Avoid misrepresented gaming monitors: ask for the panel model, EDID, firmware, and refresh proof to confirm claims like 165Hz on an Odyssey G5.

Stop guessing — verify the panel before you buy

If you’re hunting a deep discount on a gaming monitor like the Samsung Odyssey G5 or a similar high-refresh display, the listing often leaves out the single most important detail: the exact panel model. Sellers omit or misstate specs (refresh rate, response time, firmware) all the time — and those omissions cost buyers hundreds when a “165Hz 1ms” panel turns out to be a capped 120Hz VA or a refurbished unit with outdated firmware. This guide gives you the exact questions to ask, tools to use, and red flags to watch for so you don’t accidentally buy a misrepresented monitor.

Why panel model and firmware matter right now (2026 context)

In late 2025 and early 2026 the industry pivoted: manufacturers started shipping variant SKUs and frequent firmware updates that change behavior (VRR stability, overdrive profiles, pixel response). Marketplaces gradually added structured spec fields, but many listings still lack key verification details. That means the safest buyers are the ones who ask for hard proof — not marketing copy.

Pro tip: The panel model number is the single most reliable way to confirm what you’re getting. It reveals the manufacturer, pixel type (IPS/VA/TN), and often the native refresh and response characteristics.

Immediate checklist — what to ask the seller (fast, high-priority)

Panel model number (example format: M320QAN02.1 or LTM320AP01). Ask for the full code printed on the panel sticker — not the retail model name.
Monitor model code & serial (the retail SKU, e.g., LC32G55TQWNXZA) and a clear photo of the back sticker.
EDID dump or MonInfo/CRU output — raw data a PC reads that lists supported timings and max refresh rate.
Firmware version — screenshot of the OSD (On-Screen Display) page showing firmware/service version, or a photo of the service menu if accessible.
Video proof of refresh — a short phone video showing Windows display settings at the claimed refresh rate and the Blur Busters UFO Test running at that refresh.
Photos of the panel sticker (from the back with serial and manufacturing sticker) and the OSD main page.

Why each item matters

Panel model number

The panel code (not the retail model) tells you the true panel manufacturer and variant. Two retail models can use different panel suppliers; one may be 240Hz IPS, another 165Hz VA. If the seller can’t provide the panel code, walk away or insist on a strong return policy.

EDID dump

EDID is the monitor’s self-reported specifications. It lists supported resolutions and maximum refresh rate. If the listing claims 180Hz but the EDID lists 144Hz max, that’s a red flag. EDID is objective and hard to fake compared with a screenshot of Windows settings.

Firmware version

Firmware controls key features (VRR, overdrive, bug fixes). Some panels behave differently across firmware versions; a 2024 firmware may have scanline issues that 2025 fixes resolved. If the seller refuses to disclose firmware, you lose visibility on stability and warranty transfer issues.

How to get the evidence — step-by-step instructions for you or the seller

Use these platform-agnostic steps to request proof. Include the short templates below — they work in messages on eBay, Marketplace, Discord, or email.

1) Ask for a back-sticker photo showing the panel/serial

Request a clear photo of the monitor’s rear sticker. The sticker often contains a retail model/serial and sometimes the panel code.
Insist the photo include the monitor powered off next to a dated accessory (newspaper, phone lock-screen date) to avoid recycled images.

2) Get an EDID dump (easy, cross-platform methods)

EDID is the most powerful proof. Ask the seller to run one of these free tools and send the output file or screenshot.

Windows: MonInfo (EnTech) or Monitor Asset Manager. Both export a readable text dump.
Windows alternative: CRU (Custom Resolution Utility) shows current EDID and supported modes.
macOS: ask them to run a Terminal command: ioreg -lw0 | grep -i IODisplayEDID and paste the hex output, or send a screenshot of System Report > Graphics/Displays that shows pixel clock and timing info.
Linux: use xrandr --props or the read-edid tools to extract and paste the EDID block.

3) Show the OSD and firmware

Ask the seller to open the OSD menu and photograph the page that lists firmware/service version. If the OSD lacks firmware detail, ask for a picture of the “information” or “service” page.
If the seller can access the service menu (some models require a button combo), ask for that firmware screenshot — but don’t demand they do anything that risks bricking the unit.

4) Prove refresh rate live

Require a short vertical video (10–20 seconds) showing:

Windows (or macOS) display settings that show the selected refresh rate.
The Blur Busters UFO Test running; the test shows frame intervals and is a widely accepted verification tool.
If possible, a recording of the seller running FRAPS/RTSS or the in-game frame limiter showing the monitor running at the claimed Hz.

Practical message templates you can copy-paste

Initial verification request (short)

Hi — I’m interested but need to confirm a few details before buying. Can you please send: 1) a photo of the rear sticker showing the serial/model, 2) the panel model number (panel code), and 3) an EDID/MonInfo dump or screenshot of Windows showing the monitor’s max refresh? Thanks!

Escalation if the seller hesitates

I understand — if you’re not comfortable running tools, a clear photo of the back sticker plus a short video showing Windows display settings set to the claimed refresh and the Blur Busters test running will do. If you can’t provide any proof, I’ll need to pass unless the listing includes a full return policy.

Offer to pay a small fee for extra effort

If you run the MonInfo EDID dump and send it I’ll pay $10 extra to cover time. I’m ready to buy immediately with that proof.

