Head-to-head
Dell S2725QS vs LG 27GR83Q: Dell favors fine 4K text, LG uses high frame rates at QHD
The short answer
Choose S2725QS for sharper 4K desktop text and detailed games. LG 27GR83Q suits fast competitive games where a capable PC can use 240Hz at QHD.
Before you choose
The reasoning and the trade-offs
Compare detail at the actual screen size
S2725QS works out to about 163.2 pixels per inch, versus 108.8 for 27GR83Q-B. A denser panel can draw finer text at the same logical size, while comfortable scaling determines workspace.
What this is based on
Pixels per inch = √(width² + height²) / diagonal. Inputs are 3840 × 2160 at 27 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.

Winner by situation
Start with what you need it to do
Read fine text and view 4K detail
S2725QS supplies 3840 × 2160 pixels against LG's 2560 × 1440. At the same 27-inch diagonal, Dell has the denser native image.

- Depends
Prioritize fast QHD gaming
27GR83Q offers 240 Hz at QHD, compared with Dell at 120 Hz in 4K. The game and PC must deliver enough frames to benefit from that ceiling.

- Depends
- LG UltraGear 27-inch QHD 240Hz
- Better fit
Prefer a 4K 120Hz balance
S2725QS combines 4K resolution with a 120 Hz limit. LG offers a higher refresh ceiling but cannot provide a native 4K image.

- Better fit
- LG UltraGear 27-inch QHD 240Hz
- Not suitable
Have a PC that can approach 240 frames per second
LG's 240 Hz mode provides twice the refresh opportunities of Dell's 120 Hz ceiling. Actual motion also depends on game frame delivery and pixel response.

What matters in practice
The differences that matter
Compare detail at the actual screen size
S2725QS works out to about 163.2 pixels per inch, versus 108.8 for 27GR83Q-B. A denser panel can draw finer text at the same logical size, while comfortable scaling determines workspace.
How we reached this conclusion
Pixels per inch = √(width² + height²) / diagonal. Inputs are 3840 × 2160 at 27 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.
Separate native detail from game speed
S2725QS draws 8.3 million native pixels per frame and 27GR83Q-B 3.7 million. Their refresh ceilings are 120Hz and 240Hz respectively.
How we reached this conclusion
Native pixels = width × height. Refresh interval =1000 / Hz, giving 8.3 and 4.2 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
The choice trades pixel workload for refresh opportunities
Dell uses 125% more native pixels, while LG offers twice the refresh ceiling.
How we reached this conclusion
3840 × 2160 / (2560 × 1440) = 2.25. 240 / 120 = 2. Neither ratio predicts measured game performance.
Choice A
Dell, S2725QS
27 Plus 4K Monitor
A 27-inch 4K screen with 120Hz refresh is a useful middle ground for sharp text, spreadsheets and relaxed gaming. Choose it for a desktop or a laptop that already has a dock.
- Best matched use
- Sharp desktop work with smoother scrolling
Checked facts
- 27-inch 3840 by 2160 IPS panel at 120Hz
- Two HDMI inputs and DisplayPort 1.4, with no USB-C video
- Height adjusts through 130 mm
Choice B
LG, 27GR83Q-B
UltraGear 27-inch QHD 240Hz
A 240Hz IPS monitor keeps the familiar 27-inch QHD layout while giving high-frame-rate games more room to run. HDMI 2.1 makes the input specification worth checking against your graphics card.
- Best matched use
- Fast QHD games on the same screen used for work
Checked facts
- 27-inch 2560 by 1440 IPS panel at 240Hz
- HDMI 2.1 and DisplayPort inputs
- 95 percent DCI-P3 coverage and a height-adjustable pivoting stand

What you give up
Every choice has a cost
If you choose Dell 27 Plus 4K Monitor
- Its speakers do not turn it into a webcam or conferencing monitor.
If you choose LG UltraGear 27-inch QHD 240Hz
- USB ports serve peripherals, not USB-C video or laptop charging.
What matters in practice
How to make the call
The Dell asks the GPU to shade more pixels
4K has 2.25 times the QHD pixel count. That is a workload comparison, not a guarantee that frame rate falls by the same factor.
The LG ceiling needs enough frames
240Hz can present a new refresh every 4.17 ms, while 120Hz gives 8.33 ms. Game frame time, response behavior and input latency still affect the result.
Neither is a one-cable laptop dock
Both lack USB-C video and charging in these records. Add the required display cable and separate charging plan for a laptop.
What this comparison cannot tell you
- Pixel density and refresh intervals are calculations from published specifications, not a measured visual-quality or latency test.
- USB-C power is a maximum negotiated ceiling. It does not promise full-speed charging for every laptop.
