KTC H24E8 / 24M1 Gaming Monitor Help: Setup, Light Shields, and 1440p

User manuals

Set up your KTC 24M1 (H24E8), attach the light shields, and choose a 1440p refresh rate that fits your connection. This guide also covers common display problems.

Quick Answers for the H24E8 / 24M1

The native resolution is 2560 x 1440 on a 23.8-inch display.
At 2560 x 1440, HDMI 2.0 supports up to 144Hz and DP 1.4 supports up to 240Hz.
An optional DP overclock can reach 260Hz; use 240Hz for the standard DP setup.
The box includes two light shields, a DP cable, and the base.

How Do I Assemble the Base and Light Shields?

Turn the monitor off and put it face down on a clean, soft, flat surface.
Align the base with the stand and secure it with the supplied fastener.
Insert the stand into the mounting slot on the rear of the monitor and check that it locks.
Align each light shield with the matching side slot, slide it inward, and press it down gently to secure it.
Lift the display by its body and stand, not the screen edge.

If a tab does not line up, check its orientation instead of forcing it. Keep the light shields clear of ventilation openings.

How Do I Connect a PC and Set 1440p at 240Hz?

Connect one direct DP cable from a compatible graphics output to a DP 1.4 input. Turn on the monitor and PC, choose the DP input with the monitor's menu, then set 2560 x 1440 and a refresh rate up to 240Hz in the PC's display settings. Begin at 60Hz if the picture is blank or unstable. HDMI 2.0 supports up to 144Hz at 1440p.

The source device, cable, and selected input must all support the chosen mode. If your monitor offers the optional 260Hz DP overclock, return to 240Hz if the picture becomes unstable.

How Do I Use the On-Screen Menu?

Use the monitor control to open the menu, choose the input matching your cable, and adjust brightness, gaming assistance, or picture presets. Adjust brightness before contrast when the image looks too dark or uncomfortable.

What Should I Check Before First Use?

The box includes the display, base, power adapter, DP signal cable, two light shields, and user guide with warranty card. Check the contents before assembly. Keep the screen protected on a soft surface, use the included power equipment, and first test with one direct signal cable. After the picture works normally, you can add a dock, switch, or adapter and check its supported 1440p mode separately.

How Do I Choose HDMI or DisplayPort?

Choose DP for 2560 x 1440 @ 240Hz or the optional 260Hz overclock. Choose HDMI if your device does not have DP and a 1440p mode up to 144Hz is sufficient. The monitor's input selection must match the connected cable. If a rate is missing from the PC's list, confirm the graphics port and cable specifications before changing monitor settings.

How Much Space Does the Monitor Need?

Leave about 10 cm of clearance at the sides and back and 30 cm above the display. Keep it on a stable desk, leave vents uncovered, and avoid heat, moisture, strong vibration, and direct air-conditioner airflow.

Troubleshooting H24E8 Problems

There is no power or picture

Check the outlet and supplied power equipment. If the monitor is on, select the connected input, reseat the cable, and test one direct connection at 1920 x 1080 @ 60Hz before returning to 1440p.

240Hz is not available

Confirm a DP 1.4 connection, 2560 x 1440 resolution, compatible graphics output and cable, and the PC's refresh-rate setting. HDMI supports up to 144Hz at that resolution.

The picture flickers or looks distorted

Lower the refresh rate, remove adapters or splitters for the test, and try another cable or input. Raise the setting only after the image is stable.

Frequently Asked Questions

Does the H24E8 run at 260Hz by default?

No. The regular 1440p DP mode reaches 240Hz; 260Hz is an optional overclock. Enable and test it only if your unit offers it.

Can I get 240Hz over HDMI?

No. HDMI 2.0 supports up to 144Hz at 2560 x 1440. Use DP 1.4 for 240Hz.

How should I clean the panel and shields?

Turn off and unplug the display. Wipe the screen gently with a soft, slightly damp cloth; do not spray liquid onto it. Check the shield attachment and vents while cleaning, and keep both free of dust.
