LG 32GR93U-B vs 32GX850A-B: Which Wins?

If games and video are the priority while another LCD handles static work, buy the LG UltraGear 32GX850A-B OLED. Choose the LG UltraGear 32GR93U-B instead when this monitor must display fixed desktop elements all day, the room is bright, or any burn-in management would become a persistent worry.

Neither is a bad monitor; the deciding difference is whether you want the OLED’s substantially better picture or the IPS model’s lower-risk, more predictable desktop behavior.

The specification error that changes the comparison

The 32GX850A-B is not a 4K 240Hz monitor. LG specifies 4K at 165Hz or Full HD at 330Hz through its Dual Mode feature. The company’s complete specifications also identify a 31.5-inch glossy OLED panel, 3840 × 2160 resolution, 275 cd/m² typical brightness, and a claimed 1,300 cd/m² peak that applies only at 1.5% APL—a very small bright area. LG’s 32GX850A-B specifications

That makes the 4K refresh-rate difference only 21Hz: 165Hz versus 144Hz. Do not buy the OLED merely because a listing or comparison describes it as 240Hz. Its real advantages are per-pixel black control, much faster pixel transitions, glossy clarity, and convincing HDR—not a dramatic increase in 4K refresh rate.

The 1080p 330Hz mode is useful for competitive games when a PC can produce several hundred frames per second. On a 31.5-inch screen, however, 1080p is visibly softer than native 4K. It is an optional esports mode, not a reason to run ordinary games or desktop applications at the lower resolution.

What the OLED upgrade actually buys

OLED pixels produce their own light and can turn off individually. In a dark game or film, that gives the 32GX850A-B black pixels rather than the gray-black produced by an illuminated IPS panel. Bright objects can appear beside black without the halos associated with coarse LCD local dimming.

The Display Guy measured the exact 32GX850A-B at just under 700 nits in a 10% HDR window, under 300 nits full-screen, and roughly 400 nits in real scenes. Those results explain both sides of its performance: small highlights have impact, but a mostly white webpage or editing interface will not remain as bright as the IPS alternative. The review also recorded an average sRGB Delta E of 1.8. The Display Guy’s measured 32GX850A-B review

The 32GR93U-B is a capable gaming IPS monitor, but its DisplayHDR 400 badge should not be mistaken for OLED-like HDR. Les Numériques measured a contrast ratio of 1,183:1 and maximum brightness of 460 cd/m². It also measured 5ms persistence and 10.4ms input lag, confirming that it is responsive despite its unremarkable black level. Activating its sRGB mode brought measured Delta E down to 1.8.

RTINGS reached the same practical conclusion: the 32GR93U-B has low input lag and consistently fast response behavior, but its low contrast makes blacks look gray and its lack of local dimming prevents convincing HDR. RTINGS’ LG 32GR93U-B review

The 32GR93U-B is therefore the wrong purchase for a gaming-and-movie-first user who already has an LCD available for static work: its measured IPS contrast gives up the most visible OLED benefits without providing a meaningful 4K refresh-rate advantage.

How serious the OLED burn-in risk is

Burn-in is permanent uneven pixel aging, not merely a temporary ghost image. It is caused by repeatedly placing the same bright elements—taskbars, application controls, channel logos, game HUDs, or fixed editing panels—over the same pixels. There is no honest fixed number of hours after which it begins because brightness, content, temperature, panel variation, and care routines all affect wear.

LG equips the 32GX850A-B with OLED Screen Move, OLED Screen Saver, and OLED Image Cleaning. Its manual places those controls under Settings > General and says Image Cleaning takes about ten minutes. The routine runs automatically when the monitor enters power saving or turns off after more than four accumulated hours since the previous cleaning. LG’s 32GX850A-B support and manual page

Those systems reduce risk; they do not repeal the underlying aging process. Leave them enabled, use a short display-sleep timeout, avoid abandoning paused games or fixed windows at high brightness, and let the cleaning routine finish when prompted.

