144hz Refresh rates and DVI Cables

[WastedBenji]

How many hz could a non dual link DVI cable carry on a 1280x1024 resolution

it can handle high refresh rate, i use dvi (dual) on my 120hz

I use dial link with a 144hz screen without issues(1920 x 1080).

Since 1280 x 1024 uses less bandwidth it is easy to get over 200.

I do not think I have seen a 1280 x 1024 that would be able to handle this kind of signal.

Even HDMI can do this as long as both devices support much higher clock rates. The base HDMI clock rate was based on single link DVI, but they have moved up to support things like 3d and 4k(UltraHD).

Hello... There are cable/connector ratings, typically raw cable will have the information printed continually on the jacket. Length of the run can a difference too... Not all cables are made of the same quality or standards.

I am getting a 1080p 144hz monitor, but I play csgo on a 1280x1024 res so I was just wondering whether I could get the monitor giving me all the 144hz using a single link dvi cable until I get enough to buy a dual link dvi.

On paper single link may be good for about 100hz(based on the bandwidth of 1920 x 1200) at that resolution. This does not mean that some monitors will not take more.

For instance I can get 85 over HDMI. That kind of bandwidth could make maybe 120 to 130hz possible, but you are hoping the monitor can even take the extra pixel clock rates.

A monitor will report to the OS what it can do. For instance, my BenQ screen reports the following(single link because it is on HDMI with a DVI -> HDMI cable).

120hz @ the following
800 x 600
1024 x 768
1152 x 864
1280 x 720
1280 x 768
1280 x 800
1360 x 768
1366 x 768
1440 x 900

@ 75
1280 x 960
1280 x 1024

I would also guess 1920 x 1080 @ 75 should be supported, but HDMI wants to use TV refresh rates.

The bandwidth needed for 1280 x 1024 @ 120 should be possible. I just added the custom resolution and it works fine.

Remember all monitors will have a different tolerance.

I could get a single link cable, but my guess is it would be the same or very close(basic HDMI and DVI talk at the same speed, it is only newer revisions of HDMI that use high clock rates to overcome the single link limit.).