How to interpret the proof sellers send

Panel code — what to look for

Panel codes are manufacturer strings. Common patterns include model-like sequences (e.g., M320QAN02.1 on some 32" panels). Look up the panel code online (search with quotes) — you should find forum posts or datasheets that confirm pixel type and native Hz. If search results return no matches, that’s a red flag.

EDID — the key fields

Detailed timing descriptors: show supported resolutions and refresh rates.
Established timings: confirm native modes.
Manufacturer ID & product code: can be cross-referenced with the sticker or serial.

If EDID lists a maximum of 144Hz but the seller claims 180Hz, the claim is false unless they can provide evidence of an overclock and its stability. Overclocking is not the same as native capability.

Firmware checks

Compare the firmware ID the seller provides against the manufacturer’s release notes. Firmware that dates before major bug-fixed builds (e.g., early 2024/2025 builds) is worth noting; ask whether the seller can or will update the firmware before shipping. If the seller refuses, check whether the manufacturer allows user firmware updates and whether updates are reversible.

Red flags and when to walk away

Seller refuses any live proof or only offers stock photos.
Mismatched info: EDID vs claimed spec don’t line up (e.g., EDID 144Hz vs listing 165/180Hz).
Panel code lookup turns up a cheaper/no-name panel or an older variant known for smear or slow response times.
Firmware information is vague and seller refuses to update or show the OSD.
Seller repeatedly claims “OC to 240Hz” but the EDID shows 165Hz max; overclock claims need real-world video proof.

Case study: Avoiding a misrepresented Odyssey G5

Situation: a listings shows “Samsung Odyssey G5 — 165Hz 1ms — like new” at a heavy discount. The buyer followed this guide’s process:

Requested panel code; seller provided a back photo showing a panel sticker with a code that search revealed as a generic 144Hz VA panel used in budget sets.
Seller sent a MonInfo EDID dump — it listed 144Hz max. The seller claimed “it can run 165Hz” but sent no proof of stable overclocking.
Buyer asked for firmware; seller sent an old service firmware build known to have VRR stutter (confirmed in forum changelog).

Result: buyer declined. They saved hundreds and avoided a monitor with poorer motion clarity and warranty ambiguity. This exact scenario is common in 2026 as component sourcing varies and panel mixes are more frequent.

What to do if you already bought the monitor and suspect misrepresentation

Run an EDID dump immediately. Compare the reported max refresh with the listing claims.
Record a video showing the OSD, the update list, and a Blur Busters test at the claimed rate.
If you find mismatches, contact the seller with evidence and request a return/refund under the platform’s buyer protection policy. Use the messages and attach your proof files.
If the seller won’t cooperate, open a formal dispute and include the EDID dump, firmware screenshot, and dated video as evidence.
Contact the manufacturer with the serial number to confirm warranty status and whether the unit’s panel is genuine.

Advanced verification: when to ask for lab-level tests

If you’re buying very cheaply and want to be extra-safe — or the monitor is a rare high-end panel — request:

A short high-frame-rate video using a high-shutter-speed camera (1200–2400 fps) of a moving pixel test to inspect response time. This is uncommon but definitive.
A live video call where the seller runs the MonInfo/CRU tools while you watch screen-share. This is the hardest to fake and excellent for high-value buys.

Checklist for the buyer — final pre-purchase verification

Photo of back sticker with serial and retail model.
Panel model number (panel code) confirmed.
EDID/MonInfo dump that matches claimed refresh rate.
OSD screenshot with firmware/service version.
Short video showing OS display refresh and Blur Busters test.
Clear return policy and proof that seller accepts returns for misrepresentation.

Future-proofing: trends to watch in 2026

More marketplaces will require structured spec fields and allow EDID uploads as proof — keep an eye on policies through 2026.
Manufacturers are increasingly assigning firmware release IDs in public changelogs — check these before you buy.
Panel mixing (same retail model with multiple panel suppliers) is a lasting trend; always verify the panel code rather than trusting the retail name.
AI-based image verification tools are becoming available for sellers to auto-attach EDID dumps; this will reduce friction for serious buyers.

Final rules of thumb

Always demand EDID or MonInfo output — it’s the least fuss and the most reliable proof.
Photos and videos must be dated and include something unique (a phone lock screen or newspaper) to avoid recycled images.
Firmware matters — don’t ignore it. Ask which firmware the seller has and whether the manufacturer still signs updates.
If it smells off, walk away. Cheap price with no proof is rarely a bargain — it’s risk.

Ready-made verification checklist & message pack

Use this final block as your copy-paste starter pack when you message a seller:

Message:
Hi — interested in the monitor. Please send:
1) Clear photo of the back sticker (retail model + serial) taken today.
2) Panel model code (panel sticker) or a close-up of the panel sticker.
3) MonInfo/CRU/EDID dump file or screenshot showing supported refresh rates.
4) OSD screenshot showing firmware/service version.
5) Short video (10–20s) showing Windows display set to the claimed refresh and the Blur Busters UFO test running.
I’ll buy immediately with that proof. Thanks!

Closing — take control of the purchase

Buying a discounted or secondhand monitor in 2026 can save serious money — but only if you verify the panel, refresh capability, response characteristics, and firmware before the sale. The tools and templates in this guide are designed for fast checks that most sellers can do in under 10 minutes. If a seller refuses, treat that as a meaningful risk sign.

Actionable takeaway: Never rely on the retail name alone. Ask for the panel code and EDID before you hand over funds — it’s the single step that prevents most misrepresented purchases.