A useful long-term data point comes from a related LG 32-inch OLED, although it is not the same model and cannot predict the 32GX850A-B’s lifespan. Tom’s Hardware reported that an LG 32GS95UE-B showed faint Overwatch HUD retention after more than 3,000 hours of mixed use, including about 500 hours of that game. Peak brightness changed from 262 to 258 nits, while the retained elements were difficult to see outside deliberately chosen test screens. Tom’s Hardware’s report on the 3,000-hour OLED test

That result supports a measured conclusion: burn-in is real, but varied gaming and video use does not imply rapid, conspicuous failure. Eight or ten hours of the same desktop layout every working day is a materially different workload.

The warranty is not an unlimited burn-in promise

In the United States, LG lists two years of parts and labor coverage for the 32GX850A-B, compared with one year for the 32GR93U-B. Warranty terms vary by country, so check the policy for the exact regional suffix being purchased. LG’s US 32GX850A-B warranty page LG’s US 32GR93U-B warranty page

LG’s US OLED-monitor warranty excludes burned-in images resulting from improper usage as described in the owner’s manual. That wording is not an unconditional promise to replace every panel showing burn-in, and it leaves “improper usage” important to any claim. Keep proof of purchase, retain the default protection features, and do not treat the two-year hardware warranty as insurance against every possible usage pattern.

When the 32GR93U-B is the better purchase

Choose the IPS model when the same screen will spend most weekdays displaying an IDE, spreadsheet, editing timeline, browser chrome, monitoring dashboard, or fixed application arrangement. Its 31.5-inch 4K panel offers the same basic workspace and approximately the same pixel density as the OLED without cumulative organic-pixel wear.

The 32GR93U-B also has the more predictable presentation for large bright windows. LG specifies 400 cd/m² typical brightness, while the independent test reached 460 cd/m². The OLED’s full-screen brightness is lower and can change with the amount of bright content being displayed.

IPS is additionally easier to own if panel-care behavior would become distracting. There is no need to hide a taskbar, vary window placement, wait for an OLED cleaning cycle, or wonder whether a recurring game HUD is accumulating uneven wear.

The trade is visible every time a dark scene appears. The 32GR93U-B has no useful local dimming, so its backlight remains active behind black areas. Buy it for workload safety and desktop consistency, not because its HDR badge makes it equivalent to OLED.

Putting the OLED beside an IPS monitor

An OLED will not damage or technically interfere with an existing IPS monitor. The inconsistency is visual: dark material that looks black on the 32GX850A-B will look gray on the neighboring LCD. The OLED also has a glossy surface, whereas the 32GR93U-B uses an anti-glare treatment, so reflections and perceived sharpness will differ.

Calibration can align white point, color temperature, and ordinary SDR brightness. It cannot make an IPS panel reproduce OLED black, remove IPS glow, or make two different screen coatings look identical. Match the displays with measured luminance if possible; identical brightness-slider numbers do not represent identical output.

The most practical two-monitor arrangement is to give them different jobs. Put games, films, and full-screen video on the OLED. Keep email, browser windows, timelines, chat, and other fixed tools on the IPS display. This both reduces OLED wear and makes the contrast mismatch less distracting because one image is not being stretched across two fundamentally different panels.

PC and PS5 do not produce the same decision

For PC gaming, the OLED’s faster pixel response matters more than the jump from 144Hz to 165Hz. Motion remains clearer, especially through a variable-refresh range, and the 330Hz mode is available when competitive performance justifies dropping to 1080p.

For PS5, both monitors already exceed the console’s maximum 4K output of 120Hz and provide HDMI 2.1 connectivity. The OLED’s 165Hz ceiling and 330Hz mode therefore bring no refresh-rate benefit to PS5 games. Its console advantage is instead the black level, HDR presentation, and rapid OLED response.

The purchase rule

Buy the LG UltraGear 32GX850A-B when at least half of its use will be games, movies, or other changing full-screen content—particularly when a second LCD can carry prolonged office work. Burn-in risk remains, but that workload makes the OLED’s contrast, motion, and HDR advantages worth accepting.

Consider the LG UltraGear 32GR93U-B when it must be the only monitor for work and gaming, will show static interfaces for much of each day, sits in a bright environment, or needs to behave like an ordinary LCD without a care routine. It is the safer ownership decision, but it is not the equal-picture-quality alternative.
