Getting the highest external resolution with my HP Spectre x360 2-in-1 Laptop 16

[lasitter]

I think this describes my 9C9B6USa laptop:

HP Spectre x360 2-in-1 Laptop 16, Windows 11 Pro, 16", Touch screen, Intel® Core™ Ultra 7, 16GB RAM, 2TB SSD, NVIDIA® GeForce RTX™ 4050, 2.8K, Nightfall black

I've been waiting over a year and finally saw this available on Amazon prime day:

SAMSUNG 34" ViewFinity S50GC Series Ultra-WQHD Monitor, 100Hz, 5ms, HDR10, AMD FreeSync, Eye Care, Borderless Design, PIP, PBP, LS34C502GANXZA, 2023, Black

It looked like a lot of monitor for just $208, so I bought it!

It has a resolution ratio of QHD Wide 1440p and aspec ratios of up to 21:9.

UWQHD (3,440 x 1,440

2 x HDMI 2.2 INPUTS plus 1 x DISPLAYPORT 1.2 INPUTS

So my question is: What do I need to have to get the most out of this as an external display with this laptop? I only want one external display.

Note: I plugged it in using the supplied HDMI cable and it works! Would it be any better using a HDMI to Display Port cable? Don't know. I guess it's really limited by the 1440 vertical in terms of the resolution -- still get much smaller / sharper text with the internal display, but it's a lot more desktop and certainly worth $200 ...

Hi @lasitter,

Welcome to the HP Support Community!

Thanks for reaching out!

I get how exciting it is to pair your new Samsung 34" UWQHD monitor with the HP Spectre x360 16 (RTX 4050), that’s a solid combo. Here’s how to get the most out of it:

Connection Options

HDMI 2.1 port on Spectre:

Your laptop supports HDMI 2.1, which can easily drive 3440 × 1440 at 100 Hz. Using the supplied HDMI cable is already optimal.

USB‑C / Thunderbolt 4:

You can also connect via USB‑C to DisplayPort using an adapter. This gives you DisplayPort 1.4 bandwidth, which is more than enough for UWQHD at high refresh rates.

DisplayPort vs HDMI:

For your monitor’s specs, HDMI 2.1 and DP 1.2/1.4 will perform the same. No need to buy a DP cable unless you prefer it.

Resolution & Scaling

Internal display: 2880 × 1800 (2.8K), sharper text due to higher pixel density.

External monitor: 3440 × 1440 (UWQHD), wider desktop space, but text will look less sharp compared to the laptop screen.

You can adjust Windows scaling (125–150%) to balance readability and sharpness.

With the RTX 4050, you can run games at native UWQHD smoothly.

Productivity apps (Word, Excel, and coding IDEs) benefit from the extra width, perfect for side‑by‑side multitasking.

Enable NVIDIA Control Panel custom resolution if you want to tweak refresh rates or scaling.

For best results, keep the monitor at native 3440 × 1440 and adjust scaling rather than forcing higher resolutions.

I hope this helps

Take care and have an amazing day ahead! 🚀

Best regards,
