Late 2013 MacBook Pro Retina external monitor

I recently attached a Sceptre 4K IPS 27" 3840 x 2160 UHD Monitor up to 70Hz DisplayPort HDMI Model U275W-UPT) to my Late 2013 MacBook Pro Retina display using DP out to a lightning port. Is this monitor compatible with my MacBook pro? I'm having a lot of lag problems, freezes and crashes and I'm trying to pinpoint the problem.


MacBook Pro (Retina, 15-inch, Late 2013)

Processor 2.3 GHz Quad-Core Intel Corei7

Memory 16 GB 1600 MHz DDR3

Graphics NVIDIA GeForce GT750M 2GB

Big Sur 11.7.9


Thanks!

MacBook Pro 15″, macOS 11.7

That model appear to offer up to 2K resolution at reasonable refresh rates:


2nd Display Support: Dual/Mirroring* 2nd Max. Resolution: 2560x1600 (x2*)

Details:* This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt.

Alternately, it can support a single display up to 2560x1600 via Thunderbolt and

a single 1080p display at up to 60 Hz, 3840x2160 at 30 Hz, or 4096x2160 at 24 Hz via HDMI.

In general, supporting a large external display has only an imperceptible influence on Mac responsiveness.


That is because display data rates are so high, the servicing such a display using processing power is completely impossible.


Instead, a display-generator automaton is used for fetch the data from Display memory. The processor intervenes only once a screenful. To further reduce its impact your model MacBook Pro has 2 G Bytes of private display memory, so the impact of adding an external display is one lower.

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself.


The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.


You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.


Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, but are not inherently dangerous.
