The "total" count is including the blanking intervals, which are pauses in the data stream between transmitting pixel data. These time intervals are typically notated in "pixels" to make computations easier. The actual image resolution is set by the "Active" pixels, in this case it is 1920×1080 which is correct. If you're trying to create custom resolutions, you should set the timing standard to CVT Reduced Blank, not leave it on automatic.

This doesn't bypass the NVIDIA 4-display limit, which is what the OP is trying to overcome.

As 1440p 165 Hz requires more than half of one DP connection, you cannot run more than 1 monitor per port at full 165 Hz.

Based on the manual, the HDMI input on the monitor is limited to 60 Hz at 1080p.

No, motherboards almost always are single-link only. Here are some examples of other ASUS B450 motherboards that do list the spec outright. https://www.asus.com/us/motherboards-components/motherboards/tuf-gaming/tuf-b450m-pro-gaming/techspec/ https://www.asus.com/us/motherboards-components/motherboards/prime/prime-b450-plus/techspec/ Please note that there is no such thing as a physical "single-link" DVI port as your image above indicated. That does not exist, except on some (not all) plugs on the end of cables. All DVI ports look like the "dual-link" examples. Again, please refer to the pinned thread, as there are many common misconceptions regarding DVI and the identification of a device's capabilities. Looking at the physical port basically means nothing. https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?output=DVI

It can't be identified by the connector. Please see the pinned thread: https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?output=DVI

Generally motherboards only have single-link DVI. Dual-link and single-link ports cannot be identified by the connector. Please refer to the pinned guide. https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?output=DVI

It's not pedantry at all. As I mentioned, there are many instances of misunderstandings which are both genuine and common, and factually incorrect advice given about what cables are required, which are directly caused by this. And, one of them is people not knowing how to identify cables, even if the rating is printed in plain text right on the cable, because they're looking for something that says "version 1.4 cable" instead of "High Speed HDMI cable". And as long as people keep insisting "they're HDMI 1.4 cables" this will continue.

No HDMI version has a bandwidth requirement. They have bandwidth limits, which devices are not permitted to exceed. Anyway, bandwidth limits are not the only thing that changes with HDMI versions, nor do they change in every version, but they are the only thing that affect cable design, which is why cables are rated by bandwidth, not tied to specific "version numbers". For example VRR and HDR were only added in later HDMI versions, but will still work with a standard High Speed HDMI cable (what you would call an "HDMI 1.4" cable). If you call them "HDMI 1.4 cables" and "HDMI 2.1 cables" you imply that the "2.1 cable" is required for VRR because VRR is an HDMI 2.1 feature, and HDMI 1.4 doesn't support it, and indeed there are many people who think "if you want HDR you need an HDMI 2.0 cable because HDMI 1.4 doesn't support HDR". There are no HDMI 1.4 cables or HDMI 2.1 cables. There are High Speed HDMI cables and Ultra High Speed HDMI cables, rated for 10.2 Gbit/s and 48 Gbit/s respectively. You need a 48 Gbit/s rated cable if you need 48 Gbit/s bandwidth. If you don't, then you don't need one. Newer features that are not related to bandwidth will work on any HDMI cable, regardless of what version of the specification that feature was introduced and when the cable was made or what bandwidth it can handle. Cables only affect maximum bandwidth, which is why they are rated by bandwidth, not by "version number". @Jacobplayz_YT Any certified HDMI cable should have its rating printed on the cable jacket, such as "High Speed HDMI Cable With Ethernet". This is required by the HDMI licensing agreement. If it doesn't say anything, then it's an unlicensed product, and there's no way to know what it's capable of.

I haven't kept up on specific models for a few years now.

It's sometimes unpredictable how monitors will implement these aspect ratio controls, which makes it difficult to give general advice. The monitor may still be recongized as 3440×1440 and simply squish the image to 16:9. You can try it though and see what you get.

You need to use CVT Reduced Blank timing, not CVT. CVT is for CRT monitors and has very large amounts of overhead especially at high refresh frequencies, this causes a lot of bandwidth to be wasted and your maximum available refresh frequency will be lower.

If you have a game set to Fullscreen mode then it will take over control of the display whenever it's active and do its own thing. Try setting to borderless window mode, and set your desktop resolution to 2560×1440. Preserve Aspect Ratio with GPU Scaling enabled should work then.

Most modern 1080p monitors support at least 120 Hz over HDMI. You can check the user manual to find out which modes are supported on which interfaces. There's usually a table near the end.

FYI GeForce cards are limited to 4 displays. If you have a Radeon card then you're fine up to 6.

1080p 144 Hz only requires High Speed HDMI which should be fine at 10 m. But 1 cable per monitor.

@GOTSpectrum Same here

Check what ports your GPU has, check the pinned thread to see your options. https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/

An adapter that says "active adapter" in the product title or description.

Active adapters will work.

Hi, please start a new thread, do not hijack someone else's thread for your question

It's just my own observation based on experience, not something I read on the internet. Generally retail product listings (and even datasheets and manuals) can't be relied upon just by the fact that they label something as "Dual-Link DVI", because many there is a widespread belief that you can distinguish single-link from dual-link f by looking at the connector, which is not true. It seems there are some EVGA GT 710s that have two DVI ports and EVGA distinguishes between single-link and dual-link, so based on that, I trust that dual-link is indeed available on the GT 710. https://www.evga.com/Products/Specs/GPU.aspx?pn=F345C5EC-D00D-4818-9B43-79885E8A161F It says the maximum for DVI is 2560×1600, not 1920×1200. The limit of 1920×1200 at 60 Hz is only for single-link mode.

DVI ports on low-end cards are often single-link only (GT 1030 comes to mind). There's nothing in there about a limit of 60 Hz. If you mean where it says "Maximum resolution: 2560×1600 at 60 Hz", that just means that's the maximum resolution at that refresh rate. If you use a different refresh rate like 144 Hz then the maximum resolution will be different.
