The catch
Dell 27 Plus 4K Monitor
This model is the S2725QS, which has no USB-C video. Do not confuse it with the S2725QC.
Side by side
Dell S2725QS vs LG 27GR83Q: Fine 4K text suits Dell, while LG uses high frame rates at QHD
Quick verdict
Go for the S2725QS if you want sharper 4K desktop text and detailed games. The LG 27GR83Q suits fast competitive games where a capable PC can use 240Hz at QHD.
Before you buy
Why, and what it costs you
Detail should be compared at the actual screen size
S2725QS is about 163.2 pixels per inch, and 27GR83Q-B is 108.8. The denser panel can draw finer text at the same logical size, while workspace depends on comfortable scaling.
Where this comes from
Pixels per inch = √(width² + height²) / diagonal. Entered values are 3840 × 2160 at 27 inches and 2560 × 1440 at 27 inches. Using published nominal diagonals makes the results approximate.
The catch
LG UltraGear 27-inch QHD 240Hz
Setting 240Hz does not mean your games will render at 240 frames per second.

Look at fine text and 4K detail
Against LG's 2560 × 1440, S2725QS supplies 3840 × 2160 pixels. Dell has the denser native image at the same 27-inch diagonal.

Put fast QHD gaming first
Compared with Dell at 120 Hz in 4K, 27GR83Q offers 240 Hz at QHD. The game and PC have to deliver enough frames for that ceiling to pay off.

Want 4K and 120Hz in balance
In S2725QS, 4K resolution goes with a 120 Hz limit. LG has a higher refresh ceiling but cannot provide a native 4K image.

Own a PC that comes close to 240 frames per second
Compared with Dell's 120 Hz ceiling, LG's 240 Hz mode provides twice the refresh opportunities. How motion looks also depends on game frame delivery and pixel response.

In practice
Differences you will notice
Detail should be compared at the actual screen size
S2725QS is about 163.2 pixels per inch, and 27GR83Q-B is 108.8. The denser panel can draw finer text at the same logical size, while workspace depends on comfortable scaling.
How we worked this out
Pixels per inch = √(width² + height²) / diagonal. Entered values are 3840 × 2160 at 27 inches and 2560 × 1440 at 27 inches. Using published nominal diagonals makes the results approximate.
Keep native detail apart from game speed
Per frame, S2725QS draws 8.3 million native pixels and 27GR83Q-B draws 3.7 million. The refresh ceilings are 120Hz and 240Hz respectively.
How we worked this out
Native pixels = width × height. Refresh interval =1000 / Hz, which yields 8.3 and 4.2 ms. Treat these as signal and cadence calculations and not as measured frame rates, input lag or pixel response.
Pixel workload is traded for refresh opportunities in this choice
Native pixels run 125% higher on Dell, and the refresh ceiling on LG is twice as high.
How we worked this out
3840 × 2160 / (2560 × 1440) = 2.25 and 240 / 120 = 2. Measured game performance is not predicted by either ratio.
Option A
Dell, S2725QS

Trade-offs
What each pick costs you
With Dell 27 Plus 4K Monitor
- The speakers don't make it a conferencing monitor with a webcam.
With LG UltraGear 27-inch QHD 240Hz
- The USB ports are for peripherals and do not carry USB-C video or laptop charging.
Decision guide
How to decide
Pick the S2725QS for sharper 4K desktop text and detailed games, and the LG 27GR83Q for fast competitive games on a PC that can use 240Hz at QHD.
More pixels are left to the GPU to shade on the Dell
Pixel count at 4K is 2.25 times that of QHD. That compares workloads and does not guarantee that frame rate falls by the same factor.
The LG's ceiling takes enough frames
A new refresh can arrive every 4.17 ms at 240Hz, against 8.33 ms at 120Hz. Game frame time, response behavior and input latency still affect the result.
Neither works as a one-cable laptop dock
USB-C video and charging are missing from both in these records. For a laptop, add the required display cable and a separate charging plan.
What this page can’t tell you
- These pixel density and refresh interval figures are calculated from published specifications and do not come from a measured visual-quality or latency test.
- The USB-C power figure is the highest level that can be negotiated. It does not guarantee full-speed charging for every laptop.
