You can use Adv. timing to modify default 240p mode parameters, but 348×240 output may not work well/at all because:

a) Sampling rate will be very low, possibly resulting to jitter
b) DVI/HDMI interface specifies min. 25MHz pixel clock which won’t then be achieved even with 2x pixel repetition

Switching from HDMI to DVI TX mode only makes pixel repetition implicit which is why capture card recognizes full width in DVI mode.
