth

 

The LG screen is 3440 x 1440 = 4,953,600 pixels per frame

248,832,000 pixel refreshes per second @ 4k / 4,953,600 pixels on the LG = 50.23hz maximum refresh rate

 

According to the bandwidth spec it should be able to handle 50hz then.
